The technology developed by these industries, and the introduction of steel beam construction, worked together to provide the passenger and freight elevators in use today.

A safety system was designed to take effect if the cords broke, consisting of a beam pushed outwards by a steel spring.

The IGBT also allowed the development of a small, highly integrated, highly sophisticated all-digital control device, consisting of a high-speed processor, specially customized gate arrays, and a circuit capable of controlling large currents of several kHz.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-28">[28]</a> In 2000, the first vacuum elevator was offered commercially in Argentina.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-29">[29]</a> </section> <div class="mw-heading mw-heading2 section-heading" onclick="mfTempOpenSection(2)"> <h2 id="Design">Design</h2> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=4&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Design" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> <section class="mf-section-2 collapsible-block" id="mf-section-2"> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1251242444"> <table class="box-Unreferenced_section plainlinks metadata ambox ambox-content ambox-Unreferenced" role="presentation"> <tbody> <tr> <td class="mbox-text"> <div class="mbox-text-span"> This section does not <a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Citing_sources?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Citing sources">cite</a> any <a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Verifiability?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Verifiability">sources</a>.

An elevator is essentially a platform that is either pulled or pushed up by mechanical means. A modern-day elevator consists of a cab (also called a "cabin", "cage", "carriage" or "car") mounted on a platform within an enclosed space called a shaft or sometimes a "hoistway". In the past, elevator drive mechanisms were powered by steam and water hydraulic pistons or by hand. In a "traction" elevator, cars are pulled up by means of rolling steel ropes over a deeply grooved <a href="https://en-m-wikipedia-org.translate.goog/wiki/Pulley?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Pulley">pulley</a>, commonly called a sheave in the industry. The weight of the car is balanced by a <a href="https://en-m-wikipedia-org.translate.goog/wiki/Counterweight?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Counterweight">counterweight</a>. Oftentimes two elevators (or sometimes three) are built so that their cars always move synchronously in opposite directions, and are each other's counterweight. The friction between the ropes and the pulley furnishes the traction which gives this type of elevator its name. Hydraulic elevators use the principles of <a href="https://en-m-wikipedia-org.translate.goog/wiki/Hydraulics?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Hydraulics">hydraulics</a> (in the sense of <a href="https://en-m-wikipedia-org.translate.goog/wiki/Fluid_power?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Fluid power">hydraulic power</a>) to pressurize an above-ground or in-ground piston to raise and lower the car (see Hydraulic elevators below). Roped hydraulics use a combination of both ropes and hydraulic power to raise and lower cars. Recent innovations include permanent magnet motors, machine room-less rail mounted gearless machines, and microprocessor controls. The technology used in new installations depends on a variety of factors. Hydraulic elevators are cheaper, but installing cylinders greater than a certain length becomes impractical for very-high lift hoistways. For buildings of much over seven floors, traction elevators must be employed instead. Hydraulic elevators are usually slower than traction elevators.

The most common configuration is to have two panels that meet in the middle and slide open laterally. These are known as "center-opening". In a cascading telescopic configuration (potentially allowing wider entryways within limited space), the doors roll on independent tracks so that while open, they are tucked behind one another, and while closed, they form cascading layers on one side. This can be configured so that two sets of such cascading doors operate like the center opening doors described above, allowing for a very wide elevator cab. In less expensive installations the elevator can also use one large "slab" door: a single panel door the width of the doorway that opens to the left or right laterally. These are known as "single slide" doors. Some buildings have elevators with the single door on the shaftway, and double cascading doors on the cab. <div class="mw-heading mw-heading3"> <h3 id="Machine_room-less_(MRL)_elevators">Machine room-less (MRL) elevators</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=6&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Machine room-less (MRL) elevators" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> <figure class="mw-default-size" typeof="mw:File/Thumb"> <a href="https://en-m-wikipedia-org.translate.goog/wiki/File:Kone_EcoDisc.jpg?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-file-description"> <noscript> <img src="//upload.wikimedia.org/wikipedia/commons/thumb/8/87/Kone_EcoDisc.jpg/220px-Kone_EcoDisc.jpg" decoding="async" width="220" height="165" class="mw-file-element" data-file-width="2592" data-file-height="1944"> </noscript><span class="lazy-image-placeholder" style="width: 220px;height: 165px;" data-src="//upload.wikimedia.org/wikipedia/commons/thumb/8/87/Kone_EcoDisc.jpg/220px-Kone_EcoDisc.jpg" data-width="220" data-height="165" data-srcset="//upload.wikimedia.org/wikipedia/commons/thumb/8/87/Kone_EcoDisc.jpg/330px-Kone_EcoDisc.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/8/87/Kone_EcoDisc.jpg/440px-Kone_EcoDisc.jpg 2x" data-class="mw-file-element"> </a> <figcaption> <a href="https://en-m-wikipedia-org.translate.goog/wiki/Kone_EcoDisc?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Kone EcoDisc">Kone EcoDisc</a>.

Darrach (1846–1927) proposed the first formula to determine elevator service.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-34">[34]</a> In 1908, Reginald P. Bolton published the first book devoted to this subject, Elevator Service.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-35">[35]</a> The summation of his work was a massive fold-out chart (placed at the back of his book) that allowed users to determine the number of express and local elevators needed for a given building to meet a desired interval of service. In 1912, commercial engineer Edmund F. Tweedy and electrical engineer Arthur Williams co-authored a book titled Commercial Engineering for Central Stations.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-36">[36]</a> He followed Bolton's lead and developed a "Chart for determining the number and size of elevators required for office buildings of a given total occupied floor area". In 1920, Howard B. Cook presented a paper titled "Passenger Elevator Service".<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-37">[37]</a> This paper marked the first time a member of the elevator industry offered a mathematical means of determining elevator service. His formula determined the round trip time (RTT) by finding the single trip time, doubling it, and adding 10 seconds. In 1923, Bassett Jones published an article titled "The Probable Number of Stops Made by an Elevator".<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-38">[38]</a> He based his equations on the theory of probabilities and found a reasonably accurate method of calculating the average stop count.

Therefore, DC machines powered by an AC/DC <a href="https://en-m-wikipedia-org.translate.goog/wiki/Motor%E2%80%93generator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Motor–generator">motor generator</a> were the preferred solution.

The widespread availability of variable frequency AC drives has allowed AC motors to be used universally, bringing with it the advantages of the older motor-generator, DC-based systems, without the penalties in terms of efficiency and complexity. The older MG-based installations are gradually being replaced in older buildings due to their poor energy efficiency. Gearless traction machines are low-speed (low-RPM), high-<a href="https://en-m-wikipedia-org.translate.goog/wiki/Torque?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Torque">torque</a> electric motors powered either by AC or DC. In this case, the drive sheave is directly attached to the end of the motor. Gearless traction elevators can reach speeds of up to 20 m/s (4,000 ft/min), A brake is mounted between the motor and gearbox or between the motor and drive sheave or at the end of the drive sheave to hold the elevator stationary at a floor. This brake is usually an external <a href="https://en-m-wikipedia-org.translate.goog/wiki/Drum_brake?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Drum brake">drum type</a> and is actuated by spring force and held open electrically; a power failure will cause the brake to engage and prevent the elevator from falling (see <a href="https://en-m-wikipedia-org.translate.goog/wiki/Inherent_safety?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Inherent safety">inherent safety</a> and <a href="https://en-m-wikipedia-org.translate.goog/wiki/Safety_engineering?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Safety engineering">safety engineering</a>).

This action is powered by the traction machine which is directed by the controller, typically a relay logic or computerized device that directs starting, <a href="https://en-m-wikipedia-org.translate.goog/wiki/Acceleration?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Acceleration">acceleration</a>, <a href="https://en-m-wikipedia-org.translate.goog/wiki/Deceleration?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Deceleration">deceleration</a> and stopping of the elevator cab. The weight of the counterweight is typically equal to the weight of the elevator cab plus 40–50% of the capacity of the elevator. The grooves in the drive sheave are specially designed to prevent the cables from slipping. "<a href="https://en-m-wikipedia-org.translate.goog/wiki/Traction_(engineering)?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Traction (engineering)">Traction</a>" is provided to the ropes by the grip of the grooves in the sheave, thereby the name. As the ropes age and the traction grooves wear, some traction is lost and the ropes must be replaced and the sheave repaired or replaced. Sheave and rope wear may be significantly reduced by ensuring that all ropes have equal tension, thus sharing the load evenly. Rope tension equalization may be achieved using a rope tension gauge, and is a simple way to extend the lifetime of the sheaves and ropes. Elevators with more than 30 m (98 ft) of travel have a system called compensation. This is a separate set of cables or a chain attached to the bottom of the counterweight and the bottom of the elevator cab. This makes it easier to control the elevator, as it compensates for the differing weight of cable between the hoist and the cab. If the elevator cab is at the top of the hoist-way, there is a short length of hoist cable above the car and a long length of compensating cable below the car and vice versa for the counterweight. If the compensation system uses cables, there will be an additional sheave in the pit below the elevator, to guide the cables. If the compensation system uses chains, the chain is guided by a bar mounted between the counterweight tracks. <div class="mw-heading mw-heading4"> <h4 id="Regenerative_drives">Regenerative drives</h4> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=19&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Regenerative drives" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> Another energy-saving improvement is the regenerative drive,<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-52">[52]</a> which works analogously to <a href="https://en-m-wikipedia-org.translate.goog/wiki/Regenerative_braking?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Regenerative braking">regenerative braking</a> in vehicles, using the elevator's electric motor as a generator to capture some of the <a href="https://en-m-wikipedia-org.translate.goog/wiki/Gravitational_energy?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Gravitational energy">gravitational potential energy</a> of descent of a full cab (heavier than its counterweight) or ascent of an empty cab (lighter than its counterweight) and return it to the building's electrical system. <div class="mw-heading mw-heading3"> <h3 id="Hydraulic_elevators">Hydraulic elevators</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=20&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Hydraulic elevators" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> <figure class="mw-default-size" typeof="mw:File/Thumb"> <a href="https://en-m-wikipedia-org.translate.goog/wiki/File:Elevator_hydraulic.jpg?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-file-description"> <noscript> <img src="//upload.wikimedia.org/wikipedia/commons/thumb/c/c7/Elevator_hydraulic.jpg/220px-Elevator_hydraulic.jpg" decoding="async" width="220" height="165" class="mw-file-element" data-file-width="3264" data-file-height="2448"> </noscript><span class="lazy-image-placeholder" style="width: 220px;height: 165px;" data-src="//upload.wikimedia.org/wikipedia/commons/thumb/c/c7/Elevator_hydraulic.jpg/220px-Elevator_hydraulic.jpg" data-width="220" data-height="165" data-srcset="//upload.wikimedia.org/wikipedia/commons/thumb/c/c7/Elevator_hydraulic.jpg/330px-Elevator_hydraulic.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/c/c7/Elevator_hydraulic.jpg/440px-Elevator_hydraulic.jpg 2x" data-class="mw-file-element"> </a> <figcaption> Pit of a hydraulic scenic elevator with metal grating on bottom.

The propulsion can be done by an electric or a combustion engine. Climbing elevators are used in guyed masts or towers, in order to make easy access to parts of these constructions, such as flight safety lamps for maintenance. An example would be the <a href="https://en-m-wikipedia-org.translate.goog/wiki/Moonlight_tower?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Moonlight tower">moonlight towers</a> in Austin, Texas, where the elevator holds only one person and equipment for maintenance.

Temporary climbing elevators are commonly used in the construction of new high-rise buildings to move materials and personnel before the building's permanent elevator system is installed, at which point the climbing elevators are dismantled. <div class="mw-heading mw-heading3"> <h3 id="Pneumatic_elevator">Pneumatic elevator</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=23&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Pneumatic elevator" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> An elevator of this kind uses a vacuum on top of the cab and a valve on the top of the "shaft" to move the cab upwards and closes the valve in order to keep the cab at the same level. A diaphragm or a piston is used as a "brake", if there is a sudden increase in pressure above the cab. To go down, it opens the valve so that the air can pressurize the top of the "shaft", allowing the cab to go down by its own weight. This also means that in case of a power failure, the cab will automatically go down. The "shaft" is made of acrylic, and is always round due to the shape of the vacuum pump. To keep the air inside of the cab, rubber seals are used. Due to technical limitations, these elevators have a low capacity, they usually allow 1–3 passengers and up to 525 pounds (238 kg).<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-56">[56]</a> </section> <div class="mw-heading mw-heading2 section-heading" onclick="mfTempOpenSection(5)"> <h2 id="Controls">Controls</h2> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=24&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Controls" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> <section class="mf-section-5 collapsible-block" id="mf-section-5"> <div class="mw-heading mw-heading3"> <h3 id="Manual_controls">Manual controls</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=25&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Manual controls" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1251242444"> <table class="box-Unreferenced_section plainlinks metadata ambox ambox-content ambox-Unreferenced" role="presentation"> <tbody> <tr> <td class="mbox-text"> <div class="mbox-text-span"> This section does not <a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Citing_sources?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Citing sources">cite</a> any <a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Verifiability?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Verifiability">sources</a>.

Some of the older freight elevators were controlled by switches operated by pulling on adjacent ropes. In general, most elevators before WWII were manually controlled by <a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator_operator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Elevator operator">elevator operators</a> using a <a href="https://en-m-wikipedia-org.translate.goog/wiki/Rheostat?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Rheostat">rheostat</a> connected to the motor. This rheostat (see picture) was enclosed within a cylindrical container about the size and shape of a cake. This was mounted upright or sideways on the cab wall and operated via a projecting handle, which was able to slide around the top half of the cylinder. The elevator motor was located at the top of the shaft or beside the bottom of the shaft. Pushing the handle forward would cause the cab to rise; backwards would make it sink. The harder the pressure, the faster the elevator would move. The handle also served as a <a href="https://en-m-wikipedia-org.translate.goog/wiki/Dead_man_switch?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Dead man switch">dead man switch</a>: if the operator let go of the handle, it would return to its upright position, causing the elevator cab to stop. In time, safety interlocks would ensure that the inner and outer doors were closed before the elevator was allowed to move. This lever would allow some control over the energy supplied to the motor and so enabled the elevator to be accurately positioned—if the operator was sufficiently skilled. More typically, the operator would have to "jog" the control, moving the cab in small increments until the elevator was reasonably close to the landing point. Then the operator would direct the outgoing and incoming passengers to "watch the step". <figure class="mw-default-size" typeof="mw:File/Thumb"> <a href="https://en-m-wikipedia-org.translate.goog/wiki/File:Mit-old-elevator-panel.jpg?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-file-description"> <noscript> <img src="//upload.wikimedia.org/wikipedia/commons/thumb/5/5d/Mit-old-elevator-panel.jpg/170px-Mit-old-elevator-panel.jpg" decoding="async" width="170" height="227" class="mw-file-element" data-file-width="1704" data-file-height="2272"> </noscript><span class="lazy-image-placeholder" style="width: 170px;height: 227px;" data-src="//upload.wikimedia.org/wikipedia/commons/thumb/5/5d/Mit-old-elevator-panel.jpg/170px-Mit-old-elevator-panel.jpg" data-width="170" data-height="227" data-srcset="//upload.wikimedia.org/wikipedia/commons/thumb/5/5d/Mit-old-elevator-panel.jpg/255px-Mit-old-elevator-panel.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/5/5d/Mit-old-elevator-panel.jpg/340px-Mit-old-elevator-panel.jpg 2x" data-class="mw-file-element"> </a> <figcaption> Manual pushbutton elevator controls </figcaption> </figure> The Otis Autotronic system of the early 1950s brought the earliest predictive systems which could anticipate traffic patterns within a building to deploy elevator movement in the most efficient manner.

If the particular elevator is currently serving traffic in a certain direction, it will only answer calls in the same direction unless there are no more calls beyond that floor. In a group of two or more elevators, the call buttons may be linked to a central dispatch computer, such that they illuminate and cancel together. This is done to ensure that only one car is called at one time. Key switches may be installed on the ground floor so that the elevator can be remotely switched on or off from the outside.

The system lets them know which car to wait for, instead of everyone boarding the next car. In this way, travel time is reduced as the elevator makes fewer stops for individual passengers, and the computer distributes adjacent stops to different cars in the bank. Although travel time is reduced, passenger waiting times may be longer as they will not necessarily be allocated the next car to depart. During the down peak period the benefit of destination control will be limited as passengers have a common destination. It can also improve accessibility, as a mobility-impaired passenger can move to their designated car in advance. Inside the elevator there is no call button to push, or the buttons are there but they cannot be pushed—except door opening and alarm button—they only indicate stopping floors. The idea of destination control was originally conceived by <a href="https://en-m-wikipedia-org.translate.goog/wiki/Leo_Port?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Leo Port">Leo Port</a> from Sydney in 1961,<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-67">[67]</a> but at that time elevator controllers were implemented in relays and were unable to optimize the performance of destination control allocations. The system was first pioneered by <a href="https://en-m-wikipedia-org.translate.goog/wiki/Schindler_Group?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Schindler Group">Schindler Elevator</a> in 1992 as the Miconic 10. Manufacturers of such systems claim that average traveling time can be reduced by up to 30%.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-68">[68]</a> However, performance enhancements cannot be generalized as the benefits and limitations of the system are dependent on many factors.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-69">[69]</a> One problem is that the system is subject to gaming. Sometimes, one person enters the destination for a large group of people going to the same floor. The dispatching <a href="https://en-m-wikipedia-org.translate.goog/wiki/Algorithm?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Algorithm">algorithm</a> is usually unable to completely cater for the variation, and latecomers may find the elevator they are assigned to is already full. Also, occasionally, one person may press the floor multiple times. This is common with up/down buttons when people believe this to be an effective way to hurry elevators. However, this will make the computer think multiple people are waiting and will allocate empty cars to serve this one person. To prevent this problem, in one implementation of destination control, every user is given an <a href="https://en-m-wikipedia-org.translate.goog/wiki/RFID?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="RFID">RFID</a> card, for identification and tracking, so that the system knows every user call and can cancel the first call if the passenger decides to travel to another destination, preventing empty calls. The newest invention knows even where people are located and how many on which floor because of their identification, either for the purposes of evacuating the building or for security reasons.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-70">[70]</a> Another way to prevent this issue is to treat everyone traveling from one floor to another as one group and to allocate only one car for that group. The same destination scheduling concept can also be applied to public transit such as in <a href="https://en-m-wikipedia-org.translate.goog/wiki/Group_rapid_transit?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Group rapid transit">group rapid transit</a>. <figure class="mw-default-size" typeof="mw:File/Thumb"> <a href="https://en-m-wikipedia-org.translate.goog/wiki/File:DestinationDispatchElevator.jpg?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-file-description"> <noscript> <img src="//upload.wikimedia.org/wikipedia/commons/thumb/a/aa/DestinationDispatchElevator.jpg/170px-DestinationDispatchElevator.jpg" decoding="async" width="170" height="257" class="mw-file-element" data-file-width="3264" data-file-height="4928"> </noscript><span class="lazy-image-placeholder" style="width: 170px;height: 257px;" data-src="//upload.wikimedia.org/wikipedia/commons/thumb/a/aa/DestinationDispatchElevator.jpg/170px-DestinationDispatchElevator.jpg" data-width="170" data-height="257" data-srcset="//upload.wikimedia.org/wikipedia/commons/thumb/a/aa/DestinationDispatchElevator.jpg/255px-DestinationDispatchElevator.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/a/aa/DestinationDispatchElevator.jpg/340px-DestinationDispatchElevator.jpg 2x" data-class="mw-file-element"> </a> <figcaption> An Otis Compass <a href="https://en-m-wikipedia-org.translate.goog/wiki/Destination_dispatch?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Destination dispatch">destination dispatch</a> control station, outside of the car, on which the user presses a button to indicate the desired destination floor, and the panel indicates which car will be dispatched </figcaption> </figure> </section> <div class="mw-heading mw-heading2 section-heading" onclick="mfTempOpenSection(6)"> <h2 id="Special_operating_modes">Special operating modes</h2> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=31&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Special operating modes" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> <section class="mf-section-6 collapsible-block" id="mf-section-6"> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1251242444"> <table class="box-More_citations_needed_section plainlinks metadata ambox ambox-content ambox-Refimprove" role="presentation"> <tbody> <tr> <td class="mbox-text"> <div class="mbox-text-span"> This section needs additional citations for <a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Verifiability?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Verifiability">verification</a>.

Elevators are dispatched one-by-one when they reach a pre-determined passenger load, or when they have had their doors opened for a certain period of time. The next elevator to be dispatched usually has its hall lantern or a "this car leaving next" sign illuminated to encourage passengers to make maximum use of the available elevator system capacity. Some elevator banks are programmed so that at least one car will always return to the lobby floor and park whenever it becomes free. The commencement of up-peak may be triggered by a time clock, by the departure of a certain number of fully loaded cars leaving the lobby within a given time period, or by a switch manually operated by a building attendant. <div class="mw-heading mw-heading3"> <h3 id="Down-peak">Down-peak</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=34&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Down-peak" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> During down-peak mode, elevator cars in a group are sent away from the lobby towards the highest floor served, after which they commence running down the floors in response to hall calls placed by passengers wishing to leave the building.

For a tall building with many floors, the car must move on a frequent enough basis so as to not cause undue delay for potential users that will not touch the controls as it opens the doors on every floor up the building. <div class="mw-heading mw-heading3"> <h3 id="Independent_service">Independent service</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=36&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Independent service" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> Independent service or car preference is a special mode found on most elevators. It is activated by a key switch either inside the elevator itself or on a centralized control panel in the lobby. When an elevator is placed on this mode, it will no longer respond to hall calls. (In a bank of elevators, traffic is rerouted to the other elevators, while in a single elevator, the hall buttons are disabled). The elevator will remain parked on a floor with its doors open until a floor is selected and the door close button is held until the elevator starts to travel. Independent service is useful when transporting large goods or moving groups of people between certain floors. <div class="mw-heading mw-heading3"> <h3 id="Inspection_service">Inspection service</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=37&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Inspection service" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> Inspection service is designed to provide access to the hoistway and car top for inspection and maintenance purposes by qualified elevator mechanics. It is first activated by a key switch on the car operating panel usually labeled 'Inspection', 'Car Top', 'Access Enable' or 'HWENAB' (short for HoistWay access ENABled). When this switch is activated the elevator will come to a stop if moving, car calls will be canceled (and the buttons disabled), and hall calls will be assigned to other elevator cars in the group (or canceled in a single elevator configuration). The elevator can now only be moved by the corresponding 'Access' key switches, usually located at the highest (to access the top of the car) and lowest (to access the elevator pit) landings. The access key switches will allow the car to move at reduced inspection speed with the hoistway door open. This speed can range from anywhere up to 60% of normal operating speed on most controllers, and is usually defined by local safety codes. Elevators have a car top inspection station that allows the car to be operated by a mechanic in order to move it through the hoistway. Generally, there are three buttons: UP, RUN, and DOWN. Both the RUN and a direction button must be held to move the car in that direction, and the elevator will stop moving as soon as the buttons are released. Most other elevators have an up/down toggle switch and a RUN button. The inspection panel also has standard power outlets for work lamps and powered tools. <div class="mw-heading mw-heading3"> <h3 id="Fire_service">Fire service</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=38&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Fire service" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> Depending on the location of the elevator, fire service code will vary state to state and country to country. Fire service is usually split up into two modes: phase one and phase two. These are separate modes that the elevator can go into. Phase one mode is activated by a corresponding smoke sensor, heat sensor, or manual key switch in the building. Once an alarm has been activated, the elevator will automatically go into phase one. The elevator will wait an amount of time, then proceed to go into nudging mode to tell everyone the elevator is leaving the floor. Once the elevator has left the floor, depending on where the alarm was set off, the elevator will go to the fire-recall floor. However, if the alarm was activated on the fire-recall floor, the elevator will have an alternate floor to recall to. When the elevator is recalled, it proceeds to the recall floor and stops with its doors open. The elevator will no longer respond to calls or move in any direction. Located on the fire-recall floor is a fire-service key switch. The fire-service key switch has the ability to turn fire service off, turn fire service on or bypass fire service. The only way to return the elevator to normal service is to switch it to bypass after the alarms have reset. <figure class="mw-default-size" typeof="mw:File/Thumb"> <a href="https://en-m-wikipedia-org.translate.goog/wiki/File:KONE_Ecodisc_Elevator_in_Fireman%27s_Mode_(cropped).jpg?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-file-description"> <noscript> <img src="//upload.wikimedia.org/wikipedia/commons/thumb/d/d4/KONE_Ecodisc_Elevator_in_Fireman%27s_Mode_%28cropped%29.jpg/170px-KONE_Ecodisc_Elevator_in_Fireman%27s_Mode_%28cropped%29.jpg" decoding="async" width="170" height="227" class="mw-file-element" data-file-width="672" data-file-height="896"> </noscript><span class="lazy-image-placeholder" style="width: 170px;height: 227px;" data-src="//upload.wikimedia.org/wikipedia/commons/thumb/d/d4/KONE_Ecodisc_Elevator_in_Fireman%27s_Mode_%28cropped%29.jpg/170px-KONE_Ecodisc_Elevator_in_Fireman%27s_Mode_%28cropped%29.jpg" data-width="170" data-height="227" data-srcset="//upload.wikimedia.org/wikipedia/commons/thumb/d/d4/KONE_Ecodisc_Elevator_in_Fireman%27s_Mode_%28cropped%29.jpg/255px-KONE_Ecodisc_Elevator_in_Fireman%27s_Mode_%28cropped%29.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/d/d4/KONE_Ecodisc_Elevator_in_Fireman%27s_Mode_%28cropped%29.jpg/340px-KONE_Ecodisc_Elevator_in_Fireman%27s_Mode_%28cropped%29.jpg 2x" data-class="mw-file-element"> </a> <figcaption> KONE Ecodisc elevator in the United Kingdom in fireman's service mode </figcaption> </figure> Phase-two mode can only be activated by a key switch located inside the elevator on the car operating panel. This mode was created for firefighters so that they may rescue people from a burning building. The phase-two key switch has three positions: off, on, and hold. By turning phase two on, the firefighter enables the car to move. However, like independent-service mode, the car will not respond to a car call unless the firefighter manually pushes and holds the door close button. Once the elevator gets to the desired floor it will not open its doors unless the firefighter holds the door open button. This is in case the floor is burning and the firefighter can feel the heat and knows not to open the door. The firefighter must hold the door open button until the door is completely opened. If for any reason the firefighter wishes to leave the elevator, they will use the hold position on the key switch to make sure the elevator remains at that floor. If the firefighter wishes to return to the recall floor, they simply turn the key off and close the doors. In the UK and Europe the requirements for firefighters lifts are defined in the standard EN81-72.[<a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Citation_needed?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Citation needed">citation needed</a>] <div class="mw-heading mw-heading3"> <h3 id="Medical_emergency_or_code-blue_service">Medical emergency or code-blue service</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=39&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Medical emergency or code-blue service" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> Commonly found in hospitals, code-blue service allows an elevator to be summoned to any floor for use in an emergency situation. Each floor will have a code-blue recall key switch, and when activated, the elevator system will immediately select the elevator car that can respond the fastest, regardless of direction of travel and passenger load. Passengers inside the elevator will be notified with an alarm and indicator light to exit the elevator when the doors open. Once the elevator arrives at the floor, it will park with its doors open and the car buttons will be disabled to prevent a passenger from taking control of the elevator. Medical personnel must then activate the code-blue key switch inside the car, select their floor and close the doors with the door close button. The elevator will then travel non-stop to the selected floor, and will remain in code-blue service until switched off in the car. Some hospital elevators will feature a 'hold' position on the code-blue key switch (similar to fire service) which allows the elevator to remain at a floor locked out of service until code blue is deactivated. <div class="mw-heading mw-heading3"> <h3 id="Riot_mode">Riot mode</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=40&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Riot mode" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> In the event of civil disturbance, insurrection, or rioting, management can prevent elevators from stopping at the lobby or parking areas, preventing undesired persons from using the elevators while still allowing the building tenants to use them within the rest of the building. <div class="mw-heading mw-heading3"> <h3 id="Emergency_power_operation">Emergency power operation</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=41&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Emergency power operation" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> Many elevator installations now feature emergency power systems such as <a href="https://en-m-wikipedia-org.translate.goog/wiki/Uninterruptible_power_supply?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Uninterruptible power supply">uninterruptible power supply</a> (UPS) which allow elevator use in blackout situations and prevent people from becoming trapped in elevators.

The doors then close after an adjustable time period and the car remains unusable until reset, usually by cycling the elevator main power switch. Typically, due to the high current draw when starting the pump motor, hydraulic elevators are not run using standard emergency power systems. Buildings like hospitals and nursing homes usually size their emergency generators to accommodate this draw. However, the increasing use of current-limiting motor starters, commonly known as "soft-start" contactors, avoids much of this problem, and the current draw of the pump motor is less of a limiting concern. </section> <div class="mw-heading mw-heading2 section-heading" onclick="mfTempOpenSection(7)"> <h2 id="Modernization">Modernization</h2> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=44&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Modernization" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> <section class="mf-section-7 collapsible-block" id="mf-section-7"> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1251242444"> <table class="box-Unreferenced_section plainlinks metadata ambox ambox-content ambox-Unreferenced" role="presentation"> <tbody> <tr> <td class="mbox-text"> <div class="mbox-text-span"> This section does not <a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Citing_sources?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Citing sources">cite</a> any <a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Verifiability?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Verifiability">sources</a>.

As the elevator ages and equipment become increasingly difficult to find or replace, along with code changes and deteriorating ride performance, a complete overhaul of the elevator may be suggested to the building owners. A typical modernization consists of controller equipment, electrical wiring and buttons, position indicators and direction arrows, hoist machines and motors (including door operators), and sometimes door hanger tracks. Rarely are car slings, rails, or other heavy structures changed. The cost of an elevator modernization can range greatly depending on which type of equipment is to be installed. Modernization can greatly improve operational reliability by replacing electrical relays and contacts with solid-state electronics. Ride quality can be improved by replacing motor-generator-based drive designs with <a href="https://en-m-wikipedia-org.translate.goog/wiki/Variable-frequency_drive?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Variable-frequency drive">Variable-Voltage, Variable Frequency (V3F) drives</a>, providing near-seamless acceleration and deceleration.

Of the 20 to 30 elevator-related deaths each year, most of them are maintenance-related—for example, technicians leaning too far into the shaft or getting caught between moving parts, and most of the rest are attributed to other kinds of accidents, such as people stepping blindly through doors that open into empty shafts or being strangled by scarves caught in the doors.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-windypundit.com-73">[73]</a> While it is possible (though extraordinarily unlikely) for an elevator's cable to snap, all elevators in the modern era have been fitted with several safety devices which prevent the elevator from simply free-falling and crashing. An elevator cab is typically borne by 2 to 6 (up to 12 or more in high rise installations) <a href="https://en-m-wikipedia-org.translate.goog/wiki/Redundancy_(engineering)?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Redundancy (engineering)">redundant</a> hoist cables or belts, each of which is capable on its own of supporting the rated load of the elevator plus twenty-five percent more weight. In addition, there is a device which detects whether the elevator is descending faster than its maximum designed speed; if this happens, the device causes copper (or silicon nitride ceramic in high rise installations) brake shoes to clamp down along the vertical rails in the shaft, stopping the elevator quickly, but not so abruptly as to cause injury. This device, called the governor, was invented by <a href="https://en-m-wikipedia-org.translate.goog/wiki/Elisha_Graves_Otis?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Elisha Graves Otis">Elisha Graves Otis</a>.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-newyorker.com-74">[74]</a> For example, in 2007 an elevator at a Seattle children's hospital experienced cable failure, causing it to free-fall until its governor engaged.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-seattlepi.com-75">[75]</a> In addition, an oil/hydraulic or spring or polyurethane or telescopic oil/hydraulic buffer or a combination (depending on the travel height and travel speed) is installed at the bottom of the shaft (or in the bottom of the cab and sometimes also in the top of the cab or shaft) to somewhat cushion any impact.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-windypundit.com-73">[73]</a> Lethal accidents do occur, however: in 1989, seven people were killed at a hospital in <a href="https://en-m-wikipedia-org.translate.goog/wiki/L%27Hospitalet_de_Llobregat?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="L'Hospitalet de Llobregat">L'Hospitalet, Spain</a>, when the pulleys connecting the cables to the elevator cabin broke loose and the safety mechanism failed to activate, causing the elevator to plunge seven stories to the ground.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-76">[76]</a> A similar accident occurred in 2019 in <a href="https://en-m-wikipedia-org.translate.goog/wiki/Santos,_Brazil?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Santos, Brazil">Santos, Brazil</a>, killing four.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-77">[77]</a> <div class="mw-heading mw-heading3"> <h3 id="Hydraulic_elevators_3">Hydraulic elevators</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=47&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Hydraulic elevators" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1251242444"> <table class="box-Unreferenced_section plainlinks metadata ambox ambox-content ambox-Unreferenced" role="presentation"> <tbody> <tr> <td class="mbox-text"> <div class="mbox-text-span"> This section does not <a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Citing_sources?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Citing sources">cite</a> any <a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Verifiability?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Verifiability">sources</a>.

Single bulkhead cylinders, typically built prior to a 1972 ASME A17.1 Elevator Safety Code change requiring a second dished bulkhead, were subject to possible <a href="https://en-m-wikipedia-org.translate.goog/wiki/Catastrophic_failure?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Catastrophic failure">catastrophic failure</a>.

In the event of a cylinder breach, the fluid loss results in uncontrolled down movement of the elevator. This creates two significant hazards: being subject to an impact at the bottom when the elevator stops suddenly and being in the entrance for a potential shear if the rider is partly in the elevator. Because it is impossible to verify the system at all times, the code requires periodic testing of the pressure capability. Another solution to protect against a cylinder blowout is to install a plunger gripping device. Two commercially available are known by the marketing names "LifeJacket" and "HydroBrake". The plunger gripper is a device which, in the event of an uncontrolled downward acceleration, nondestructively grips the plunger and stops the car. A device known as an overspeed or rupture valve is attached to the hydraulic inlet/outlet of the cylinder and is adjusted for a maximum flow rate. If a pipe or hose were to break (rupture), the flow rate of the rupture valve will surpass a set limit and mechanically stop the outlet flow of <a href="https://en-m-wikipedia-org.translate.goog/wiki/Hydraulic_fluid?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Hydraulic fluid">hydraulic fluid</a>, thus stopping the plunger and the car in the down direction.

Freight elevators are generally required to display a written notice in the car that the use by passengers is prohibited (though not necessarily illegal), though certain freight elevators allow dual use through the use of an inconspicuous riser. In order for an elevator to be legal to carry passengers in some jurisdictions it must have a solid inner door. Freight elevators are typically larger and capable of carrying heavier loads than a passenger elevator, generally from 2,300 to 4,500 kg (5,100 to 9,900 lb). Freight elevators may have manually operated doors, and often have rugged interior finishes to prevent damage while loading and unloading.[<a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Citation_needed?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Citation needed">citation needed</a>] <div class="mw-heading mw-heading3"> <h3 id="Sidewalk_elevators">Sidewalk elevators</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=54&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Sidewalk elevators" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> A sidewalk elevator is a special type of freight elevator.

They may have unique design characteristics suited for home furnishings, such as hinged wooden shaft-access doors rather than the typical metal sliding doors of commercial elevators.

This section allows for different parameters to alleviate design complexity based on the limited use of a residential elevator by a specific user or user group. Section 5.3 of the ASME A17.1 Safety Code is for Private Residence Elevators, which does not include multi-family dwellings.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-82">[82]</a> Some types of residential elevators do not use a traditional elevator shaft, machine room, and elevator hoistway. This allows an elevator to be installed where a traditional elevator may not fit, and simplifies installation. The ASME board first approved machine-room-less systems in a revision of the ASME A17.1 in 2007. Machine-room-less elevators have been available commercially since the mid-1990s, however cost and overall size prevented their adoption to the residential elevator market until around 2010.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-83">[83]</a> Also, residential elevators are smaller than commercial elevators.

They often connect kitchens to rooms on other floors. They usually do not have the same safety features found in passenger elevators, like various ropes for redundancy. They have a lower capacity, and they can be up to 1 metre (3 ft) tall. Control panels at every stop mimic those found in passenger elevators, allowing calling, door control and floor selection. <div class="mw-heading mw-heading3"> <h3 id="Paternoster">Paternoster</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=64&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Paternoster" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"> <div role="note" class="hatnote navigation-not-searchable"> Main article: <a href="https://en-m-wikipedia-org.translate.goog/wiki/Paternoster_elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Paternoster elevator">Paternoster elevator</a> </div> <figure class="mw-default-size" typeof="mw:File/Thumb"> <a href="https://en-m-wikipedia-org.translate.goog/wiki/File:BMF_Paternoster.jpg?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-file-description"> <noscript> <img src="//upload.wikimedia.org/wikipedia/commons/thumb/3/3a/BMF_Paternoster.jpg/170px-BMF_Paternoster.jpg" decoding="async" width="170" height="227" class="mw-file-element" data-file-width="2448" data-file-height="3264"> </noscript><span class="lazy-image-placeholder" style="width: 170px;height: 227px;" data-src="//upload.wikimedia.org/wikipedia/commons/thumb/3/3a/BMF_Paternoster.jpg/170px-BMF_Paternoster.jpg" data-width="170" data-height="227" data-srcset="//upload.wikimedia.org/wikipedia/commons/thumb/3/3a/BMF_Paternoster.jpg/255px-BMF_Paternoster.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/3/3a/BMF_Paternoster.jpg/340px-BMF_Paternoster.jpg 2x" data-class="mw-file-element"> </a> <figcaption> A <a href="https://en-m-wikipedia-org.translate.goog/wiki/Paternoster_lift?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Paternoster lift">paternoster</a> in <a href="https://en-m-wikipedia-org.translate.goog/wiki/Berlin?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Berlin">Berlin</a>, Germany </figcaption> </figure> A special type of elevator is the <a href="https://en-m-wikipedia-org.translate.goog/wiki/Paternoster_lift?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Paternoster lift">paternoster</a>, a constantly moving chain of boxes.

Since the early 1980s, some elevators feature voice synthesis to announce floor landings, car direction and special messages to passengers.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-91">[91]</a> OTIS is well known for this in some of their GEN2 model elevators. In addition to the call buttons, elevators usually have floor indicators (often illuminated by <a href="https://en-m-wikipedia-org.translate.goog/wiki/LED?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="LED">LED</a>) and direction lanterns. The former are almost universal in cab interiors with more than two stops and may be found outside the elevators as well on one or more of the floors. Floor indicators can consist of a <a href="https://en-m-wikipedia-org.translate.goog/wiki/Dial_(measurement)?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Dial (measurement)">dial</a> with a rotating <a href="https://en-m-wikipedia-org.translate.goog/wiki/Measuring_instrument?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Measuring instrument">needle</a>, but the most common types are those with successively illuminated floor indications or <a href="https://en-m-wikipedia-org.translate.goog/wiki/Liquid_crystal_display?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Liquid crystal display">LCDs</a>. Likewise, a change of floors or an arrival at a floor is indicated by a sound, depending on the elevator. Some buildings use proximity technology that recognizes residents and brings the elevator to ground level.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-92">[92]</a> Direction lanterns are also found both inside and outside elevator cars, but they should always be visible from outside because their primary purpose is to help people decide whether or not to get on the elevator. If somebody waiting for the elevator wants to go up, but a car comes first that indicates that it is going down, then the person may decide not to get on the elevator. If the person waits, then one will still stop going up. Direction indicators are sometimes etched with arrows or shaped like arrows and/or use the convention that one that lights up red means "down" and green (or white) means "up". Since the color convention is often undermined or over-ridden by systems that do not invoke it, it is usually used only in conjunction with other differentiating factors. An example of a place whose elevators use only the color convention to differentiate between directions is the <a href="https://en-m-wikipedia-org.translate.goog/wiki/Museum_of_Contemporary_Art,_Chicago?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Museum of Contemporary Art, Chicago">Museum of Contemporary Art</a> in Chicago, where a single circle can be made to light up green for "up" and red for "down". Sometimes directions must be inferred by the position of the indicators relative to one another. In addition to lanterns, most elevators have a chime to indicate if the elevator is going up or down either before or after the doors open, usually in conjunction with the lanterns lighting up. For example, one chime can indicate "up", two "down", and no chimes indicate an elevator that is 'free'.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-93">[93]</a>[<a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Citation_needed?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Citation needed"><span title="While not uncommon, 'most' is questionable at best, personal experience is that most elevators do *not* audibly indicate direction, and many that do actual use spoken words, and if this is a universal standard, a cite is needed.

It stabilizes the condition of the air inside the elevator car. Some elevator air conditioners can be used in countries with cold climates if a thermostat is used to reverse the refrigeration cycle to warm the elevator car. Heat generated from the cooling process is dissipated into the hoistway. The elevator cab (or car) is ordinarily not air-tight, and some of this heat may reenter the car and reduce the overall cooling effect. The air from the lobby constantly leaks into the elevator shaft due to elevator movements as well as elevator shaft ventilation requirements. Using this conditioned air in the elevator does not increase energy costs. However, by using an independent elevator air conditioner to achieve better temperature control inside the car, more energy will be used. Air conditioning poses a problem to elevators because of the condensation that occurs. The condensed water produced has to be disposed of; otherwise, it would create flooding in the elevator car and hoistway. <div class="mw-heading mw-heading4"> <h4 id="Methods_of_removing_condensed_water">Methods of removing condensed water</h4> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=71&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Methods of removing condensed water" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> There are at least four ways to remove condensed water from the air conditioner. However, each solution has its pros and cons. <div class="mw-heading mw-heading4"> <h4 id="Atomizing">Atomizing</h4> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=72&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Atomizing" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> Atomizing, also known as misting the condensed water, is one way to dispose of the condensed water. Spraying ultra-fine water droplets onto the hot coils of the air conditioner ensures that the condensed water evaporates quickly. Though this is one of the best methods to dispose of the condensed water, it is also one of the costliest because the nozzle that atomizes the water easily gets choked. The majority of the cost goes to maintaining the entire atomizing system. <div class="mw-heading mw-heading4"> <h4 id="Boiling">Boiling</h4> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=73&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Boiling" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> Disposing of condensed water works by firstly collecting the condensed water and then heating it to above boiling point. The condensed water is eventually evaporated, thereby disposing of it. Consumers are reluctant to employ this system because of the high rate of energy used just to dispose of this water. <div class="mw-heading mw-heading4"> <h4 id="Cascading">Cascading</h4> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=74&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Cascading" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> The cascading method works by flowing the condensed water directly onto the hot coils of the air conditioner. This eventually evaporates the condensed water. The downside of this technology is that the coils have to be at extremely high temperature for the condensed water to be evaporated. There is a chance that the water might not evaporate entirely and that would cause water to overflow onto the exterior of the car. <div class="mw-heading mw-heading4"> <h4 id="Drainage_system">Drainage system</h4> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=75&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Drainage system" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> Drainage system works by creating a sump to collect the condensed water and using a pump to dispose of it through a drainage system. It is an efficient method, but it comes at a heavy price because of the cost of building the sump. Moreover, maintaining the pump to make sure it operates is very expensive. Furthermore, the pipes used for drainage would look ugly on the exterior. This system also cannot be implemented on a built project. </section> <div class="mw-heading mw-heading2 section-heading" onclick="mfTempOpenSection(12)"> <h2 id="ISO_22559">ISO 22559</h2> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=76&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: ISO 22559" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> <section class="mf-section-12 collapsible-block" id="mf-section-12"> <figure class="mw-default-size" typeof="mw:File/Thumb"> <a href="https://en-m-wikipedia-org.translate.goog/wiki/File:Elevator_(AIGA_based).svg?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-file-description"> <noscript> <img src="//upload.wikimedia.org/wikipedia/commons/thumb/e/ec/Elevator_%28AIGA_based%29.svg/110px-Elevator_%28AIGA_based%29.svg.png" decoding="async" width="110" height="183" class="mw-file-element" data-file-width="300" data-file-height="500"> </noscript><span class="lazy-image-placeholder" style="width: 110px;height: 183px;" data-src="//upload.wikimedia.org/wikipedia/commons/thumb/e/ec/Elevator_%28AIGA_based%29.svg/110px-Elevator_%28AIGA_based%29.svg.png" data-width="110" data-height="183" data-srcset="//upload.wikimedia.org/wikipedia/commons/thumb/e/ec/Elevator_%28AIGA_based%29.svg/165px-Elevator_%28AIGA_based%29.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/e/ec/Elevator_%28AIGA_based%29.svg/220px-Elevator_%28AIGA_based%29.svg.png 2x" data-class="mw-file-element"> </a> <figcaption> A international symbol for elevator </figcaption> </figure> The mechanical and electrical design of elevators is dictated according to various standards (aka elevator codes), which may be international, national, state, regional or city based.

Tenants of even-numbered floors first take an escalator (or an elevator from the parking garage) to the 2nd level, where they will enter the upper deck and arrive at their floors. The lower deck is turned off during low-volume hours, and the upper deck can act as a single-level elevator stopping at all adjacent floors. For example, the 85th floor restaurants can be accessed from the 60th floor sky-lobby. Restaurant customers must clear their reservations at the reception counter on the 2nd floor. A bank of express elevators stop only on the sky lobby levels (36 and 60, upper-deck car), where tenants can transfer to "local" elevators. The high-speed observation deck elevators accelerate to a former world-record certified speed of 1,010 metres per minute (61 km/h) in 16 seconds, and then it slows down for arrival with subtle air pressure sensations. The door opens after 37 seconds from the 5th floor. Special features include aerodynamic car and counterweights, and cabin pressure control to help passengers adapt smoothly to pressure changes. The downwards journey is completed at a reduced speed of 600 meters per minute, with the doors opening at the 52nd second. Many high speed elevators also have aerodynamic cab exteriors.<a href="https://en-m-wikipedia-org.translate.goog/wiki/Elevator?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-110">[110]</a> <div class="mw-heading mw-heading3"> <h3 id="Gateway_Arch">Gateway Arch</h3> <a role="button" href="https://en-m-wikipedia-org.translate.goog/w/index.php?title=Elevator&action=edit&section=83&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Edit section: Gateway Arch" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> edit </a> </div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"> <div role="note" class="hatnote navigation-not-searchable"> Main article: <a href="https://en-m-wikipedia-org.translate.goog/wiki/Gateway_Arch?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Gateway Arch">Gateway Arch</a> </div> <figure class="mw-default-size" typeof="mw:File/Thumb"> <a href="https://en-m-wikipedia-org.translate.goog/wiki/File:Gateway_Arch_tram_car.JPG?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-file-description"> <noscript> <img src="//upload.wikimedia.org/wikipedia/commons/thumb/8/8f/Gateway_Arch_tram_car.JPG/170px-Gateway_Arch_tram_car.JPG" decoding="async" width="170" height="255" class="mw-file-element" data-file-width="800" data-file-height="1200"> </noscript><span class="lazy-image-placeholder" style="width: 170px;height: 255px;" data-src="//upload.wikimedia.org/wikipedia/commons/thumb/8/8f/Gateway_Arch_tram_car.JPG/170px-Gateway_Arch_tram_car.JPG" data-width="170" data-height="255" data-srcset="//upload.wikimedia.org/wikipedia/commons/thumb/8/8f/Gateway_Arch_tram_car.JPG/255px-Gateway_Arch_tram_car.JPG 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/8/8f/Gateway_Arch_tram_car.JPG/340px-Gateway_Arch_tram_car.JPG 2x" data-class="mw-file-element"> </a> <figcaption> The interior of one of the Gateway Arch tramway cars </figcaption> </figure> The Gateway Arch in <a href="https://en-m-wikipedia-org.translate.goog/wiki/St._Louis?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="St. Louis">St. Louis</a> uses a unique tram system to transport visitors to the observation deck.
