As skyscrapers continue to reach ever higher, elevators are required to carry more people further, faster. Mitsubishi already has the first problem licked with the development of elevators able to carry <a href="https://web.archive.org/web/20120531115341/http://www.gizmag.com/mitsubishi-electric-installs-five-enormous-elevators-holds-80-person-each/15139/" target="_blank">80 people at once</a>. Now it has tackled speed with technologies that enable ultra-high-speed elevators to travel at more than 60 km/h (37 mph or 1,000 meters a minute).</p> <p>The various technologies that Mitsubishi has developed to be incorporated into the world's fastest elevators include:</p> <ul><li>a single motor with two grouped three-phase winding coils and parallel drive systems that feature a built-in converter to regenerate electricity and cut power consumption by over 30 percent</li> <li>hydraulic driven clamp-type disk brakes</li> <li>lighter traveling cables enabled by encasing a wider diameter steel core in a lightweight sheath material</li> <li>a new active roller guide to reduce vibration from the guide rails and wind at ultra-high speeds</li> <li>streamlined aerodynamic car cover with a sound insulating cage.</li> <li>safety gear shoes constructed from fine ceramic to provide high resistance to heat, abrasion and shock and provide stability even if high frictional heat when the safety gear is activated</li> <li>air pressure control to minimize rapid changes in atmospheric pressure</li> </ul> <p>Mitsubishi says these technologies are being incorporated into elevators for the 632-meter (2,073 ft) Shanghai Tower currently under construction in China.</p> <p>Source: <a href="https://web.archive.org/web/20120531115341/http://www.mitsubishielectric.com/index.html" target="_blank">Mitsubishi</a> via <a href="https://web.archive.org/web/20120531115341/http://www.ubergizmo.com/2012/02/mitsubishi-fastest-elevator-in-the-world-at-60kph/" target="_blank">ubergizmo</a></p>  <div id="bottom_unit"> <script type="text/javascript" language="JavaScript"> </script> <script type="text/javascript" language="JavaScript" src="https://web.archive.org/web/20120531115341js_/http://pagead2.googlesyndication.com/pagead/show_ads.js"></script> </div> </div> <span class="title share_bar">Share</span> <div id="article_share_bar" class="dotsontop share_bar"> <span class="as_button fb_as_button"><fb:like href="http://www.gizmag.com/mitsubishi-ultra-high-speed-elevator/21324/" send="false" show_faces="false" font="" layout="box_count" id="facebook_like"></fb:like><script type="text/javascript">_ga.trackFacebook();</script></span> <span class="as_button"><a href="https://web.archive.org/web/20120531115341/http://twitter.com/share" class="twitter-share-button" data-count="vertical" data-via="gizmag">Tweet</a></span> <span class="as_button"><g:plusone size="tall" count="true" href="http://www.gizmag.com/mitsubishi-ultra-high-speed-elevator/21324/"></g:plusone></span> <span class="as_button"><su:badge layout="5"></su:badge></span> <span class="as_button"> <a href="https://web.archive.org/web/20120531115341/http://pinterest.com/pin/create/button/?url=http%3A%2F%2Fwww.gizmag.com%2Fmitsubishi-ultra-high-speed-elevator%2F21324%2F&media=http%3A%2F%2Fimages.gizmag.com%2Fhero%2Fshanghai_tower.jpg&description=Mitsubishi has developed new technologies that enable the construction of ultra-high-speed elevators able to travel at speeds of over 60 km/h (37 mph or 1,000 meters a second)." class="pin-it-button" count-layout="vertical"><img border="0" src="//web.archive.org/web/20120531115341im_/http://assets.pinterest.com/images/PinExt.png" title="Pin It"/></a> </span> <span class="as_button"><script type="IN/Share" data-counter="top"></script></span> <span class="as_button" id="reddit_button_bar"><script type="text/javascript">reddit_newwindow='1'</script></span> </div>   <div id="tags"> <span class="title">Tags</span> <div class="dotsontop"> <ul> <li>» <a href="/web/20120531115341/http://www.gizmag.com/tag/elevator/" rel="tag">Elevator</a></li> <li>» <a href="/web/20120531115341/http://www.gizmag.com/tag/mitsubishi/" rel="tag">Mitsubishi</a></li> <li class="clear_both"></li> </ul> </div> </div> <div id="bing_unit"></div>  <span class="title" id="comments">User Comments (7)</span> <div class="dotsontop" id="comment_dots">  <div id="comment-106828" class="a_comment"> <p>Thanks to the commenters who pointed out that 1,000 meters a second would obviously be quite a feat for an elevator.
