High-Speed Elevator

High-Speed Elevator

An exclusive group of structural engineers led by Professor of the Department of Civil and Environmental Engineering at the University of Yokohama developed and implemented a new high-speed elevator technology that uses a glass lift rod supported by elliptical rollers and counterweights at both the top and bottom of the elevator shaft. This unique system allows the elevator to provide the same benefits as other conventional elevators at the fraction of the cost. The three $4.3 million high-speed electric elevators (fromuay out of 79) at the famous Yokohama Landmark Tower in Tokyo, Japan, is the world's fastest, traveling at over 41 miles an hour, or four miles per hour. These elevators have revolutionized the way people travel and work in the big city.

The difference between an ordinary elevator and a high-speed elevator is quiet speed, smooth ride, and noise free movement. The reason for this is that these elevators are designed to operate at much higher speeds, or foot-per-second, than the sound barrier imposed by the local building code. This allows the high-speed elevator to move with the currents of the surrounding traffic at high speed, avoiding the noise, vibrations, and congestion that characterize conventional forms of mass-transit. These elevators have become a popular amenity in the business and corporate world. Many people have described the ride as being like floating in the air, with hardly any of the usual acoustics associated with typical forms of mass-transit.

While many of the technological advances made by the engineering team at the University of Yokohama have been deployed in commercial high-speed electric elevators in various business complexes and hotels around the world, there has been little effort put into research to incorporate these same technologies into the design of residential elevators. One possible solution is to use a shock absorbing foam that would allow the occupants of the high-speed elevator to absorb the shock when it passed over their feet. If this technology was perfected, there might be a way to eliminate the noise problem associated with most high-speed elevators by having them run on an independent power source and not relying on traditional fuels such as oil, natural gas, and electricity.
