Hitachi to build the fastest elevator in the world
#1


   

Japanese Hitachi said it will build an elevator that can accelerate to a speed of 72 km / hour in a skyscraper in southern China.

Hitachi say they provide lift comfortable journey for the user, even though the high-speed movement. Thus, the elevator system will be implemented that would avoid laying ears on the move up through alignment of cabin pressure. 

It has developed special rollers in the elevator, which will escalate pressure in the cabin, as well as mechanisms to support the cab, which will provide smooth acceleration and deceleration of the cabin. And during the braking mechanism will be heated to high temperatures, so the engineers had to use a heat-resistant pads. Total Chinese skyscraper will have 95 lifts, two of which are ultra-high-speed.
