Super High Speed Projects

The elevator runs at a super high speed, generates more operational loads, and provides greater challenges to the safety performance of the elevator. In this regard, we carefully study and apply leading technology to ensure that the operation of the elevator is within the scope of safety.

• ABraking Material that can Resistant Temperatures above 300 Degrees Celsius.

  Hitachi has developed a completely new, high temperature resistant material, even if the brake creates a temperature above 300 degrees Celsius during braking. It can still safely stop the elevator from falling in an emergency.

• BSafe Braking even if all Steel Wire Ropes are Broken

  Although one wire rope is sufficient to pull the weight of N cars, and there are dozens of such wire ropes together, we cannot ignore extreme conditions. The emergency brake device, developed by us, can ensure that even if every steel wire rope breaks at high speed, the elevator can still be safely braked.

When the car is running at high speed in a closed shaft, air flow outside the car will cause a change of air pressure inside the car. Any microscopic vibration will be amplified due to the high-speed motion. For this, our super high speed elevators must be exact and scientific during the operation process, taking the whole process into account. Hitachi's new technology for car movement has also been applied to the world's highest speed elevator.

• ADynamic Car Air Pressure Control

  Through a simulator, the super high speed elevator can control air pressure in the car in stages, according to the actual running state of the elevator, to fully, automatically relieve possible tinnitus and ear pressure discomfort for passengers.

• BStreamlined Capsule Design, Creating a Quieter Car Space

  On the basis of past experience, we have developed a streamlined capsule structure for the car, which enables elevator movement to be more stable, comparable to a high-speed train, quiet and comfortable.
