In recent years, with rapid development of the economy, many Asian metropolitan areas have had an upsurge in super high buildings. In particular in China, buildings with a height of more than 300m are constantly springing up. The construction of super high buildings provides effective land-use for densely populated urban areas, which facilitates people's living and commercial activities. Among these, "longitudinal mobile infrastructure" -- elevators are essential.
免费高清电影 Hitachi Elevator installed elevators with the highest speed (300m/min), at that time, in the late 1960 's for the pioneer "Kasumidasek Building". Since then, Hitachi Elevator has been committed to developing "super high-speed and large capacity" elevators. Unlike conventional vertical elevators, "super high-speed and large capacity" elevators need to maintain safety, comfort and reliability in a limited shaft, limit loads and speeds as a result of integrated elevator technology. The birth of super high speed elevators has also produced a new encyclopedia on elevator technology. The super high speed elevator technology of Hitachi Elevator is one of those models.
The Power for the Highest Speed in the World
Technology of Ensuring Safety
Meticulous and Scientific Comfort
免费高清电影 With the increase of speed, tractor supplying power, and each part carrying power output will be challenged in terms of volume, toughness, life, and so on, due to the increase in output strength. For this purpose, our super high-speed elevator needs to be tailored by research and development. Taking the world's highest-speed elevator (used in CTF Finance Center) as an example, we have developed a leading global technological achievement.

BHigh Strength and Light Weight of Steel Wire Ropes
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.

免费高清电影 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.
