Elevator lift

If you want to make or use a high-speed elevator, the most basic factor depends on the height of the building. In fact, a high-speed elevator has a process of acceleration and deceleration, and its acceleration is the same as that of a low-speed elevator. The final speed depends on the floor height and operating frequency.

After the high-speed elevator meets the above conditions, it must also meet the accurate calculation of the control system. Measurement system (such as grating, magnetic grating, tooth chewing, laser ranging, etc. ) must have extremely high precision, and the control system also needs to be able to handle huge and chaotic operations.

The servo system must be able to drag the elevator car slowly and smoothly, and the car must not accelerate or decelerate excessively.

Secondly, the installation of the guide rail must be very accurate, and the absolute deviation of the total length must be very small, which requires very high materials and construction technology. The car of the ultra-high-speed elevator must also conform to the aerodynamic principle, otherwise it will produce violent vibration at high speed.

In view of various factors, the level of production and installation, and the lack of technology, it is impossible for high-speed elevators to appear in any manufacturer, and it is extremely difficult to install high-speed elevators.

This means that if you want to use a high-speed elevator, the cost of the elevator will be high, and only a few places can afford it. ..

As far as the current international situation is concerned.

Autes Elevator Company, the first elevator manufacturer in the world, can reach the limit speed equivalent to more than 60 kilometers per hour.
