Elevator accessories escort the elevator

In case of sudden power failure or phase loss in the operation of the elevator itself, the equipment will start with delay. By pulling the car to the flat floor with adjustable low speed, the car door and hall door will be automatically opened when the elevator reaches the designated position safely, which provides technical guarantee for passengers to leave the car safely. When the elevator is working normally, the device is in hibernation state. Once it is not running smoothly, the compensation chain guide device can make the elevator reach the designated position smoothly and safely through the elevator control system, open the door of the car, and eliminate the elevator accident caused by unexpected power failure and other reasons.

In recent years, according to the industrial development trend and the requirements of new industrialization development, actively guide the elevator parts industry to scale, high-speed, intelligent, energy saving and environmental protection direction development, has formed the elevator parts industry plate with the characteristics of the "four modernization". First, industrial scale. Second, the elevator is high-speed. With the development of multi-purpose and full-function high-rise buildings, high-speed elevator will be one of the development directions of the elevator industry in the future. Third, the elevator is intelligent.

Large enterprises generally pay attention to the application of new technologies and the improvement of independent development ability. After completing the construction of world-class modern factories, they set about building high-level research and development centers one after another. With the wide application of computer technology and power electronics technology, variable frequency variable voltage speed regulation and serial communication technology has been comprehensively popularized. Permanent magnet synchronous drag technology is also in bloom everywhere, China has become the elevator of the earliest market.
