Three Kinds Of Brakes Of The China Elevator

China Elevator from the drive principle to the structure and vertical elevators are very different, and its working principle is a chain of the conveyor belt, is a mandatory drive, so once the blockage may cause damage to the equipment. The main features of the work are: open type, so the gap involved in foreign body is caused by personal injury and equipment damage the main reason.

There are three types of actuators for the China escalator: working brakes, auxiliary brakes, emergency brakes. Work brakes are mainly used for escalators to stop running, providing braking force, installed in the reducer on the high-speed shaft. There are two general forms. Belt brakes and block brakes. The working brake may be in an emergency brake when the escalator is in operation. The deceleration during emergency braking is related to the safety of the passengers. Therefore, the deceleration of the action must be required, the size of the deceleration and the size of the escalator run. While the size of the deceleration is reflected in the stop and stop the distance.

The auxiliary brakes have the same effect as the operating brakes and act as an insurance when the escalator is stopped, especially when the auxiliary brake is acting at full load. Additional brakes are used to stop the drive shaft when the drive chain is suddenly broken, so the additional brakes should be mounted on the drive shaft and are normally mounted on the drive sprocket. The additional brakes must be mechanical.

China escalators are equipped with large-scale public buildings, such as large shopping malls, which have the characteristics of such flow. Of course, the slow pace of escalator exercise is a drawback. Second, the escalator for those who are frail and carry large items are also inconvenient, so in public buildings, in the installation of escalators at the same time, still need to consider the installation of elevators or general staircase, as an auxiliary vertical transport.
