elevator compensation chains /keep balance

During the operation of the traction elevator, the length of the wire rope on the car side and counterweight side is constantly changing, which causes the change of the weight of the wire rope on both sides of the traction wheel. When the car is located in the lowest level station, the weight of the wire rope mostly acts on the car side: when the car is located in the highest level station, the weight of the wire rope mostly acts on the counterweight side. This kind of change has little influence on the operation performance of elevator when the elevator lifting height is not big, but when the lifting exceeds a certain height. It will seriously affect the stability of elevator operation and endanger the safety of passengers.

For this reason. when the elevator lifting height exceeds a certain height. it is necessary to set up components with certain weight to balance the weight change caused by the height change, which is the elevator balance compensation chain.
