How to do the winter maintenance work of the plastic compensation chain, the elevator is divided into traction elevators and hydraulic elevators, and the traction elevators are commonly used on the market. Any of the traction elevators consists of the following basic components: car, traction wire rope, counterweight, and accompanying cable.
During the operation of the elevator, the length of the wire rope on the car side and the counterweight side is constantly changing, thereby causing a change in the weight of the wire rope on both sides of the traction sheave. When the car is at the lower station, the weight of the wire rope is mostly applied to the car side; when the car is at the landing, the weight of the wire rope is mostly applied to the counterweight side. This kind of change has little effect on the running performance of the elevator when the lift height is not large, but when the lift exceeds a certain height, it will seriously affect the stability of the elevator operation and endanger the safety of passengers.
For this reason, when the lifting height of the elevator exceeds a certain height, it is necessary to set a component with a certain weight to balance the weight change caused by the height change, which is the elevator balance compensation chain.
