In the field of elevator technology, it is necessary to use the car to carry the load to realize the transportation of people or goods. Therefore, it is necessary to maintain a balance between the weight of the car and the weight of the payload to reduce energy consumption and motor power consumption. The balance of this weight is called counterweight. Through the counterweight, the required stress ratio between the car and the steel rope branch on the counterweight side can be maintained, and at the same time, a proper frictional force can be obtained between the steel rope and the rope groove of the steel rope drive wheel, so the counterweight has important meaning.

The counterweight device is located in the hoistway, and is connected to the car through the traction rope through the traction sheave. During the operation of the elevator, the counterweight device slides on the counterweight guide rail through the counterweight guide shoe to play a balancing role.
