China Passenger Elevator is mainly composed of traction rope, car phase, counterweight, guide wheel, motor, reducer, brake, etc. The counterweight and the car are connected by the traction rope and wound on the guide sheave and the traction sheave respectively. The motor drives the traction sheave to rotate through the speed reducer. The lifting and lowering movement of the car to achieve the purpose of transportation.

The guide shoe on the car realizes the reciprocating lifting movement of the car according to the fixed guide rail installed on the wall of the hoistway, so as to avoid the situation that the car swings or deflects during the lifting movement.

The brake releases the brake when the motor is working to make the elevator run, brakes when the elevator loses power, stops the lift of the car, and maintains a static state at the designated floor to ensure the normal entry of people and goods. As a boxcar that carries passengers, it needs to use a counterweight to balance the load and reduce the power of the motor. The compensation device of the elevator ensures the stability of the motor load by compensating for the weight and tension changes in the movement of the traction rope and ensuring that the car can stop accurately.
