Elevator operating system

Traction system: The main function of the traction system is to output and transmit power to make the elevator run. The traction system is mainly composed of traction machine, traction wire rope, guide wheel and anti-rope pulley.

Guide system: The main function of the guide system is to limit the freedom of movement of the car and the counterweight, so that the car and the counterweight can only move up and down along the guide rail. The guide system is mainly composed of guide rails, guide shoes and guide rail frames.

Car: The car is an elevator component that transports passengers and goods, and is the working part of the elevator. The car is composed of a car frame and a car body.

Door system: The main function of the door system is to seal the landing entrance and the car entrance. The door system is composed of car door, landing door, door opener and door lock device.

Weight balance system: The main function of the system is to relatively balance the weight of the car. During the operation of the elevator, it can keep the weight difference between the car and the counterweight within the limit and ensure the normal traction transmission of the elevator. The system is mainly composed of counterweight and weight compensation device.

Electric drive system: The function of the electric drive system is to provide power and implement elevator speed control. The electric drive system is composed of a traction motor, a power supply system, a speed feedback device, and a motor speed control device.

Electrical control system: The main function of the electrical control system is to manipulate and control the operation of the elevator. The electrical control system is mainly composed of operating device, position display device, control panel (cabinet), leveling device, layer selector, etc.

Safety protection system: ensure the safe use of the elevator and prevent all accidents that endanger personal safety. It consists of elevator speed governor, safety gear, rope clamp, buffer, safety touch plate, landing door lock, elevator safety window, elevator overload limiter, and limit switch device.
