The internal structure of the various systems and their working principles, the elevator system includes a total of eight systems, namely traction system, guidance system, car, door system, weight balance system, traction system, control system, and safety protection system.Bed Elevator manufacturer introduces the working principle of elevators

1. 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 the traction wire rope, the guide wheel, and the anti-rope wheel.
2. Guiding 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.
3. 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.
4. Door system
   The main function of the door system is to seal the landing entrance and the car entrance; the door system consists of the car door, the landing door, the door opener, and the door lock device.
5. Weight balance system
   The main function of the system is to relatively balance the weight of the car. During the elevator work, the weight difference between the car and the counterweight can be kept within the limit to ensure the normal traction transmission of the elevator. The system is mainly composed of the counterweight and weight compensation device. composition.
6. 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 traction, power supply system, speed feedback device, motor speed control device, and so on.
7. 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 a control device, a position display device, a control panel (cabinet), a leveling device, and a layer selector.
8. Safety protection system
   Ensure the safe use of elevators and prevent accidents that endanger personal safety. It is composed of elevator monitoring, elevator floor indicators, speed limiters, safety gears, buffers, and terminal protection devices.
