The elevator is a complex set that contains a number of elevator parts and functions.

The main components of the elevator are: safety protection device, emergency rescue device, hoistway safety door and trap door, driving host, car, landing door and car door, electrical control device, etc. The elevator traction machine is the core component.


The elevator traction machine is the power equipment of the elevator, also known as the elevator host. The function is to transport and transfer power to make the elevator run. It is composed of electric motor, brake, coupling, reduction box, traction wheel, frame and guide wheel, and accessory disc car hand wheel.


The three major parts of the elevator (core components): the host, the door machine, and the control drive system.


1. Host: a good host is energy-saving, with low noise, long life, and basically no maintenance
