[0002] An elevator is a vertical lift powered by an electric motor and equipped with a box-shaped cabin. It is used to carry people or goods in multi-story buildings. Modern elevators are mainly composed of traction machines, guide rails, counterweight devices, safety devices, signal control systems, cars and hall doors, etc. These parts are installed in the shaft and machine room of the building respectively. Wire rope friction transmission is usually used. The wire rope is passed around the traction wheel, and the two ends are respectively connected to the car and the counterweight. Elevators require safety and reliability, high transportation efficiency, accurate leveling and comfortable riding. Elevators often have some faults during use. If these faults are not maintained and repaired in time, the elevator will be dangerous during long-term use.
