Extended data:

Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 65438+05 with the vertical line. There is also a step, in which the pedals are installed on the track and run continuously, which is usually called escalator or moving sidewalk.

Modern elevator is mainly composed of traction machine, guide rail, counterweight device and safety device (such as speed limiter, safety clamp and buffer, etc.). ), signal control system, car and hall door. These components are installed in the shaft and machine room of the building respectively. Usually, steel wire rope is used for friction transmission. The steel wire rope bypasses the traction sheave, and its two ends are respectively connected with the car and the counterweight. The motor drives the traction sheave to lift the car.
