FEATURES

 

Modern elevators are mainly composed of traction machine (winch), guide rail, counterweight, safety device (such as speed limiter, safety gear and buffer, etc.), signal control system, car and hall door, etc. These parts are respectively installed in the shaft and engine room of the building. Generally, steel wire rope friction transmission is adopted. The wire rope goes around the traction wheel, and the two ends are respectively connected to the car and the counterweight. The motor drives the traction wheel to make the car lift. Elevators are required to be safe and reliable, high conveying efficiency, accurate leveling, and comfortable riding. The basic parameters of the elevator mainly include the rated load, the number of passengers, the rated speed, the size of the car's outline, and the type of hoistway.

 

Simple method of use (there are solutions below for emergencies):
