Main Parameters:
The main parameters refer to the rated load and rated speed.
Rated load Q (kg) is the load on which the elevator is manufactured or the load on which the seller guarantees normal operation.

Working Principle:
The traction rope is connected to the car and counterweight at both ends respectively, and is wound on the traction sheave and guide sheave; the traction motor drives the traction sheave to rotate after speed change through the speed reducer and realizes the lifting and lowering movement of the car and counterweight to achieve the purpose of transportation through the traction force generated by friction between the traction rope and the traction sheave.
