Product Details

Driving principle:


The traction machine is located at the top of the hoistway, and the traction wire rope/steel belt is connected to the car and the counterweight by the traction sheave. A guide wheel is placed on the traction machine so that the car and the counterweight do not collide in normal operation in the hoistway. The rotation of the motor drives the traction sheave, and the drive wire/steel belt drives the car to operate relative to the counterweight.
