The traction elevator has a car running between at least two rows of rigid rails with a vertical or inclined angle of less than 15°. The car size and structure are convenient for passengers to enter and exit, and serve a fixed lifting device on a prescribed floor.

The elevator traction machine is the power equipment of the elevator, also known as the elevator main engine. The function is to transport and transmit power to operate the elevator. It consists of an electric motor, a brake, a coupling, a reduction gear box, a traction sheave, a frame and a guide wheel, and an auxiliary wheel hand wheel.China escalator company

The guide wheels are typically mounted on a load-bearing beam under a frame or frame. Some of the handwheels are fixed on the motor shaft, and are usually hung on the nearby wall, and then placed on the motor shaft when in use.
The drag-type elevator traction drive relationship, the motor installed in the machine room and the reduction gear box, the brakes and the like constitute a traction machine, which is the power of the traction drive. The traction wire rope is connected to the car through one end of the traction sheave and the counterweight is connected at one end.

In order to make the car in the hoistway and the counterweight run independently along the guide rails in the hoistway, a guide wheel is placed on the traction machine to separate the two. The gravity of the car and the counterweight causes the traction wire to be pressed into the traction sheave to create friction.

In this way, the rotation of the motor drives the traction sheave to rotate, drives the wire rope, and drags the car and the counterweight to move relative to each other. That is, the car rises and the counterweight drops; the counterweight rises and the car descends. Thus, the car reciprocates up and down along the guide rails in the hoistway, and the elevator performs a vertical transport task.
