Elevator work

Traction rope ends were attached to the car and counterweight, wrapped in traction wheel and guide wheel, traction motor through reducer rotating speed rear wheel drive traction, traction rope by friction and traction sheave , to achieve the car and the counterweight lifting movement, to transport purposes. Fixed on the car guide shoe can be installed in the buildings along the hoistway wall fixing rail reciprocating movement at the car in operation to prevent skewed or swing. NC block brake on the motor work loose brakes, operate the elevator inverter in case of loss of power brake, stop the car and landing, and stand on the specified layer to maintain its quiescent state for personnel and cargo access. The car is carrying passengers or other load box member, the counterweight to balance the car load, reducing motor power. Compensation means for compensating movement of the traction rope tension and weight changes, so that the traction motor load stability, the car can be accurately docked. Electrical system to achieve the control of movement of the elevator, and complete layer selection, flat layer, speed, lighting work. Call system displays the car indicating the direction of movement at any time and location where the floor. Safety devices to ensure safe operation of the lift.
