The elevator has a car and a counterweight, which are connected by a wire rope. The wire rope is driven by the driving device (traction machine) to make the elevator car and the counterweight move up and down on the inner rail of the elevator.
The steel wire rope for elevators is special for elevators, and the country has special regulations and requirements. The configuration of the wire rope is not only to bear the elevator car and rated load, but also considers the size of the traction force. Therefore, the tensile strength of the wire rope is much greater than the load of the elevator, and their safety factors are all above 12. Equipped with more than four wire ropes, the elevator wire rope will not be broken once.
