    Is the wire rope of the elevator broken?

    For wire rope elevators used in elevators, the state has special regulations and requirements. The configuration of the wire rope is not only to bear the elevator car and the rated load, but also considers the magnitude of the traction force. Therefore, the tensile strength of the wire rope is much larger than the load capacity of the elevator. Their safety factors are all above 12, and the general elevators are all With more than four wire ropes, the elevator rope will not break. read more
