The steel wire rope used in cranes is different from other types of steel wire ropes. During service, it passes through a relatively large number of pulleys, bears a relatively high probability of reverse bending, operates at a relatively fast speed, and bears relatively high impact loads. Wear and fatigue are its main forms of failure.
