The importance of wire ropes in cranes

The importance of wire ropes is self-evident. Since it is a component with high force and wear frequency, it is necessary to pay special attention to the following points when selecting and using the wire rope.

The importance of wire ropes in cranes

1. Where the wire rope is easily affected

First, after the pulley is bypassed, the contact area between the wire rope and the pulley and the sliding between them accelerate the wear of the wire rope, the contact stress becomes large, and the possibility that the wire rope breaks is greater.

Second, if all other conditions are the same, the lower the safety factor of the wire rope used, the shorter the time it will be used.

2, The wire rope needs attention

The force of the wire rope is very complicated, and it will produce many forms, such as tensile stress, extrusion stress, residual stress, etc., when the wire rope bypasses the pulley, it will generate large alternating stress, because of the long time wire There is wear and tear, which causes the wire rope to break, so this requires attention.
