1, the broken wire rope, in the use of violent impact led to the operation of wire rope overload, damage, local wear, or wire rope in a serious corrosion, fatigue, speeding, slipping in the case of one or several wire rope broken.
2, wire rope distortion, bending, wire rope pulled out from the rope method is not correct, or winding in the drum is not correct, fixed improperly lead to its distortion, bending.
3, lifting the process of relaxation caused by its damage, the frequent use of wire rope, the operation of the beam caused by wire rope bending at the rope, and lead to fatigue and fracture of steel wire.
4, wire rope damage in the lifting operation, in the lifting operation of the use of improper use of wire rope, causing its damage or fatigue fracture.
5, the wire rope twist distance from the elongation or shrink, because in the lifting operation of the wire rope is often overloaded, so that the wire rope twist by extrusion caused by elongation or shrink.
