Small crane wire rope breaking reasons

Laizhou Lutong Plastics Co.,Ltd | Updated: Aug 01, 2016

Crane wire rope failure process under normal use and is characterized by wire rope winding system, friction pulleys and reels and repeated bending and straightening and squeeze, in the case of busy work, this phenomenon is more serious. Small crane after a certain time, the outer wire due to bending fatigue fracture and wear and gradually. With the increasing number of broken wires, no broken wires under tension, the greater, more powerful fatigue and wear, broken wire speed. When the number of broken wires up to a certain limit will cause a complete break.

Small crane wire rope breaking overloading was the main reason. New steel wire rope is used under normal conditions does not occur all of a sudden the whole root fracture. Only in the load case of the ultimate strength of the bear, occurs all of a sudden fracture.
