There are two main types of wire rope breakage, one, overload fracture, that is, the tension of the wire rope is greater than the bearing force of the wire rope is pulled off. Second, fatigue fracture, after the use of the wire rope, the first wear and rust occur, the diameter of the wire rope gradually decreases, micro-cracks occur at the wear, micro-cracks expand to the steel wire fatigue fracture, fatigue fracture takes a long time generally several months or years

To prevent the sudden break of the wire rope, first, the use of the process can not be overloaded, second, the wire rope inspection, including wear and tear and rust, in line with national standards, to replace the new rope in time.
