There are two main types of wire rope fracture, one, overload fracture, that is, the wire rope by pulling force greater than the wire rope by the bearing force of the wire rope was pulled off. Second, the fatigue fracture, after the use of wire rope, wear and rust occurred first, wire rope diameter gradually reduced, in the wear of micro-cracks, micro-cracks extended to the wire fatigue fracture occurred, the fatigue fracture needs a longer period of time, usually several months or years, to prevent the wire rope from breaking suddenly. Firstly, the wire rope should not be overloaded during the use. Secondly, the wire rope should be inspected, including wear, broken wire and corrosion, the new rope should be replaced in time when it meets the national standard.
