? Crane users need high-quality steel wire rope, which should be a steel wire rope with a long service life and a high degree of stability and reliability. The main reason for the failure of the steel wire rope used in the atmospheric environment is fretting fatigue. At present, the world's steel wire rope field takes preventive measures against fretting fatigue. The phosphating coated steel wire is produced by technology, and the steel wire is treated with manganese phosphating or zinc manganese, and the wear resistance of the steel wire surface is improved. Fatigue life is three times that of the same structure smooth steel wire rope (comparable conditions in the laboratory), can be verified by fatigue test, if you have a fatigue testing machine to do their own comparison test, such a test junction is credible, the service life of the steel wire rope is proportional to the fatigue life, and the service life is extended in proportion to the fatigue life.
