For wire rope users, the longer the service life, the higher the quality and the longer the service life, the more advanced the manufacturing technology. Service life can only be recorded and cannot be accurately measured. The fatigue life of steel wire rope can be accurately measured in the laboratory. The longer the fatigue life, the longer the service life. They are in direct proportion. Manganese phosphating film is a wear-resistant protective coating, which can prevent fretting wear and oxidation corrosion of steel wire, thus prolonging its service life. The fatigue life of manganese phosphating coated elevator wire rope is three to four times that of smooth elevator wire rope. Therefore, manganese phosphating coated elevator wire rope is an advanced technology, and smooth elevator wire rope is a product that is being eliminated. Manganese phosphating coated steel wire rope is an invention patent of China, and its fatigue life has greatly exceeded that of imported steel wire rope. The phosphating film weight of manganese phosphating coated steel wire rope is within 3-60g/m2, so it can be negotiated with the manufacturer to adopt a larger phosphating film weight, such as 15-30g/m2, which is beneficial to improve the service life.
