The service life of wire rope is proportional to the fatigue life, and the longer the fatigue life, the longer the service life of wire rope. The fatigue life of elevator wire rope measured in laboratory is an important technical index to characterize its comprehensive quality. The longer the fatigue life, the higher the manufacturing quality level.
At present, the fatigue life of manganese phosphating coated elevator wire rope is the longest in the same structure, which is 3-4 times that of smooth elevator wire rope. Manganese phosphating is a wear-resistant coating. The phosphating film is firmly combined with steel wire, and the phosphating film is hard and very wear-resistant. At the same time, it can improve corrosion resistance and prevent corrosion, so it can effectively inhibit fretting fatigue and greatly improve the service life of steel wire rope.
Manganese phosphating coated elevator wire rope fully meets all technical requirements of national standard GB8903-2005, and is the most advanced manufacturing technology and the highest quality level in the wire rope industry in the world. for reference only
