The fatigue life of Tianjin Goldman Sachs Wuxi GM Wuxi Saifutian smooth elevator rope is far less than that of manganese phosphating coated elevator rope.

The fatigue test data show that the fatigue life of manganese phosphating coated elevator wire rope is 3 ~ 4 times that of smooth elevator wire rope with the same structure, and the fatigue life of smooth elevator wire rope produced by this manufacturer is far from that of manganese phosphating coated elevator wire rope. Manganese phosphating coating elevator wire rope is the most advanced technology in the field of wire rope manufacturing in the world at present. Its technology includes manganese phosphating coating, which is a surface treatment technology, which can greatly improve the wear resistance and corrosion resistance of wire rope surface. The surfaces of steel gears and worm gears are phosphatized by manganese series, which can be used for more than ten years without damage and wear.

Manganese phosphating coated elevator wire rope shall be implemented according to the national standard GB8903-2005. Many enterprises have purchased patents and obtained licenses, and produced a large number of manganese phosphating coated elevator wire ropes. for reference only
