Manganese phosphating coated elevator wire rope is the highest quality wire rope manufactured by the most advanced technology in the world.

Friction between the elevator wire rope and the traction sheave groove drives the elevator to move up and down, and the sheave groove and the wire rope are easy to wear, which will reduce the service life of the wire rope and the traction sheave and have a certain impact on the safe operation of the elevator. Wear will produce wear debris and increase the incidence of fatigue cracks. The failure reason of wire rope is fretting fatigue.

Phosphate coated elevator wire rope is a patented technology. The rope steel wire is treated with manganese or zinc-manganese phosphating coating, both of which are wear-resistant phosphating, which can greatly improve the wear resistance and corrosion resistance of the steel wire surface. The surface of steel gear of automobile gearbox is phosphatized by manganese series, which can ensure the gear to work normally for more than ten years. Manganese phosphating film makes phosphating film elevator wire rope super wear-resistant and effectively inhibits fretting wear. The fatigue life of phosphating coated elevator wire rope is 3-4 times that of smooth elevator wire rope, which can be verified by fatigue test. It has the longest fatigue life and the best anti-fatigue performance among steel wire ropes with the same structure. Fatigue life can indicate the technical level of wire rope manufacturing.

The patented technology of phosphating coated steel wire rope in China is the most advanced technology in the field of steel wire rope in the world at present, and its fatigue life has far exceeded that of imported steel wire rope, which is also used by famous foreign steel wire rope enterprises in China. All kinds of smooth wire ropes are being eliminated. Personal opinion, for reference only.
