Can the patented technology of phosphating coated steel wire rope solve the problem of broken wires and strands of elevator steel wire rope?

Some elevator wire ropes have broken wires and strands in less than one year, which not only affects elevator safety, but also affects elevator operation. It is a long-standing problem for elevator companies and wire rope factories. If this problem is to be completely solved, elevator companies should adopt manganese phosphating coated elevator wire rope as soon as possible, because most of the early broken wires and strands of elevator wire rope are worn off, which can be proved by the wear marks at the fracture. Manganese phosphating film can improve the wear resistance and corrosion resistance of steel wire surface, thus delaying the occurrence of broken wires and strands and prolonging the service life.

The longest fatigue life is the main basis for judging whether the wire rope manufacturing technology is advanced or not. The fatigue life of wire rope can be verified and compared by fatigue test. A structural steel wire rope, such as 8 * 19s+NF- 12mm steel wire rope, was purchased from several manufacturers and tested on the same fatigue testing machine until the first strand broke. The wire rope with the longest fatigue life is the wire rope with the longest service life, and the comprehensive quality of the wire rope can be tested through fatigue test. The service life of wire rope is proportional to the fatigue life.

The patent technology of phosphating coated wire rope is the most advanced technology in the field of wire rope in the world at present. The fatigue life of manganese phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope with the same structure, which can be verified and compared through fatigue test. At present, there is no wire rope with the same structure whose fatigue life can exceed that of phosphating coated wire rope, so the patented technology of phosphating coated wire rope is the most advanced technology, at least in the field of wire rope in the world at present. Manganese phosphating film can improve the wear resistance and corrosion resistance of steel gear surface of automobile gearbox, and prolong the service life of steel wire rope by using this principle.

The patent technology of phosphating coated elevator wire rope is the only hope to completely solve the early broken wires and strands of elevator wire rope. Elevator enterprises should give priority to innovative technology to provide better experience for elevator users and improve market competitiveness.
