Crane weight ascension is main task, the use of crane and the safety factor of the sling when ascension weight can not less than 6, check the broken wire, wear and corrosion of the steel wire rope, in a timely manner to the crane and add lubrication can prolong the service life of wire rope.

Commonly used phosphate coating wire rope, galvanized steel wire rope, wire rope, stainless steel wire or plastic coated wire rope used in atmospheric environment, patent technology production of manganese phosphate coating the longest service life of wire rope, heavy corrosion environment optimizing hot galvanizing - phosphate double coating wire rope.

Manganese phosphate coating steel wire rope, preferred or zinc manganese phosphating, compared with smooth steel wire rope production process, only increased the final wear-resisting phosphating process, steel wire wear resistance and corrosion resistance increased significantly, cold-drawn steel wire after phosphating without direct twist wire rope.

The fatigue test data show that the phosphating coating is smooth with structure wire rope fatigue life of wire rope about three times (laboratory) comparable conditions, is difficult to wear and corrosion reason outsized prolong the service life of wire rope.

The phosphorylation of manganese is the wear-resisting phosphating, which can solve the wear problems in the use of wire rope and improve the corrosion resistance.
