Patent of clean crown block

The wire rope is broken, seriously worn and coiled due to plastic deformation, so a new rope must be replaced immediately to prevent the wire rope from breaking suddenly. This potential safety hazard needs to be eliminated as soon as possible.

Commonly used steel wire ropes include phosphating coated steel wire rope, galvanized steel wire rope, stainless steel wire rope or plastic coated steel wire rope, which are used in atmospheric environment. Manganese phosphating coated steel wire rope produced by patented technology has the longest service life, and hot dip galvanized-phosphating double coated steel wire rope is preferred in heavy corrosive environment.

Phosphating coated steel wire rope produced by patented technology gives priority to manganese series or zinc-manganese series phosphating. Compared with the production process of smooth steel wire rope, it only adds the final wear-resistant phosphating process, which greatly improves the wear resistance and corrosion resistance of steel wire rope. Wire rope is directly twisted without cold drawing after phosphating. At present, the fatigue test data show that the fatigue life of phosphating coated steel wire rope is about 3-4 times that of smooth steel wire rope with the same structure (under comparable conditions in laboratory), and the highest is 4 times. With the research of wear-resistant phosphating formula, it is still possible to improve it greatly. Manganese phosphating is wear-resistant phosphating, which can solve the wear problem of wire rope in use, for reference only.
