Shenyang crane accessories Freight transport can not be separated from cranes. The crane can not be separated from the steel wire rope. The sudden breakage of the wire rope will cause serious accidents. Therefore, the selection of high quality wire ropes is very important. Shenyang crane accessories Domestic varieties of wire rope are as follows: 1. phosphating coating wire rope (Chinese patent), steel wire by manganese, zinc manganese system phosphating treatment, steel wire wear resistance and corrosion resistance jumped up, not easy to wear and corrosion, so that the fatigue life of wire rope is greatly improved, fatigue life is 3 times the same as that of structured smooth wire rope. Instead of galvanizing steel wire after galvanizing, the corrosion resistance can be tested by salt spray test. The service life is long, the unit use cost is lower, and the quality stability and reliability are better.
