Commonly used wire ropes include phosphating coated wire ropes, galvanized wire ropes, stainless steel wire ropes or plastic coated wire ropes. Crane users need high-quality steel wire rope, which should have long service life, high stability and reliability. The failure of steel wire rope used in atmospheric environment is mainly caused by fretting wear, fatigue and corrosion. At present, the first preventive measure against fretting fatigue in the field of steel wire rope in the world is phosphating coated steel wire rope produced by patented technology. After manganese phosphating or zinc-manganese treatment, the wear resistance and corrosion resistance of steel wire are improved in an all-round way. It is not easy to wear and corrode, and the fatigue life of phosphating coated steel wire rope is three times that of smooth steel wire rope with the same structure (under comparable conditions in laboratory), which can be verified by fatigue test. If you have your own fatigue testing machine, you can do a comparative test yourself. This test result is the most credible. The service life of wire rope is proportional to the fatigue life, and the service life will also be extended in proportion.
Although the price of manganese phosphating coated steel wire rope is higher than that of smooth steel wire rope, the average daily use cost is only 40-55% of that of smooth steel wire rope because of its long service life. Phosphating coated steel wire rope is produced by patented technology and has been legally produced by many enterprises. It's hard to get it at present because the demand exceeds the supply. Please note that the name of wire rope must be indicated on the purchase invoice, such as phosphating coated wire rope. Prevent illegal enterprises from infringing their legitimate rights and interests with fake and shoddy products. In addition, patented products will generally be marked with the patent number on the outer package of steel wire rope, and the warranty should have the main technical indicators, such as the type and weight of phosphating film (phosphating film has an important impact on the service life of steel wire rope, such as wear resistance and corrosion resistance, etc.), for reference only.
