It definitely needs annual inspection, and the wire rope needs regular inspection and maintenance. Metal and non-metal mine wire rope inspection specifications AQ2026-2010, refer to the GB/T29086-2012 national standard for safe use and maintenance of wire ropes for maintenance, and perform inspection and scrapping in accordance with the GB/T5972-2016 crane wire rope maintenance installation inspection scrap national standards.
Commonly used types of steel wire ropes include phosphate-coated steel wire ropes, galvanized steel wire ropes, stainless steel wire ropes or plastic-coated steel wire ropes. When used in an atmospheric environment, the manganese-based phosphating coated steel wire rope produced with patented technology has the longest service life. The manganese-based phosphating coating can greatly improve the wear resistance and corrosion resistance of the rope-making steel wire surface, and the phosphating-coated steel wire rope fatigue The service life is 3-4 times that of smooth steel wire rope, up to 5 times. With the research on wear-resistant phosphating liquid, there is the possibility of further improvement. According to the current market price of phosphate-coated steel wire rope, the average daily cost of phosphate-coated steel wire rope is only about 30% of that of smooth steel wire rope. Phosphate-coated steel wire rope is an upgraded product of smooth steel wire rope and is for reference only.
