Does the tensioning winch wire rope used in coal mine belt conveyors require annual inspection?

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.
