Phosphating coated steel wire rope is a patented technology in China in recent years. Manganese series or zinc-manganese series phosphating film belongs to wear-resistant phosphating, which can greatly improve the wear resistance and corrosion resistance of steel wire surface. The steel wire rope directly twisted with phosphating steel wire is not easy to wear and rust, and its fatigue life is 3-4 times that of smooth steel wire rope with the same structure. The service life of wire rope is directly proportional to its fatigue life.
Anti-rotation steel wire rope is a kind of multi-layer strand steel wire rope, and the inner and outer strands are twisted in opposite directions, thus offsetting the torsional residual stress. This kind of wire rope is not easy to rotate, which can prevent the wire rope from intertwining, and is especially suitable for tower cranes. Its main structure is 35 * 7 or 19 * 7, etc. Wire ropes with other structures such as 6 * 36WS can be purchased to be used together with left-handed and right-handed wire ropes to achieve the purpose of anti-rotation.
The manufacturer has produced phosphate-coated multi-strand resistance rotating steel wire rope, which fully meets the national standard GB89 18-2006. Although the price is higher than that of smooth steel wire rope, the daily use cost is only about 40% of that of smooth steel wire rope because of its long service life. Phosphate coated wire rope is the most advanced technology in the field of wire rope in the world, and smooth wire rope will be eliminated. for reference only
