What is the difference between the amount of wire rope and the amount of wire that the electric gourd is equipped with
Galvanized steel wire rope, hot galvanizing and galvanizing Stainless steel wire, 304 or 316 stainless steel Apply plastic wire rope, wire rope foundation, outer coating polyethylene or polypropylene The polished wire rope will be completely eliminated by the phosphating coated wire rope.
China product steel rope 1.8 million tons first in the world, phosphating field of wire rope is the world's first inhibition of fretting fatigue service life by surface treatment (fatigue life) : Phosphating coating steel wire rope, steel wire by the department or zinc manganese phosphating, wire wear-resisting, corrosion rust resistance jump in an all-round way, life is about three times with smooth surface structure wire rope (note that drawing with zinc series phosphating and rope with wear resistant phosphating, although in tianjin, jiangsu and other places there have been several enterprise production, at present still supplies, in short supply)
Same tonnage, lifting weight, number of wire rope is different, perhaps because of the following reasons, the strength of the steel wire rope level is different, high strength steel wire rope, can use smaller diameter, just breaking force conform to the requirements, the diameter of the same case, the steel core wire rope breaking force greater than that of hemp core wire rope, on the other hand, may block number, pulley, showing a high number of cable force is small, can use small diameter wire rope.
