What is the reason for the fact that the inside of the 5t winch is crushed for dozens of times
Wire rope winding on reel or winch can produce a compressive stress, which are prone to flattening deformation, use the steel core wire rope, wire rope is not easy to deformation, hemp core wire rope is very easy to get squashed flat wire rope must be immediately discarded in new ropes, prevent accident, it is recommended to use steel core wire rope, such as 7 or 8 * * 19 w structure 19 w + IWR
1. The phosphating coating wire rope (patent technology), steel wire by the department or zinc manganese phosphating, wire wear-resisting, corrosion rust resistance comprehensive jumped, phosphating film with the composite effect of the grease, restrain the micro wear and fatigue life is about three times, with smooth surface structure wire rope fatigue life by fatigue test (personally do fatigue test of the most credibility), is an upgraded version of smooth steel wire rope, and alternative galvanized steel wire rope using zinc plating before they pull thin layer (through salt spray test test or compare the corrosion resistant ability). Galvanized steel wire rope, including hot galvanizing and electrogalvanizing, generally, hot galvanized zinc layer thick, galvanizing zinc layer thin Stainless steel wire rope, with 304 or 316 stainless steel, is excellent for corrosion protection but is expensive Coating plastic wire rope, carbon steel wire rope foundation, outer coating polyethylene, polypropylene or nylon Smooth steel wire rope, a dramatic reduction in market demand will be completely replaced by a coating of phosphorised coated wire. Marine engineering mooring wire ropes, relevant standards are in the process of making approval
In the atmosphere, it is used in the use of the preferential phosphating coating wire rope, the heavy corrosive environment and the selective hot galvanizing of the environment, the steel wire rope of the double coating, the priority of the sea water. When purchasing, please note that in purchase invoice must indicate the name of wire rope, such as phosphating coating or 316 stainless steel wire rope, wire rope to protect their legitimate rights and interests, in addition, patent products in wire rope spray on the outer packing has the patent number, only supplies the reference
