What is the reason that the inner layer of the multi layer steel wire rope of 5t winch has been squashed several times?
The wire rope is wound on the reel winch or above will produce compressive stress, thus prone to deformation, using steel core wire rope, wire rope is not easy to deformation, hemp rope is very easy to be compressed, compressed steel wire rope must be immediately scrapped for new rope, prevent the occurrence of accidents, recommend the use of steel core wire rope such as 7*19W, or 8*19W+IWR
1. phosphating coating steel wire rope (patented technology), manganese or zinc wire by manganese phosphating, wire wear and corrosion rust resistance comprehensive jump, compound effect of phosphating film and grease, restrain the occurrence of fretting wear, fatigue life is the same structure of plain steel wire rope 3 times the left and right, can be verified by fatigue test the fatigue life (to do the fatigue test of the most credibility) is a replacement of wire rope, smooth upgrade, also be replaced after plating the first pull layer of thin zinc galvanized steel wire rope used (by salt-mist test or comparison of corrosion resistance).2. galvanized steel wire rope, including hot-dip galvanizing and electro galvanized two, in general, hot galvanized zinc layer thickness, zinc plated zinc thin3. stainless steel wire rope, 304 or 316 stainless steel based, anti-corrosion effect is very good, but expensive4. carbon coated steel wire rope, wire rope based on polyethylene, polypropylene or nylon outer coating5. smooth steel wire rope, the market demand fell sharply, will be fully replace phosphating coating steel wire rope.6. marine engineering mooring wire ropes, standards are under development, approval process
