Rather then clutter up/go OT on the hydraulic crimper thread.

Here are some examples of how NOT to terminate a steel cable. The most frightening thing about these photos are that they are of OFFICIAL rescue trucks. IF you see winch cables like these being deployed get out of the way, preferably a long way and be ready to call the ambulances if not hearse!

Whats wrong with this? No thimble and a home made thimble with no guarantee that the loop is strong enough. Also wire is twisted in the loop!

Whats wrong with this? No thimble, only two dog grips and wrongly spaced

A good ferrule but whats wrong? No thimble



Now have criticised all three of these terminations but the common one was no thimble. Why is that bad? You put a large load on a wide loop going around a bar say 1-2 diameters of the wire then it is bent so that the steel wire will be deformed forming a 'birds nest' This will result in things like galvanisation cracking, crushing and over stressing of the wire.

Now if your winch cable does not have a thimble in. (YES I know some winch manufacturers supply cables like this) take the cable off and get it terminated correctly. Your local chain/lifting specialist and they will do it for the cost of a few beers.
