I ordered a few Crosby items from a rigging shop to repasr some old steel line to use as a extention. Looking at the rigging sights web page i saw a few things i would mind having. I understand most of our off road gear is raited at the weight it will fail. Most rigging gear usses WLL. From what i see most things fail raiting are about 4-5 times there WLL but some are as low as 3X there WLL. Am i right so far? Looking at my 3/4 shackles i see a WLL of 4 3/4 tons, about 9000 pounds. I never really hear about shackles failing, do you? It made me think that in general if i stick with a min WLL from a rigging shop of around 9000-10,000 i should be pretty good. Just as info i have a M12,000 with 3/8 amsteel on it. I think my lune has a fail point of 19,000 or so. Much less than a WLL of 10,000. Is my logic bad or about right? I know there is no 100% fool proof with vehicle recovery. Things go wrong and fail and you need to always be in a safe position if somthing brakes. But am i about right with a WLL number?
