It's probably relatively cheap low carbon steel "proof coil" or grade 30
chain. You'd want grade 80 or even stronger grade 100 high strength *alloy*
steel overhead lifting chain for overhead lifting, but it would be overkill
compared to even Grades 43 ("high test") and 70 ("transport") chain.

3/8" proof coil is only rated for about 2600 lbs, you'd need 5/8" proof coil
(almost 4 1/4 lbs/foot) or 3/8" grade 70 (just over 1.5 lbs/ft -- 37% the
weight of proof coil) for 6500 lbs!

For dragging logs, locking up ladders, motorcycles, etc. and what not proof
coil serves well enough. Grade 70 "Transport" chain is often used for
lashing things (machinry, cars, etc. down on flatbed trucks, etc.

I've been looking at chain lately (3/8") and I've noticed something that
so far, every hardware guy
says he's never seen before. On the box of chain, without exception, they
all say "DO NOT use for
lifting or any situation where a life could be endangered if the chain
fails.

Tell me if I'm wrong here, but what in the hell could a person use a 3/8"
chain for that wasn't
potentially dangerous. If the chain has a rating of 6,500 pounds and
breaks, someone is going to be
around!!!

Is this a case of lawyers being in charge of chain-making or is there
actually different chain that
is approved for lifting and all the stuff at H.D., Lowes, Ace is made for
something else... what I
don't know.

Any suggestions? :-)
