[AT] OT - Question about chain

[charlie hill]

You are right Al,  a chain will fly when it breaks. It won't throw a
stump at your truck but the broken end of it, un-impeded by a load
will do a lot of damage.  I've seen it but luckily haven't felt it.
Cable is even worse!

You'd be surprised.  Like I said I haven't seen it myself, but there has 
been many-a chain hooked behind a big tractor to pull another tractor, 
truck, combine, etc. out of the mud that has snapped and rocketed through 
the back glass of the pulling tractor's cab.  I know of a guy that got 
banged up pretty badly because of that once.

With that much power, all kinds of crazy stuff can happen when the chain, 
cable, strap, etc. comes tight. It comes down to how much risk you want to 
accept and how bad you want the object pulled out.
