I just finished building a nice small rolling gantry crane for the shop. Primary use will be for handling machine accessories (V-heads for horizontal mill, dividing head, shaper & mill vices etc) loading work on and off of machines and other light-duty material handling. I'll be moving hundreds of pounds with this, not thousands so a while ago i bought a nice, compact 1/2 ton spur gear chain hoist of japanese manufacture off of cragslist. This is the perfect size for my needs as it is fairly compact and doesn't have a big wad of chain like my 2 & 3 ton units.
Anyway, I bought it from a guy selling off stuff from an estate sale and paid something like $30 or 40 for it. Well i just got around to hanging it off of the crane and when i tried to operate it, the chain would jam in the "capstan-like thing" over one section of chain. After a bit of disassembly and inspection, it's readily apparent the unit had been overloaded at some point in its life. Links in the effected section of chain (all the way to the hook) do not move freely against each other and have stretched almost an 1/8 of an inch. I considered buying a new length of chain for it but after some consideration, i'm just going to scrap it. The body of the chain hoist may be perfectly fine, or there may be a crack just waiting to propagate while under load (even my small loads) and for $40 bucks, i'm not willing to take a chance. Despite a minor disappointment, it's good to know that these things bend and don't break.
