New chain hoist ?

[TheToolman]

I just got this hoist that says ON the BIG chain wheel-
SCREW HOIST 1000 LBS CAPACITY D. ROUND & SON, CLEVELAND O. U.S.A.
It has 1 big wheel & it has 2 smaller ones that go in the same direction when you turn the big one. I need a picture or something to help me put new chain on this hoist. I have chain but no idea how to run it on the pullies
THANK YOU
Dan

Dan,
Can you post a photo of it? I have a 1/2 ton and a 1 ton, mine have cast into the frame " HOIST" but we call them "chain falls".. I'll compare yours with mine and see what we can come up with.. How long is this chain you have? I cant remember if there's 2 sheaves on top and 2 on bottom or only 1 on bottom.. Will check tomorrow if I can remember where they are!

Not trying to hijack your thread here, but figured I'd ask this while we're on the subject of chainfalls (or hoists).

I have a Yale & Towne 1&1/2-ton chainfalls that needs a new chain (it was left in a barn cellar for decades and the mechanism is fine -- it was up on a milk crate -- but the chain lay on the damp floor for too long and has rusted _way_ beyond the point where it is safe to use. You know, big flakes coming off -- that kind of rusted). Does this call for a special grade of chain, or can I use standard 3/8"-link chain? I've been eyeing the chain rack at the local supplier, but don't know if I should use "proof" links, or... ?

I probably won't be using it for stuff that weighs much more than half the rated capacity, but I'd like to have confidence in the tools I work with.

Thanks for any information you are able to provide.

HERE IS a couple pictures of what I need the chain routing for

TheToolman,

If you were to hang the hoist by the hook on it, the chain would be draped over the two rollers, with the links fitting into the cast-in slots/ovals. The hook would hang below the hoist, secured to both loose ends of the chain. The hand wheel would have a smaller chain (or maybe a rope, depending on how the wheel is designed) on it that was about the same length as the lifting chain.

Considering the size of the hoist, I think that a 5' to 7' chain would be plenty.

Bruce B. -- the chain used for a hoist is a tempered chain. It has slightly different dimensions for the links and is definitely a special alloy that is tempered. Real hoist chain will support several times the load that ordinary chain of about the same dimensions will.
Please DO NOT try to use ordinary chain in the hoist.
