Default Columbus Mckinnon chain hoist problem.

I picked up a really nice Columbus Mckinnon lever style aluminum chain hoist at the local pawn shop. The trouble is that with any load on it, it ratchets, but doesn't hold. The pawl is external, and clicks with authority. I'm going to tear into it when I get a minute, but I thought someone here might have some insight, and advice.... Thanks.

NOT mine, but just like this one... http://www.ebay.com/itm/ALCOA-1-1-2-...YAAOSwyQtVnwzK

In addition to it having the up and down selector on the handle, does it have a large knob with "free chain" and "operate" marked on it? The large knob should be where the handle meets the body.

Not that I can find. Just the toggle on the lever, and the pawl. I did notice that it's a Model B, if that means anything to anyone....

If I remember correctly, the B has dual clutch disc. Remove the two screws on the handle cover, should be a slotted nut with a cotter pin thru it. Adjusting instructions are on the inside of the cover you removed. See what happens.

THANKS, that's just the kind of thing I was hoping to hear.

I thought I'd done pretty well for $35 till I tried it out. I was sure that something of it's quality would be repairable though.

And make sure there is no oil anywhere near that clutch mechanism-on mine there is a little warning tag to that effect , put there for the millwrights to ignore..............

I see that type of chain hoist from time to time, but never really gave them much thought, always seemed like it was a special application thing because if mounted too high you could not reach the lever. So what am I missing? How are these used?

We used them a lot at the factory I used to work for. Most guys regarded them as safer than cable come alongs. They used them upside down too, so the handle was on the low end. You also don't have the cable spooling up on a drum causing "jumps" and "falls'.

I sold a chain heat treating system and other hardening systems to CM. A first rate company and I'd bet parts are available should the clean and adjust routine be inadequate. Get it right, as an overhead hoist is the last thing you want to fail. If it's no longer reliable, trash it.

Are you the guy with the plant on the river in Bay View? Always seemed like a mysterious 'throwback' operation as I passed it........

Nope not me. I stay out of bay view as the area inhabitants make my skin crawl.
