Question on Mounting Electric Hoist

yes sir

MyOldTools, I see you added the anti-tilt mod to your trolley (Pic#3) - pretty much mandatory IMO, I still gotta do that one to BOTH my cranes... Steve

It's very important to account for the offset load. In the picture you reference, almost all of the downward load is concentrated on just one side.

I have a HF hoist at work that I modified in a different way. I welded a D bracket on top that holds a clevis that we grab with a hook, so the hoist is free to swing. The bracket is welded on directly above the spool. Allowing it to swing keeps the forces all in a single line.

The issue with doing this is that the hoist is out of balance like this, with the motor overhanging one side. So what I did was weld on a stick of 1" all-thread sticking out opposite the motor. On that rod, I've got a cast iron counterweight that I can adjust with a pair of nuts to balance out the motor. Now, it hangs straight and level, no matter what the load. However, the width of the cable spool is a slight issue.

At home, I have a pneumatic chain hoist. Since the chain always falls in the same line down from the sheave, chain hoists don't have these issues. Really, chain is superior to cable for this sort of lifting in so many ways.

Yeah, I'm thinking about mounting the hoist lengthwise to the beam, so far that's just a brain fart til I get a chance to "smell" it ... Steve
