I've been forgetting to ask if there are any great ways to design a I-beam trolley for a winch. Awhile back we unloaded a machine and the chain slipped around a cast part and jarred the whole crane contraption I have in the shop. The light weight electric hoist trolley that wasn't in use jumped up and pivoted right off and came slamming down.
Anyhow, now I don't trust this thing and have to make one myself. Pictures would probably be enough to go on. I just come up with bearings on bolts or I could make pins, but unsure if I should mill up some sides and then weld up a channel and then weld the pins in place or what. Four wheels, or 6, and should they be slightly angled to match the tapered beam? The end of the beam doesn't have access.
Maybe I'm just hung up on the idea of being able to take it apart. Is that really necessary? Hmmm I guess it would be a bitch cutting the thing off if (?) I destroy it.
