If you were closer I have a knee crane and 1 ton hoist I would part with. It is the kind that bolts to a I beam and can pivot 180 degrees.

Speedy:)

Well I am driving out to MN for Thanksgiving. Would it fit in the front of the 86?:D


I may be purchasing this hoist which comes with a gantry to attach to the boom. Currently has a 12 foot chain. Is this something where I can just source a longer chain, 25 feet? Casters are on the way.

You cut the chain, get split links and more chain from a good hardware source, and lengthen the chain.

McMaster-Carr will have it, but shipping chain is expensive... you can find it locally

Thanks Tim, have a local hardware store down the street. this is coming together!

Next question. This thing is 230V 3 phase. Not a problem for where I want to hoist initially, any problem with making a 50 foot extension cord so I can use it out front? What spec wire would I get?

You'd need to identify the amps/watts, but the bigger the better. Your limit in terms of pulling enough amps will be at that 3 prong plug.

Be careful what splice links you buy, they have to fit through the gears.

Couple of things to consider. The chain on a overhead lift is nowhere close to what you will find at the local (China) hardware store and anything less than welded links would be a cause for concern.

Additionally if this is a business, I believe that floor has to be load rated by a PE. If my memory serves me well, look at OSHA CFR 1910 I think. I believe it is referenced in the General Industry standard.

If you have to get a crane, I believe OSHAs new crane standard goes into effect to some degree on the 8th.

Wire-Gauge Ampacity - Transwiki
These are the minimal wire guages vs amps/watts.

You should also consider the rated specs of the motor at full load, and the complete chain of electrical pathway from transformer, through building circuit breakers, through connections, through tool.....
Nothing like getting stuck with a rental crane for a couple of days.
