Can't gantry.... garage is too small for that if I still want to park in it!!
I've kinda built my own engineered beam. I bought 3 2x8's, glued them together (liquid nails), and then screwed them together every 2-3 feet. I picked thru the stack to find the most knot free ones I could find. I'm going to wrap the area where the fall will be slung over the beam with some angle iron scrap I got from work (a cap if you will) to keep the chain that will go over the beam from eating into the wood. I talked to several guys at work (including the general contractor maintenance guy) and they all said this should suffice for my purposes.
Remember, the only thing this hoist will do is lift motors to get them off the stand and into the back of my truck. Simple, right?
