rwm, you acted so fast that I missed this entire thread while I was away on holidays, and now you have it...
So even being late to the thread I thought I'd mention a thing or 2... Our HF 'princess auto' had 1 and 2 ton gantry cranes for sale here, but when I looked at them and turned a 'engineer's eye' to them the seemed to be very seriously overrated. I might trust the 2 ton to lift a 750 lb load, but not if there was anything out of level with the location of the crane....
So for the price I made my own, learning a ton (!!) of stuff while doing it. I paid a little more than the price of the 2 ton without a trolley, but have a crane that will easily handle more than I'd ever lift.
I sent my drawings and pictures to a relative who runs a crane building/design firm, and he says that my rated capacity should be about 4 tons (so I overbuilt it a little)....
so my next project is to build a trolley: my main beam is 4" X 8" .188 wall tubing, as no commercial trollies will fit it.
Here it is hoisting my 2000 lb surface grinder :
