I would be building a gantry or beam lift that could get to the machine and anything in my shop area first. Seems much more versatile
I have a gantry, but it's stored on the far side of the shop, with a lot of stuff between where I keep it and my Bridgeport!
I'm thinking the small hydraulic HF crane is light enough that it could be easily moved from the Bridgeport for hoisting vises and rotabs, to the lathe for hoisting chucks, to the trailer and to the truck for hoisting whatever, etc.
You'd just need to fabricate extra receiver plates, and bolt them up wherever you might need the crane.
Then you could just hand-carry the 50lb crane where needed, and drop it onto the post, instead of cleaning out the shop in order to roll the gantry over!
Partially disassemble it and the pieces weigh even less.
If the hydraulic cylinder fails, you can buy those anywhere.
That's a lot of versatility for $100!
