    Unless you have it hanging around, aluminum would be way expensive. I'd think about wood for just occasional use. With steel on the top & bottom chord. Or a steel truss. How long? Portable, fixed? Enough headroom for a permanent gantry crane? Adjustable height? Offload a truck and lower it and roll into the shop? Lots of options. I don't there's a one-size-fits-all solution. If I had the space, I'd put in a permanent gantry plus a portable knock-down smaller one. Already have an engine hoist for small stuff.

    Yes! At the shop in the university, where I worked, my boss and I used some surplus aluminum I beam from an old surplus jet engine dolly to build the rails for our shop crane. We were in a basement with a concrete coffered ceiling so we made up steel U-brackets that we bolted through the coffers and hung the I-beams from. The I-beams were 3/8" thick 4"x4"x8" tall. We used a standard trolley and a Budget one ton electric hoist. It worked great! It was used mainly to move and set rotary tables like our 12" Troyke, milling vices, and an occasional machine. It had no trouble picking up one of our sheldon 10x48 lathes with the cabinet attached. That thing was a real "nad" saver.

    Just an idea.........

    If this is a space problem or you don't want it to be portable, maybe use the basic design only built stationary.........

    or maybe I'm crazy

    how about a mono rail system on each side of the ceiling that supports a crossbeam (from monorail to monorail) for your hoist. ive seen that done and its pretty simple and works quite well.

    its very tolerable to any mounting variables, just needs to be level. . . . but it takes a larger amount of headroom maybe. . . . .

    If what you want is something fairly light duty (~1,000 lbs or less) Harbor Freight has some trolleys that run on standard I-beam. I say light duty because I wouldn't want to trust a non-engineered crane system at anything close to the claimed ratings for the individual components. Also don't let the building inspector see your crane or he will make you take it down since it is not certified.

    That said, I built a jib crane in my shop and I don't know what I would do without it.

    Randolph Bulgin is one of our posters here and has written a book about his shop. His web site shows a shot or two in which his overhead crane is depicted (see the engraver table photo). His is what a lot of guys would love to have and maybe he will comment on its implementation, here,...although he does have a book to sell too
