I've been asked a lot about building a gantry crane, and the discussion usually ends up with the enquirer buying a 1 or 2 ton Princess Auto gantry crane. The reason is that there hasn't been a much better option that is cost effective, easy to build but offers something that PA doesn't: portability.
Once you build the PA crane, that's kind of *it*... It is intended to stay in the shop or moved in one piece. I built mine to be transported and assembled in situ, but mine takes special equipment to erect that is also hard to transport... (mine is a 5 ton capacity, so everything is very heavy)
THE SOLUTION
This guy has built a very nice gantry that can be transported in a small car with a roof rack, straddle a trailer, and be erected by one guy in 10 minutes - without tools. Def an option for a guy with the tools and time to make one. and quite a bit cheaper than a PA crane. He sells plans for about 2 euros, and it is a great starting point if you are designing your own.
Here's part 1:
