    I can't do any fabricating as I don't have one of the main tools for fabricating, a welder. However, I do have a grinder. I think my best bet is to grind the hoist's hanging brackets to fit through the trolley swing rings.

    I ordered the 80/20 parts direct from 80/20. I know, I know, they are expensive but in the end I'll have a custom sized gantry/crane to fit the space I have in my small garage.

      Get two pieces of decent sized angle iron and replace the bracket on top of the hoist with them, then use flat plate to link from the large through bolts in the dollies down to the angle irons. Drill holes where necessary and use appropriate sized bolts.

        One thing to think about is the fatigue life of the aluminum extrusions.
        If you move any significant weight it will fatigue, and it will eventually crack.

          Arcane...Thank you for the reply. I've attached another screenshot. This may be close to what you are talking about.

            eric_h...Thank you for the reply. My design has the 80/20 heavy aluminum 3030-S buttressed from the feet to the legs and from the legs to the I-beam. I'll keep an ear and an eye out for any type of fatiguing or cracking.

              One of the issues I may run into is that I have the I-beam sitting on a long piece of 1530-S between the legs that's 1.5 inches thick. Although this 1530-S may add a little support, I was using it more for the I-beam to sit on while I use 80/20 plates on the sides of the legs at the top which I can raise up enough over top of the legs, and the 1530-S, to create a cradle for the I-beam to sit in as I didn't have a way to connect the I-beam to the tops of the legs. I know, clear as mud.

              What may happen is when the trolley is attached to the I-beam, the trolley's swing ring may hit the bottom of the 1530-S aluminum and not be able to travel along the I-beam. The trolley may not even fit. I'm not sure that I can find a trolley that is just a smidge taller to account for the swing ring not touching the bottom of the 1530-S. Without having a trolley at present, I can't take any measurements to see.

                Yes, very close to what I was envisioning. If the one leg on the angle iron is long enough it eliminates the need for separate link.

                  To answer one of your original questions, the way to lift up a beam is with a Genie SuperLift. Your local tool rental place will probably have them. I just rented one to put mine back up. It was $55, about what I'd expect to pay for an engine hoist.

                  Here's a shot:



                  The SuperLift is like a tall light duty hand-cranked forklift except you can't move it with a load on. This particular one can lift 600 pounds 18 feet in the air.

                      Just like aircraft hopefully get replaced , before service life is exceeded..
