  • Shop Gantry

    I built a small 6 ton shop gantry to help moving things around when needed and I was bored. The legs are adjustable on the beam. The beam was a drop from a construction job so it was free...

    Big John,

    Nice job on the gantry crane. I am thinking about building one myself. I already have most of the steel, just need the time and energy.

    Thanks for posting it.

        Very nice work! I'm planning to build a similar gantry, so your pictures are much-appreciated!

        A few questions, if you don't mind:

        1. Those are great looking casters — what make and size are they, and where did you get them?

        2. What size is your beam?

        3. Any chance you could post a close-up pic or two of how the beam is clamped/bolted to the uprights?

        Thanks for posting this!

            I got them from McMaster Carr. They are cast iron wheels designed for concrete and roll very easy even with a heavy load like the lathe hanging on it. Part number 2293T31, Desc Brute Caster With 5-1/4" X 7-1/4" Plate, Swivel, 6" X 3" Cast Iron Wheel, 3000# Capacity

            I can take care of 2 and 3 this afternoon.

                Nice looking gantry but a little short on stability. Best not to move a gantry crane while it's loaded. That's not a wise maneuver and certainly not the intended purpose. A small screw left on the floor could ruin your day. Lift the load with the gantry then put dollies under the load to move. Of course, you can drive without seat belts, grind without safety glasses, paint without a mask or whatever else you want. I'm just sayin'...

                  For some reason I would be a little afraid of that thing bending under a good load so that the ends bend away from the center outwards, as they are standing alone without horisontal support other than the small 45 degree piece at the top.
                  Amount of experience is in direct proportion to the value of broken equipment.

                    Looks good,should work fine up to the rated capacity.Moving stuff with a gantry is much safer if the load is secured to the gantry at the base to eliminate the pendulum effect.
                    I just need one more tool,just one!

                      Might be a bit of a stretch to make it to Germany in the AM...

                        It is extremely stable and safe, put your doubting Thomas away.

                          If I was pulling it with a forklift I might be worried but pushing it by hand... no worries it is very stable and no swinging at all.

                            Don't be afraid it is really very strong and rigid.
