I decided to build a beam clamp to lift slightly heavy or awkward loads using an I-Beam I have in the garage. I cut 1/4" plate material with plasma CNC, painted, and assembled it. The first test was today.
Before welding the clamp bar (the center link) and before paint
Welded and painted
Installed and ready for use. I had to cut drywall away to get to my beam. I easily lifted a ~150lb load today. It should be able to lift considerably more but I'm not looking find the limit.
