🙂 We didn’t want to leave expensive hydraulics at job-sites, so these are just inexpensive Harbor Freight Tools hand pump 3 Ton rams and they work on other equipment if needed. A bit slow with one guy walking back and forth to each side but it works however, with 2 guys it takes about 5 minutes to raise or lower i-beam and the boltd/pins are secured when at the height wanted so the hydraulic rams can them be removed if we wish.

The hand-pump hydraulics were inexpensive low-tech way for one guy to raise and lower the Hoist from the lowest position to the highest. The design allows for the Hoist to be unbolted and put on a trailer with a Skid Steer in about 30 minutes and transported to different job-sites for use on-site for weeks at a time … Pretty much need a skid steer to assemble it on site, but only takes two guys 🙂 Thank you for the nice comment 🙂 This is a link to the Gantry Crane Hoist Design we ended up making
