Subframe Supports Shop Hoist
The jib-style shop hoist in Roger Gutschmidt’s shop has handled heavy lifting for 38 years, thanks in part to the subframe embedded in concrete. It was only the first of many he has built for neighbors and, more recently, for his brother.
“I really like my overhead hoist for lifting motors out or other objects from a pickup bed,” says Gutschmidt. “I didn’t build it as strong as I should have, but it has done its job since 1988.”
When he began receiving requests from others to build shop hoists, he had an engineer review his plans. While his subframe remained essentially unchanged, the engineer recommended a stronger vertical beam. In the years since, he estimates he’s made around 30 subframes for hoists.
“The subframe is a combination of rebar and vertical bolts that extend through a 1/2-in. thick skeleton top steel plate,” says Gutschmidt. “To install it, we dig a 5-ft. deep, 4-ft. dia. hole and place the subframe with the skeleton plate below the surface. The skeleton plate ensures we can fill the hole to the top with concrete without concern for a void forming under the plate.”
A second steel plate, set over the protruding bolts, serves as the base for the vertical post and sandwiches the skeleton plate.
When his brother installed his shop hoist, he used 1/2-in. thick, 15-in. square steel tubing for the vertical leg. A 20-ft. I-beam jib pivots in a bracket on the tubing. A tie-rod support to the jib extends to a similar pivoting bracket at the top of the leg.
“I welded the brackets and painted everything,” says Gutschmidt. “My brother and nephew installed it. It’s incredibly strong. It could lift 4 tons 20 ft. out on the jib.”
The leg serves double duty in the shop. Ends are sealed with 1/2-in. thick steel plates. Air couplings were installed in the tubing.
“They use the leg as a pressure tank for their air compressor,” says Gutschmidt.
