Air-Powered Shop Hoist FARM SHOP Tools 28-1-39 "It's lightweight and much easier to use than hydraulic lifts and can be built a lot cheaper," says Bruce Graham, Tyler, Texas, about his air-powered shop hoist.
A pair of air shocks are used to move the lift arm up and down. Air pressure is supplied by an on-board air compressor equipped with an electrical solenoid valve. The compressor motor runs off a battery that mounts on the frame. A non-powered hydraulic cylinder is used to lock the load into any position. A battery gauge and air pressure gauge mount just above the motor.
"I've used this unit in my shop for more than eight years and really like it," says Graham. "I got the idea after the engine in my friend's 4-WD pickup developed a valve train problem and we had to remove the cylinder heads. We put it together for that job and found it was a lot easier to use than a conventional hoist."
The hoist can lift up to 150 lbs.
