Double Boom Has Chain-Drive Sprocket

Double Boom Has Chain-Drive Sprocket FARM SHOP Tools 20-4-31 Here's one of the most useful and innovative overhead shop booms we've ever seen. David Buss, Clayton, Ill., built the over-head boom using a big 18-in. heavy I-beam. One end rolls back and forth on a heavy-duty trolly with a heavy-duty up-right post. The other end is hinged. The boom has two unique features. The frame of the boom is so strong Buss mounted a second boom on one of the posts. Set at about 8 ft. off the ground, it swings 180? and extends out about 10 ft. It's ideal for smaller lifting jobs. For ex-ample, you could use it to lift off the cylinder head on an engine and swing it out of the way, and then lift the engine with the main hoist. The other feature that makes the over-head boom handy is that the hoist hangs from a roller with a large sprocket mounted on one end. A loose piece of roller chain hangs from the sprocket. When Buss has a heavy load on the hoist and needs to move it a short distance, he just reaches up and turns the chain by hand, easily "walking" the load into position as needed.
