Overhead Crane Pivots 360 Degrees
The crane is located in the center of Mariner’s shop, which has a pair of big doors spaced 30 ft. apart on one side and overhead storage shelves on the other side. Mariner can pivot the crane out to the center of both doors to unload trailers or trucks parked inside.
“To move the crane around I just pull on the electric hoist cable and swing it in either direction. It rotates very easily with a big load. Even my 8-year-old granddaughter can handle it,” says Mariner. “It can lift up to 1,600 lbs.
“I didn’t want a single I-beam equipped with manual chain hoists, because I didn’t want any limitations when creative lifting problems arose. So when I decided to build a new shop, I built the lift system first and then built the shop around it.”
The crane is supported by a 5-in. dia. steel pipe, with its bottom welded shut, that goes 4 ft. deep into the ground and is encased in cement. Mariner put nine 1 1/4-in. dia. steel balls inside the pipe and also a half gal. of 90-weight used transmission oil. He then dropped a 4-in. dia. steel pipe, with its bottom welded shut, inside the 5-in. pipe. The last step was to pour in the concrete.
“The steel balls act like bearings, and the transmission oil keeps them lubricated,” says Mariner.
“It really comes in handy. I often use it to lift my zero-turn riding mower so I can change the blades or the oil. When I’m done I lift the mower up out of the way onto one of the overhead shelves. I also use the crane to pick up stuff and set it on an overhead loft,” says Mariner.
He notes that he installed a cable connected to a turnbuckle on top of the track to help keep it level.
