"Elevator-Style" Boom Lifts Up To 34 Ft. High

Using mostly junk material, Chuck Van Boening, Bladen, Neb., built a pull-type "boom" that he uses to take down or erect grain bins and do other high-lift jobs like putting up rafters on pole sheds.
  Van Boening recently sent FARM SHOW photos of the rig lifting the top half of a 10,000-bu. bin that he moved to another location.
  The two-wheeled rig looks somewhat like a bale elevator except that it has a steel catwalk on it instead of a chain and apron. The catwalk came off the top of a wrecked railroad car and has a safety railing on both sides of it. The back part of the catwalk angles downward so that when the rig is raised to its maximum height 36 ft. - the catwalk extends almost straight out. The machine is raised or lowered by an orbit motor that operates off tractor hydraulics and drives a heavy-duty winch. A chain and big hook do the lifting.
  The rig's main frame is made from 1/2-in. angle iron and oil field pipe. The 24-in. high wheels are off an old Baldwin self-propelled combine and the axle is off a Deere self-propelled combine, which Van Boening widened by welding on more steel. The wheels are spaced 16 ft. apart.
  "It's built heavy and works great. "However, it took a long time to build," says Van Boening. "I worked on it on and off for a month. I recently used it to repair a 50-ft. high radio antenna next to our house. The first time most people see it they have no idea what it is.
  "It cost a lot less to build this boom than to hire a crane, and it works much faster than using bin jacks. Whenever we move a bin we hook a tire onto the chain in order to evenly distribute the bin's weight. Whenever we take grain bins apart we have four men operating electric wrenches two inside the bin and two outside it. It takes us less than four hours to take a bin down.
  "The winch runs pretty slow so it doesn't jerk. It's a worm drive model so it can't free wheel', which could be dangerous."
