Bin Crane Built From Combine
Bill Powell and his father-in-law Don Adams, who both farm north of Youngstown, Alberta, wanted to add a fifth ring to some of their granaries. On others, they wanted to replace wooden floors. They decided to build a mobile crane that could handle both jobs.
Using parts from an old Knutsen bale stacker and an International 403 combine, plus some other odds and ends, they built a crane that is both mobile and adjustable to different diameters of bins.
The running gear - wheels, axle and transmission - are from the combine. The hitch is from an old cultivator. The long lift arm is 4-in. sq. tubing taken from the frame of the stacker. The short lift arm which is on a flexible mount can be hinged in and out to accommodate wider or narrower bins.
The winch at the base of the lift arm, driven by an orbit motor, was built using shafts and bearings from the combine. The transmission (from the combine) is used to gear the winch down slow enough that it can be moved a fraction of an inch at a time.
The crane has enough lift to allow Powell and Adams to pick up a 4-ring bin and put a hopper bottom under it, or they can use it to pick off the roof to add a ring.
