Self-Unload System Fits Any Truck, Trailer
 |
 |
The system consists simply of a cable-powered drag "board" that's pulled along the floor of the trailer. The metal drag board is flared so, that when pulled toward the back of the trailer, it stands straight up and pulls grain to the rear. When pulled back to the front, it rides flat against the trailer floor with little resistance. Two cables strung between pairs of pulleys at the front and back of the trailer and driven by a heavy-duty winch mounted under the trailer bed ù automatically pull the 1-ft. tall drag board back and forth until the trailer is empty.
"It takes just 15 to 20 min. to empty a 20-ton load," says Hesse, noting that the uncomplicated system can handle most any flowable commodity, including grain, fertilizer, lime,sawdust and even bales of hay or straw.
The cable system takes up virtually no space in the trailer. Powered by a 16 gal. hydraulic pump, the winch mounts beneath the trailer bed. Hydraulic controls can be positioned anywhere on the trailer. Everything bolts easily to the trailer with an electric drill and hand tools. It can be easily transferred from one truck to another.
"The gearbox, bearings, drives, cables and pulleys are all top quality, designed to last the life of the truck," says Hesse.
The unload system can be sized to fit any size truck or trailer bed and sells for around $4,000.
