Exhaust-Powered Dump Bag For Pickups
"It was an inexpensive way to turn a pickup into a dump truck," says Denis Desjardins, Alcove, Quebec, who converted a 1975 Chevrolet 1/2-ton 4-WD pickup into a dump truck by fitting it with an exhaust-powered Australian-made dump bag that he read about in FARM SHOW (Vol. 14, No. 6).
The heavy nylon canvas bags are fitted with one-way valves that let air in but don't allow it to escape. The bag mounts between two sheets of plywood, one on the frame of the truck and the other on the underside of the box. A fill hose attached to the bag is fitted with a rubber cup. To dump a load, you just hold the cup over the truck exhaust pipe. The bag fills in less than half a minute to dump the load. To lower the box, you simply open a valve on the hose.
"I built it for a friend who uses it to do handyman work hauling wood, sod, etc. The air bag eliminates the need for expensive and complicated hydraulics. The bags inflate with as little as 8 psi yet will lift up to 1 1/2 tons. The company I bought the bag from no longer sells them so I don't know where to get another one."
