New Exhaust-Powered Dump Bag For Pickups
The dump kit makes use of exhaust-powered bags that were first developed for use as portable car and truck jacks. 'We started using them to dump truck and trailer boxes because it's much easier and less expensive to use engine exhaust than hydraulics," says Ron Irvine, national sales manager.
The dump bag mounts on a steel-reinforced plywood frame that's positioned on mounting brackets above the truck chassis. A second plywood frame fastens to the underside of the pickup box. The bag is inflated when a cable-controlled diverter valve, positioned near the end of the tail pipe, is closed, forcing exhuast air up into the bag. It requires just 8 lbs. of pressure to lift up to 2 tons.
"The entire air bag lift kit weighs just 30 lbs. compared to nearly 600 lbs. for some hydraulic systems. And it's easy to install by yourself," says Irvine, noting that the lift kit sells for "less than $400" in the U.S.
