ABSTRACT:
A dual tarpaulin unloading system which rests in the bed of a vehicle. The second end of the first tarpaulin is attached to the bed of the vehicle by a single mechanical arrangement which allows the unloading system to detach after the unloading cycle is complete. The payload to be transported and unloaded rests on the upper surface of the second tarpaulin. At the dumping site, the vehicle door bed is opened and the first end of the first tarpaulin and the first end of the second tarpaulin are attached to a drawing strap. The opposite end of the drawing strap is attached to established anchorage. The vehicle then moves in a direction away from the established anchorage. The weight of the payload on the first and second tarpaulin coupled with the movement of the vehicle forces the payload off the vehicle bed and onto the ground.
