Abstract
An unloading mechanism for a truck or trailer has a conveyor belt which runs on the bed of the truck or trailer between forward and rearward wind-up rolls. A bulkhead is attached to the conveyor belt for pushing a load out the back of the back or trailer. Extending and retracting brace rods are provided on the bulkhead for automatic extension and retraction between relatively vertical positions when the bulkhead is located at a forward loading position in the truck or trailer and relatively inclined support positions when the bulkhead moves beyond the back opening of the truck or trailer. In the relatively inclined positions, the bracing rods resist tipping of the bulkhead about its connection with the conveyor belt thereby stablizing the load pushing forces when the load is moved beyond the back end of the truck or trailer.
