Abstract The invention provides in one aspect, an unloading system for a truck or a trailer. The truck or trailer having a load carrying area defined by a tray base with a pair of sidewalls and a tailgate. The unloading system includes at least one ram that is carried on the respective truck or trailer. The ram drives a blade that extends laterally across the width of the load carrying area of the truck or trailer, and is shaped so that it is adapted to form an effective seal between the sides of the blade and each respective sidewall of the load carrying area. The ram is adapted to drive the blade from a normally retracted position, at the forward end of the load carrying area, to a fully extended position, where the blade is at the rearmost position of the load carrying area, in the vicinity of the tailgate, thereby forcing the payload to unload from the rear of the truck or trailer. The ram in either the truck or the trailer are operable by the operator either simultaneously, or individually, from within the truck cabin, or externally to the truck cabin, at a safe distance, via a wired or wireless remote control.
