Abstract
A dump truck body has a bed and side walls defining a rear opening which is closed by a tailgate and loader unit removably attached to adaptor brackets inserted into the side walls. The unit includes a U-shaped frame supporting extendable tracks which carry a vertical tailgate supported for pivotal movement to form a horizontal platform. The frame also encloses two pairs of oppositely directed hydraulic cylinders which move the tracks, and a cam mechanism is shifted into alignment to pivot the tailgate between horizontal and vertical positions in response to movement of the tracks. The entire unit is pivotally supported by the adaptor brackets to pivot from the truck body when the body is inclined for dumping.
