The apparatus is a self propelled trailer with a bin with closed sides and a tailgate for collecting waste material directly as it is stripped from a building and dumping the material into a nearby vehicle. The entire bin can be moved out beyond the rear of the trailer and raised to the level as high as the eaves of a roof by the use of hydraulic pistons. The trailer can be moved under its own power to a dump truck, and, with the bin raised, the tailgate is opened and the bin is tilted rearward to dump its load over the side of a truck. Large hinged extension flaps at the top of the sides are held at an angle sloping into the bin to approximately double the "catch" area of the bin and prevent material from failing to the ground.
