Abstract
Abstract A portable trailer equipped with a rotatable bed plate hinged to the rear of the trailer and normally located within the confines of the trailer sides with a telescopic hydraulic cylinder mounted to the underside of the front of the bed plate and to the trailer frame so as to elevate the bed plate for dumping the contents of the bed. A gasket is mounted along the side and front edges of the bed plate so as to prevent material on the bed plate from falling off the side and front edges of the bed plate.
