Abstract: The present invention relates to a detachably attachable moving headboard trailer ejector and floor cleaning apparatus for use with a self-unloading trailer having a front end, a rear end, side walls, and either a reciprocating slat conveyor floor or a conveyor belt floor. The invention comprises, in one embodiment, a base, a panel sweeper, one or more panel sweeper support members, a means for traversing the panel sweeper, a tether bar, side flanges, and a base flange. In use, the invention is placed in the front end of a self-unloading trailer and the trailer is loaded with material; when material is ejected from the trailer, the invention “rides” along the moving floor and pushes the material out of the trailer's back end. The rubber flanges ensure a snug fit within the trailer and keep post ejection residual material at a minimum.

Abstract: The present invention comprises a method of attaching plastic to a metal substrate and a part made by the method. A hydroformed metal section having top and bottom openings is provided. A plastic component is molded about the metal component and through the bottom opening. The plastic component includes a flange on one side thereof to secure the plastic component with the metal component.

Abstract: A transport trailer for transporting large agricultural spray vehicles has a platform supported by a plurality of wheels, and a pair of loading ramps to facilitate loading vehicles onto the platform. An operating mechanism is provided for pivoting the loading ramps between raised and lowered positions, and includes a pneumatic actuator and a J-shaped arm associated with each loading ramp. The trailer is also equipped with a plurality of tie down arms to automatically secure the spray vehicle to the trailer when the loading ramps are raised. A lock mechanism selectively locks the tie-down arms in their respective lowered positions. A sign having visual indicia, such as the words “WIDE LOAD,” is pivotally connected to a rear end of the trailer platform. The sign is interconnected with the operating mechanism for the loading ramps to pivot the sign between lowered and raised positions upon corresponding movement of the loading ramps.
