Bidirectional side dump trailer

Abstract

The present invention is directed to a bidirectional side dump trailer which includes a wheeled frame having a forward end, a rearward end and opposite sides and four tub supports mounted on an upper surface of the wheeled frame, two supports being positioned forward on the frame and two supports being positioned rearward on the frame, thus forming a generally rectangular support base for the containment tub. The containment tub includes a base wall, at least two side walls, a front wall and a rear wall thereby defining an open-top containment tub. The tub also includes exterior and interior surfaces. Mounted on the containment tub on the exterior surface thereof are four pivotable support connectors which extend downward from the containment tub to each engage a respective one of the tub supports when the containment tub is mounted atop the wheezed frame. For securing the pivotable support connectors to the tub support, four releasable locking devices are mounted on the frame adjacent a respective one of the tub supports. The releasable locking devices act to secure the pivotable support connectors to the tub supports, and by alternately releasing two locking devices on one side of the frame, the containment tub may be tilted and pivoted about the pivot axis formed by the secured pivotable support connectors on that side of the frame. Reversal of the sides results in dumping to the opposite side of the frame. Finally, for lifting the containment tub to a tilting position for dumping of the materials therein, a lifting system is mounted on the wheeled frame beneath the containment tub.
