A bidirectional side dump trailer includes a wheeled frame having first and second forward and rearward tub supports mounted thereon, and an open-topped containment tub. First and second forward and rearward pivotable support connectors each include a generally horizontal pin rotatably mounted on the containment tub and a sleeve rotatably mounted on the pin, while the first and second forward and rearward tub supports each include a generally concave saddle portion adapted to receive a respective one of the forward and rearward pivotable support connectors therein. The containment tub is pivotably mounted on the wheeled frame by releasable connection of each of the first and second forward pivotable support connectors to a respective one of the first and second forward tub supports, and releasable connection of each of the first and second rearward pivotable support connectors to a respective one of the first and second rearward tub supports, the pin and the sleeve of the first and second forward and rearward pivotable support connectors operating such that upon the sleeve being seated in one of the generally concave saddle portions, the sleeve remains in a generally non-rotating position while the pin rotates within the sleeve. Releasable locking devices releasably secure the pivotable support connectors to a respective one of the tub supports, and at least one power cylinder mounted at one end on the wheeled frame and the other to the containment tub lifts and tilts the tub to dump the contents of the tub.
