This invention relates to a towable trailer having a tipping tray. The tipping tray incorporates an axle and wheels, and is mounted to the trailer\s chassis via a pivot. The chassis incorporates a guide slot which accommodates the tray\s pivot. A cam arrangement is provided to control the rate and angle at which the tray is tipped. To tip the tray, the trailer is reversed, and the towing vehicle suddenly braked. The tray continues to move in the reverse direction by virtue of its inertia. The pivot of the tray slides rearward within the guide slot, while the cam on the tray bears against a follower on the chassis to tip the tray.

A wheeled vehicle with front latching means comprising a chassis incorporating a tow bar at a front end; a tipping tray secured to at least one axial member supporting ground wheels; articulation means comprising a pivot with a transversely disposed axis, secured to the tray; guiding means secured to the chassis and adapted to slidably accommodate for longitudinal displacement said articulation means; camming means longitudinally spaced apart from the articulation means and comprising at least one cam and one cam follower, the cam being secured to the tray and the cam follower being secured to the chassis and adapted to cooperate to alter the angular disposition of the tray between a carriage position and a discharge position when a sudden change in the vehicle\s inertia causes a net rearward force on the tipping tray causing the pivot to be moved longitudinally of the guiding means in so doing the camming action of the camming means articulating the tray about the axis of the pivot, whilst latching means adapted to maintain the disposition of the chassis and tray relative to one another are disengaged, and wherein, in the carriage position, the tray is in a substantially parallel relationship with the chassis, and the cam follower is disposed at the beginning of the cam.
