ABSTRACT:
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.
