Abstract
A self-unloading, bottom-discharge trailer and a discharge conveyor therefore, are provided. In a working position, the discharge conveyor transports material from a trailer container upwards beyond the rear of the trailer for depositing into storage. In a transport position, a rear section of the discharge conveyor is folded downwards into a substantially vertical position, resting against the rear of the trailer frame and not substantially protruding beyond the back of the trailer. The frame may include a recess sized to accommodate the rear section such that the rear section is substantially flush with the rear of the frame. Consequently, the trailer may remain in compliance with highway safety regulations.
