Abstract
A conventional dump trailer includes discharge members or doors which are typically mounted beneath the trailer. The movement of the doors is controlled by a control device of the present invention having a position sensor which is mounted on the trailer and a sensor actuator mounted on the discharge member. The amount of movement of a door is automatically limited at a preselected position. The control device allows for the discharge member to be further moved to further positions.
