ABSTRACT:
A conventional bottom dump truck includes doors which in a closed position are suspended underneath the bottom opening of the hopper of the trailer. The doors are opened outwardly and upwardly by pivotal action about an upper suspension point of each of the doors. The amount of movement of the door is limited by an abutment member mounted upon a vertical flange on the outside surface of the hopper bottom. The abutment member includes an abutment plate extending outwardly from the flange together with a bracket which has a slot slidable along the length of the flange and locatable at different points along the length of the flange by a pin passing through openings in the bracket and one of a plurality of openings in the flange. The flange can be rotated about an axis longitudinal of the flange to move the abutment member out of the path of the abutment on the door and simultaneously to move a second abutment member into engagement with the door which is positioned at the maximum allowable opening of the door.
