ABSTRACT:
A dumping trailer wherein the cargo carrying surface of the trailer is movably mounted relative to the bed frame of the trailer. A cargo carrying surface is to be movable from the bed frame to an initially raised position while still being maintained substantially parallel to the bed frame. From this initially raised position, the cargo carrying surface is to be inclined to facilitate dumping of any cargo from the rear end of the trailer. When the cargo carrying surface is in the raised position, a locking mechanism is activated which holds the rear portion of the cargo carrying surface in this raised position as the cargo carrying surface is inclined.
