Abstract: A cover assembly for vehicles, such as coal trucks, hopper cars and the like. The assembly includes a rigid cover which is mounted to the body of the vehicle by an easily engagable hinge assembly to provide a cover which can be selectively hinged to either side of the vehicle to provide a movable roof. The roof can be opened to either side of the vehicle so as to expose the coal and permit the same to be sampled or removed by an auger or other suitable mechanisms through the top of the coal carrier.
Abstract: A vertically displaceable rigid cover for a truck bed is connected to the truck bed by many of pair of linkages on each side of the truck bed. A fluid pressure actuated cylinder is associated with each linkage for lifting and lowering the rigid cover, and for causing a portion of each linkage to be received into and continuously urged against a vertical stop means mounted on the truck bed.
