Reciprocating conveyor with top front drive

摘要

The container of a mobile cargo trailer is provided with a reciprocating slat type conveyor floor in which the elongated slats are supported at their lateral edges on V-shaped bearings which are mounted on Y-shaped supports integral with sub-deck sections on the container bottom and joined together with watertight seals. Three cross beams are connected to different groups of the slats and are coupled to hydraulic cylinders located outwardly of the front end of the container and in horizontal alignment with the slats. The cylinders are coupled to a hydraulic fluid pressure source through an arrangement of control valves to effect movement of the group of slats simultaneously in a load moving direction and sequentially in the opposite, slat-retracting direction, with interengaging abutments on the cross drives arranged for moving one of the cross drives and its slats by hydraulic power applied only to the other two cross drive cylinders.
