Abstract
A watertight door system that provides for subdivision of cargo holds, and having a door frame assembly with a sliding door. Conveyor support stringers are movably connected to the sliding door and conveyor idlers are movably connected to and the conveyor support stringers. A linear actuator associated with the door frame assembly selectively actuates the door between an open and closed position, whereby actuation of the door by the hydraulic cylinder causes the conveyor support stringers to move with the door, and the conveyor idlers to be lowered without removal thereof. Belt side plugs are positioned on either side of the door frame assembly, and can move both inwardly against a conveyor belt edge and outwardly from the conveyor belt edge.
