Mobile transport for fluid cargo

摘要

A wheel-supported, fluid-tight, top filling, rear discharge cargo box having a door pivotally supported in suspension for closing the rear discharge opening, a hydraulically actuated latching mechanism for controlling the operation of the door and a drag chain totally confined within the cargo box characterized by a pair of horizontally spaced, endless chain members disposed in horizontally spaced vertical planes and a discontinuous series of drag bars extended between the lower runs of the chain members for the drag chain defining a load receiving opening between the opposite ends of the series for facilitating a top-loading of the cargo box.
