Abstract: A conveyor cargo handling system for the synchronized, computerized loading and unloading of cargo containers from a vessel is comprised of at least two conveyor lines. Individually powered conveyor units, idler conveyor units, translate powered conveyor modules (“TPCM”), and rotate powered conveyor modules (“RPCM”), are remotely computer coordinated to operate in concert to safely and efficiently control traffic flow on the container terminal. The system eliminates much of the ground transportation conventionally utilized to move cargo containers to their storage destination.

Abstract: An extensible conveyor system that uses idler shuttles that include a base with sides, a front section and a rear section, and a mechanism that allows the frame to be moved along a support, these mechanisms may be wheels, slides, bearings, bushings, or other carriers, the sides of the base being generally symmetrical. The idler shuttles also include an idler support frame that extends from the base at an angle, the angle may be perpendicular or any other angle, the idler support frame being mounted between the front portion and the rear portion, the front portion of the base being adapted for nesting within the rear portion of the base, so that several of the support frames can be nested against one another to reduce the overall space taken up by the shuttles when the conveyor system is in a retracted position.

Abstract: A system for transporting material recovered in a dredging operation performed by a dredge is disclosed. The system includes a water-borne material distribution vessel including a conveyor system for receiving and depositing the recovered material. It also includes at least one water-borne material transportation vessel for transporting recovered material from the dredge to the material distribution vessel. The water-borne material distribution vessel can deposit the material into the waterway to form an island (which may be a levy), into another water-borne vessel, or into an on-shore station such as a wheeled transportation vehicle.
