  • Patent number: 8439180
    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.
    Type: Grant

  • Publication number: 20100124469
    Abstract: A twistlock having an increased tension load limit that is based on a physical configuration that has a massive amount of material removed from the shaft of the twistlock. Two parallel, circular cross-section rabbets are cut at the intersection of the shoulder of the truncated conical extension formed at one end of the shaft that forms the twistlock. The tensional loading limit in this configuration is greatly enhanced.

  • Patent number: 7624883
    Abstract: The present invention utilizes a hoist drum with a three different drum sections, two cylindrical and one tapered, upon which the different ends of a lifting cable simultaneously spool on and off of as a function of counterclockwise and clockwise cable spooling. This combination reduces the amount of shaft torque required to raise or lower a load while increasing the number of hoist drum rotations required to raise or lower that load. These two features are incorporated into the operation of a main crane cable length adjusting device since they offer precise and rapid adjustment capabilities to be made with smaller sized electric motors and clutches.
