  • Patent number: 8677905
    Abstract: In one aspect, the invention is directed to a load maneuvering system that includes a pair of runway rails, a bridge that is movable on the runway rails and that includes a single bridge rail, a carriage that is movable on the single bridge rail, and a manipulator supported by the carriage. The bridge rail is configured to support the assembly of the carriage and manipulator when a load is carried by the manipulator and a resultant moment is imposed on the bridge rail. The moment may be imposed in a direction about the bridge axis, in a direction about the runway axis, or a combination of the two. By providing a single bridge rail with an enclosed member as part of (or the entirety of) the bridge rail, the overall system is lighter and requires less power for movement of the bridge on the runway rails, and requires less power to move the carriage on the bridge. Additionally, the assembly is simplified relative to some load maneuvering systems of the prior art thereby making it less expensive to manufacture.

  • Patent number: 8061495
    Abstract: An apparatus for coupling power from shore power to a rubber tire gantry (RTG) crane comprises a power junction trolley and optionally an RTG crane. The power junction trolley receives power through a high voltage cable or alternatively through an inductive power coupling and alternatively outputs a low AC or a low DC voltage through a flexible power cable for connection to an RTG crane. A guiding apparatus directs the power junction trolley along a selected path so as to reduce a control accuracy requirement for the RTG crane. The RTG crane may move from a selected path to another selected path without interrupting a high voltage connection. The power junction trolley optionally determines its position relative to a selected path comprising a guide rail in some embodiments and a guide wire in others. Embodiments of the power junction trolley are alternately self-propelled or towed by the RTG crane.
