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.

Abstract: A shield for radiation used for scanning freight containers is relocatable by cranes and lifts found in freight terminals. The relocatable radiation shield comprises a shield block having at least one solid shielding layer. A layer of the relocatable shield is adapted to hold a shielding fluid for altering a shielding property of the relocatable shield. The fluid-containing layer may optionally be a fluid container attached to or partially embedded within the shield block. The shielding fluid may be removed to reduce the weight of the relocatable radiation shield. In some embodiments the relocatable shield has a channel large enough for passage of a freight container on a conveyance such as a railroad car. An extended shielding structure for shielding a selected path may be assembled from two or more relocatable radiation shields. Some embodiments of a relocatable radiation shield include a freight container.
