Abstract (en)
[origin: WO2009002509A1] 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.
