To provide a power supplying system that facilitates operating a current collector to be brought into contact with an insulated trolley wire accurately.
The system has a target device 61 which is positioned with respect to a feeder and arranged near a traveling lane, the current collector prepared movably in a self-traveling crane device 10 in the lateral direction perpendicular to the traveling direction of the self-traveling crane device 10, in order to bring into contact with the feeder to supply power to a battery, a target detector 63 which is positioned with respect to the current collector and arranged in the self-traveling crane device 10, and picks up a video of the target device 61, a moving mechanism which adjusts the position of the current collector to the self-traveling crane device 10, and a calculation unit 75 which calculates a displacement quantity in the width direction of the current collector to the feeder, based on the video of the target device 61 picked up by an imaging unit. The moving mechanism moves the current collector relative to the self-traveling crane device 10 by the displacement quantity calculated by the calculation unit 75.
