Abstract (en)

A power supply apparatus is provided with: at least one power collector (39) which supplies electric power to a rechargeable battery equipped on a self-traveling crane (10); and a position adjusting section (30A) which is provided between a crane main body of the self-traveling crane and the power collector, and which adjusts a position in a widthwise direction orthogonal to a traveling direction of the self-traveling crane, of the power collector with respect to the self-traveling crane. The power collector comes in contact, through an opening formed in an insulation cover (42) which covers the power supply section, with a power supply section (43) which is provided on a side section on a traveling pathway of the self-traveling crane, and supplies electric power to the self-traveling crane. The opening is formed in a region including a bottom section of the insulation cover facing a pathway surface where the self-traveling crane travels, and opposite end sections (44,45) of the insulation cover in the traveling direction of the self-traveling crane.
