Abstract

The invention provides a power supply apparatus and a crane system. The power supply apparatus is provided with: at least one power collector which supplies electric power to a rechargeable battery equipped on a self-traveling crane; and a position adjusting section 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 which covers the power supply section, with a power supply section 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 of the insulation cover in the traveling direction of the self-traveling crane.

Description

technical field [0001] The invention relates to a power supply device and a crane system. Background technique [0002] Conventionally, self-propelled cranes that travel along passages of container yards have been known as cranes for transporting containers stored in container yards or the like. [0003] As an example of such a self-propelled crane, in (Japanese) Unexamined Patent Publication No. 2009-242101, a self-propelled crane (site crane) that includes a power supply device and a rechargeable battery and travels using the power stored in the rechargeable battery is described. . In the self-propelled crane described in (Japanese) Unexamined Patent Publication No. 2009-242101, a rail for power supply formed along the length direction of the passage is provided near the passage for storing containers, and the self-propelled crane is provided in contact with the rail in a telescopic or rotational manner. device for receiving electricity. According to the self-propelled ...
