Summary:PROBLEM TO BE SOLVED: To provide an electric power feeding device of a crane shortening working time when attaching/detaching a connector, improving safety of the attaching/detaching work and reducing cost required for the work, without generating breakage of a cable extending from the connector and with high durability. SOLUTION: In this electric power feeding device 1 of the crane 60 performing cargo handling of a marine transportation container 53, electric power is fed to the crane 60 from an electric power feeding wire 6 installed along a lane 52 storing the container 53 via a moving truck 5 for electric power feeding moving along the electric power feeding wire 6 and via a connector part 2. The connector part 2 is constituted of a male part 3 and a female part 4. The male part 3 includes a collector holding bar 11 connected to a derricking device 10 and a collector 12 installed in the collector holding bar 11. The female part 4 has a rigid body trolley 13 in electric contact with the collector 11. By an operation of the derricking device 10, the collector 12 and the rigid body trolley 13 are constituted to be attachable/detachable. COPYRIGHT: (C)2011,JPO&INPIT
