PROBLEM TO BE SOLVED: To realize an electric power transmission with high efficiency in arbitrary positional relation.SOLUTION: The electric-power supply system of the crane hook part comprises a power transmission device installed on the crane jib and a power receiving device on the crane hook part, and further comprises a positional information acquisition unit to obtain positional information of the power receiving device, and a control unit defining each self-inductance of each coil and each mutual inductance among each of the coils as a constant, which are obtained when the power transmission device and power receiving device are arranged in the positional relation based on the positional information acquired by the positional information acquisition unit, the control unit controlling so that each reactance of each variable reactance circuit, the first variable reactance circuit and the second variable reactance circuit have each value which is determined based on the power transmission efficiency calculated by using the circuit equation representing the power transmission device and power receiving device with each reactance as a variable.SELECTED DRAWING: Figure 2
