To realize highly efficient power transmission even when a distance between a power transmission device and a power reception device changes.SOLUTION: This power supply system for a crane hook part comprises: a power supply device which is provided to the side of a hoist rope fixed to the jib of a crane; a power reception device which is provided closer to the cane hook side of the crane than the power transmission device, a position information acquisition unit which acquires position information about the power reception device; and a control unit which controls each reactance so that each reactance of each variable reactance circuit can have each value determined on the basis of the transmission efficiency of power calculated by using a circuit equation representing the power transmission device and the power reception device with each self-inductance of each coil and mutual inductance between the coils acquired when the power transmission device and the power reception device are arranged in a positional relationship based on the position information acquired by the position information acquisition unit as constants and each reactance as a variable.SELECTED DRAWING: Figure 4

    【課題】送電装置と受電装置の距離が変化する場合でも高効率な電力伝送を実現する。【解決手段】クレーンフック部の給電システムは、巻き上げロープのクレーンのジブに固定される側に設けられた送電装置と、送電装置よりもクレーンのクレーンフック部側に設けられた受電装置と、を備え、さらに、受電装置の位置情報を取得する位置情報取得部と、各可変リアクタンス回路の各リアクタンスが、送電装置と受電装置とを位置情報取得部が取得した位置情報に基づく位置関係に配置した場合に得られる各コイルの各自己インダクタンスおよび各コイル間の各相互インダクタンスを定数とし、各リアクタンスを変数とする送電装置および受電装置を表す回路方程式を用いて算出された電力の伝送効率に基づき決定された各値を有するように、各リアクタンスを制御する制御部と、を備える。【選択図】図4
