To prevent a change of a crane operation of a boom, a winch or the like when power to be supplied is switched between a vehicle engine and an APU in a crane truck.SOLUTION: A crane 100 comprises: a travel device 10; a swivel base 20; a cabin 40; a vehicle engine 13; an APU 90; and a power control device 90 that selectively switches between a vehicle engine mode and an APU mode. The power control device 90 does not switch between the vehicle engine mode and the APU mode when an input of an operation to an operation system for operating a boom is detected, and can switch between the vehicle engine mode and the APU mode when the input of the operation to the operation system is not detected.SELECTED DRAWING: Figure 4

    【課題】クレーン車において、供給する動力を、車両エンジンとAPUとの間で切り替えたときに、ブームやウインチ等のクレーンの動作が変化するのを防止する。【解決手段】クレーン100は、走行装置10と、旋回台20と、キャビン40と、車両エンジン13と、APU90と、車両エンジンモードとAPUモードとを選択的に切り替える動力制御装置90と、を備え、動力制御装置90は、ブームを動作させる操作系に対する操作の入力を検出したとき、車両エンジンモードとAPUモードとの切り替えを行わず、操作系に対する操作の入力を検出しないとき、車両エンジンモードとAPUモードとの切り替えを可能とした。【選択図】図4
