To provide means for suppressing the separation of a utility pole from a holding device unintentionally.SOLUTION: The road-rail vehicle includes a traveling body and an upper working body mounted on the traveling body. The upper working body includes a holding device and an operation cabin. The operation cabin includes an operation device 70 for operating the holding device. The operation device 70 includes an operation lever 71 for outputting an opening signal and a closing signal corresponding to the operation amount, an operation button 73 for outputting a detection signal upon accepting an operation by an operator, and a control unit 75 into which the opening signal, the closing signal, and the detection signal are input. The control unit 75 outputs a driving signal for closing a movable pawl 53 on condition that it accepts the closing signal whereas the control unit outputs a driving signal for opening the movable pawl 53 on condition that it accepts the detection signal and the opening signal.SELECTED DRAWING: Figure 3
【課題】把持装置が電柱を意図せず離すことを抑制する手段を提供する。【解決手段】軌陸車は、走行体と、走行体に搭載された上部作業体とを備える。上部作業体は、把持装置と操作用キャビンとを備える。操作用キャビンは、把持装置を操作する操作装置70を備える。操作装置70は、操作量に応じた開信号及び閉信号を出力する操作レバー71と、操縦者による操作を受け付けると検知信号を出力する操作ボタン73と、上記開信号及び閉信号と上記検知信号とが入力される制御部75とを有する。制御部75は、閉信号を受け付けたことを条件に可動爪53を閉じる駆動信号を出力し、検知信号及び開信号を受け付けたことを条件に可動爪53を開く駆動信号を出力する。【選択図】図3
