PROBLEM TO BE SOLVED: To provide a road-rail vehicle capable of horizontally moving an electric pole without rotation even while gripping and fixing the electric pole.SOLUTION: The road-rail vehicle is provided with a travel body, and a gripping device that is mounted on the travel body. The gripping body is provided with: a turning body; a boom that extends from the turning body; a gripping mechanism that is rotatably provided at a tip of the boom; a hydraulic motor M that rotates the gripping mechanism; and a hydraulic device 80 that supplies hydraulic oil to the hydraulic motor M. The hydraulic device 80 is provided with a selector valve 81 that forms a pair of bypass flow passages 84 of the hydraulic motor M. The selector valve 81 opens/closes the bypass flow passages 84 in response to a driving signal from a control device. While the selector valve 81 closes the bypass flow passages 84, the hydraulic oil is supplied to the hydraulic oil M to rotate the gripping mechanism. When the selector valve 81 opens the bypass flow passages 84, the hydraulic pressure of the hydraulic motor M is released. Thus, the gripping mechanism can be rotated by human power.SELECTED DRAWING: Figure 4

    【課題】電柱を把持して固定しながらも、電柱を回動させずに水平移動させることができる軌陸車を提供する。【解決手段】軌陸車は、走行体と、走行体に載置された把持装置とを備える。把持装置は、旋回体と、旋回体から延びるブームと、ブームの先端に回動可能に設けられた把持機構と、把持機構を回動させる油圧モータMと、油圧モータMに作動油を供給する油圧装置80とを備える。油圧装置80は、油圧モータMの一対のバイパス流路84を形成する切替弁81を備える。切替弁81は、制御装置からの駆動信号によりバイパス流路84を開閉する。切替弁81がバイパス流路84を閉じているとき、油圧モータMに作動油が供給され、把持機構が回動される。切替弁81がバイパス流路84を開くと、油圧モータMの油圧が開放される。その結果、把持機構を人力で回動させることができる。【選択図】図4
