To provide a movement mechanism of a crane device capable of preventing the crane device from getting caught on an overhead power line at a time of a derricking operation of the crane device.SOLUTION: A movement mechanism 120 of a crane device has a frame 115 arranged movably on a vehicle body 102 of a railroad crane 100, a crane device 107 installed on the frame 115, and a driving means 123 connected to the frame 115 and to the vehicle body 102, and at the time of derricking the crane device 107, the driving means 123 moves the crane device 107 to the position where the crane device 107 does not interfere with the overhead power line range in the railroad track. The movement mechanism of the crane device is characterized by the above procedure.SELECTED DRAWING: Figure 4

    【課題】クレーン装置の起伏操作時に、クレーン装置が架線に引っ掛かることを防止するクレーン装置移動機構を提供する。【解決手段】鉄道クレーン100の車体102上に移動可能に配置された架台115、前記架台115上に設置されたクレーン装置107、及び前記架台115及び前記車体102に連結された駆動手段123を有し、前記駆動手段123は、前記クレーン装置107の起伏時に前記クレーン装置107が線路内架線範囲に干渉しない位置まで前記クレーン装置107を移動させることを特徴とするクレーン装置移動機構120により解決される。【選択図】図4
