To provide a floor board installation device for an outrigger capable of automatically installing a floor board under a ground plate in conjunction with the extension operation of the inner box of a vertical outrigger box.SOLUTION: A floor board installation device 1 for an outrigger comprises a floor board 30 with a floor board body 31 having a larger ground contact area than that of a ground plate 85, an arm 20 with one end connected to the board surface of the floor board body 31, and an outer side guiding mechanism 4 and a grounded side guiding mechanism 5, where the outer side guiding mechanism and the grounded side guiding mechanism keeps the posture of the floor board 30 in a floor board storage posture where the board surface of the floor board body 31 is parallel to the side surface of an outer box 83 by fixing the arm 20 to the outer box 83 when an inner box 84 of a vertical outrigger box 82 is most shrunk. In conjunction with the extension operation of the inner box 84, the outer side guiding mechanism and the grounded side guiding mechanism act on the arm 20 and guide the displacement of the floor board 30 so that the posture of the floor board 30 changes from the floor board storage posture to a floor board installation posture in which the floor board body 31 is laid between the ground plate 85 and the ground.SELECTED DRAWING: Figure 3

    【課題】縦アウトリガボックスのインナボックスの伸長動作に連動させて敷板を自動で接地板の下に敷設することが可能なアウトリガ用敷板設置装置を提供する。【解決手段】アウトリガ用敷板設置装置1は、接地板85よりも広い接地面積を有する敷板本体31を有する敷板30と、一端部が敷板本体31の板面に接続されたアーム20と、縦アウトリガボックス82のインナボックス84の最縮小時に敷板30の姿勢を、アーム20をアウタボックス83に固定することで敷板本体31の板面がアウタボックス83の側面と平行となる敷板格納姿勢に維持すると共に、インナボックス84の伸長動作に連動して、アーム20に作用し敷板30の姿勢が敷板格納姿勢から接地板85と地面との間に敷板本体31が敷設された敷板設置姿勢へと変化するように、敷板30の変位を案内するアウタ側案内機構4及び接地側案内機構5とを備える。【選択図】図3
