To provide a load receiving platform lifting/lowering device in which a bent portion of hydraulic piping does not interfere with a tilt cylinder.SOLUTION: The load receiving platform lifting/lowering device is provided that comprises: a load receiving platform 2 having a pair of stiffeners 22 on the back side; a lifting/lowering mechanism lifting and lowering the load receiving platform 2; a tilt cylinder 4 arranged inside the pair of stiffeners 22, and turning the load receiving platform 2; a hydraulic drive mechanism 5 sending hydraulic oil to the tilt cylinder 4; and hydraulic piping 6 connecting the hydraulic drive mechanism 5 and each tilt cylinder 4 to each other, and arranged inside the pair of stiffeners 22. One stiffener 22 L has one side communicative hole 221 L opened in the surface side of the load receiving platform 2 in a position being far from the turning center of the load receiving platform 2 than the tilt cylinder 4 L. The hydraulic piping 6 is introduced into the one stiffener 22 L from the hydraulic drive mechanism 5, and connected to the tilt cylinder 4R arranged inside the other stiffener 22R through the one side communicative hole 221 L.SELECTED DRAWING: Figure 2

    【課題】油圧配管の曲げられた部分がチルトシリンダに干渉しない荷受台昇降装置を提供する。【解決手段】裏面に一対のスチフナ22を有する荷受台2と、荷受台2を昇降させる昇降機構と、一対のスチフナ22内部に配置され、荷受台2を回動させるチルトシリンダ4と、作動油をチルトシリンダ4に送出する油圧駆動機構5と、油圧駆動機構5と各チルトシリンダ4とを結び、一対のスチフナ22内部に配置された油圧配管6とを備え、一方のスチフナ22Lは、チルトシリンダ4Lよりも荷受台2の回動中心から遠い位置に、荷受台2の表面側に開口した一方側連通穴221Lを有し、油圧配管6は、油圧駆動機構5から一方のスチフナ22Lに導入され、一方側連通穴221Lを介して他方のスチフナ22R内部に配置されたチルトシリンダ4Rに接続される荷受台昇降装置である。【選択図】図2
