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
