PROBLEM TO BE SOLVED: To secure a space in which a power device can be accommodated in a cross member of a vertical-type cargo receiving stage lifting apparatus.SOLUTION: A vertical-type cargo receiving stage lifting apparatus comprises: a hydraulic cylinder 60 provided in a cross member 50 coupling posts 10L and R; moving pulleys 80La and Ra being attached to the hydraulic cylinder 60 and reciprocating in the cross member 50; fixed pulleys 80Lb and Rb positioned at an opposite side to the moving pulleys 80La and Ra with the hydraulic cylinder 60 interposed thereamong; a wire 90 L being wound over the moving pulleys 80La and Ra and the fixed pulleys 80Lb and Rb and suspending a slider 30 L; and a wire 90R being wound over the moving pulleys 80La and Ra and the fixed pulleys 80Lb and Rb and suspending a slider 30R. The fixed pulley 80Rb is offset inside in a vehicle width direction with respect to the fixed pulley 80 Lb and the fixed pulley 80Rb is disposed between the hydraulic cylinder 60 and the post 10L while the fixed pulley 80Lb is being disposed such that a part thereof faces an internal space of the post 10L.SELECTED DRAWING: Figure 4
【課題】垂直式荷受台昇降装置のクロスメンバ内に動力装置を収容し得るようなスペースを確保する。【解決手段】ポスト10L,Rを連結するクロスメンバ50内に設けた油圧シリンダ60と、油圧シリンダ60に取り付けられてクロスメンバ50内を往復移動する移動滑車80La,Raと、油圧シリンダ60を挟んで移動滑車80La,Raと反対側に位置する固定滑車80Lb,Rbと、移動滑車80La及び固定滑車80Lbに掛け回されてスライダ30Lを吊り下げたワイヤ90Lと、移動滑車80Ra及び固定滑車80Rbに掛け回されてスライダ30Rを吊り下げたワイヤ90Rとを備え、固定滑車80Lbに対して固定滑車80Rbを車幅方向の内側にオフセットさせ、固定滑車80Lbをポスト10Lの内部空間に一部が臨むように配置する一方で、固定滑車80Rbを油圧シリンダ60及びポスト10Lの間に配置した。【選択図】 図4
