PROBLEM TO BE SOLVED: To provide a stairway raising/lowering apparatus that is able to satisfactorily carry a to-be-carried target while restricting an increase in the number of components.SOLUTION: A stairway raising/lowering apparatus 1 comprises a base frame 60, a main track frame 30, and an auxiliary track frame 40. The auxiliary track frame 40 is provided between a grounding position where a crawler belt 24 is brought into contact with a grounding surface and a separation position where the crawler belt is separated from the grounding surface. On the rear-end side of the base frame 60, a pressing surface 61a is provided. When the front end of the base frame 60 is inclined upward by a telescopic cylinder 71, the pressing surface presses a connection member 51 connected to the auxiliary track frame 40, and moves the auxiliary track frame 40 toward the grounding position. The base frame 60 and the connection member 51 are coupled via an urging member 73 to which urging force has been applied in a shortening direction.SELECTED DRAWING: Figure 2
【課題】部品点数の増加を抑えつつ、運送対象を良好に運ぶことが可能な階段昇降装置の提供。【解決手段】階段昇降装置1は、基台フレーム60と、主軌道フレーム30と、補助軌道フレーム40とを備えている。補助軌道フレーム40は、クローラベルト24を接地面に接地させる接地位置と接地面から離間させる離間位置との間で移動自在に設けられている。基台フレーム60の後端部側には、伸縮シリンダ71によって基台フレーム60の前端部が上方へ傾動されると、補助軌道フレーム40に接続される接続部材51を押下して、補助軌道フレーム40を接地位置に向けて移動させる押下面61aが設けられている。基台フレーム60と接続部材51とは、短縮方向に付勢力が付与された付勢部材73を介して連結されている。【選択図】図2
