To provide an ascending/descending assist device having improved support force for supporting a load in the ascending/descending direction.SOLUTION: There is provided an ascending/descending assist device 100 that assists a worker in ascending and descending along a long lifting rail R20 having a plurality of holes R21A drilled at regular intervals in the longitudinal direction with a fall prevention device worn by the worker attached thereto. The ascending/descending assist device includes a main body 110 that is slidably engaged with the long lifting rail R20, and a wheel 133, made up of a plurality of track plates 133A, which is driven forward and backward to ascend and descend along the long lifting rail R20. The wheel 133 is provided with a plurality of blocks 133B each of which is configured to be engaged with the holes R21A and protrudes from the plurality of track plates 133A. Two or more of these blocks 133B can be driven forward and backward while maintaining engagement with the holes R21A.SELECTED DRAWING: Figure 5
【課題】昇降方向の荷重を支持する支持力の向上が図られた昇降補助装置を提供する。【解決手段】作業者が着用する墜落制止用器具が取り付けられた状態で長手方向に一定の間隔で複数の孔Ｒ２１Ａが穿設された長尺昇降用レールＲ２０に沿って昇降する、作業者の昇降を補助する昇降補助装置１００であって、長尺昇降用レールＲ２０にスライド可能となるように係合する本体部１１０と、複数の履板１３３Ａから構成される輪を進退駆動させることで、長尺昇降用レールＲ２０に沿った昇降を行う輪１３３と、を備え、輪１３３は、複数の履板１３３Ａから突設されて、それぞれが孔Ｒ２１Ａと噛み合うように構成された複数のブロック１３３Ｂを備え、これらのブロック１３３Ｂのうち２つ以上が孔Ｒ２１Ａと噛み合った状態を維持しながら進退駆動することが可能である。【選択図】図５
