To easily obtain sufficient braking force even when the weight of a self-propelled elevating device is heavy.SOLUTION: A self-propelled elevating device elevates or lowers along a longitudinal direction of a narrow and long path member 100 extending in a vertical direction or in a direction inclined to the vertical direction, and comprises a braking portion 6 for braking the self-propelled elevating device by clamping the path member between a clamping portion 61a and a receiving member 62 of a rotary member 61 rotating around a predetermined rotation axis 61b. The rotary member is configured so that the distance between the clamping portion and the receiving member approaches when the clamping portion rotates in a forward rotational direction F accompanying the path member when the self-propelled elevating device moves in a downward direction.SELECTED DRAWING: Figure 6
【課題】自走式昇降装置の重量が重い場合でも十分な制動力を容易に得る。【解決手段】鉛直方向又は鉛直方向に対して傾斜する方向に延びる細長の経路部材100の長手方向に沿って昇降する自走式昇降装置であって、所定の回転軸61bの回りで回転する回転部材61の挟持部分61aと受け部材62とで前記経路部材を挟持することにより、当該自走式昇降装置を制動させる制動部6を有し、前記回転部材は、当該自走式昇降装置が下降方向へ移動するときに前記挟持部分が前記経路部材に連れ回る正転方向Fへ回転すると、該挟持部分と前記受け部材との距離が近づくように構成されている。【選択図】図6
