Abstract | To suppress the decline in the versatility of a scaffold lifting device.SOLUTION: The scaffold lifting device 1 comprises a plurality of truss frames 2 extending in parallel and horizontally with a fixed distance from each other, a pulley 3 rotatable in a fixed state with respect to the truss frame 2, and a winch 4 fixed to the truss frame 2 at a position separated from the pulley 3 in the extending direction of the truss frame 2. In the device 1, a wire 6 extending from the winch 4 is connected to a working position which is wound around the pulley 3 and located above the truss frame 2. Then, with the scaffold attached on the plurality of truss frames 2, the scaffold is lifted to the working position by winding the wire 6 with the winch 4. The pulley 3 is fixed to the truss frame 2 via a support member that supports its central axis. The fixed position of the support member with respect to the truss frame 2 can be changed in the longitudinal direction of the truss frame 2.SELECTED DRAWING: Figure 1
【課題】足場吊上装置の汎用性の低下を抑制する。【解決手段】足場吊上装置1は、互いの間隔が固定された状態で平行且つ水平に延びる複数のトラスフレーム2と、同トラスフレーム2に対し固定された状態で回転可能とされている滑車3と、同滑車3に対しトラスフレーム2の延びる方向に離れた位置でトラスフレーム2に固定されているウインチ4と、を備える。同装置1においては、ウインチ4から延びるワイヤ6が、滑車3に巻き掛けられるとともにトラスフレーム2の上方に位置する作業位置に連結される。そして、複数のトラスフレーム2の上に足場を取り付けた状態で、ウインチ4によりワイヤ6を巻き取ることにより、上記足場が作業位置まで吊り上げられる。滑車3は、その中心軸を支持する支持部材を介してトラスフレーム2に対し固定されている。トラスフレーム2に対する支持部材の固定位置については、トラスフレーム2の長手方向に変更可能とされる。【選択図】図1 |
