To provide a crane which can be easily installed on a rooftop, and a method for assembling a framework scaffold by which a framework scaffold can be safely assembled using the crane without being affected by the surrounding environment of a building.SOLUTION: A crane comprises: a support member 2 that can be installed on a roof R of a building B; a protruding beam 3 which extends laterally from the support member 2 and a tip of which protrudes outside a wall surface B1 of the building B; a first trolley 7 that has a power source and is provided so as to be able to self-travel along the protruding beam 3; a second trolley 8 that is positioned on an end side of the protruding beam 3 with respect to the first trolley 7 and is provided so as to be able to travel along the protruding beam 3; a drive unit 50 that is held by the first trolley 7 and can raise and lower a tip of a wire 4; and a winch 5 that has a storage unit 51 held by the second trolley 8 and storing the wire 4 raised by the drive unit 50 and supplying the wire 4 to the drive unit 50 when the drive unit 50 lowers the wire 4.SELECTED DRAWING: Figure 1

    【課題】本発明は、屋上に容易に設置可能なクレーン及び、建築物の周囲の環境に左右されずにクレーンを利用して安全に枠組足場を組み立てられる枠組足場の組立方法の提供を目的とする。【解決手段】本発明は、建築物Bの屋上Rに対して設置可能な支持部材2と、支持部材2から横方向に延びて建築物Bの壁面B1より外側に先端側が突出する突出梁3と、動力源を有して突出梁3に沿って自走可能に設けられる第一トロリー7と、第一トロリー7よりも突出梁3の基端側に配置されて突出梁3に沿って走行可能に設けられる第二トロリー8と、第一トロリー7に保持されてワイヤー4の先端を上昇及び下降可能な駆動部50と、第二トロリー8に保持されて駆動部50によって上昇されたワイヤー4を格納するとともに駆動部50がワイヤー4を下降させる際にワイヤー4を駆動部50へ供給する格納部51とを有するウィンチ5とを備える。【選択図】図1
