To obtain a scaffold device for replacement of a counterweight capable of improving the efficiency of replacement work of the counterweight.SOLUTION: A scaffold device 7 for replacement of a counterweight comprises a fixed scaffold 701 installed in a hoistway 5 and a variable scaffold 702 provided above the fixed scaffold 701 and attached to a pair of counterweight guide rails 4. The fixed scaffold 701 is arranged in the hoistway 5 so as to be adjacent to a landing 6. The variable scaffold 702 includes a first rotating shaft 709, a supporting part 710, and a scaffold board 711 rotatably provided on the first rotating shaft 709. The scaffold board 711 moves between an installation position provided across the first rotating shaft 709 and the supporting part 710 and facing the fixed scaffold 701 in the height direction and a storage position which is shifted from the installation position by rotating about the first rotating axis 709.SELECTED DRAWING: Figure 3

    【課題】つり合いおもりの取替作業の効率を向上させることができるつり合いおもり取替用足場装置を得る。【解決手段】このつり合いおもり取替用足場装置7は、昇降路5に設置される固定足場701と、固定足場701よりも上方に設けられ、一対のつり合いおもり用ガイドレール4に取り付けられる可変式足場702と、を備え、固定足場701は、乗場6に隣り合うように昇降路5に配置され、可変式足場702は、第1回転軸709と、支持部710と、第1回転軸709に回転可能に設けられる足場板711と、を有し、足場板711は、第1回転軸709を中心に回転することによって、第1回転軸709と支持部710とに渡って設けられ高さ方向において固定足場701に対向する設置位置と、設置位置からずれた位置である収納位置との間で移動する。【選択図】図3
