LIFTING AND LOWERING MOVABLE SCAFFOLD
To provide a lifting and lowering movable scaffold that can be applied to maintenance work for bridge across railroads having a short separation distance from a trolley line and easily move in a ridge direction of the bridge across railroads by avoiding an overhead line such as the trolley line, and allows passage on the bridge across railroads during the maintenance work for the bridge across railroads without requiring assembly and removal for each operation day.SOLUTION: A lifting and lowering movable scaffold has a pair of right and left rails installed along both edges of a road surface of bridge across railroads (pedestrian bridge), a pair of right and left lower movable mechanisms 3 travelling on the pair of right and left rails, a pair of right and left masts 2a erected on the lower movable mechanisms 3, a pair of right and left lifting and lowering mechanisms 4 that moves up and down along the masts 2a, a beam 2b connecting the pair of right and left lifting and lowering mechanisms 4, 4 with each other, and a pair of horizontally movable mechanisms 5, 5 that is suspended from and supported by each lifting and lowering mechanism 4 of the pair of lifting and lowering mechanisms 4, 4 and can horizontally move below the bridge across railroads (pedestrian bridge). The beam 2b is installed at a height allowing people to pass on the road surface of the bridge across railroads (pedestrian bridge Pb) even when the lifting and lowering mechanism 4 is located at a lowest height.SELECTED DRAWING: Figure 1
【課題】トロリー線との離間距離が小さい跨線橋のメンテナンス作業にも適用でき、トロリー線などの架空線をかわして跨線橋の桁行方向の移動が容易で、跨線橋のメンテナンス作業中も跨線橋の通行が可能で作業日ごとの組み払しが必要ない移動昇降式足場を提供する。【解決手段】跨線橋（歩道橋）の路面上の両縁沿いに設置された左右一対のレールと、左右一対のレール上を走行する左右一対の下部移動機構３と、下部移動機構３上に立設された左右一対のマスト２ａと、マスト２ａに沿って昇降動作を行う左右一対の昇降機構４と、左右一対の昇降機構４，４同士を連結するビーム２ｂと、一対の昇降機構４，４の各昇降機構４に吊り下げ支持されて跨線橋（歩道橋）の下方で水平移動可能な左右一対の水平移動機構５，５を備え、ビーム２ｂを、昇降機構４が最低高さにある状態でも跨線橋（歩道橋）の路面上を人が通行可能な高さに架け渡す。【選択図】図１
