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 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 1 for maintenance work for bridge across railroads (pedestrian bridge Pb) installed above a trolley line TL has a pair of right and left rails L1 installed along both edges of the bridge across railroads (pedestrian bridge Pb), a lower movable mechanism 2 travelling on the pair of right and left rails L1, a lifting and lowering mechanism 3 that is supported by the lower movable mechanism 2 and moves up and down, and a pair of right and left horizontally movable mechanisms 4 that is suspended from and supported by the lifting and lowering mechanism 3 and horizontally moves along the trolley line TL to open and close with respect to the lifting and lowering mechanism. The lower movable mechanism 2 has a lower frame 20 formed by assembling steel materials. The lifting and lowering mechanism 3 moves up and down at a position higher than the lower frame 20 of the lower movable mechanism 2 and installs the lower frame 20 at a height allowing people to pass on a rood surface of the bridge across railroads (pedestrian bridge Pb).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、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】トロリー線ＴＬの上空に架設された跨線橋（歩道橋Ｐｂ）のメンテナンス作業をするための移動昇降式足場１において、跨線橋（歩道橋Ｐｂ）の両縁沿いに設置された左右一対のレールＬ１と、左右一対のレールＬ１上を走行する下部移動機構２と、下部移動機構２に支持されて昇降動作を行う昇降機構３と、昇降機構３に吊り下げ支持されて、トロリー線ＴＬに沿って水平移動して前記昇降機構に対して開閉する左右一対の水平移動機構４を備え、下部移動機構２は、鋼材が組み合わされた下部フレーム２０を有し、昇降機構３は、下部移動機構２の下部フレーム２０より高い位置で昇降し、下部フレーム２０を、跨線橋（歩道橋Ｐｂ）の路面上を人が通行可能な高さに架け渡す。【選択図】図１
