OVERHANG ERECTION WORK VEHICLE AND CONSTRUCTION METHOD
To provide an overhang erection work vehicle and construction method having excellent work efficiency and high safety.SOLUTION: An overhang erection work vehicle 1 is used to erect or dismantle a bridge 100. The overhang erection work vehicle 1 comprises a moving work vehicle 3 installed on a bridge girder existing part 104, and a lower work floor 5 suspended and supported by the moving work vehicle 3 at a position below a bridge girder 102. The lower work floor 5 is provided with an opening 25 penetrating vertically. A member of the bridge 100, a temporary bridge material, or machinery is suspended by the moving work vehicle 3 and passed through the opening 25 in the vertical direction to be moved in a raising or lowering manner.SELECTED DRAWING: Figure 2
【課題】作業効率がよく安全性が高い張出架設作業車及び施工方法を提供する。【解決手段】張出架設作業車１は、橋梁１００の架設又は解体に使用される。張出架設作業車１は、橋桁既設部分１０４の上に設置される移動作業車３と、移動作業車３によって橋桁１０２の下方の位置に吊支持される下部作業床５と、を備え、下部作業床５には上下に貫通する開口２５が設けられている。橋梁１００の部材、橋梁の仮設資材、又は機材が、移動作業車３に吊られ開口２５を上下方向に通過して吊上げ移動又は吊下げ移動される。【選択図】図２
