DISMANTLING/REMOVAL METHOD OF MOVING WORKING VEHICLE AND MOVING WORKING VEHICLE
PROBLEM TO BE SOLVED: To provide a dismantling/removal method of a moving working vehicle which eliminates a retreat process up to the vicinity of a bridge pier, and the moving working vehicle.SOLUTION: In a dismantling/removal method of a moving working vehicle, the working vehicle comprises: a moving pedestal part 3 which is movable in a bridge axial direction on a bridge girder 102; and a suspension structure 5 having a pair of suspension materials 13a, 13b which extend downward from the moving pedestal part 3, and are arranged at both sides of the bridge girder 102 while sandwiching it therebetween, and lateral beams 15 which extend in a bridge axis orthogonal direction at a lower part of the bridge girder 102, and are suspended by a pair of the suspension materials 13a, 13b. The suspension structure is supported by the moving pedestal part 3. The dismantling/removal method comprises: a structure dividing process for dividing the suspension structure 5 into two pieces, and bringing divided portions of the suspension structure 5 into states that the portions are independently suspended to the moving pedestal part 3 one by one; and a removal process for removing the portions of the suspension structure 5 after the structure dividing process from the moving pedestal part 3.SELECTED DRAWING: Figure 6
【課題】移動作業車の解体撤去時において、橋脚近傍までの後退工程を省略する移動作業車の解体撤去方法及び移動作業車を提供する。【解決手段】移動作業車の解体撤去方法において、移動作業車は、橋桁１０２の上で橋軸方向に移動可能な移動台座部３と、移動台座部３から下方に延在し橋桁１０２を間に挟んで両側に配置された一対の吊材１３ａ，１３ｂと、橋桁１０２の下方で橋軸直角方向に延在し一対の吊材１３ａ，１３ｂによって吊下げ支持される横梁１５と、を有し移動台座部３で支持される吊下構造体５と、を備えており、吊下構造体５を二分割し、分割された吊下構造体５の各部分が独立して一つずつ移動台座部３に吊下げ支持された状態とする構造体分割工程と、構造体分割工程の後、吊下構造体５の各部分を移動台座部３から撤去する撤去工程と、を備える。【選択図】図６
