REMOVAL METHOD OF CANTILEVERED OVERHANG WORK VEHICLE

摘要

To provide a removal method of a cantilevered overhang work vehicle which can perform a pull-back operation of the cantilevered overhang work vehicle in an approximately same state, without removing a part of a cross beam of an upper structure or lowering a lower working platform immediately below, and can be easily perform the pull-back operation by merely rearranging small and lightweight components.SOLUTION: Provided is a removal method of a cantilevered overhang work vehicle 2 for removing the cantilevered overhang work vehicle 2 after pulling back the cantilevered overhang work vehicle 2 to a bridge face at a position near a support tower 13 provided in a substantially center part of the bridge after the completion of construction. The cantilevered overhang work vehicle 2 is formed by connecting a pair of cantilevered overhang work vehicle units which are framed in a substantially rectangular shape, and the formed cantilevered overhang work vehicle 2 is mounted on a plurality of rails 14. A lifting preventing roller is engaged with and attached to the inner rail 14 so as to prevent the cantilevered overhang work vehicle units from being overturned in a bridge width direction side.SELECTED DRAWING: Figure 1
