摘要： PURPOSE: To support a boom having a long length and a large quantity of projection by forming the guide member of a beam into substantially the concentric arcuate shape, and deploying it in a state being in contact with a parallel surface in the longitudinal direction of a vehicle frame. CONSTITUTION: A swing boom is mounted on a swing device 11, and guide members 31-34 are fixed on the vehicle so as to guide beams 19-22 to be pulled into the vehicle profile. These guide members 31-34 are formed into substantially the concentric arcuate shape to be arranged in a state of being extended in a space between the longitudinal side surface parts 35, 36 of the vehicle profile and in contact with a parallel surface in the longitudinal direction of the vehicle frame. Furthermore, they are inward forward extended toward the central part of the vehicle frame from the rear parts 35a, 36a in the longitudinal direction of longitudinal directional side surface parts 35, 36, and further extended toward the front parts 35b, 36b. This can allow the beams 19-22 constituting the support frames to be elongated without making a profile of the vehicle.
