欠点がある。Conventionally, in a three-stage retractable boom device equipped with a concrete transfer pipe, a hydraulic cylinder for operating the 27th boom was installed between the upper surface of the first boom A and the lower surface of the second boom B, as shown in FIG. C has a stacked structure in which the third boom operating hydraulic cylinder E is installed between the upper surface of the second boom B and the lower surface of the third boom D, so when it is mounted on a car, the ground clearance will inevitably be high. However, it has the disadvantage of poor running stability.

る。As described above, when the refracting boom is stored in the traveling position, the second boom actuating hydraulic cylinder and the third boom actuating hydraulic cylinder are moved back and forth in the gap between the opposing surfaces with the 17th boom. As a result, there is no need to provide a gap between the facing surfaces of the second boom and the third boom to install the hydraulic cylinder for boom operation, which is required in the past. When installed, the ground clearance can be lowered and driving stability can be further improved.
さらに各ブーム及び油圧シリンダを上下方向に重ねたこ
