<P>PROBLEM TO BE SOLVED: To provide a concrete pump vehicle having a boom whose safety is not impaired during installation when the operating speeds of the beams are higher particularly in the state of being folded. <P>SOLUTION: A concrete pump vehicle V includes a boom device B having at least two or more beams 131-134, boom driving means 14 for driving the boom device B, and control means C for driving the boom driving means 14 on the basis of an operation signal from operation means. It further includes detection means Se for detecting the attitudes of the beams. The control means C determines a maximum speed VA of the boom driving means 14 on the basis of the detection result of the detection means Se and drives the boom driving means 14 within the range of the maximum speed VA. <P>COPYRIGHT: (C)2013,JPO&INPIT |
