<P>PROBLEM TO BE SOLVED: To provide a concrete pump vehicle having a boom capable of inhibiting the forcible abutment of beams on each other resulting in breakage, when folded and stored. <P>SOLUTION: The concrete pump vehicle includes a boom device B having at least one or more beams 131-134, boom driving means 14 for driving the beams 131-134, and control means C for driving the driving means 14 on the basis of an operation signal from operation means R. It further includes an inclination sensor Se (detection means) for detecting the attitudes of the beams 131-134. The control means sets a swing speed to be lower when the derricking angle of the first beam 131 (the base beam) nearest the vehicle body is a predetermined value or smaller. <P>COPYRIGHT: (C)2013,JPO&INPIT |
