A mobile concrete pump including a chassis (10), a rotating gear (14) for a distributing boom which is mounted onto said chassis, a pump assembly and a supporting construction (20). The supporting construction comprises two arc-shaped telescopic guides (32) for arc-shaped support arms (22) that can be retracted into the chassis and extended obliquely outwards in front. The telescopic guides (32) cross each other on different horizontal planes. Their geometric centers of curvature (36) are mirror-symmetrical in relation to the longitudinal axis (38) of the chassis and lie at a lateral distance from the edges of the longitudinal sides outside said chassis (10), behind an imaginary connecting line drawn between the rear ends (42) of the telescopic guides (32). The inventive supporting construction (20) permits large construction stances to be achieved with simple means, said stances also being suitable for distributing booms in the 50 m class.
