Beschreibung
Zusammenfassung:	The invention relates to a concrete pumping vehicle with a concrete pump and a multiple part mast superstructure (2). The mast superstructure (2) comprises at least two mast arms (9, 10) connected in an articulated manner, of which one mast arm (10) may be pivoted relative to the other mast arm (9) by a hydraulic cylinder, the hydraulic cylinder (11) having a cylinder container (12) for accommodating a piston (13), said cylinder container having a base region (18) that is closed, wherein the base region (18) has an outward curved configuration with respect to the cylinder container (12). A bearing ring in the form of an eye part is arranged in the base region (18) of the cylinder container (12), and the eye part is configured to pass through a bearing-bolt pipe (26) of the cylinder container (12). The bearing-bolt pipe (26) is arranged within a volume defined by the base region (18).
