Abstract (en)
[origin: WO2018206702A1] The invention relates to a distribution boom (2) for a concrete pump (1) and to a mobile concrete pump (1) comprising a corresponding distribution boom (2). The distribution boom (2) for a concrete pump (1) comprises at least a first and a second boom arm (4', 4''), wherein the first and the second boom arm (4', 4'') are connected to each other via a joint (5) and can be pivoted relative to each other about a pivot axis (92) via the joint (5), and wherein a concrete delivery line (9', 9'') is provided along the boom arms (4). The joint (5) connects the first and the second boom arm (4', 4'') so that they are offset to each other in the axial direction of the pivot axis (92) such that the load-bearing structures of each of the two boom arms (4', 4'') intersect a separating plane (90) running perpendicularly to the pivot axis (92) between the first and the second boom arm (4', 4'') only in the joint (5), wherein a hydraulic cylinder (21, 21') is arranged on one boom arm (4', 4''), said hydraulic cylinder being connected via one or more coupling rods (22) to the other boom arm (4'', 4') such that the hydraulic cylinder (21, 21') can effect a pivoting movement of the two boom arms (4', 4'') relative to each other about the pivot axis (92) of the joint (5). The mobile concrete pump (1) comprises a corresponding distribution boom (2).
