Abstract (en)
[origin: WO2014019885A1] A concrete dispensing boom for stationary and mobile concrete pumps has a plurality of boom arms (22), connected to one another at joints, and a concrete conveying line consisting of a plurality of pipe segments (30) preferably connected to one another in an articulated manner via pipe bends and rotary couplings. Said pipe segments run along the individual boom arms (22) and are attached to these boom arms. At least one of the boom arms (22) has a hollow chamber profile which has at least two hollow chambers (24, 26) separated from one another by a separating wall (38), at least one of which chambers is a closed chamber (24) and one (26) is open at the periphery. The pipe segment (30) allocated to the boom arm (22) concerned is disposed on the opening side outside, partially inside or inside the open hollow chamber (26).
