A boom system for a concrete-delivery device includes a plurality of booms which are pivotably interconnected. At least one of the booms has a recess along its length, the recess configured to at least partially receive an adjacent boom when the boom system. is in a retracted position. Side walls of the boom are extended to define the recess in the form of a channel. The recess may have a depth greater than or equal to a height of the adjacent boom so that the adjacent boom is received within the recess when the boom system is in the retracted position. Alternatively, the recess may have a depth less than a height of the adjacent boom so that the adjacent boom is only partially received in the recess when the boom system is in the retracted position.
A boom arm system for a concrete delivery device, where said boom arm system is formed from a plurality of boom arms connected pivotably to one another and of which at least one boom arm in longitudinal extent has a recess which is configured in such a manner that, in a folded-in position of the boom arm system, said recess serves for accommodating an adjacently arranged boom arm having a narrower cross section, wherein the at least one boom arm comprises a pipe holder that projects out and the boom arm having a narrower cross section has a pipe holder that projects out of said recess in the folded-in position of the boom arm system.
