Abstract (en)
[origin: WO2018162453A1] The invention relates to a boom system (10) for a concrete-delivery device, said system being formed by a plurality of booms (A1, A2, A3) which are pivotably interconnected and each of which has at least one boom (A1, A3) with a recess (12, 14) along its length, said recess being designed such that, when the boom system (10) is in a retracted position, the recess can receive an adjacent boom (A2) having a narrower cross-section.
