Abstract (en)
[origin: DE4233171A1] The invention concerns a five-arm concrete-distribution rig (20) mounted on a vehicle. Arms (1, 2 and 3) can be folded together by pivoting in opposite directions about hinged joints (B and C) , which are capable of pivoting through approximately 180 DEG , to form a "Z". In order to make it possible to supply concrete through several hoses in parallel, to upper storeys and over obstacles, the invention proposes that arms (3, 4 and 5) can be folded together by pivoting in the same direction about joints (D and E), which are capable of pivoting through approximately 270 DEG , to bring them up against arms (2, and 3) in the vicinity of hinged joint (C).
