Abstract (en)
[origin: US2004108003A1] A distribution device for dense substances, especially concrete, with a distribution boom carrying a concrete-conveyance conduit, with at least one telescopic boom section (4) consisting of a first telescope component and a second telescope component (6) that can be extended with respect to this first component, as well as at least one reinforcement beam that is arranged on one of the telescope components and carries a section of the concrete-conveyance conduit, wherein a section of the concrete-conveyance conduit in the region of the telescopic boom section consists of a flexible hose with a compensation loop to accommodate the extension movement of the telescope or of at least one scissor-type conduit assembly made up of swivel elements connected to each other in such a manner that the swivel elements in the two terminal positions of the telescopic boom section are substantially arranged in a crossover position and, together with the articulated joints that interconnect them, move past each other during the extension and retraction of the telescopic boom section, is characterized in that the reinforcement beam that carries a section of the concrete-conveyance conduit in the region of the telescopic boom section has one of its ends connected to the extensible (second) telescope component and its other end connected to the relatively immobile (first) telescope component.
