Distributor device for unset concrete

Abstract

A distributor device for unset concrete. The distributor device comprises a delivery conduit that can be connected to the pressure outlet ( 78 ) of a concrete pump ( 72 ) on the inlet side and is provided with an outlet part (tube pieces 22, 26, 30 ) that can be moved to a concreting point via a manipulator (hydraulic cylinder 38, 40 ). According to the invention, the outlet part of the delivery conduit is arranged, with the associated manipulator, on a mobile chassis ( 44 ) that is separate from the concrete pump ( 72 ), and of which the inlet side can be connected to the pressure outlet ( 78 ) of the concrete pump( 72 ) by means of an at least partially moveable connecting conduit ( 50 ).
