Abstract: The invention relates to an automatic concrete pump with an articulated mast (14) serving as a support for a supply line and with two forward and two backward support extensions (16?,16?,18?,18?) which can be supported on a base platform (32) and which can be lowered from a driving position into a support position, each with a telescopic support leg (30). According to the invention, each support extension comprises one inner support position near to the chassis, and at least one outer support position away from the chassis, which can be freely selected by forming defined support configurations (V,SL,SR,YL,YR,N) for the four support extensions.

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).
