Articulated mast (1) for a thick-matter delivery installation, especially for a concrete-delivery installation, having at least two mast sections (A, B) which essentially extend along a longitudinal axis (14) and are connected by means of a swivel joint (8) and wherein a (second) mast section (B), relative to an immediately preceding (first) mast section (A), may be swiveled from a folded resting or transport position of the articulated mast (1), in which position this is partially guided laterally past the preceding (first) mast section (A), into an unfolded working position, characterized by the fact that the (second) mast section (B) partially guided by laterally is mounted by its one end to the immediately preceding (first) mast section (A) via an inclined swivel joint axle (131), such that the two mast sections (A, B) in the unfolded working position of the articulated mast (1) are essentially aligned in a vertical reference plane (16) that is plumb with the preceding (first) mast section, and in the folded transport position the guided (second) mast section (B) is deflected from the preceding (first) mast section (A) under a defined angle of spread (.alpha.).
L'invention concerne un mât articulé, en particulier pour installations de transport de béton, qui présente au moins deux parties de mât à extension longitudinale rectiligne reliées l'une à l'autre au moyen d'une articulation de pivotement, une partie de mât pouvant être pivotée par rapport à la partie de mât voisine autour d'un axe d'articulation de pivotement de telle sorte que le mât articulé puisse être amené d'une position rabattue de transport jusque dans une position déployée de travail. Au moins une articulation de pivotement du mât articulé présente un axe oblique d'articulation de pivotement.
