Abstract

L'invention concerne un mât distributeur qui est conçu pour une pompe à béton fixe ou mobile. Le mât distributeur (10) présente au moins trois bras (23 à 27) pouvant pivoter autour d'axes (28 à 32) parallèles, les uns par rapport aux autres ou par rapport à un chevalet (21) de mât, dans chaque cas, au moyen d'un groupe d'entraînement (34), ainsi qu'une conduite de refoulement (16) alimentée en béton liquide au niveau d'une entrée et guidée par sections par les bras de mât, et qui débouche côté sortie dans un élément de sortie (43, 45) disposé sur le dernier bras de mât (27). Conformément à l'invention, le dernier bras de mât (27) se compose de deux parties (27', 27'') reliées entre elles de manière rigide en un point de séparation (40) et le groupe d'entraînement (34) qui est relié avec l'avant-dernier bras de mât (26) vient en contact avec une première partie de bras (27') aarticulée directement sur l'avant-dernier bras de mât (26). Toujours selon l'invention, il est prévu au moins deux deuxièmes parties de bras (27'') différentes et interchangeables de manière modulaire pouvant être équipées de différents éléments de sortie (43, 45) qui peuvent être raccordés à la conduite de refoulement (16).
