Abstract

L'invention concerne un engin de bétonnage qui comprend une tour rotative (16) tournant autour d'un axe vertical (14) sur un châssis (10), un mât de distribution (18) monté rotatif autour d'un axe horizontal (20) sur la tour rotative (16) et présentant au moins deux flèches (24, 24', 24', 24''') se déplaçant l'une par rapport à l'autre, un bras de distribution (26) articulé à l'extrémité libre du mât de distribution (18) et une conduite d'alimentation (32, 32') acheminant le béton, qui s'étend le long du mât de distribution (18) entre la tour rotative (16) et le bras de distribution (26). Afin de pouvoir utiliser cet engin de bétonnage également sur des chantiers de faible hauteur situés dans des tunnels, le mât de distribution (18) comprend au moins deux flèches (24, 24', 24', 24''') téléscopiques dans le sens de la longueur, tandis que le bras de distribution (26) est monté sur le mât de distribution de manière à tourner autour d'un axe transversal (30) perpendiculaire à l'axe télescopique et autour d'un axe longitudinal (28) qui est perpendiculaire à l'axe transversal. La conduite d'alimentation (32, 32') qui se présente au moins en partie sous forme de tuyau flexible est enroulable automatiquement autour d'un tambour enroule-tuyau (38) et en est déroulable en fonction de l'extension télescopique du mât de distribution (18).
