CA 2501215

The invention concerns a mobile concrete pump comprising a building frame (22) arranged on the structure (12) of a truck chassis (10) and serves to maintain a supporting device (38), a core pump (24) and functional units which form a distribution mast (36). The building frame (22) comprises two longitudinal side members (50) mutually spaced apart by a free space (52) and resting on said chassis structure (12). Said mobile concrete pump further comprises a driving assembly (42) for actuating the functional units, which are arranged with the core pump (24) in the free space zone (52) located between the two longitudinal side members (50). The invention aims at providing a mobile concrete pump whereof the building frame (22) can be easily mounted and dismounted. Therefore, said building frame (22) comprises a floating bearing (54) which links said side members across the free space, as well as a fixed bearing (56) arranged at the rear end of the building frame and serving to support releasably the core pump which is pre-assembled in modular manner. The building frame further comprises mounting means (62) designed to support releasably supporting carrier frames (48) of different sizes which link said side members across the free space (52) and which may be equipped in modular manner with various driving subassemblies (42).

L'invention concerne une pompe à béton mobile comprenant un bâti de construction (22) qui peut être disposé sur le cadre (12) d'un châssis de camion (10) et sert à soutenir un dispositif de support (38), une pompe à noyau (24) ainsi que des unités fonctionnelles qui forment un mât distributeur (36). Le bâti de construction (22) comporte deux longerons longitudinaux (50) espacés l'un de l'autre par un espace libre (52) et reposant sur ledit cadre (12) de châssis. Cette pompe à béton mobile comprend également un ensemble entraînement (42) servant à actionner les unités fonctionnelles, qui sont disposées avec la pompe à noyau (24) dans la zone de l'espace libre (52) située entre les deux longerons longitudinaux (50). L'objectif de cette invention est de concevoir une pompe à béton mobile dont le bâti de construction (22) est facilement montable et démontable. A cet effet, ledit bâti de construction (22) comprend un point d'appui flottant (54) qui relie lesdits longerons à travers l'espace libre, ainsi qu'un point d'appui fixe (56) disposé à l'extrémité arrière du bâti de construction et servant à supporter de manière libérable la pompe à noyau qui est pré-assemblée de manière modulaire. Le bâti de construction comporte en outre des moyens de montage (62) conçus pour supporter de manière libérable des cadres porteurs (48) de différentes tailles qui relient lesdits longerons à travers l'espace libre (52) et qui peuvent être équipés de manière modulaire de divers ensembles entraînement (42).
