Abstract

L'invention concerne une pompe à béton mobile comprenant un dispositif stabilisateur (38) fixé au châssis. Le dispositif stabilisateur (38) comporte au moins deux caissons (54, 6) de bras de stabilisation agencés fixement par rapport au châssis (12) ou de manière à pouvoir pivoter autour d'un axe de pivotement vertical et respectivement un bras télescopique (70) guidé mobile dans les caissons (54, 56) de bras de stabilisation et portant à son extrémité libre une béquille de stabilisation (40). Chaque bras télescopique (70) comprend une courroie supérieure (76) appliquée contre une surface de stabilisation et de guidage (74) située à l'intérieur du caisson de bras de stabilisation (54, 56) associé. Une particularité de l'invention réside dans le fait que la surface de stabilisation et de guidage (74) du caisson (54, 56) de bras de stabilisation et la courroie supérieure (76) du bras télescopique (70) comprennent respectivement au moins deux parties de guidage (74', 74'', 76', 76'') qui forment ensemble un angle en coupe transversale, qui s'emboîtent de manière complémentaire et qui sont appliquées l'une contre l'autre en étant mobiles dans la direction télescopique.
