Abstract

L'invention est relative à une flèche support de brise-roche hydraulique adaptable à la tourelle d'un excavateur. La dite flèche comprend une préflèche 2 mobile par vérin 25, articulée sur la tourelle 3 d'un excavateur 1, un balancier 7 articulé en son extrémité 6 à l'extrémité de la préflèche 2 tandis qu'en l'extrémité 8 du balancier s'articule et est maintenu le brise-roche 9 relié à un vérin d'équipement 20 permettant de le placer selon le travail à effectuer, la position du balancier 7 étant engendrée par un vérin 22. La flèche objet de l'invention peut être utilisée pour supporter différentes sortes d'outils adaptables dont la position en l'extrémité du balancier peut varier ou être fixe.
