An arrangement or mounting swing cylinders in a boom for a rock drifting unit, comprising a frame (1), a boom (2) pivotally connected about vertical and horizontal shafts (3, 4), relative to the frame (1), a lift cylinder (5) connected between the frame (1) and the boom (2), a swing cylinder (6) connected between the frame (1) and the boom (2), a support (7) for a feed beam, pivotally connected to the other end of the boom (2) about horizontal and vertical shafts (8, 9), a tilt cylinder (10), connected between the support (7) and the boom (2), and a transverse swing cylinder (11) connected between the support (7) and the boom (2). In the invention the swing cylinder (6) is coupled at an angle (.alpha.), relative to the longitudinal axis of the boom (2), from the frame (1) to the end of the boom (2) vertically downward so that with the boom (2) in the middle of its upper and lower angles of altitude, the swing cylinder (6) is essentially horizontal.
Structure de montage de vérins de pivotement pour un bras de perforatrice de roches, qui comprend un châssis (1), un bras (2) relié pivotant autour d'un arbre vertical et d'un arbre horizontal (3, 4), par rapport au châssis (1), un vérin de levage (5) reliant le châssis (1) et le bras (2), un vérin de pivotement (6) reliant le châssis (1) et le bras (2), un support (7) pour une poutrelle d'avance, relié pivotant à l'autre extrémité du bras (2) autour d'un arbre horizontal et d'un arbre vertical (8, 9), un vérin d'inclinaison (10) reliant le support (7) et le bras (2), et un vérin de pivotement (11) transversal reliant le support (7) et le bras (2). Selon la présente invention, le vérin de pivotement (6) est couplé à un angle alpha par rapport à l'axe longitudinal du bras (2), entre le châssis (1) et l'extrémité du bras (2), verticalement vers le bas, si bien que lorsque le bras (2) se trouve au milieu de ses angles d'élévation supérieur et inférieur, le vérin de pivotement (6) est pratiquement horizontal.
