The magazine (3) including the drill bit, is pivotably mounted on at least one arm (6) so that the components can be guided into a position coaxial with the rotation axis (8) for the mechanism (2) used to rotate the drill rod (14). The drill rod components are received by a rotatable holder in the magazine. - The rock drilling machine comprises a feed beam (1), a rotation mechanism moved backwards and forwards along the beam in order to rotate the drill rod, and a magazine mounted on the beam for housing the drill rod components. |
