摘要: A rock drilling rig has a carrier (1) provided with a service platform (7) arranged on a service boom (6). The service boom has a number of relatively movable boom sections (33, 36). The service platform (7) is connected to the service boom (6) by a parallelogram mechanism (22). The service platform (7) is arranged to the side of a swing plane of the parallelogram mechanism (22) to prevent collisions between the service platform and the service boom.

摘要: A rock drilling rig has a carrier (1) provided with a service platform (7) which is arranged on a boom (6). The carrier (1) is provided with a four link mechanism (8) which is swingable in a plane perpendicular to the longitudinal direction (2) of the carrier. The boom (6) is swingably arranged on one link (9) of the four link mechanism (8) and arranged at a distance from the carrier (1).
