Abstract (en)
[origin: WO2010026296A1] The invention relates to a rock drilling rig and a method of turning a drilling boom of a rock drilling rig. A carrier (2) of the rock drilling rig comprises a lower body (3) and,arranged on top of it,an upper body (4) which may be turned by a turning device (20). A boom (13) is attached to the upper body, and the boom (13) is turned by turning the upper body. Further, the boom is arranged turnably in the upper body, whereby a turning angle (K1) of the upper body with respect to the lower body and a turning angle (K2) of the boom with respect to the upper body determine a largest turning angle (K) of the boom.
