Abstract

The invention relates to a rock drilling rig, a method for transfer drive of the rock drilling rig, and a speed controller. The rock drilling rig (1) comprises combustion-engine-free drive equipment (16) which includes a plurality of electric components (K) for implementation of the transfer drive. The control unit (C) of the rock drilling rig includes load monitoring (KV) which monitors the load of the components during the transfer drive. Load monitoring allows the electric driving system to be intentionally overloaded for a period of time limited in advance. A user interface of the control unit comprises a speed controller (50) whose control element (51) has a first control range (53), where operation takes place in the rated load range, and a second control range (54), where operation takes place in the overload range.
