ROCK DRILLING RIG AND METHOD FOR TRANSMISSION OF ROCK DRILLING RIG

摘要

The invention relates to a rock drilling rig and to a method for transmission thereof. The rock drilling rig (1) comprises a carriage (2) movable by drive equipment (16) in a mine. The rock drilling rig comprises a hydraulic drilling system (13) for which pressure energy is generated by a hydraulic pump (21). The rock drilling rig is electrically driven and it includes an electric motor (M) which is connected to drive both the drive equipment and the hydraulic drilling system. The mechanical drive transmission included in the drive equipment and the hydraulic pump of the hydraulic drilling system may be connected and disconnected independently of one another by means of clutches (K).
