ROCK DRILLING RIG AND METHOD FOR DOWNHILL DRIVE

摘要

The invention relates to a rock drilling rig and a method for downhill driving of a rock drilling rig. The rock drilling rig (1 ) comprises electric drive equipment (16), the drive motor (M) of which serves as a primary brake in long-term downhill driving. The drive motor thus converts kinetic energy into electric energy, with which an energy storage (B) is charged. To consume surplus electric energy, a hydraulic system (13) or a compressed air system (50) is turned on. A hydraulic pump (34) and a compressor (54) are driven by an electric motor (33, 55).
