摘要

: Device for lifting and alignment of nets in rock reinforcement. The device comprises a net alignment unit (4) arranged on a feed beam (3) of a drill rig. The net alignment unit comprises a support (5) being turnable relative to the feed beam and provided with a plate (17) on which two guiding means (6) for a net are arranged at a distance from each other. Through maneuvering the drill rig a net can be lifted and through turning of the support be aligned to parallelism with previously set nets. As an alternative a gear rack (42) movable in a guide (41) is driven by a rotary motor (43) to align the net (46) with other nets. The gear rack is provided with locking means (45) to lock the net to the gear rack.
