For gallery mine development in cross sections from 12 up to 18 m2 in mining projects, the crawler-mounted boring loader HBL is able to realize load works and drilling works for blasting also with a single machine.
The semi-automatic changeable devices only need a deposit frame to change between drill rig and shovel. Because of quick couplings in the hydraulic system, the change between the drill rig and the shovel only takes a few minutes.
The drilling unit has a hydraulic hammer for percussive drilling and has been constructed for the preparation of blast hole and anchor drillings.
