Mechanized drill with explosive charging
Mounted on Sandvik DB331’s charging head, the explosive charging device uses the drill and blast method for fragmenting boulders. The high-frequency rock drill speeds up the drilling process, meaning less exposure under the drawpoint.
Improved visual capacity
Operators can use Sandvik DB331 remotely by accessing the video system, which includes a tablet display, 3D-zoom camera and multiple wide-angle cameras.
Air-mist flushing
The unit features an onboard water tank. Working alongside the large air compressor, operators can air-mist flush to reduce the dust.
