Sandvik DB331 is a mobile drill-and-charge unit with integrated mechanized drilling and explosive charging functions. The rig is based on a self-contained diesel hydraulic platform, with an on-board water tank and large compressor for air-mist flushing. A compact feed and efficient Sandvik RD314 rock drill enable easy positioning and fast drilling in confined spaces, such as inside a drawpoint.

Sandvik DB311 is a versatile secondary breaking unit designed to reduce large boulders and improve the ore flow in mass mining operations. The rig is a self-contained diesel-hydraulic carrier with on-board water tank and large air compressor for air-mist flushing. A robust telescopic boom with double rotation actuators and compact feed enables easy positioning within confined spaces at drawpoints, while the high-frequency rock drill enables fast penetration rates.

Sandvik DB120 is a completely self-contained secondary breaking unit for splitting oversized boulders. Thanks to its compact size and agile carrier, this drill rig is an excellent choice when space is an issue. Drill-split operations can be controlled from a safe distance using a radio remote control panel. A major benefit of this breaking method is a vibration-free working environment with low dust levels, since explosives are not needed.
