Sandvik DQ240R is hydraulically operated, excavator mounted line drilling unit for dimen-sional stone quarries.
Sandvik HL1560ST is a hydraulic top hammer rock drilldesigned for DL411 and DL421 underground longholedrills. It is capable of drilling Ø89 - 127 mm holes up to 54meters in depth, using T51 MF-rods or ST58 and ST68tube rods.
Sandvik HL300 hydraulic rock drill is designed for longhole production drilling on surface and rock bolting in hard rock bolting in underground hard rock mines. It is also used in light tunneling rigs.
Sandvik HL650 hydraulic rock drill is designed for drilling 64– 102 mm diameter holes. Sandvik HL650 is used in Sandvik surface drill rigs.
Sandvik RD314 high-frequency hydraulic rock drill is designed for bolting and face drilling rigs.
Sandvik DB311 is a Secondary Breaking Unit (SBU) for rock boulders reduction and ore facilitation in mass mining methods, enabling fast recovery of full mining production when large rock boulders cause draw points blockages.
Sandvik DD211L is a low-profile single-boom electrohydraulic drill designed to work in excavations with headroom as low as 1.7 meters. The robust universal boom has a large optimum shaped coverage, 360-degrees rotation and full automatic parallelism for fast and easy face drilling. The boom can also be used for cross-cutting. The hose layout is specifically designed to maximize protection in low headings.
Sandvik DD311 is a single-boom electro-hydraulic jumbo for fast and accurate drilling in drifting and tunneling of 40 m² cross sections. The hydraulic controls enable accurate and efficient drilling performance.
Sandvik DD321 is a compact two-boom jumbo for demanding conditions and multiple applications. The jumbo is capable of face drilling, cross-cut drilling and bolt hole drilling.
Sandvik DL230L is a low-profile single-boom electro-hydraulic production drilling jumbo designed to work in excavations with headroom as low as 1.7 meters. Sandvik DL230L is capable of drilling several lines of parallel holes, up, down and horizontally, as deep as 23 meters.
