Product details
Designed around real drilling conditions.
PVTMA’s PVT-DL6 DTH machine for piling is engineered for efficient down-the-hole drilling in open-pit coal, metal, and limestone quarries. Powered by a 220 kW Yuchai turbocharged engine and a Sullivan-Palatek two-stage screw air compressor, this DTH drill rig delivers precise 90–152 mm holes up to 21m deep. Featuring automatic rod handling, a two-stage dry dust removal system, and single-grouser crawler tracks, it ensures reliability, mobility, and eco-friendly operation. Visit www.pvtma.com for pricing and tailored DTH drilling solutions.
Safer rod changes.
An automatic handler carries seven 3 m drill pipes, reducing manual handling around the feed and helping crews maintain a consistent cycle.
Built to control dust.
Two-stage dry dust collection captures cuttings at the source for a cleaner working area and better visibility around the machine.
Stable on broken ground.
Single-grouser tracks, ±10° oscillation and 25° gradeability help the DL6 stay composed on quarry benches and rough access roads.
