Dual-wall rods · cyclone sampling · 500 m
A new-generation, efficient, environmentally friendly multi-purpose crawler rig. Dual-wall drill rods return cuttings through the inner tube to a cyclone collector for geological sampling and analysis. Air-lift reverse circulation DTH drilling works across many formations. An independent hydraulic oil cooler keeps the rig running in high outdoor temperatures, while the sliding mast with compensation cylinder clamps to the working face for greater rigidity.
