Product description
The Smart DML is a crawler-mounted, hydraulic tophead-drive rig that's suitable for a variety of multi-pass rotary and DTH drilling applications. It's designed specifically for production blasthole drilling of depths of 175 ft (53.3 m) with a 30 ft (9.1 m) pipe change or 205 ft (62.5 m) with the optional 35 ft (10.7 m) pipe change.
Feed pressure generates a pulldown of up to 60,000 lbf (267 kN), utilizing a diesel engine to drive the air compressor and hydraulic system. The powerful rotary tricone and DTH hammer drill delivers a hole diameter of 5 7/8 in to 10 5/8 in (150 mm to 270 mm) and can achieve a clean hole 32.5 ft (9.9 m) in single-pass applications or depths of up to 205 ft (62.5 m) in multi-pass applications.

Enhanced safety
Built-in safety interlocks and plug-and-play PDM modules eliminate the need for in-cab diagnostics and reduce live work exposure. 360° embedded camera options and Rig Remote Control (RRC) improve visibility and operator distance during setup.
Ease of maintenance
The deck layout on the Smart DM series offers easy access to all major service components. Hydraulic system filters are also mounted externally for accessibility. The integrated A/C system is mounted on the side, so no roof access is required, and the central lubrication manifold streamlines maintenance. To make service even easier, optional ground-level, quick-connect fittings are available for fast fill and evacution of fuel, hydraulic oil, engine coolant, and other fluids.
Operator comfort
The Smart DML features an insulated, air-conditioned, pressurized cab with an adjustable swivel seat and excellent visibility. All operational functions are controlled from the RCS chair control panels, and the ergonomic layout allows operators to instantly switch from drilling to tramming for increased productivity. In addition, the intuitive RCS controls are common across the Smart DM series, making operation easy for drill operators. Plus, with a rating of 80 dBA, the noise inside the cab is kept to a minimum for greater operator comfort.
