  • Spacious, heated/air conditioned and pressurized cab

The DM30 is a crawler mounted, hydraulic tophead drive, multi-pass rotary drilling rig specifically designed for production blasthole drilling to depths of 90 ft (27.4 m) with a 30 ft (9.1 m) drill pipe change. An optional 4-rod carousel supports drilling to depths of 150 ft (45.7 m). Nominal diameter is 5 in to 6¾ in (127 to 171 mm). The DM30 generates a bit load force of up to 30,000 lbf (133 kN). An angle-drilling option is also available. Utilizing a diesel engine to drive the air compressor and hydraulic system, the DM30 can be configured for low pressure rotary or high pressure DTH drilling.
