LM30 Underground Core Drill Technical Overview Brochure

LM™ 30 Technical Data Sheet June 2011 Modular Core Drill ® Page 1 of 5 Boart Longyear is constantly striving to improve its products and must therefore, reserve the right to change designs, materials, specifications and price without notice. Copyright © 2009 BOART LONGYEAR PRODUCT OVERVIEW The LM™ 30 Modular Core Drill has been developed for ease of use in tight situations and locations where mobility and quick setup time are important. Size and weight were the prime concerns when developing this small, lightweight drill rig. FEATURES: • PLC control system, which includes EPROM protection • 400 series feed frame • Auto break out • 37kW Power Pack • Spring close foot clamp • 360° turntable • Dumping feed frame • Regen circuit to ensure feed speed is maintained. DRILLING DEPTH GUIDELINES The figures in these tables have been calculated, based on field experiences, and may be reasonably expected. Actual drilling capacity will depend on in-hole tools, conditions, drilling techniques and equipment used. Depth ratings include allowances for breaking of the core (rock strength 10MPa). Down hole conditions may result in depth capacity variations.
