Boart Longyear LM90 Diamond Core Drill
Modular Design
The LM110 was designed as a modular drill rig with a number of options for site-specific customization. This drill is easy to use and upgrade to meet the needs of future drilling projects.
Reliable
The LM90 features a load sensing hydraulic system, proportional controls, a fail-safe rod clamp, built in troubleshooting and a spooling device. These features make the LM90 a highly reliable drill when drilling in harsh conditions.
Driller Safety
The rod handler makes loading rods easier and ensures the drill crew remains away from moving parts during rod tripping.
The LM™90 is the largest Boart Longyear underground diamond coring rig and is suited for drilling deep holes. Equipped with a 29,000-lb feed frame, this drill provides high pullback force as well as a relatively quick rod-handling rate. The feed cylinder is reversible for increased up-hole drilling capacity.
The rig is modular in design with a number of options which make it easier to tailor to specific needs and to upgrade when requirements change. With the assistance of a positioner and a turntable the drill is capable of drilling holes in all angles from vertically up to vertically down. The drill uses an electric motor to power the hydraulics on the machine.
DA Smith's LM90 has been upgraded from a 120 hp motor to an LM110 150 hp motor for increased capacity.
