LM™110

MARKETS: Mineral Exploration

The LM™110 is the newest addition to the LM range of underground drills and is designed for drilling even deeper holes, more productively. Powered by a new 110kW power pack, the LM110 offers the greatest depth capacity and functionality.

  • The new 110kW power pack delivers up to 33% more torque to the drill head than a similarly equipped LM™90 delivering increased productivity.
  • The LM110 was designed as a modular drill rig with a number of options for site-specific customization. This drill is easy to upgrade and reduces training requirements for drillers.
  • An optional rod handler can be added to the LM110, which greatly increases driller’s safety. The rod handler makes loading rods easier on drillers and ensures they remain away from moving parts during rod tripping.
  • The LM110 features a load sensing hydraulic system, proportional controls, a fail-safe rod clamp, built in troubleshooting and a spooling device. These features make the LM110 a highly reliable drill when operating in harsh conditions.

LM™90 Features

1. Reversible Feed Cylinder

The feed cylinder is reversible which increases up-hole drilling capacity

2. Semi-automated Rod Handling (Optional)

Semi-automated rod handler (optional) makes handling of rods safer and easier

3. High Torque Breakout

Automated high torque break out device breaks most rod joints automatically

4. Fail Safe Rod Clamp

Hydraulic open and spring close rod clamp results in fail safe operation

Load Sensing Hydraulics

Load sensing hydraulics maximize efficiency and reduce heat

Proportional Controls

Proportional controls and lock levers provide optimum control of rpm and feed

Direct Coupled Feed Frame

Direct coupled feed frame results in lower maintenance and smoother feed transmission
