MODULAR DESIGN

The LM90 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.

SAFE

An optional patented rod handler can be added to the LM90, which greatly increases driller safety. The rod handler makes loading rods easier and ensures they remain away from moving parts during rod tripping.

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 breakout device breaks most rod joints automatically.

4. FAIL SAFE ROD CLAMP
Hydraulic open and spring close rod clamp results in fail safe operation.

5. LOAD SENSING HYDRAULICS
Load sensing hydraulics maximize efficiency and reduce heat.

6. PROPORTIONAL CONTROLS
Proportional controls and lock levers provide optimum control of rpm and feed.

7. DIRECT COUPLED FEED FRAME
Direct coupled feed frame results in lower maintenance and smoother feed transmission.
