COMPACT

Equipped with a 400 Series feed frame and a compact positioner and turntable, the LM55 is easy to transport and set up in tight situations and can drill holes in a full range of angles.

PRODUCTIVE

Equipped with a 40 kN feed frame, the LM55 drill provides high pullback force and a relatively quick rod-handling rate. The feed frame is available in two different sizes to suit a variety of operating conditions.

RELIABLE

With a design proven over the last 20 years in the field, the LM55 is manufactured with quality materials and components. The simplicity of the design makes the machine easy to operate and maintain under tough conditions.

MODULAR DESIGN

The LM55 was designed as a modular drill rig with a number of options for site-specific customization. This drill is easy to operate and upgrade to meet the needs of future drilling projects.

DRILLING APPLICATION

The LM55 is capable of both wireline and conventional coring.

Features

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

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

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.

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