LM™90

MARKETS: Mineral Exploration

The LM™90 is equipped with a 130kN feed frame for drilling deep holes. It 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.

  • Direct Coupled Feed Frame with 130kN pullback and 1.8 m feed stroke
  • Reversible Feed Cylinder for increased up-hole drilling capacity
  • Standard Power Pack with 90kW electric motor
  • Standard self contained control panel with stand and e-stop
  • Standard Feed Frame Positioner and Turntable (optional)
  • HQ™ high torque (HQ™ optional) rotation unit for deep-hole drilling
  • PQ™ (HQ™ optional) rod clamp for max holding capacity
  • Semi-automated rod handler (option)

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
