The LM75 drill provides high pullback force and a fast rod handling rate. The feed frame is available in two sizes to suit a variety of operating conditions.
The LM75 features a load sensing hydraulic system, proportional controls, a fail-safe rod clamp, built in troubleshooting and a spooling device. These features make the LM75 a highly reliable drill when drilling in harsh conditions.
The LM75 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.
An optional patented rod handler can be added to the LM75, which greatly increases driller safety. The rod handler makes loading rods easier and ensures they remain away from moving parts during rod tripping.
The LM75 is capable of both wireline and conventional coring.
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.
6. SEMI-AUTOMATED ROD HANDLING (OPTIONAL)
Semi-automated rod handler (optional) makes handling of rods safer and easier.
7. ELECTRONIC CONTROLS UPGRADABLE (Optional DCi)
Upgrade the controls system with the DCi for improved safety and productivity. The DCi offers unattended drilling and semi-automated functions and operates both the rod handler and drill from a single control panel.
