LMPQ UNDERGROUND CORING DRILL RIG

LMPQ UNDERGROUND CORING DRILL RIG

The LM PQ builds off the already popular LM110 and Nitro-Chuck™ platforms with the addition of a  PQ drill head. The drill allows a 50% increase in drilling depth for NQ-size drill bits. As with all LM drills, the rig can be operated remotely via the DCi™ (Drill Control Interface) and supplied with a rod handler for enhanced safety. This drastically reduces the driller’s exposure to hand injuries, one of the drilling operator’s biggest risks. When paired together, drillers can use semi-autonomous drill routines during breaks and shift changes, which have been found to increase productivity by up to 14%.

PROPORTIONAL CONTROLS

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

SEMI-AUTOMATED ROD HANDLING (OPTIONAL)

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

DIRECT COUPLED FEED FRAME

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

LOAD SENSING HYDRAULICS

Load sensing hydraulics maximize efficiency and reduce heat.

FAIL SAFE ROD CLAMP

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