LM-90 BOART LONGYEAR DCI UNDERGROUND RIG

MODULAR DESIGN

The LM90 was designed as a modular drill rig with a number of options for site-specific customisation. 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 is added to the CDHD LM90, which greatly increases driller safety. The rod handler makes loading rods easier and ensures they remain away from moving parts during rod tripping.

DE-712 HEAVY DUTY CORE RIG

LM-90 BOART LONGYEAR DCI UNDERGROUND RIG

The DE-712 small footprint and remote travel operations enabled CDHD to set up and complete programs successfully with minimal impact to the surrounding areas.

HQ3 600m

PQ3 200m

Key Features - LM-90 BOART LONGYEAR DCI UNDERGROUND RIG

Reversible Feed Cylinder

Semi-Automated Rod Handling

The feed cylinder is reversible which increases up-hole drilling capacity.

Semi-Automated Rod Handling

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

High Torgue Breakout

Semi-Automated Rod Handling

High Torgue Breakout

Automated high torque breakout device breaks most rod joints automatically.

Fail Safe Rod Clamp

Semi-Automated Rod Handling

High Torgue Breakout

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

Load Sensing Hydraulics

Direct Coupled Feed Frame

Load Sensing Hydraulics

Load sensing hydraulics maximize efficiency and reduce heat.

Proportional Controls

Direct Coupled Feed Frame

Load Sensing Hydraulics

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

Direct Coupled Feed Frame

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

Key Features - DE-712 HEAVY DUTY CORE RIG

Built for Exploration

Powerful Diesel Engine

Built for Exploration

Suitable for directional drilling and geotechnical drilling. This rig features a capacity of 1,200m depth in N size. The configuration makes it easy to transport across sites. It's open and accessible design makes service and maintenance tasks fast and simple.

Heavy-Duty Frame

Powerful Diesel Engine

Built for Exploration

With a heavy-duty frame and a robust design, the DE-712 is a space efficient drill rig featuring a robust drill mast supported by a strong main hoist with a failsafe brake mechanism designed for angles between vertical and 45°.

Powerful Diesel Engine

Equipped with a powerful diesel engine, water pump and highly efficient hydraulic system this rig is easy to learn and simple to operate while its robust and precisely engineered design has proven its durability even in the toughest working environments.

Operator Safety

Powerful Diesel Engine

Operator safety has always been paramount and its clear in the design of the DE-712 which features a standard automatic fire suppression system and rod spin guard which protects the operator from the rotating rod string.
