Power Group High on efficiency; low on cost To achieve low cost, high efficiency drilling, your power group configuration is selected to match the needs of your specific geology and site conditions. We have numerous configurations for low pressure rotary drilling or high pressure DTH hammer drilling. Power groups are arranged in-line for easy access, from both sides, to the engine, compressor, hydraulic pumps, plumbing and other components, which translates into safer serviceability and lower maintenance cost. Engines To match your application demands, MD6240 has three choices for engine sizes....

Hydraulic System For efficient flushing of cuttings and dust out of the bore hole, the air compressor delivers the right amount of bailing air based on hole diameter, depth and material density. Air-on-demand control system regulates air intake to match the amount of compressed air being used. For ample capability, our cooler systems are designed to assure unrestricted airflow and reduce excessive operating heat, which extends life of engine, compressor, and hydraulic components. • Rated up to 52° C (125° F) ambient cooling capacity • Split or single cooler • Side by side engine radiator • Charge...

Mast System Strong and sturdy To assure long life, all mast structures are designed with double-cut lacing in high stress areas. There are several application-specific masts to choose from. Mast Height Pipe Length Single Pass Depth Pipe Diameter Pipe Wall Thickness Rotary Drill Head (1) A single, double-acting cylinder, cable pull-down system produces 22 680 kg (50,000 lb) of pull-down force and 22 680 kg (50,000 lb) of hoist force. The cylinder rod is fixed on both ends with a moving barrel, providing high efficiency and reducing feed system wear and maintenance. • One variable displacement...

Angle Drilling The MD6420 can drill in angles up to 25 degrees (in 5 degree increments). Dual mast locks are located under the deck and hydraulically operated dust curtains are available for angle drilling. Pipe Rack Carousel (2) The hydraulically operated carousel-type pipe changer is located outside of the mast structure, and all functions are controlled from a console in operator’s cab, which assures efficient and safe drill string changes and storage. The carousel provides automatic indexing of drill pipes in relation to the rotary head. • Pipe diameter 114-178 mm (4.5-7.0 in) • 12 m (39...

Dust Collection Largest chamber in the industry For efficient dust collection MD6240 has a dust collector rated at 127 m3/min (4,500 ft3/min) and separate water injection system. Both dry and water injection systems can be mounted on the same drill. • Water injection system options: – Three tanks totaling 1271 L (336 gal) mounted under the front deck or – One tank 1514 L (400 gal) mounted on top-deck (mounted in place of Dry Dust Collector) Dust Curtain With the largest dust chamber in the industry, the MD6240 has a total enclosed area of 4.2 m2 (45.14 ft2) and is surrounded by heavy rubber curtains....

Fully Equipped Cab For operator safety and comfort Safe and Effortless Operation To limit operator fatigue the MD6240 controls are ergonomic.
