ALL GT SERIES DOUBLE HEAD RIGS ARE FITTED WITH EURODRILL HEADS AS STANDARD, WIDELY ACCEPTED AS THE BEST ON THE MARKET
ACHIEVE NEW STANDARDS IN PRODUCTIVITY & CREW SAFETY
Our rigs consistently set new records for productivity, with customers typically achieving 30% – 50% higher productivity than their existing fleet from day one!
We provide evidence with videos where you can literally count the rods drilling down at speed, and see the ease of drill string removal – no more driller hassle or fatigue when needing to change a drill bit mid-borehole due to changes in complex geology!
All rigs feature robust, reliable, and safe ‘hands-free’ rod handling systems, allowing for efficient operation by a single driller, freeing up time and crew resources for other site tasks.
Our rigs come with class-leading, high specifications as standard, with a choice of ‘included‘ features to tailor the rig to your specific needs and drilling methods.
They are fitted with dual mud pumps with triplex piston, centrifugal, or a combination of both for flexibility and redundancy, ensuring you can maintain the necessary pressures and flush to keep on drilling.
We offer a range of Cummins and Doosan engines, matched for power, fuel efficiency, and quiet operation. These engines can supply mud pumps and multiple auxiliary hydraulics for pit pumps, grouters, and more, without compromising drilling capability.
Need some input, insights and advice in determining what would be the best rig for your operation, don’t hesitate to contact us.
