Features
All Terrain
- The AT40 All Terrain is designed with an advanced, two-pipe drilling system for industry-leading power to the bit. The enhanced system boosts power and productivity when drilling and steering in hard rock conditions.
- The inner pipe works as a mechanical motor, driving the bit during the bore, and the outer pipe thrusts the bit forward while steering the drill shaft. During backreaming, the outer pipe transmits full machine torque downhole.
- All Terrain technology enables enhanced rock drilling at a low fluid level, decreasing overall jobsite waste, minimizing cleanup and reducing environmental impact.
- The optimized system utilizes true 15-ft length drill pipe, allowing a total of 360 feet of drill pipe to fit onboard for reduced jobsite cycle times.
- Patented All Terrain connection provides a more reliable connection for optimized performance and steering.
- The RockMaster®All Terrain housing has a modular design that allows it to adapt to two different sizes of bits, allowing a 2.875 and 3.5 regular API connection.
- The housing features an industry-exclusive, double-layer seal design with high-capacity bearings to increase downhole life and reliability, which minimizes maintenance and cuts any associated rebuild costs in half.
- A patented, steering-offset design eliminates the need for a universal CV joint, reducing fatigue in shaft and allowing a two-degree bend for more effective and responsive steering in hard rock conditions.
Power
- Equipped with a 160-gross-hp, Tier 4 Cummins® diesel engine, the AT40 All Terrain provides 14 percent more horsepower than competitive models in its class.
- With 40,000 pounds of thrust and pullback, the AT40 All Terrain provides 30 percent more thrust in a more compact unit than competitive models in its class.
- The machine offers an innovative two-speed, rotational drive system, producing 5,500 ft·lb of torque for greater efficiency and uptime.
- The newly updated hydraulic platform utilizes the Ditch Witch-proven technology to provide the most efficient power downhole.
Productivity
- Equipped with a 70-gpm, 1,100-psi mud pump, the AT40 All Terrain has increased fluid course from the mud pump to the swivel, for more downhole flow capabilities.
- The machine includes a patent pending reversible pipe box for added jobsite versatility.
- Patent-pending open-sided vise wrenches on the unit are rotated toward the operator enhancing visibility.
- The drill features a unique add-a-pipe design, which allows operators to manually insert additional sticks of drill pipe when pipe runs out, improving overall productivity.
