AT40 All Terrain Directional Drill

Description

To enhance utility contractors’ efficiency while drilling and steering in hard rock, Ditch Witch has released the AT40 All Terrain horizontal directional drill (HDD). The machine features an advanced, two-pipe All Terrain drilling system that provides 33% more torque than competitive units.

 

The newly optimized All Terrain drilling system includes multiple patent-pending designs that improve downhole operation. An inner-rod design provides a flush system that improves tool-joint durability and steering in hard rock conditions. To further improve steering and optimize fluid flow, a reliable All Terrain connection reduces the risk of collar damage.

 

The All Terrain system also features an enhanced reliable RockMaster housing for improved longevity and reduced maintenance. The modular design makes the housing adaptable to two different sizes of drill bit, allowing a 2.875 and 3.5 regular api connection. And, a patented floating-spindle design makes it easier and more cost effective to replace. The new housing also features an industry-exclusive, double-layer seal with high-capacity bearings for increased downhole life, superior reliability and minimal maintenance. This design feature increases service time intervals – time intervals are doubled compared to previous models.

 

The AT40 All Terrain directional drill is available with durable pipe options to meet all unique jobsites, including the patent-pending All Terrain Flush, Power Pipe HD Fluid Miser II, Power Pipe HD Unlined and Forged HIWS1 pipes.

 

Further enhancing productivity and providing best-in-class power, the new All Terrain drill leverages the same next-generation features of the standard JT40 model. A 160-gross-hp, Tier 4 Cummins® diesel engine offers 40,000 pounds of thrust and pullback. Improved drilling efficiency is provided by a two-speed, rotational drive system that produces 5,500 ft-lb of torque. The drill is also equipped with a 70-gpm, 1,100-psi mud pump to increase fluid flow from the pump to the swivel.
