Ditch Witch releases next generation directional drill

Ditch Witch releases next generation directional drill

10 October 2017 , 0

Ditch Witch® has released a next generation all terrain horizontal directional drill (HDD), the AT40, which optimises drilling performance in hard rock.

Charles Machine Works Company Ditch Witch’s new machine features an advanced two-pipe drilling system that provides 33 per cent more torque than competitive units and enhances utility contractors’ efficiency while drilling and steering in hard rock.

The new 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, while a reliable connection reduces the risk of collar damage and improves steering and fluid flow.

The system also features enhanced RockMaster housing for improved longevity and reduced maintenance, and the modular design makes the housing adaptable to two different sizes of drill bit, allowing a 2.875 and 3.5 regular API connection.

A patented floating-spindle design makes it easier and more cost effective to replace, and the new housing also features an industry-exclusive, double-layer seal with high-capacity bearings for increased downhole life, reliability and minimal maintenance, allowing service time intervals that are double those of previous models.

The drill leverages the same next-generation features of the standard JT40 model; a 160-gross-hp, Tier 4 Cummins® diesel engine offers 18,144 kg of thrust and pullback, and improved drilling efficiency is provided by a two-speed, rotational drive system that produces 8,184 kg/m of torque.

The drill is also equipped with a 70 gpm, 75.8 bar mud pump to increase fluid flow from the pump to the swivel.

“Maximised drilling performance and more efficient control while steering make the AT40 All Terrain an industry-leading, reliable and powerful machine,” said Ditch Witch Senior Product Manager Horizontal Directional Drills Seth Matthesen.

“The unit not only boosts productivity and power, but leverages next-generation features to provide valuable operational insights and keep operators productive, profitable, and comfortable on each job.”
