The AT40 All Terrain horizontal directional drill features 40,000 pounds of thrust/pullback
The AT40 All Terrain horizontal directional drill features a 160-horsepower (gross) Cummins engine; 40,000 pounds of thrust/pullback; two-speed rotational drive system producing 5,500 lb.-ft. of torque; and an “optimized” two-pipe, all-terrain drilling system that includes a number of patent-pending designs. A 70-gpm, 1,100-psi mud pump delivers fluid to the swivel. The all-terrain system also features a modular design for the RockMaster housing that is adaptable to two drill-bit sizes, and a patented floating-spindle is designed to facilitate replacement. The new housing also features a double-layer seal with high-capacity bearings for increased downhole life, reliability, and reduced maintenance, says the company.
The Direct Pipe system is designed for pipeline applications, combining the processes of micro-tunneling and horizontal directional drilling.
