Equipped with optimized features for large-diameter drilling.

Engineered for reliability, the field-tested D750x900 Navigator® horizontal directional drill is equipped with optimized features for large-diameter drilling. Its penetrating twin Caterpillar C-18 engines produce a maximum of 92,000 ft-lb (124,735.3 Nm) of rotational torque and 750,000 lb (3,336.2 kN) of thrust/pullback.

FEATURES & BENEFITS

HIGHER TORQUE
Muscles through difficult ground formations with higher torque than other models.
HIGH-TORQUE, LOW-SPEED HAGGLUNDS HYDRAULIC MOTORS
Operates efficiently with high-torque, low-speed Hagglunds hydraulic motors that power the rotary and carriage drives so you can run full torque and full rotary rpm simultaneously.
THRUST BOX BEARING-PACK ASSEMBLY
Reduces stress on motor because the thrust box bearing-pack assembly is designed to absorb the axial load caused by thrust and pullback.
FLOATING VISE
Helps prevent rod wrap or windup because its floating vise allows the breakout system to clamp the full rod upsets during breakout of the lower and upper joints.
