Field-tested to prove it can handle the toughest large-diameter projects, the D500x500 is equipped with all the features HDD operators need to get the job done. It drills through almost any ground conditions with 50,000 ft-lb/68,000 Nm of rotational torque and 500,000 lbs/2,224 kN of thrust/pullback.

Features and Benefits

  • Operates efficiently with high-torque, low speed Hagglund hydraulic motors powering the rotary and carriage drives so you can run full torque and full rotary rpm simultaneously.
  • Reduces stress on the motor, because the thrust box bearing-pack assembly is designed to absorb the axial load caused by thrust and pullback.
  • Helps prevent rod wrap or wind-up because its floating vice allows the breakout system to clamp the full rod upsets during breakout of the lower and upper joints.
  • Muscles through difficult ground formations with higher torque than other models.
  • See your Vermeer dealer for comprehensive service and genuine Vermeer replacement parts.
