Product overview

High productivity in a two-metre machine.

The DJ18 is designed for compact launch conditions without sacrificing capability. Separate hydraulic circuits allow maximum torque and maximum thrust or pullback to operate together.

  • Machine length of approximately 2.00 metres
  • Pit- or surface-launched modular configuration
  • Up to 95 l/min drilling-fluid volume and 70 bar pressure
  • ADBS II drill-sensor compatibility
Range & configuration

A modular system around the machine.

Plan the pit frame, hydraulic power pack, mixing and pumping station, rods and tooling as one complete setup.
