Combination Drill Rig Boosts Performance

High-capacity direct push machine handles tough jobs with its durable undercarriage, hollow stem auger capabilities, and wide-base platform. GH80 hammer drives 2.25-inch and 3.5-inch tooling to greater depths in tougher formations. Need a larger volume soil sample or 2-inch well? Drive 4.5-inch tooling to complete your projects. And with a two-speed hydraulic top head, auger into lithologies not conducive to direct push techniques.

Features & Options

  • 84-inch (2134 mm) probe cylinder stroke allows use of 60-inch (1524 mm) probe rods
  • 40-ton pulling capacity for today’s larger sampling tools and deeper depths
  • Equipped with the five-function CB8 Combo Head
  • Heavy-duty undercarriage has a wider track that carries more weight, adds more torque, reduces ground pressure, and handles greater tool weight
  • Wireless remote control
  • Built-in rotary spindle for concrete drilling, augering, and anchoring
  • Equipped with a hydraulic winch for handling augers and tripping dual tube sampling tools
  • Powered by a four-cylinder, 120 hp, liquid-cooled CAT® turbo diesel engine
  • Hydraulic movement in all three axes allows easy probe alignment with tool string
  • Five auxiliary hydraulic ports provide power for remote equipment
  • Sideshift that allows centerline access of toolstring
  • Hydraulic Rod & Casing pull feature is compatible with 4.25-inch, 3.5-inch, and 2.25-inch Geoprobe® tooling.
  • Integral electronic diagnostic system works to safeguard the unit and help the operator quickly diagnose problems in the field.
  • Rear stabilizing blade compatible with the Geoprobe® drop-rack system
  • Adjustable operator control panel is mounted on a swing arm enabling quick and easy movement to the optimum position for operation.
