CPT Drill Rigs by Geoprobe®

Reaching Greater Depths

Whether you’re seeking a dedicated CPT drill rig to conduct your penetrometer test or a more versatile CPT drill rig to also conduct other types of drilling applications, our CPT drill rigs are only considered ‘CPT-ready” if they incorporate:

  • Downforce: effectively push CPT with force to execute the work
  • Automatic Head Feed Rate Control: provide a consistent 2cm/sec CPT push rate, meeting ASTM standards
  • Downforce Limit Control: control in the menu of the system display to derate the downforce and observe the pressure being placed on the cone, providing another operator checkpoint (available on the 3126GT, 3100GT, 3230DT, and 2060CPT)

Static Push Platforms
Our dedicated 20-ton capacity CPT drill rig options provide choices between climate-controlled cabin crawlers and nimble skid-steer or drill rig mounted presses.

Anchoring Platforms
Our combination CPT drill rig platform options are able to take the drill head close to the ground, often reaching greater depths than conventional rigs by leaving less rod in the air. Multiple CPT drill rig anchoring options provide the flexibility desired to reach depth depending on the site conditions.

With rig service shops in Pennsylvania, Kansas, and Florida, you’ll have industry-leading CPT drill rig service support nearby for your routine maintenance or more in-depth rig remounting and refurbishment work - keeping your CPT drill rig in the field earning dollars. Our service technicians are backed by our team of engineers to ensure solutions not bandaids to issues. And our production processes mean your CPT drill rig is constructed consistently and tested thoroughly to ensure easier service support.

Engineered with easy, fast, safe penetrometer testing in mind, investing in a Geoprobe® CPT drill rig boosts sampling accuracy while reaching greater depths.

“We’re able to do more CPT pushing through sand layers and denser materials, gathering more data than before. With a traditional rig, we’d start bending rods in stiffer materials rather than going deeper.”
