A Bold, High Performance Combo Rig Offering Impressive Results

The Geoprobe® Model 8040DT is a high-capacity direct push machine with a durable undercarriage, hollow stem auger capabilities, and a wide-base platform. As with all direct push machines, the hammer is critical to how well the machine performs in the field. The GH80 Hammer on the 8040DT is capable of driving 2.25 in. and 3.5 in. tooling to greater depths in tougher formations. Or if a larger volume soil sample or 2 in. well is needed, the GH80 direct drives the new 4.5 in. tooling completing projects that were previously unthinkable. Designed into the 8040DT is a long list of features. The machine incorporates a two-speed hydraulic top head for classic auger/drilling methods for lithologies not conducive to direct push techniques.
