The 8040DT
Muscle. Versatility. Speed. 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.
With the GH80 Hammer, this machine is capable of driving 2.25 in, 3.5 in. and 4.5 in tooling in areas that were previously unthinkable.
You just gotta see the 8040DT in action!
Multiple Applications
The Geoprobe® 8040DT arrives with exciting new possibilities, increased power, more versatility, and the push you need to stay ahead of the game!
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.
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.
