Model 7730DT

The Geoprobe® Model 7730DT is a high-capacity direct push machine with a durable undercarriage, hollow stem auger capabilities, and a wide-base platform. This machine is equipped with many of the features Geoprobe® customers are accustomed to, and with many new advantages to offer customers flexibility in all types of field conditions.

Wider Platform. Longer Stroke. More Durable Undercarriage.

These are all design elements in the newest Geoprobe® Direct Push Machine ... the Model 7730DT. Together with a long list of popular features, this higher capacity machine offers still more advantages to our customers which allows them more flexibility in all types of field conditions.

The heart of the machine is the powerful GH62 hammer which Geoprobe Systems® designed specifically for direct push applications. A dependable 75 hp Kubtoa 4-cylinder turbo diesel engine powers all of the hydraulics used on the machine.

Darin Huelsman, Project EngineerDarin Huelsman, Project Engineer, says this machine is one more reason why Geoprobe® customers do well in the environmental business. The 7730DT was designed from the beginning to accomplish specific tasks as a direct push machine. “We knew how we wanted the 7730DT to perform before its tracks ever hit the ground,” Darin said. “Our machines, especially this one, are an accumulation of listening to what customers want and adding what we know to make the whole package come together and be profitable for them.”

And this is a big package! The undercarriage is 18 in. wider than the Model 6620DT which adds stability in the field for deep subsurface work and augering. It’s a great foundation to support all the work you can do with the two-speed augerhead, an overhead mast and hydraulic winch, and two-speed probe cylinder ... all of which are standard features of the 7730DT.

“After you see this machine perform in the field,” Darin added, “you’ll wonder how you worked without it! Come to Kansas and spend time at the controls. This is truly a machine you need to run to appreciate.”

Easy to load.  On the go again...

Markus Hirsch (above), with the Centre for Environmental Research (UFZ) Leipzig-Halle, Germany, is at the controls of a new 7730DT at a Zeitz fieldsite near Leipzig. With him is Mike Schlorke, employed by Dr. Koerner Geomonitoring in Leipzig. Their task was the detection of a benzene plume using the 7730DT and the Electrical Conductivity Logging System. They used 1.5 in. rods for the EC logging along a profile line perpendicular to the general groundwater flow direction. (Below) In addition to the EC logging, the field team took multi-level groundwater samples and did an onsite analysis of the samples in a mobile lab brought to the site.

Model 7730DT Features:

  • Power to reach deeper probing depths
  • 77 in. (1956 mm) probe cylinder stroke allows use of 60 in. (1,524 mm) probe rods
  • Two-speed probe cylinder cycles from bottom to top in less than 5 seconds
  • Equipped with the powerful GH62 Hammer
  • Heavy Duty Undercarriage has a wider track that carries more weight, adds more torque, reduces ground pressure and handles greater tool weight
  • Ground speed up to 4.5 mph
  • 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, 75 Hp, liquid-cooled Kubota turbo diesel engine
