Proven Features of Geotech Drilling Rigs Plus More Power

For some, rock coring or geotechnical assessments in tough geologies means sacrificing the convenience and ease of your Geoprobe^® rigs for the perceived power of giant mechanical geotech drilling rigs. You wish you didn't have to suffer the headache of mobilizing an oversized one-trick-pony, wearing down your veteran drillers with extensive manual labor, and intimidating next generation drillers with complicated operation. Now you don't have to.

With the NEW 3135GT, the speed, ease, and safety you've come to appreciate from your Geoprobe^® combination rigs now comes with additional power needed for tougher jobs.
• 10,000 ft-lb true torque
• 1,000 rpm

Efficiently tackle your toughest jobs with a smaller footprint and the added convenience of carrying your tooling on a drop rack.

Employ multifunctional capabilities inherent on today's Geoprobe^® geotech drilling rigs without manipulating drill mast position or mobilizing multiple machines.

With 3135GT geotech drilling rigs, you can minimize operating costs while maximizing utilization. The end result — launching drilling production and profit ahead.
