Equipment profile

Built around the project configuration

The GEOPROBE 3126GT is a crawler-mounted investigation rig that combines rotary drilling, direct push, SPT, CPT, Shelby-tube sampling, and hard-rock coring on one geotechnical platform. Its centerline side-shift system positions the selected head or testing function over the borehole without moving the carrier or resetting the mast.

The machine provides 2,667 mm of head travel, 160 kN of crowd force, and 214 kN of pull force. Four- and six-speed rotary choices, automatic drop-hammer equipment, integrated CPT controls, and direct-push tooling allow the working package to be selected around the required drilling and sampling program.
