Drill More. Make More.

No one wants to be stuck trying to squeeze profits out of a clunky conventional drill rig. A stealthy, compact rig that swiftly slides from rotary to automatic drop hammer even to CPT or direct push without having to move mast or machine positions you for increased production and profit. Discover how this innovative centerline head side shift on the compact, off-road 3126GT can propel your company forward. The price point comes in lower than you might anticipate, especially when considering all the features that minimize your operating costs.

Features & Options

SPT Sampling with the Automatic Drop Hammer.

SPT Sampling with the Automatic Drop Hammer.

Advance augers with the 2 or 4-speed rotary head with increased stability afforded by the outriggers. Then use the machine hydraulics to slide the head over to position the hands-free automatic drop hammer for driving SPT samples between core runs. Or use the controls to slide the head the other way to conduct CPT logging using the integrated CPT head-feed rate controls complete with cone overload protection. Or use the GH6300 direct push hammer to see the subsurface with Direct Image® tooling.

No manipulating the mast position. No mobilizing multiple machines.

A taller telescoping drill mast specifically designed for geotech work with heavier winch options, 105” head travel, and 36k push and 48k pull at the head-feed cylinder means greater pull back – ideal for drive and wash – and head travel.

The 3126GT has room to work above a mud pan.

The 3126GT has room to work above a mud pan.

The small footprint increases accessibility but still includes room for a separate hydraulic pump for the mud pump (stabilizing mud flow) and space for accessories. And with more mast dump, you’ll have room to work above the mud pan.

The controls of the 3126GT bring new drillers up the learning curve quickly.

The controls of the 3126GT bring new drillers up the learning curve quickly.

Side-shifting the head of the NEW 3126GT along the centerline simplifies the process of augering, mud rotary, SPT, Shelby tubes, hard rock cores, CPT and even direct push - safely boosting rig output and utilization, moving the needle on production and profit. Bring new drillers up the learning curve quicker with the easy controls and integrated safety features built to internationally accepted standards.
