Drill More. Make More.

Drillers seeking to position for increased productivity and profit choose the 3126GT geotechnical drill with its innovative centerline head side shift and separate hydraulic circuit for mud pump. Engineered for efficiency in a small footprint on wide tracks, the compact geotechnical drill nimbly navigates off-road without sacrificing power or versatility. The end result – faster, easier, and safer drilling.

  • trim time between applications with six functions along the centerline head side shift
  • reduce strain of rotary work with hands-free rotation and feed
  • maximize production and rig utilization with power and versatility

Advance augers with the 4 or 6-speed rotary head. Then use the geotechnical drill hydraulics to slide the head over to position the hands-free automatic drop hammer for driving SPT samples between core runs. Or use the geotechnical drill 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 integrated GH63 direct push hammer for fast and easy direct push soil and water sampling in unconsolidated formations — with your feet safely on the ground. No moving drill mast or machine.

Taller telescoping winch mast on 3126GT specifically designed for geotech work

The winch mast telescopes into place, allowing for flexible height options based on work environment. This also adds a layer of safety during setup when working near overhead power lines or other obstacles. 

Taller telescoping winch mast specifically designed for geotech work with heavier winch options, 105-inches head travel, and 36,000-lbf push and 48,000-lbf pull at the head-feed cylinder means greater pull back – ideal for drive and wash – and head travel. Allows tripping out of 20-foot lengths of rod when combined with 3-foot extension. 

Align the probe cylinder and tool string on a straight – or angled – path to the subsurface while the machine remains stable with the built-in oscillation, standard on all machines. 

Drill mast features extend, swing, mast dump, oscillation, and fold. Mast dump provides 36.5 inches of vertical travel to allow room for a mud pan. Optional outriggers available.
 


Winch Options


Dual winches typically configured with 6,000-lbf and 1,800-lbf

Dual winches typically configured with 6,000-lbf and 1,800-lbf

A dual winch option is typically configured with a 6,800-lbf winch for the more difficult pulling and an 1,800-lbf. with quick-change hook. When ready to switch from pulling to coring, simply swap out the swivel hook for the overshot clevis installed on your overshot and continue working. It’s quick, simple, and can all be done by hand.

Additional winch options include 2,500-lbf and 1,100-lbf. 

Also available is a third winch with 1,100 lbs of line pull, well suited to trip additional tooling out of the hole. Equipped with the Geoprobe® exclusive quick change hook, operators can switch over to wireline coring in seconds. 


Higher Torque Rotary Head


GR6.5 Rotary Head provides 70 percent more torque

GR6.5 Rotary Head provides 70 percent more torque

While customers are proving the rock coring capabilities of the 4-speed rotary head on the 3126GT, some customers have requested more bottom-end torque for their geotech jobs. True to form, Geoprobe® responded by designing the 6-speed GR6.5 rotary head with 70 percent more torque.

"The GR6.5 has 6,800 ft-lbs of torque, which is 2,800 ft-lbs more than the GR4.1 on a typical 7822DT, without sacrificing top-end speed (720 rpm)," Ryan Kejr, machine engineer lead, said. "We also added an additional intermediate-speed range, which further enhances the unit's wet and air rotary capabilities."


Control Panel


Controls include hands-free rotary and head feed

Controls include hands-free rotary and head feed

All functions are at your fingertips in a well-organized, compact control panel. The systems display provides real-time systems analysis and a suite of built-in diagnostic tools. Also included are system safeguards that protect the main engine and hydraulic components when important operational parameters are compromised.

Hands-free rotary and head feed controls on the 3126GT reduce strain on driller when completing applications like mud rotary. CPT feed rate and hydraulic limit functions are standard.
 


7-inch Single Clamp Breakout


Breakout on 3126GT geotechnical drill has a clamp force of up to 21,000 pounds of force

Breakout on 3126GT geotechnical drill has a clamp force of up to 21,000 pounds of force

The 7-inch single breakout firmly grips casing with a clamp force of up to 21,000 pounds of force. The breakout can be positioned either under the hammer or the rotary drive, as well as swung away from the machine.

An optional Coring Upgrade Kit (217024) is also available to firmly grip thin-walled 2.75-inch OD casing without damage to the casing. The kit includes formed jaw pads and a circle wrench with carbide inserts.
 


Tooling Transportation/Storage


Toolboxes help with site housekeeping while rear blade on 3126GT geotechnical drill easily transports tooling drop rack

Toolboxes help with site housekeeping while rear blade on 3126GT geotechnical drill easily transports tooling drop rack

The rear blade can be used for tool transport. During site setup, a tooling drop rack can be placed in front of the machine for easy access. This eliminates the need to walk around the machine for tooling, which saves time and conserves energy in the field. 

Ample, well-spaced storage includes two stacked tool boxes, helper-side storage compartments, and control panel storage bin/trays.


Folding Winch Mast Option


Folding winch mast lowers transportation height by 15 inches

Folding winch mast lowers transportation height by 15 inches

The folding winch mast option for the 3126GT is designed for customers who prefer to haul their rig in an enclosed trailer or truck, lowering the transportation height by 15 inches.

"This reduces the transport height of the 3126GT from 114 inches to 99 inches," Ryan Kejr, machine engineer lead, said. "We accomplish this with a simple, mechanical ratcheting actuator. This is easily accessible from the ground when the drill mast is in transport position."

The rig has a lot of push/pull capacity but also a lot of control. The hydraulic lever handles we're used to versus the display and ability to tune controls on the 3126GT control panel is way, way ahead of other drilling rigs. How Geoprobe® worked out the operating system impressed me more than anything. They took care of all the little details to make things easier in the field.

Tooling & Accessories

Augering with the 7822DT

Hollow Stem Augers (HSA) are commonly used to set groundwater monitoring wells for environmental and for geotechnical SPT applications. With the option of an augerhead on Geoprobe® machines you can turn hollow stem augers with the same machine you had just been using for percussion probing.

Interlocking Split Spoon Sampler

Video: Interlocking Split Spoon Overview

Engineered to be stronger, last longer, and save money and time, the patented interlocking split spoon meets ASTM Standard D1586.The finger-like design self aligns, creating a perfect fit and quicker assembly. With the threads aligned, the cutting shoe and drive head can be threaded to the split spoon. Multi-lead threads require fewer turns during assembly and disassembly over conventional split spoons, speeding up each test interval.In additional to time savings, enhanced material properties and manufacturing result in greater longevity. Each interlocking point keeps the two tube halves engaged throughout the sampling process. The strength of these connections prevents the sampler from bulging in dense materials. It also keeps the tube halves tightly engaged even when over-filling of the sampler occurs.

Spring Assisted Swivel Lift Cap

Video: Geoprobe® Spring Assisted Swivel Lift Cap

The Spring Assisted Swivel Lift Cap is designed to reduce operator fatigue when adding or removing sections of rods to the inner tool string. The internal springs of the pull cap bear the weight of the rod string. With minimal effort, the operator can adjust the rod string up or down when threading or unthreading the rods. The natural self-alignment of the rod string prevents tipping off center and binding of the threads.

MC5 Core Sampler Soil Sampling System (LWCR)

Video: Geoprobe® Macro-Core® Center Rod

Our MC5 Soil Sampling System is a single tube, discrete or continuous system with unmatched durability.MC5 Light Weight Center Rod Soil Sampling System. The MC5 1.25-inch Center Rod System was designed for the absolute worst of the worst direct push probing conditions. “These are conditions that we normally do not recommend probing in,” according to Mike Carlin, Project Engineer, “so we developed the toughest soil sampling system in the direct push industry ... it’s a brute!”Macro-Core® is a registered trademark of Kejr, Inc., Salina, KS.

DT22 Soil Sampling System

Video: DT22 Soil Sampling System Overview

The Geoprobe® DT22 Soil Sampling System is a direct push system for collecting continuous core samples of unconsolidated materials from within a sealed casing of Geoprobe® 2.25- inch outside diameter probe rods. Samples are collected and retrieved within a liner that is threaded onto the leading end of a string of Geoprobe® 1.25-inch OD light-weight center rods and are inserted to the bottom of the outer casing.

3.75 in. Tooling

The DT37 Soil Sampling System, designed for use with 3.75-inch probe rods, uses a unique combination of the cutting shoe, sheath, and liner retainer to allow efficient recovery of samples in formations ranging from plastic clays to saturated sands. The DT37 system is designed to quickly recover samples well below the water table. Problems with liner failure or having the liner lodge in sample sheath are virtually eliminated with this system.

SP22 Groundwater Sampler

Video: SP22-ISP Groundwater Sampler

The Screen Point 22 (SP22) Groundwater Sampler from Geoprobe Systems® was designed to keep the screen away from all percussive energy while the sampler is lowered downhole, thus extending the life of the screen.The SP22 can be used alone as a groundwater grab sampler or groundwater profiling tool, or with the DT22 Soil Sampling System. The screens can be deployed using either 1.25-inch Lightweight Center Rods or PVC riser.Designed for tough probing conditions, the screen head on the fully retrievable sampler adapts to either a stainless steel or PVC screen.
