Machine Applications

Excel in the Geotech MarketThe Geoprobe® 3230DT is a mid-sized tracked drill rig combining advanced direct push functionality with traditional geotechnical

auger rig and high-speed rotary drilling capabilities. All of the features of the 3230DT come together to create a rig that is efficient at

what it does. Using customer feedback and past experience, we combined all of the features that make drilling easy into this machine,

creating a platform that performs well in direct push and rotary applications. The high torque and high speed rotary range of the

4-speed head opens the doors to all kinds of field tasks. The patented CB6 combo head is capable of putting a lot of power into hollow

stem augers while also having the control and finesse to run high-speed wireline tools. When you add in a powerful GH70 hammer

and the ability to switch between tasks quickly, you have versatility with ease. You may not use all of the functions on every project,

but if you need to auger to bedrock and then do a confirmation core, it’s all there. Just set up and go to work!

The 3230DT has what you need for diamond coring: drill mast outriggers stabilize the unit above the pan, multiple water pump and breakout options are available, head feed pressure controls (weight on bit) are integrated into the control panel, and the spindle features rotation

of up to 800 rpm.

3230DT diamond coring results: N-sized limestone and shale coresfrom 225 ft.

Oscillation +/- 11 degrees from center allows the field team to easily align the rig over the hole in tight and uneven conditions.

The telescoping mast, with a maximum height of 23 ft. 10 in., allows the field team to trip 20-ft. sections of tooling. The 3230DT can also be operated with the winch mast

lowered (shown here) to work under power lines or inside buildings or when canopies or structures require a lower clearance.

Machine Applications

Augered Monitoring Well InstallationLarger diameter monitoring wells are often installed through hollow stem augers. Customers report that the optional GA4100/GA4000 augerheads on 78 machines exceed their expectations for augering work.

Standard Penetration Testing (SPT)78 Series machines can be equipped with an automatic drop hammer (optional) for performing SPT testing for geotechnical investigations. The 78 rigs can advance borings for SPT testing by augering, driven casing and sampling, or wash boring. The compact size of the 7822DT enables it to access remote areas.

“EnviroTek was in the market to expand

our capabilities to support our work at

the mines. The 3230DT was the perfect

fit for our need to access remote areas

and increase our capabilities to drill and

sample deeper. The combination head

with 6,000 ft-lb. of torque and GH70

hammer were just what

we were looking for.”

POWERFUL. FAST.MULTI-FUNCTION DRILL MAST.

The 3230DT may be the most versatile machine

designed and manufactured by Geoprobe Systems®.

POWERFUL. The 99 hp Kubota diesel engine, mounted

on the 30-series track base, provides the power needed

to successfully complete geotechnical rotary work while

reducing upfront and operating costs.

FAST. Innovative features allow the 3230DT to transition

from driving casing via direct push to wet rotary drilling

in less than five minutes. Quickly and efficiently!

MULTI-FUNCTIONAL DRILL MAST. With a retraction

force of 80,000 lb. at the cylinder and 84 in. of travel,

the 3230DT has the pullback needed for direct push

work. The rig can be equipped with multiple winches

and a telescoping winch mast allowing the tripping

out of 20-foot sections of tooling. Drill mast outriggers

add to the rig’s stability during rotary applications. For

DTH hammer and diamond coring work, the head feed

pressure control allows the operator to simply control

the weight on bit from the control panel. In addition,

multiple tool breakout options are available for up to 25

tons of pullback. The 3230DT will be an asset to help you

complete the work at hand and to expand your markets.

The patented Geoprobe® CB6 Combo Head is the heart of the 3230DT and the key to the rig’s versatility. Each feature of the four-function

combo head opens up additional applications and services you can offer your customers. The head can be configured with a 4- or 2-speed head,

and with or without a percussion hammer. The head moves side-to-side (side shifting) and has patented rod grip features.

Geoprobe® CB6 Combo Head

One of the key features of the 3230DT is the patented

CB6 Combo Head, designed and built exclusively by

Geoprobe Systems®, which makes it one of the most

versatile machines on the market. The high torque

and high-speed rotary range of the 4-speed

combo head opens the doors to all kinds

of field tasks. This head is capable of

channeling a lot of power into direct push

casing advancement and the speed and

torque for turning hollow stem augers

(up to 10.25 in. ID) while also having the

control and finesse to run high-speed

wireline rock coring tools. When you

add in a powerful GH70 Hammer

and the ability to switch between

tasks quickly, you have versatility

with ease. There’s no need for another

drill rig or support equipment ... the 3230DT was

designed to keep utilization rates high using just

one rig.

After running this rig for a short time, you’ll be impressed with how easy and conveniently the

3230DT transitions from driving casing via direct push to wet rotary drilling ... in less than five

minutes. The patented CB6 Combo Head, designed and built exclusively by Geoprobe Systems®, allows

you to do direct push hammering for sampling and monitoring well installation. The rotation function of

the head allows for different drilling techniques, such as air rotary, wet rotary, overburden rotary systems,

augering and rock coring. The rotation function handles the full 80,000 lbf of pullback required for a machine

of this magnitude. And with the integrated hydraulic head clamp, you can easily hold or pull rods, casings, or

augers while maintaining an open top tool string. Geotechnical Standard Penetration Testing (SPT) with the

Automatic Drop Hammer provides for easy sampling through the inside diameter of both hollow stem augers

or driven casing. Each function of the combo head opens up additional applications and services you can offer

your customers. And you can do it all with ONE MACHINE!

CB6 Combo Head

Automatic Drop Hammer FunctionRounding out the multiple functions of the CB6 Combo Head is the new DH105, and Automatic Drop Hammer for Standard Penetration Testing (SPT) work. The drop hammer is hydraulically swung out over the hole after the Combo Head is sideshifted away from the hole. The DH105 Automatic Drop Hammer comes standard with a 140 lb slug, or can be equipped with slugs ranging from 100 to 340 lb depending upon your needs.

Automatic Drop Hammer

Direct Push Hammer

Head Clamp

Head Clamp FunctionIf you’re using the Direct Push Hammer, you need to be able to pull casing back out of the ground. For that reason, engineers incorporated our patented hydraulic head clamp within the combo head to safely and quickly pull rods ranging from 1.25 to 6.0 in. OD while maintaining an open ID to speed up well installation.

Direct Push Hammer FunctionFor over 25 years, the backbone of the Geoprobe® brand has been the design and manufacturing of direct push equipment. We’ve incorporated our popular GH60 class hammer into the design of the CB6 Combo Head for direct push work. Or, if you need more power, the new GH70 hammer has the percussive energy needed to drive larger casing. You can equip your 3230DT with either hammer, or go with no hammer at all.

Rotary FunctionMultiple options of the combo head are available for rotary work. The 2-speed variant of the CB6 Combo Head has up to 6,000 ft-lbf of torque in Range 1, and a top speed of 150 rpm in Range 2 and is well suited for turning augers. For high-speed work, like diamond coring, a 4-speed variant of the CB6 is available with 6,000 ft-lbf of torque in Range 1 and a top speed of 800 rpm in Range 4. The 4-speed CB6’s combination of a manual shift selector and a hydraulically-shifting motor allows the operator to pick the speed and torque required for the job.

There is ample room under the combo head to run 10.25 in. ID

hollow stem augers. (Shown here with 6.25 in. ID HSA.)
