3230DT Drill Rig

• POWER: Tier 4 engine provides more than 15% greater horsepower when compared to the previous version.
• AUTO THROTTLE: automatically senses the load and adjusts throttle accordingly, saving fuel.
• LOAD-SENSE HYDRAULICS: supplies the system pressure required to perform requested tasks, reducing heating of the hydraulic fluid — important when operating in elevated ambient temperatures and performing high-duty operations such as coring, augering, or tracking long distances.
   

The patented CB Combo Head is the heart of the 3230DT and perfect for augering and high-speed rotary work. For projects that require direct push sampling or driving large casing, the integrated GH70 Hammer has become standard.

Completing the CB Combo Head is our built-in patented hydraulic head clamp, allowing users to safely and quickly hold or pull rods, casings, or augers while maintaining an open tool string. It easily manages the 80,000 lb. of pullback from the drill mast. Additionally, the combo head has functionality for direct push / percussion, mud rotary, air rotary, and rock coring.
 

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 CB Combo Head, designed and built exclusively by Geoprobe^®, 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!
 

The DH105 Automatic Drop Hammer is equipped for Standard Penetration Testing (SPT) work. The easy-to-use drop hammer hydraulically swings out over the borehole after the combo head is sideshifted away from the tool string. The DH105 comes standard with a 140 lb. slug or can be equipped with slugs ranging from 100 to 340 lb., depending upon your needs.

FEATURES

• Easy on / Easy off design
• Conforms to ASTM Standards D1586
• Consistent results
• No cables or ropes needed for operation
• Hammer swings over hole without repositioning the whole machine
• Throw height can be adjusted within seconds
• Use your Geoprobe^® rig for both environmental & geotechnical projects
• SPT blow count results are used for obtaining strength & density properties of soil, designing foundations, & defining earthquake sensitive soils
   

The adjustable swing-arm control panel with intuitive layout allows the operator to perform multiple tasks effortlessly. Speeds, feeds, and pumps can be precisely dialed in with the electronic controls. The control panel’s ability to swing freely from the rig lets the operator be in the position needed to help align a rod or to be at a comfortable distance away from a spinning drill string. Even controls to side-shift the Combo Head and reposition the Automatic Drop Hammer are at the operator’s fingertips.

FEATURES

• Swing Arm for multi-positioning options
• Integrated Electronic Diagnostic System: An integrated Systems Display on the control panel 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.  It’s all there to assist the rig operator.
• Easy-to-Use, Organized Layout
• Digital Display Screen with Multi-function Output
• Integrated Head Feed Pressure Controls (optional): Adding the head feed pressure control option for rotary drilling takes the strain off the operator by eliminating the need to manually adjust head feed rate.  Head feed pressure control provides consistent bit weight control for better penetration rates and longer bit life.  It also permits effective hands-free operation with the addition of an interlocked rotation guard.
• Operator Presence Bar locks out controls when not engaged by operator
• Single Toggle Switch to go from Hammer to Rotation
• Variable Speed Control for Hammer and Rotation
• Variable Flow Control of Auxiliary Hydraulics
• Electric-Over-Hydraulic System for 
• Head Functions
• Manual Valves for Machine Positioning
• Emergency Stop
• Lockable Control Panel Cover for transport and storage
   

The 3230DT drill mast may be one of the more unique aspects of this new offering. With a retraction force of 80,000 lbf at the cylinder and 84 inches of travel, the 3230DT has the pullback needed for direct push work. 

If 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. The built-in Head Clamp can handle the 80,000 lb. of the rig’s pullback.

All of the machine’s functions are at your fingertips on the control panel, including the hydraulic controls for positioning the side-shift function of the CB Combo Head. The combo head travels up to 24 inches to the left and 2 inches to the right from center so you can work the inside diameter of the rod without moving the drill mast. When using the drop hammer, it hydraulically swings into place for operation over the hole.

The variable height telescoping winch mast, with a maximum height of 24 feet, allows your field team to trip 20-foot sections of tooling. The 3230DT can also be operated with the winch mast lowered to work under power lines, inside buildings, or when canopies or structures require a lower clearance. The telescoping mast can be outfitted with one, two, or three winches depending on user preference.

Features

• Line pulls up to 8,500 lbf and line speeds up to 191 fpm
• Telescoping winch mast hydraulically raises and lowers, variable operating heights
• Trip 20-foot. sections of tooling
• Maximum height of 24 feet
   

Optional front outriggers help keep the drill mast steady while drilling. With a 26-inch stroke, the drill mast can be left up while lowering the outriggers to have room for a mud pan, for using a breakout above the casing, or just to have extra room while augering.

The 3230DT comes with a wireless remote and a tethered remote. Features of the wireless remote include:

• Throttle Up / Throttle Down
• Raise and Lower the Blade
• Adjust Speeds (3)
• Paddles to Drive Tracks Independently
• E-Stop Switch
• Remote Uses Standard AA Batteries
   

Safety was a top consideration in the design and engineering of the 3230DT. Safety features include:

• Emergency stop on the control panel, wireless remote, tethered remote, and back of the machine instantly stop the rig
• Operator Presence Bar on the control panel locks out controls when not engaged by the operator
• Optional Rotation Guard
• Fire Extinguisher on the machine
   

With an adjustable clamp force of up to 17,500 lbf, the 3230DT breakout has an opening of 7 inches with hardened jaw pads to firmly grip casing. The breakout has a side pivot allowing it to swing over and away from the hole when not in use. 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.

Separate mud pump circuit eliminates the battle between drilling functions and fluid circulation for hydraulic flow and pressure, creating stable mud flow. 

A number of pumps are available for the 3230DT. These include:

• Progressive Cavity Pumps
• Hose Pumps
• Triplex Pump Kit

Pumps are typically used for mud rotary and rock coring applications.
