7822DT Drill Rig

TIER 4 POWER: Experience the power you need – when you need it – and operating and fuel efficiency you require with the hydraulic, load-sensing system and auto throttle.

COOLING: Complete high-duty cycle operations such as coring, augering, or tracking long distances when operating in elevated ambient temperatures.

STABILITY: Use the rear blade to transport a drop rack tool carrier when desired while the wider tracks and shifted center of gravity better facilitate stability on uneven surfaces.
 

Exclusively from Geoprobe^®, an entire R&D engineering team designed, tested, and built the GH63 Percussion Hammer. Modular Percussion Power Cell Technology saves owners money and time when it comes to service. The power cell section can be quickly removed then economically shipped via standard overnight carriers for easy service and quick turnaround. More Power. Easier Serviceability. 

Torque-in hollow stem augers or complete high-speed rock coring when you choose the rotary head – integrated onto a swing-out mounting system – that best meets your needs. Both head options have up to 4,000 ft-lbs of force.

The two-speed head has a top speed of 150 rpm, and the four speed head has a top speed of 750 rpm. When running SPT through 3.25-inch hollow stem augers, the auto drop hammer can be swung into place over the borehole.

Rock coring can be completed using the four-speed GA4100 high speed water swivel system. Diamond core drilling is done on the 7822DT using industry standard wireline diamond coring drilling tools. 
 

Perform SPT testing for geotechnical investigations with the optional drop hammer. The 7822DT can advance borings for SPT testing by augering, driven casing and sampling, or wash boring.

A dual winch option is typically configured with a 2,500-lb winch for the more difficult pulling and an 1,100-lb. winch for the faster, deeper wireline work. 

A single winch system is available as well. Options for this include 2,500-lb, 1,800-lb, and 1,100-lb. winches.

The 2,500-lb winch has a line speed of 125 feet per minute and a line capacity of 75 feet. The 1,800-lb winch has a line speed of 125 feet per minute and a line capacity of 175 feet. The 1,100-lb winch has a line speed of 230 feet per minute and a line capacity of 250 feet.

Both the 1,800-lb and 1,100-lb winches are configured with a quick-change hook and overshot clevis - a feature exclusive to Geoprobe^®. 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.
 

To fit your needs, the frame rail design makes the 7822DT expandable with a number of factory options that include pumps, extruders, racks, and tool boxes mounted on the frame rail system. In addition, hangers are available to build your own custom accessories.

Wireless and tethered remote control systems come standard. Both remotes allow the operator to maintain a safe distance from the machine while tracking and include E-stops to quickly shut down the machine in an emergency.

The freedom of movement of the wireless remote enables a nearly unlimited view of machine surroundings. It’s also convenient when maneuvering in limited access locations or over rough terrain. Engine controls on the transmitter provide the convenience of starting or stopping the engine as well as adjusting rpm with the wireless remote.

The tethered remote allows for corded tracking of the machine. It is often used on sites that do not allow a wireless remote system and is a backup to the wireless remote.
 

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. When necessary, a 3-foot mast extension can be added to the rig.

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. 
 

The rear blade can be used for machine stabilization as well as 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. The lift capacity of the rear blade is 2,000 lbs.

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.

A number of features are built into the 7822DT to reduce engine load and fuel consumption. Load sense hydraulics supply only the system pressure required to perform requested tasks. Under light or no load conditions, system pressure is lowered, significantly reducing heating of the hydraulic fluid and burning less fuel. This feature is especially helpful when tracking the machine long distances, operating in elevated ambient temperatures, and performing high duty cycle operations such as coring or augering.

Additionally, an auto throttle function can be enabled on the control panel of the 7822DT. When enabled, the engine speed is controlled automatically. This allows the machine to go into full throttle when working and back to idle when not working. In addition to fuel savings, this creates a quieter work site.
 

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.

The breakout can be retrofitted on to all 7822DT rigs already in the field. 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.
