150GT Geotechnical Drill Rig
Video: Geoprobe® 150GT Features
Driving Force for Your Geotech Jobs
Drillers demanding speed achieved by operating 10-foot tooling choose the 150GT geotechnical drilling rig. The geotechnical drilling rig under class A/B CDL effectively completes traditional geotechnical drilling applications utilizing hollow stem auger, solid stem auger, SPT, mud rotary, air rotary, and high-speed coring without needing to reposition mast or machine to become the driving force for your geotech jobs. Additional advantages of the quiet geotechnical drilling rig include:
- Swinging the automatic drop hammer over the tool string, or sliding the rotary head into position and engaging the hands-free rotation with a touch of the controls keeps your driller out of the danger zone
- Creating stable mud flow with a separate hydraulic circuit dedicated to the mud pump eliminates the battle between drilling functions and fluid circulation for hydraulic flow and pressure
- Providing maneuverability and modern amenities in a fuel-sipping, comfortable geotechnical drilling rig makes it kinder to your bottom – line – and safer for your new drillers
Veteran drillers especially appreciate the comfort of the geotechnical drilling rig but also the operating versatility. Training new drillers is efficient thanks to the easy operation and safety features (beyond just e-stops) of the 150GT geotechnical drilling rig, including:
- Ditch-side control panel putting more distance between traffic and operator
- Telescoping mast reducing power line collisions
- Hands-free controls for feed and rotation facilitating rock coring and mud rotary
Features & Options
150GT geotechnical drilling rig engineered to use 10-foot tooling systems
Owners consistently using 10-foot tooling systems depend on the 150GT geotechnical drilling rig to perform jobs efficiently, paramount for successful geotechnical sampling. Profits lie not only in getting footage done quickly and easily, but above all, safely. Quality construction and numerous features and options on the geotechnical drilling rig provide power to outperform the competition.
- EASY: perform geotechnical drilling applications without manipulating mast position or mobilizing multiple machines - simply set it and forget it. Controls grouped by function make it easy to move several levers simultaneously. Hands-free controls for feed and rotation reduce operator fatigue during rock coring.
- EFFECTIVE: versatility to complete an array of sampling techniques – in unconsolidated and consolidated formations - with a single machine without compromise. Separate hydraulic circuit dedicated to mud pump provides stable mud flow.
- EFFICIENT: fuel-efficient transport averages at 15 mpg and minimizes maintenance expenses supporting only one engine while providing power to travel at highway speeds. Ample storage keeps tools right where you need them near the control panel or on the breakout. And because the geotechnical drilling rig is under class A/B CDL, save on insurance and streamline hiring of new drillers.
With drill rig service shops in Florida and Kansas, you’ll have service support nearby for your routine maintenance or more in-depth drill rig remounting and refurbishment work. Our service technicians are backed by our team of engineers to ensure solutions not bandaids to issues. And our production processes mean your geotechnical drilling rig is constructed consistently and tested thoroughly to ensure easier service support.

CB5 4-Speed Head
CB5 4-speed head on 150GT features 22-inch head side shift
The CB5 4-speed head on the 150GT geotechnical drilling rig features:
- 6000 ft-lb torque; 600 rpm (torque to spin augers, speed to high speed core)
- Full torque in forward and reverse; On-the-fly shift between 1 and 2, 3 and 4
- Floating top swivel with 1-5/8-inch thru bore and 2.5 inches of float and 2-3/8 inches API Internal Flush thread
- 6.25-inch external drive for HSA
- Rod grip puller (1.5-inch to 5-inch rod)
- Head side-shift (22 inches)
Telescoping Winch Mast/Drill Mast Oscillation
Trip out 20-foot lengths of rods when adding the 3-foot extension to the telescoping winch mast on the 150GT
The telescoping winch mast reduces the overall height of the rig, but still allows the tripping out of 20-foot lengths of rod when combined with the 3-foot extension.
The drill mast on the 150GT geotechnical drilling rig features:
- 144 inches of head feed travel & 45 inches of drill mast dump (this easily gives you the range you need to work ground level, above a pan, or drill at an angle)
- Head travel speeds up to 140 fpm
- Rollers instead of slides
- Easily adjust to hole misalignment with extend and swing
Automatic Drop Hammer
Integrated safety features protect operator from improper deployment of automatic drop hammer on 150GT geotechnical drilling rig.
The DH107 automatic drop hammer on the 150GT is designed to make your job efficient.
- Allows operator to swing in drop hammer while head is still attached to the tool string
- Integral safety features to protect the operator from improper deployment
- 73 inches of float to easily accommodate different sample intervals
Control Panel
Hands-free operation increases safety on the 150GT geotechnical drilling rig.
The manual controls on the 150GT provide the tactile feel that some drillers prefer, while the electric control adds safe hands-free operation.
Breakout
Breakout on 150GT allows for flexible positioning
The 7-inch single breakout firmly grips casing with adjustable clamp force up to 21,000 lbs. The breakout can be positioned either under the hammer or the rotary drive, as well as swung away from the machine.
No Class A/B CDL Required
150GT geotechnical drilling does not require a class A/B CDL
The easy to drive, automatic transmission truck does not require a CDL (Class A/B). This lowers upfront costs and allows for lower maintenance costs.

Tooling & Accessories
Video: Geoprobe® Spring Assisted Swivel Lift Cap
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.
