Multipurpose Geological Engineering Drill Rig
1.The main mast of the drill rig provides rotary drilling support. Rotary drilling is performed via a hydraulic top‑drive power head to collect rock or soil samples. Depending on requirements, both conventional single‑tube drilling and wireline double‑tube drilling techniques can be implemented.
2.Based on the latest technology, the drill rig is capable of fully automatic Standard Penetration Testing (SPT), with sampling depth up to 50 meters and SPT penetration depth exceeding 20 meters. The hammering frequency can reach 50 blows per second, and an automatic counter enables real‑time test recording.
3.The telescopic winch mast system can handle drilling tools of 1.5 to 3 meters in length.
4.The mini crawler system allows remote‑controlled travel and drill rig lifting/leveling. It offers high maneuverability and flexibility, enabling free self‑movement on the worksite. Various tools can be stored on the rig.
5.The drill rig has a compact structure, facilitating transport by small trucks. It can self‑crawl for loading and unloading, making both short‑distance relocation and long‑distance transportation extremely convenient.
6.The AM75G soil sampling system can preserve the original state of soil samples while also allowing SPT and gravity probe tests.

Product details
1. Dual-clamp drill pipe handling system
Adopts an independent upper and lower dual hydraulic clamp structure with modular split design. Each level is equipped with dual hydraulic cylinder drive, enabling automatic clamping, unscrewing, and precise centering of drill pipes. This dual-clamp configuration alternately completes make-up and break-out of drill rods during drilling without manual intervention, significantly improving deep-hole drilling efficiency. Meanwhile, mechanical locking and hydraulic cushioning effectively protect drill pipe threads and extend tool life.
2. High-torque rotary power head assembly
The power head unit features an integral cast housing with a large-diameter spindle and multi-bolt flange connection, capable of withstanding high-torque drilling conditions. The integrated hydraulic motor and guide-rail feed mechanism enable synchronous control of rotation and axial feed. External high-pressure hoses are wrapped with spiral protective sleeves to resist abrasion and corrosion on the worksite, ensuring stable hydraulic oil supply and meeting efficient drilling requirements in hard rock and complex formations.
3. Dual-mode control unit
Equipped with a portable wired remote control handle that supports remote operation, allowing operators to adjust drilling parameters from a safe distance to meet safety requirements under complex working conditions. A built-in cable storage design balances operational flexibility with equipment cleanliness.
4. Integrated main control console
Multiple hydraulic joysticks with zone control for rotary, feed, clamping and other actions – the operation logic is clear, reducing the risk of misoperation.
A digital display and pressure gauge set provide real-time feedback of core parameters such as drilling pressure and rotation speed, enabling precise control of drilling conditions.
A red emergency stop button, status indicator lights, and function switches form a complete safety protection system, ensuring equipment and personnel safety.
5. Overall design highlights
Modular structure design: The clamps, power head, and control system can be independently maintained and upgraded, suitable for multiple scenarios such as geological exploration, trenchless construction, and mine rescue.
Industrial-grade protection design: Key hydraulic components and pipelines adopt wear-resistant and anti-corrosion protective structures to adapt to complex field conditions, improving equipment reliability and service life.
Ergonomic optimization: The console layout conforms to operating habits; the dual remote and local control modes balance efficiency and safety while reducing operator fatigue.
Scope of application
1.Geological Exploration Drilling
Suitable for regional geological surveys, mineral prospect evaluation, and detailed exploration阶段的 sampling drilling. With the parallel design of the rotary mast and percussion mast, the drilling mode can be flexibly switched in different formations such as hard rock and unconsolidated layers, meeting the exploration needs of core drilling, hydrogeological drilling, etc.
2.Geotechnical Engineering Drilling
Widely used in engineering geological investigations, such as geotechnical investigation holes, in-situ test holes, and observation holes for building foundations, bridges, tunnels, slopes, etc. The compact and powerful mast structure combined with sliding positioning enables precise hole placement in narrow or complex sites.
3.Rough Terrain and Rapid Relocation Operations
Equipped with engineering machinery crawler tracks, remote-controlled travel, and frame lifting functions, the drill rig can self-climb over obstacles and quickly complete repositioning and leveling. It is particularly suitable for areas difficult for large equipment to access, such as mountains, hills, and construction debris sites, as well as worksites requiring frequent movement between multiple scattered points.
4.Emergency and Rescue Engineering
High mobility and simple remote control allow the rig to quickly reach disaster sites such as landslides, collapses, or piping emergencies for emergency investigation or grouting drilling, providing timely geological data for rescue decision-making.
In summary, the GM75 is a multifunctional rig that combines efficient drilling capability with high mobility, especially suitable for geological exploration and engineering drilling projects characterized by scattered work points, complex terrain, and variable formations.
