Geotechnical drilling projects often face significant challenges. Harsh terrains and complex ground conditions can slow down work and increase costs. Traditional drilling rigs are often bulky and complicated to operate, directly impacting project timelines and budgets. This was a challenge for John, a senior geotechnical engineer in the USA. He was looking for a high-performance, user-friendly SPT rig to improve efficiency and reduce costs on his projects.
Why Choose YG’s SPT Rig?
John’s project had strict requirements. They needed to sample both soft soils and hard rock. This called for a powerful and versatile rig. John had tried several suppliers, but either the equipment was unreliable or the after-sales support was lacking. That’s when he discovered YG Machinery. He was immediately impressed by YG’s SPT rig, which was not only powerful but also designed with the user in mind.
The YG SPT rig features a crawler chassis, allowing it to navigate rough terrain with ease. It’s also equipped with a remote-control system for safe operation from a distance. The telescopic mast structure eliminates the need for an external drill tower, which saves significant setup time. Its top-drive power head and long-stroke guide rail greatly improve drilling efficiency. This design also ensures excellent directional accuracy without the need for frequent rod changes.

How the SPT Rig Handled Complex Ground Conditions
John’s project required sampling various geological layers, from soft soil to hard rock formations. This demanded a rig with exceptional adaptability. YG’s SPT rig was the perfect solution. It can perform Standard Penetration Tests (SPT) with ease and also use wireline coring technology to retrieve high-quality core samples from rock formations.
The rig’s full hydraulic transmission system makes operation flexible and precise. The stepless speed control ensures stable drilling with minimal vibration. The thin-walled diamond wireline coring technology enables faster drilling speeds and retrieves a larger core diameter. This is crucial for accurate geological analysis. YG’s spt drilling machine is trusted globally, with sales to countries like Russia, Kazakhstan, and Australia, showcasing its competitive edge.

User Feedback and Quantifiable Results
John and his team began using the YG SPT rig, and the results were immediate. The rig was easy to operate, and his team quickly got the hang of it. The remote control feature significantly enhanced on-site safety. The project timeline was shortened by 30%, and the core recovery rate reached an impressive 98%. This allowed them to get more accurate data than ever before.
John was very satisfied. “We used to spend so much time on equipment maintenance,” he said. “Now, our productivity has increased significantly. YG’s service team was also professional. They provided detailed pre-sales consultation and a customized solution for our project. Their prompt remote technical support was a huge relief and gave us peace of mind.”

SPT Rig Return on Investment (ROI)
Investing in YG’s SPT rig was a smart business decision. While there was an initial cost, the return on investment was substantial. The increase in productivity led to shorter project cycles and lower labor and operational costs. Accurate sampling reduced the need for rework, saving significant money. The full hydraulic core drilling rig from YG helped John’s company win more bids and increased their market competitiveness. Plus, with a small footprint and no need for foundation work, it’s an eco-friendly choice.
