The hydraulic core drilling machine uses an advanced load-sensing hydraulic system. This allows smooth and precise control of both feed pressure and rotation speed, helping it collect high-quality core samples with a high recovery rate, even in complex ground conditions. Its modular design makes transport and setup much faster. One operator can handle most of the work, which greatly reduces labor and fuel costs. This is not just a drilling machine—it is also a platform that helps you collect valuable exploration data and take on higher-level projects for more profit.YG offers models HZ-130, HZ-180, and HZ-200.

Case Study 1
Client Background
A mid-sized mineral exploration service company based in Cambodia, which has been providing drilling services for international mining companies in the country’s gold exploration projects. The company previously owned two older vertical-axis core drilling rigs. While the team was experienced, the equipment was showing signs of wear.
Challenges
- The core recovery rate from the old rigs was unstable, especially in the complex weathered zones and faulted areas, occasionally failing to meet the data quality standards required by their partners, risking penalties.
- Equipment relocation was time-consuming and labor-intensive. In hilly regions, especially during the rainy season, it took several days to move one rig, severely affecting project schedules.
- International partners required more detailed drilling process records, but the old rigs couldn’t provide such data.
Solution
The company introduced a medium-sized hydraulic core drilling machine. Its modular design allowed easy disassembly and transportation by small trucks, greatly reducing relocation time. In the fractured zones, operators used the rig’s precise hydraulic control system, employing lower feed pressure and optimized flushing parameters to effectively reduce core erosion and clogging. The rig’s built-in data recording feature also met the partner’s demands for key drilling parameters.
Results
- Reduce disputes: The core recovery rate was significantly stabilized, meeting the contract’s quality standards and avoiding disputes over substandard core samples.
- Increase efficiency: The overall project efficiency improved, enabling the company to reliably meet deadlines.
- Increase efficiency: Additionally, due to enhanced operational efficiency and improved core quality, the company successfully joined the preferred contractor list of its international partner, gaining priority in future project negotiations.
Client Feedback
“For us, the key to this full hydraulic core drilling rig isn’t its flashy specs, but its stability and reliability. It gave us more confidence during negotiations, knowing we could deliver quality work on time. Although there was a learning curve, it was definitely worth it.”

Case Study 2
Client Background
A drilling contractor operating in Africa, providing exploration services for large lithium and cobalt mining projects. The company has a large fleet of equipment, but faces significant pressure from overall operational costs.
Challenges
- Traditional rigs consumed large amounts of fuel, with fuel costs making up a high percentage of total project costs, significantly eroding project profits.
- There was a shortage of skilled operators, and traditional rigs required intense labor, leading to high turnover rates due to the extreme heat.
- Equipment frequently malfunctioned in the high temperatures and dusty environments of the desert, with long waits for repair parts and technicians, which delayed project timelines.
Solution
The company purchased several hydraulic core drilling machines in batches. The new rigs featured a load-sensing hydraulic system that reduced fuel consumption. Automation functions simplified some of the more physically demanding tasks, decreasing the reliance on operator strength and shortening training periods. The manufacturer also provided enhanced air filtration and cooling solutions for high-temperature and dusty environments and, through its service network in Africa, promised fast support for critical spare parts.
Results
- Profit Growth: Fuel consumption per rig significantly decreased, directly improving project profitability.
- Increased Collaboration Opportunities: Equipment uptime increased as unexpected downtime caused by malfunctions was reduced. With improved operational costs and reliability, the company became more competitive in bidding for new contracts, successfully securing several long-term service agreements.
- Image Transformation: The company’s market image also shifted from a traditional labor-based service provider to a modern, tech-driven contractor with efficient equipment.
Client Feedback
“For us, choosing a hydraulically operated core drilling machine was a business decision. It helped us control two major costs: fuel and hidden downtime costs. Now, in our proposals, ‘modern and efficient fleet’ is a real strength, not just a buzzword.”
