In May 2025, YG Machinery received an inquiry from a construction contractor in Algeria who was working on a tunnel excavation project. The customer needed a reliable solution to break hard rock in a confined environment where traditional blasting methods were not allowed.
Due to strict safety regulations and environmental concerns, the client was specifically looking for a hydraulic rock splitter machine that could deliver high efficiency without causing vibration, noise, or structural damage.
After detailed communication, our sales manager provided a complete solution based on the customer’s working conditions and project requirements.

Customer Requirements and Challenges
During the initial discussion, the customer highlighted several key challenges:
- Blasting was prohibited due to safety restrictions
- The tunnel working space was narrow and limited
- High efficiency was required to meet tight deadlines
- The surrounding rock structure needed to remain stable
Traditional rock breaking methods such as manual hammering or blasting could not meet these requirements. Therefore, the customer needed a rock splitting machine that was safe, precise, and suitable for confined spaces.
YG Machinery Solution
Based on the project conditions, we recommended our hydraulic rock splitter machine, which is specially designed for non-blasting rock and concrete splitting.
This machine consists of a hydraulic power unit and a splitting gun. It uses ultra-high pressure hydraulic oil (up to 60MPa) to generate enormous splitting force, allowing rocks to be split from the inside in a controlled manner.
Compared with traditional methods, this rock splitting machine offers:
- No vibration or shock
- Low noise operation
- High splitting efficiency
- Precise crack control
For this tunnel project, we recommended our hydraulic rock splitter machine, also available as a drilling-and-splitting integrated machine. This advanced solution combines drilling and splitting in one unit, allowing operators to drill holes and split rock efficiently without switching equipment, saving time and labor.
Working Process on Site
After receiving the machine, the customer quickly put it into operation. The working process was simple and efficient:
- Drill holes with a diameter of 42mm and a depth of more than 500mm
- Insert the hydraulic splitter into the drilled holes
- Start the hydraulic power unit
- Generate splitting force to break the rock
Each splitting process took only 10–15 seconds, significantly improving work efficiency.
Because the hydraulic rock splitter machine works without vibration, operators were able to observe the splitting process at close range, ensuring better control and safety.
Project Results and Benefits
After using the equipment on site, the customer achieved excellent results:
✔ Improved Efficiency
The splitting speed was much faster compared to manual methods, helping the project stay on schedule.
✔ Safe Operation
No blasting was required, eliminating safety risks and simplifying the construction process.
✔ No Environmental Impact
The machine produced no dust pollution, harmful emissions, or excessive noise, making it suitable for environmentally sensitive areas.
✔ Precise Splitting
The customer was able to control the direction and size of cracks, reducing unnecessary damage to surrounding rock.
✔ Reduced Labor Cost
The easy operation and high efficiency reduced the need for excessive labor.
Customer Feedback
After several weeks of use, the customer shared positive feedback:
“This hydraulic rock splitter machine works very efficiently in our tunnel project. It is safe, easy to operate, and much better than traditional methods. We are very satisfied with its performance.”
This successful cooperation further demonstrates the reliability of YG Machinery in providing professional rock splitting solutions.
Application Scenarios
This hydraulic rock splitter machine is widely used in:
- Tunnel excavation projects
- Mining and quarry operations
- Concrete structure demolition
- Road and bridge construction
- Underground engineering
