The rock breaking machine is designed for modern excavation projects that require high efficiency, safety, and precision in hard rock environments. Instead of relying on explosives or high-impact breakers, this system uses controlled hydraulic splitting technology to fracture rock from inside the structure.
YG Machinery develops this equipment for mining, quarrying, tunnel excavation, and urban foundation projects where blasting is restricted or unsafe. By integrating drilling and splitting functions into a single excavator-mounted system, it reduces equipment dependency while improving productivity and operational control.
This solution is especially valuable in projects where safety regulations are strict, and construction timelines are tight.

Rock Breaking Machine Integrated Excavator Drilling Splitting System for Unified Construction Workflow
This system transforms a standard excavator into a complete rock processing platform by combining drilling and splitting functions into one attachment. It eliminates the need for multiple machines and simplifies field operations.
Key system advantages:
- Direct integration with the excavator hydraulic system
- One-machine workflow from drilling to rock splitting
- Reduced setup time between working steps
- Compact structure improves stability in narrow sites
- Compatible with multiple excavator tonnage levels
This design improves coordination efficiency on complex construction sites and reduces downtime caused by machine switching.

Digger Rock Breaker for Flexible Multi-function Excavation Applications
The digger rock breaker enhances excavator versatility by allowing multiple working modes within one system. Operators can switch between drilling, splitting, and breaking depending on site conditions.
Key advantages:
- Excavator multifunction attachment reduces equipment cost
- Supports different rock hardness levels
- Improves excavator utilization rate across projects
- Reduces need for separate breaking tools
- Enhances operational flexibility on mixed terrain
This flexibility helps contractors handle different job requirements with a single machine system.
Application Scenarios of Rock Breaking Machine System
This equipment is widely used in engineering environments where blasting is restricted or precision rock removal is required.
Typical applications:
- Quarry secondary rock breaking operations
- Tunnel excavation and underground engineering
- Highway and railway foundation work
- Urban building demolition projects
- Mining block splitting operations
- Restricted or safety-controlled construction zones
Its adaptability ensures stable performance across both large-scale and precision engineering projects.


Case Study: Rock Excavation in Kuala Lumpur, Malaysia
- Project Type: High-Rise Building Foundation Excavation & Trenching
- Location: Kuala Lumpur, Malaysia
- Geological Condition: Highly weathered to solid hard granite (Compressive strength: 120–150 MPa)
- Equipment Deployed: YG Hydraulic Rock Breaking Machine mounted on a 30-ton Caterpillar Excavator (equipped with a hydraulic drilling rig attachment)
Project Background & Challenge
A local civil engineering contractor in Kuala Lumpur was awarded a major commercial foundation project located within 50 meters of residential apartments and underground metro lines. The excavation required breaking over 18,000 m³ of hard granite.
The project faced two critical hurdles:
- Strict Regulatory Restrictions: Local environmental authorities strictly prohibited explosive blasting due to vibration risks to adjacent structures and underground infrastructure.
- Low Efficiency of Hydraulic Breakers: Using traditional hydraulic hammers proved extremely slow (achieving less than 15–20 m³ per day), while causing excessive noise complaints, heavy fuel consumption, and severe wear on the excavator’s hydraulic arm.
YG’s Solution & On-Site Execution
The contractor selected YG’s Excavator Hydraulic Rock Breaking Machine to overcome the hard rock challenge safely and quietly. The process was carried out in three simple steps:
- Drilling: Holes with a diameter of 110 mm and a depth of 1.5–1.8 meters were drilled along the target cleavage lines.
- Splitting: The operator positioned the hydraulic wedge cylinder into the pre-drilled hole directly from the excavator cab. Delivering over 5,000 tons of splitting force, the machine expanded and cracked the solid granite within 30 to 45 seconds.
- Secondary Clearing: The split rock blocks were easily pried apart and loaded by a standard bucket excavator.
Results & Economic Benefits
- Daily Output: Rock extraction speed increased significantly from 18 m³/day (with hydraulic hammer) to over 120 m³/day.
- Noise & Vibration Control: Operating noise remained below 75 dB, and ground vibration was nearly zero, fully meeting local urban environmental standards.
- Cost Savings: Reduced overall fuel consumption by approximately 40% compared to continuous hammer impact, while cutting teeth and maintenance expenses by 35%.
- Schedule: The rock excavation phase was completed 20 days ahead of the contract schedule, saving the client over $35,000 in labor and equipment rental costs.
“YG’s rock breaking machine saved our project in Kuala Lumpur. It allowed us to clear hard granite right next to occupied residential buildings without disturbing the neighbors or damaging nearby underground utilities.” — Project Manager, Civil Construction Co., Malaysia

Hydraulic Rock Breaker for Controlled Non-explosive Rock Demolition Operations
The hydraulic rock breaker replaces blasting methods with internal hydraulic pressure expansion. This allows rock to be fractured along controlled lines without vibration or shock impact.
Main benefits:
- Non-explosive rock-breaking excavator operation improves safety
- Zero vibration impact protects surrounding structures
- Suitable for urban, tunnel, and sensitive construction zones
- Reduces regulatory approval time for demolition projects
- Lower environmental and noise impact compared with blasting
This makes it ideal for contractors working in regulated or densely populated environments.
Rock Drilling Splitting Machine for Precise Hydraulic Fracture Control System
The rock drilling splitting machine uses a two-step controlled process: precision drilling followed by hydraulic expansion. This ensures predictable fracture direction and reduces unnecessary material waste.
Working process:
- Step 1: Drill an accurate borehole into rock
- Step 2: Insert hydraulic splitting unit
- Step 3: Apply controlled pressure (60–80 MPa)
- Step 4: Internal expansion creates crack propagation
- Step 5: Rock separates along designed fracture lines
This method increases efficiency while maintaining structural control, especially in granite, basalt, and reinforced concrete.


How to Choose the Right Rock Breaking Machine System
Selecting the correct model depends on project conditions and excavator capacity.
Key selection factors:
- Rock hardness and geological structure
- Excavator tonnage compatibility
- Required drilling depth and diameter
- Daily production targets
- Site safety and environmental restrictions
- Choose S200 for medium work, S280 for heavy-duty projects
