For 20–65 Ton Excavators | Integrated Drilling & Hydraulic Rock Splitting | No Explosives Required


Already own an excavator and need an efficient solution for hard rock excavation? The YG drilling and splitting excavator attachment adds hydraulic rock drilling and splitting capabilities to your existing machine, eliminating the need to purchase a separate drilling rig for these operations.
Designed for 20–65 ton excavators, this integrated hydraulic rock drill and splitter attachment supports both vertical and horizontal drilling. After drilling, the mast rotates 90° to position the hydraulic splitting lance inside the hole. This allows operators to switch from drilling to splitting without removing the complete attachment.
It is a practical solution for quarrying, mining, foundation excavation, tunnel construction, and other projects where controlled rock breaking is required.
Key Benefits
- Two operations in one attachment: Drill holes and split rock using the same excavator-mounted system.
- 90° mast rotation: Switch between drilling and splitting without changing the complete attachment.
- 20–65 ton excavator compatibility: Select a model according to your existing machine.
- Controlled rock breaking: Split rock hydraulically without explosives.
- Lower equipment investment: Expand your excavator’s capabilities without purchasing a separate drilling rig.

Match the Attachment to Your Existing Excavator
Choosing the right hydraulic rock drill and splitter attachment starts with your carrier machine. Excavator operating weight, hydraulic flow, working pressure, and mounting configuration all affect compatibility and performance.
YG offers configurations for excavators in the 20–65 ton range.
| Model | Compatible Excavator Weight | Key Specifications |
|---|---|---|
| YG1000 | 20–36 tons | Splitting force up to 12,000 tons |
| YG1500 | 36–48 tons | 30 kW drilling power; 135 mm drilling diameter; splitting force up to 15,000 tons |
| YG2000 | 48–65 tons | Splitting force up to 30,000 tons |
Final configuration depends on the selected model and project requirements.
What Should You Confirm Before Ordering?
To ensure the attachment matches your excavator, provide:
- Excavator model and operating weight
- Hydraulic flow and working pressure
- Mounting interface and installation requirements
- Rock type and required drilling diameter and depth
- Project application and expected working conditions
These details help YG recommend a suitable excavator rock splitting attachment for your machine rather than a generic configuration.
Why Choose a Drilling and Splitting Attachment Instead of a Rock Breaker?
A hydraulic rock breaker uses repeated impact to fracture rock. A drilling and splitting excavator attachment first drills a hole and then applies hydraulic force through a wedge mechanism to split the rock.
| Feature | Drilling and Splitting Attachment | Hydraulic Rock Breaker |
|---|---|---|
| Working method | Drilling followed by hydraulic splitting | Repeated impact |
| Drilling capability | Integrated hydraulic drill | No integrated drilling system in a conventional breaker |
| Rock-breaking control | Splitting direction influenced by hole positioning and arrangement | Breaks rock through repeated impacts |
| Typical applications | Controlled rock excavation and restricted blasting areas | Demolition and general rock breaking |
The key advantage is the combination of drilling and splitting in one attachment. For contractors who regularly excavate hard rock and need a controlled breaking method, this can expand an existing excavator’s capabilities without requiring a separate drilling rig.

Applications of Hydraulic Rock Drill and Splitter Attachments
Quarrying and Mining: Drill and split hard rock into manageable sections for excavation, loading, or crushing. This method can be useful in areas where blasting is restricted or a more controlled breaking process is required.
- Foundation Excavation: Remove bedrock during basement, foundation, and deep excavation work. Hydraulic splitting can be an alternative to blasting near existing buildings and underground utilities.
- Tunnel Construction: Perform suitable rock drilling and splitting operations where working space, access, and excavation geometry require a controlled approach to rock removal.
- Road Construction: Break rock along road cuts, drainage routes, and foundation areas where conventional blasting may be impractical.
- Excavation Near Existing Structures: Hydraulic splitting avoids explosive shock waves and can reduce blast-related disturbance. Actual vibration and noise levels depend on the equipment, geology, and operating conditions.
What Affects Rock-Splitting Efficiency?
Actual productivity depends on more than the attachment’s maximum splitting force.
- Rock conditions: Hardness, natural fractures, and geological structure influence drilling speed and splitting performance.
- Hole dimensions: Drilling diameter, depth, spacing, and orientation affect how effectively the rock fractures.
- Excavator compatibility: Suitable hydraulic output and stable positioning help maintain consistent operation.
- Working cycle: Positioning, drilling, mast rotation, splitting, and material removal all contribute to total production time.
For an accurate equipment recommendation, YG can assess your excavator specifications, rock type, and project requirements.
Maintenance and Technical Support
Regular maintenance helps keep your drilling and splitting excavator attachment operating efficiently.
- Inspect drill bits, drill rods, and wear components regularly.
- Check hydraulic hoses, fittings, seals, and connections for leaks or damage.
- Inspect the splitting lance and wedge mechanism for abnormal wear.
- Check the mast rotation mechanism and mounting structure.
- Follow the manufacturer’s instructions for hydraulic oil, lubrication, and routine servicing.
YG can provide configuration guidance, operating instructions, and support with maintenance and replacement parts.


FAQ about Hydraulic Rock Drill and Splitter Attachment
1. Can the attachment drill both vertically and horizontally?
Yes. The attachment supports vertical and horizontal drilling. The appropriate configuration depends on the project layout and working conditions.
2. How does the attachment switch from drilling to splitting?
After drilling, the mast rotates 90° to position the hydraulic splitting lance inside the hole. This eliminates the need to remove the complete attachment between operations.
3. Can hydraulic splitting replace explosive blasting?
Hydraulic splitting is an alternative for projects where blasting is restricted or undesirable. It uses a hydraulic wedge mechanism rather than explosives, making it suitable for many controlled rock excavation applications.
4. What happens if the wedge gets stuck?
This is rare. The hydraulic system has a reverse function. It can retract the wedge with full power. For very sticky materials, YG advises reducing the splitting force slightly before starting the cycle.
5. What information is needed for a quotation?
Provide your excavator brand and model, operating weight, hydraulic flow and pressure, rock type, required hole dimensions, and project application. YG can use this information to recommend a suitable attachment and provide a quotation.
