YG hydraulic rock drill and splitter is made for fast drilling and safe rock cracking without blasting. It is a good choice for road work, foundations, tunnels, and quarries where noise and vibration must be controlled. With the right hole plan, you can break rock in a clear line and get cleaner pieces for loading or crushing.

Hydraulic Rock Drill And Splitter For Non-Blasting Rock Breaking
Modern urban zoning and environmental regulations increasingly prohibit the use of traditional explosives. Obtaining blasting permits involves costly logistical delays, while ground vibration poses severe structural risks to adjacent infrastructure.
The YG excavator-mounted hydraulic drill-and-split method bypasses these regulatory bottlenecks entirely, delivering predictable daily output, enhanced jobsite safety, and zero risk of structural over-break.
Critical Engineering Use Cases:
- Strict Ultra-Low Noise Zones: Ideal for metropolitan infrastructure, utility trenching, and night shifts in residential sectors.
- Micro-Vibration Control: Prevents structural micro-fractures when operating near historical buildings, concrete bridges, high-pressure gas lines, and underground utility pipes.
- Controlled Directional Cracking: Allows engineers to dictate the exact failure plane of the bench, ensuring clean vertical walls and optimized rock fragmentation.
Advanced Working Principle: Capitalizing on Rock Tensile Weakness
The mechanical process operates on a highly efficient, two-stage cycle utilizing a single excavator attachment:
- Stage 1 (Percussive Drilling): The high-frequency hydraulic drifter delivers a 300J impact energy at 17.5 MPa, rapidly boring a 43–115mm diameter hole up to 1700mm deep into the rock face.
- Stage 2 (Hydraulic Splitting): The heavy-duty wedge assembly translates the excavator’s 40 MPa hydraulic pressure into a massive 5000T rated splitting force inside the pre-drilled cavity.
The Engineering Logic: Geologically, natural rock mass exhibits immense compressive strength but very low tensile strength (it resists being crushed but splits easily when pulled apart from the inside). By driving the counter-wedges outward, the splitter exploits this inherent physical weakness, forcing a structural failure within 3 minutes.
On-site productivity relies heavily on the geometric relationship between the hole depth and the free face. If the spacing is too wide, the tensile stress fields will not intersect, causing the crack to stall. If too close, cycle times and fuel consumption rise inefficiently.
Excavator Rock Drill And Splitter For 25T Carriers
An excavator rock drill and splitter lets you keep the whole job at one machine. You do not need to move small tools and power packs many times. This is useful on slopes, long trench lines, and large rock areas.
Before you buy, check these points with your supplier:
- Excavator match: carrier size, pressure, and available oil flow
- Working depth: your target hole depth and the rock layer thickness
- Job type: open quarry, narrow trench, or inside demolition
When the attachment and excavator are well matched, you get stable drilling speed and stable splitting results. This is what most contractors want most: output you can predict.
Integrated Rock Drill And Splitter for Faster Cycles
An integrated rock drill and splitter is a drilling and splitting all-in-one machine. It reduces tool change time. The operator can drill, then split, then move to the next point with a smooth cycle. This helps when you have a tight schedule.
It also makes work easier for new operators because the process is clear:
- Drill to the planned depth
- Split along the planned crack line
- Remove the broken pieces and continue
How To Plan Holes for Clean Cracks
A good hole plan is the key to smooth splitting. Even a strong splitter cannot give good results if holes are placed without a plan. For most jobs, start with a straight crack line, then adjust after you see the first split.
Simple tips that help on many working sites:
- Keep the hole line straight, and keep spacing as even as possible
- Drill to a stable depth so the crack goes through the full rock layer
- When rock is very hard, use smaller spacing and test first
If you work with mixed rock layers, you may need to change the plan by area. This is normal. After one or two test lines, the best spacing becomes clear.
Maintenance That Keeps Output Stable
Daily checks are simple but important. Clean oil, good seals, and correct pressure protect your investment. Replace worn parts on time, especially seals and wear parts around high-pressure areas. Also keep air compressor parts in good condition, because the unit includes an air compressor with 8m³/5bar displacement.
When performance drops, start with basic checks: oil level, filter status, hose condition, and quick couplers. Many “weak power” issues are caused by flow loss, not by the main unit itself.
