YG Machinery supplied a rock splitter machine to a tunnel construction project in Canada. Blasting was not allowed due to safety regulations. The contractor needed a quiet, vibration-free way to break hard rock in a confined space.
The YG hydraulic rock splitter solved the problem. It splits rock in 10-15 seconds per hole. No blasting. No vibration. The project stayed on schedule.
Customer Background
A construction contractor in Canada was working on a tunnel excavation project. The tunnel passed under an urban area. Blasting was prohibited. Vibration could damage nearby buildings. Noise restrictions applied during daytime hours.
Traditional rock breaking methods would not work. Manual hammering was too slow. Hydraulic breakers caused too much vibration. The contractor needed a concrete splitter that could work quietly and precisely in a confined space.
Why a Tunnel Project Needed a Rock Splitter Machine?
The tunnel working space was narrow. Only small equipment could fit. Blasting was not an option. Any vibration could crack the surrounding rock structure and cause collapses.
The contractor had three requirements. First, the machine must produce no vibration. Second, it must work quietly. Third, it must split hard rock quickly.
A hydraulic rock splitter met all three. It uses hydraulic pressure to push wedges into a drilled hole. The wedges expand and split the rock from inside. No vibration. Low noise. Fast splitting time.
How the Contractor Found YG Machinery?
The project manager searched online for a rock splitter machine for sale. He found several suppliers. Some offered cheap machines with poor quality. Others had good products but slow delivery.
He found YG Machinery’s website. The YG-350 model caught his attention. It had 800 tons of splitting force and could handle 46mm drill holes. The weight was only 250kg, easy to move in a tunnel.
He submitted an inquiry. Our sales manager replied within a few hours. He asked about rock hardness, tunnel width, and daily splitting volume. The contractor explained they needed to split granite with a hardness of over 100MPa. The tunnel width was only 3 meters.
The sales manager recommended the YG-350 hydraulic rock splitter with a diesel power pack. He sent videos of the machine splitting hard rock in similar projects. He explained how the wedge system works and how to maintain it.
James placed an order for two units.
YG-350 Rock Splitter Machine
Here is what the contractor received:
| Specification | YG-350 |
| Wedge length | 350mm |
| Piston stroke | 90/220mm |
| Drilling depth | >700mm |
| Drilling diameter | 46mm |
| Crack width | 10-20mm |
| Splitting time | 10-15 seconds |
| Splitting force | 800 tons |
| Weight | 250kg |
| Power | Diesel power pack, 10-60Mpa adjustable |
This hydraulic concrete splitter uses a diesel power pack. Pressure adjusts from 10 to 60Mpa. The wedge set has one middle wedge and two side wedges. High-pressure oil pushes the middle wedge forward. The side wedges spread outward and split the rock.

Core Features of This Hydraulic Rock Splitter
No vibration. Zero impact. No shaking. The machine splits rock from inside using hydraulic pressure. Safe for tunnels and near buildings.
Quiet operation. Noise level is very low. The contractor worked during daytime without disturbing nearby residents.
Fast splitting time. Each split takes 10-15 seconds. Workers drill a hole, insert the wedges, and split. Repeat the process. Progress is fast.
Portable design. The machine weighs 250kg. Two workers can move it around the tunnel. No crane needed.
No dust. Dry splitting process. Zero dust in the air. Good for workers’ health in confined spaces.
Precise control. Operators can control the splitting direction. The rock breaks exactly where needed. No damage to surrounding rock.
Low maintenance. Simple parts. The wedges are made of forged and heat-treated steel. They do not break easily under high pressure.
This portable rock splitter is built for tough jobs in tight spaces.
Implementation and Results
The two YG-350 rock splitters arrived at the Canadian site within five weeks. YG provided remote training. The team learned to operate the hydraulic rock splitter in one day.
The working process was simple:
- Drill a 46mm hole 700mm deep into the rock
- Insert the wedge set into the hole
- Start the diesel power pack
- High-pressure oil pushes the middle wedge
- The wedges expand and split the rock in 10-15 seconds
- Move to the next hole and repeat
The results were clear:
- Splitting time. Each split took 10-15 seconds. The team completed daily targets ahead of schedule.
- No vibration. Sensitive instruments near the tunnel showed no movement. Nearby buildings were safe.
- No noise complaints. The quiet operation allowed daytime work. Neighbors did not complain.
- Precise splitting. The rock broke exactly where planned. The tunnel walls stayed stable.
- Low maintenance. The machines ran for weeks without any repairs.
The contractor finished the tunnel section on time. Safety records were clean. No accidents. No delays.
Customer Feedback
James told us:
“The YG rock splitter machine worked perfectly in our tunnel. No vibration. No noise. The splitting time was fast. We finished on schedule. I would buy from YG again.”
For cutting concrete walls, a hydraulic wall saw offers precision cuts with low vibration.
