You have a boulder in the way. Or a concrete foundation to remove. Blasting is not allowed – too close to buildings. A breaker is noisy and shakes everything. What if you could split rock from the inside, quietly and safely, without any vibration?
That is exactly what a rock splitter hydraulic does. You drill a hole, insert the splitter, and apply hydraulic pressure. The splitter expands inside the hole, cracking the rock along natural lines. No explosion. No flying debris. No permits. YG offers three models: YG-250, YG-350, and YG-450. Wedge lengths from 250mm to 450mm. Splitting force from 500 tons up to 800 tons. The machine has two parts: a hydraulic power pack (electric or diesel) and the splitting tool (枪头). You can run up to 6 splitting guns from one pump.

How Does A Rock Splitter Work?
Step 1 – Drill the hole. Use a rock drill to make a hole with the correct diameter and depth. The hole must be clean and straight.
Step 2 – Insert the splitter. Place the splitting gun into the hole. The wedge is between two counter‑wedges.
Step 3 – Apply hydraulic pressure. The hydraulic pump sends pressurised oil to the cylinder inside the gun. The piston pushes the wedge forward. The wedge forces the two counter‑wedges outward against the hole walls. The pressure builds until it exceeds the rock‘s tensile strength. The rock cracks from the inside out.
The whole split takes 10‑15 seconds. No vibration. No noise beyond the hydraulic pump.
Why Choose A Hydraulic Rock Splitter Over A Breaker Or Blasting?
| Method | Problems | Rock Splitter Advantage |
| Blasting | Permits required, fly rock, shock waves, noise, vibration | No permits needed. Safe. |
| Hydraulic breaker | Loud, shakes excavator, dust, wears out tools | Quiet, no dust, no vibration |
| Jackhammer | Slow, labour-intensive, limited depth | Splits in 10-15 seconds |
Core Components
The rock splitter hydraulic system has two main parts:
1. Hydraulic pump station – Provides pressurised oil. Two types:
- Electric pump – For sites with power access.
- Diesel pump – For remote sites or where electricity is not available.
2. Splitting gun – The tool that goes into the hole. Contains the piston, wedge, and counter‑wedges. Available in three wedge lengths (250, 350, 450mm). One pump can power up to 6 splitting guns. For 2 or more guns, you need a flow divider to distribute oil evenly.
Total system price = Pump station + Splitting gun(s) + Flow divider (if 2+ guns) + Hoses + Wear parts (the two wedges/expanding parts).
Maintenance And Care
Daily checks: Check hydraulic oil level, inspect hoses and connections, and examine the splitting gun for wear. Fix any problems immediately.
Regular maintenance: Change hydraulic oil periodically. Clean the equipment. Lubricate moving parts.
Storage: Keep the equipment in a dry, ventilated place. Avoid moisture and direct sunlight.
Frequently Asked Questions
Space holes about 300‑500mm apart along the splitting line. For a 2m boulder, you might need 4‑6 holes. Insert the gun, split, and move to the next hole.
Yes, but rebar will not split – it will bend. The rock splitter cracks the concrete around the rebar. Then you cut the rebar with a torch or shear.
Yes, but you need a flow divider. One pump station can power up to 6 splitting guns. For more than 6, add another pump.
Operation is simple, but training is recommended – especially on safety, drilling depth, and pressure management. YG provides a manual.
Split Rock Safely And Quietly With YG
A rock splitter hydraulic is the safest and most environmentally friendly way to break rock and concrete in sensitive areas. No blasting permits. No vibration damage to nearby structures. No dust clouds. YG offers three models with wedge lengths from 250mm to 450mm and splitting forces from 500 to 800 tons. The system is simple: a hydraulic pump (electric or diesel) and splitting guns. One pump can power up to 6 guns. The operation takes 10‑15 seconds per split. The machine is easy to maintain – just check oil, inspect hoses, and store properly.
YG has shipped rock splitters to quarries, construction sites, and tunnel projects worldwide. Contact YG with your rock type, typical boulder size, and site power availability. They will recommend the right rock stone splitter model, pump type, and hose length – and provide a detailed quote. Stop blasting – start splitting.
