A Hydraulic Rock Splitter for Sale is designed for jobs where rock or concrete needs to open along a controlled line. Workers drill holes through the section, insert the splitting gun, and apply hydraulic pressure. The wedge expands inside the hole and pushes against the hole wall, creating a crack without repeated impact.

Hydraulic Rock Splitting Process and Working Principle
The crew first marks the section to separate. In a quarry, holes may follow the boundary of a stone block. On a mountain road, the drilling line may follow the edge of rock that needs to leave the slope.
Hole spacing changes with the material and section size. Dense granite, fractured limestone, and concrete respond differently to internal expansion. After drilling, workers clean the holes and place the splitting gun inside.
Hydraulic oil drives the piston and wedge outward. The wedge presses against the hole wall and creates a crack through the material. After the section opens, the operator releases pressure, removes the gun, and moves it to the next hole.
Hydraulic Splitter Components and Pump Station Options
A complete setup includes the splitting gun, hydraulic pump station, oil hoses, and fittings. One gun suits work where the operator moves from hole to hole. Quarry work may use two or three guns from one pump station when several holes need attention during the same cycle.
Electric and diesel pump stations cover different site conditions. A construction site with 380 V three-phase power can use an electric motor. A remote quarry without grid power can take a diesel pump to the working area.
Hose length also matters. If the pump stays 20 m from the drilling face, the hoses need enough reach for movement between holes without sharp bends or unnecessary tension.
Portable Rock Splitter Applications for Rock and Concrete
A Portable Rock Splitter is used in quarrying, mountain road excavation, foundation work, trenching, tunnel construction, and oversized concrete removal.
On a mountain road through hard limestone, loose material may leave the excavator bucket easily while a solid section beside the slope remains difficult to remove. The crew can drill a row of holes along the planned separation line and use the splitter to open the section from inside.
Concrete work presents a similar case. A foundation may need partial removal while the surrounding structure remains. Holes placed around the removal boundary give the hydraulic force a defined line to follow.
Rock Splitter Operation and Site Requirements
Before using the rock splitter, confirm that the drilled hole meets the requirements of the selected model. YG-250 requires a 42 mm hole with a drilling depth of more than 500 mm. YG-350 and YG-450 both require a 46 mm hole, with drilling depths of more than 700 mm and 900 mm, respectively. After drilling, clean the hole to remove loose debris that could interfere with inserting and operating the splitting gun.
Place the pump station in a position that allows convenient operation and hydraulic connection. Select the hose length according to the actual working area. The hoses should allow sufficient movement while avoiding excessive bending, pulling, or contact with sharp rock surfaces. When multiple splitting guns are used, the hydraulic distribution should be configured according to the number of guns operating at the same time.
During operation, insert the splitting gun into the cleaned hole, start the pump station, and gradually apply hydraulic pressure. The wedge expands outward and presses against the hole wall, causing the rock or concrete to crack along the intended direction. After splitting, release the pressure, remove the splitting gun, and move it to the next hole.
Why Choose YG Hydraulic Rock Splitter for Sale
YG Machinery has an engineering team that supports equipment selection, production, testing, and technical documentation. Before shipment, each hydraulic rock splitter is checked for hydraulic operation, component assembly, and overall working condition. The production process follows defined quality inspection procedures rather than relying only on final assembly checks.
For markets that require compliance documentation, YG can provide relevant certificates and technical documents, including CE certification where applicable. Product specifications, electrical information, hydraulic data, and operating instructions can also be prepared according to the equipment configuration and destination requirements.
After delivery, YG provides technical support for installation, operation, troubleshooting, and spare parts. If a hydraulic component or splitting gun requires replacement, the customer can provide photos, videos, or equipment information so the technical team can help identify the part and arrange the corresponding solution.
FAQ
1. How much does it cost?
The quotation includes the splitter model, pump station, gun quantity, hoses, and destination-related shipping costs.
2. How many days does it take to ship?
The shipment date follows the selected configuration and factory schedule. Standard and multi-gun systems may have different production times.
3. What happens if the splitter breaks?
The pump, hoses, fittings, and splitting gun can be checked separately. YG can identify the relevant component and provide troubleshooting or replacement support.
4. How many guns can one diesel pump run?
One diesel pump station can run at least six splitting guns. The actual configuration depends on the pump flow, working pressure, hydraulic distribution, hose length, and whether all guns operate simultaneously. For six-gun operation, YG configures the pump station and hydraulic system according to the required flow and working arrangement.
