A rock splitter for excavator is a heavy-duty hydraulic attachment designed to split hard rock, boulders, and concrete structures with controlled, directional force. Mounted directly onto an excavator arm and powered by the machine’s own hydraulic system, this tool replaces traditional and less predictable breaking methods with a quieter, more precise approach. Contractors use it for rock excavation, secondary rock breaking, controlled demolition, and trench work where vibration, noise, or fly-rock restrictions apply. The excavator splitter combines a splitting gun, a hydraulic power system, and an integrated pressure intensifier that amplifies the excavator’s baseline hydraulic output into massive splitting force — all delivered through a specially engineered wedge assembly that maintains its structural shape even after thousands of splitting cycles.
In addition to these large-scale excavator-mounted splitters, YG also sells small, portable hydraulic splitters.

3,800 vs 5,700 Tons: What Your Rock Requires
Splitting force determines what a rock splitter for excavator can handle. The YG series covers the range from 3,800 to 5,700 tons.
3,800 tons (YGM-S200). This handles most quarrying and demolition applications—granite, basalt, limestone, sandstone, and reinforced concrete. It requires a 90- 110 mm drilling diameter and 1,600mm drilling depth. With a 1,000- 1,500 mm drilling gap distance, it covers standard operations efficiently.
5,700 tons (YGM-S280). This is the heavy-duty option for the toughest conditions. It handles ultra-hard rock, massive boulders, and heavily reinforced structures. It requires a 110- 130 mm drilling diameter and 1,700mm drilling depth. The 2,000- 2,500 mm drilling gap distance allows fewer holes per square meter, reducing drilling time and increasing productivity.
The practical rule: For most quarrying and demolition applications, the YGM-S200 with 3,800 tons is sufficient. For ultra-hard rock (compressive strength above 200MPa), massive structures, or operations requiring maximum productivity, the YGM-S280 delivers the extra force needed.
6 Advantages of Rock Splitter for Excavator
- 3800-5700 Tons of Splitting Force: The YG series rock splitter machine delivers 3,800 to 5,700 tons of splitting force—enough to crack granite, basalt, and reinforced concrete. The YGM-S200 handles most quarrying and demolition applications. The YGM-S280 takes on ultra-hard rock and massive structures. More force means faster splitting and fewer cycles per job.
- Integrated Booster System – No External Pump Required: Conventional splitters require a separate hydraulic power pack. The YG series integrates the booster directly into the splitter. Connect to the excavator’s auxiliary hydraulic circuit and start working. No extra equipment on site. No additional maintenance. One less machine to transport and manage.
- 40-50 Second Splitting Cycle: Each splitting cycle takes 40-50 seconds from insertion to fracture. A hydraulic breaker takes 45 minutes to break one cubic meter of hard rock. The splitter cracks it in under one minute. That is 10-15 times faster per boulder.
- 32- 35 mm Crack Width: The excavator rock splitter produces 32- 35 mm crack width—enough to separate rock blocks for removal without secondary breaking. No additional tools. No extra labor. The rock is ready to move.
- 90- 130 mm Drilling Diameter – Low Drill Cost: The YGM-S200 uses 90- 110 mm holes. The YGM-S280 uses 110- 130 mm holes. These diameters work with standard rock drills and DTH hammers. No special tooling. No expensive custom bits. Standard equipment, standard cost.
- Deformation-Resistant Design: The excavator rock splitter maintains its shape through thousands of splitting cycles. The wedge group and cylinder components stay aligned and functional. Less downtime for repairs. Consistent splitting force over the life of the equipment.
Which Model Fits Your Excavator?
The YG rock splitter for excavator is matched to specific excavator classes:
YGM-S200: 20-30 ton excavators, 3,800 tons splitting force, 900kg weight
YGM-S280: 25-40 ton excavators, 5,700 tons splitting force, 1,000kg weight
Check your excavator’s hydraulic capacity. The splitter requires 60-80 MPa working pressure. The excavator’s auxiliary hydraulic circuit must supply this pressure range. Using a splitter that is too heavy for the excavator reduces stability. Using one that is too light underutilizes the machine’s capacity.
The practical difference: The YGM-S200 suits 20-30 ton excavators for medium-to-hard rock excavation, utility trenching, and urban foundation projects. The YGM-S280 is engineered for 25-40 ton excavators for extreme applications—solid granite quarrying, heavy tunnel excavation, and mass reinforced concrete demolition without blasting permits.
YG Manufacturing Quality and Support
Behind every rock splitter for excavator that leaves the YG factory is a rigorous quality control process that starts with material sourcing and ends with full-load performance testing. Each unit undergoes pressure testing, cycle testing, and dimensional verification before it is crated and shipped. The integrated booster system, the forged wedge assembly, and the hydraulic valving all meet YG’s internal durability standards — standards developed over years of serving quarry, demolition, and construction contractors worldwide.
YG also stands behind its equipment with responsive technical support and a ready supply of replacement parts. From the initial model selection consultation through on-site commissioning and ongoing maintenance, the team works directly with contractors to make sure the equipment performs as expected on day one and for years afterward.
Rock Splitter for Excavator Price
If you are still relying on outdated, inefficient breaking methods — or if your current excavator splitter is not keeping pace with production demands — it may be time to evaluate what a purpose-built hydraulic splitting attachment can do for your operation. Whether you work in quarrying, foundation construction, urban demolition, or trench rock removal, there is a YG model matched to your carrier excavator and project requirements.
The YG team can walk you through model selection, hydraulic compatibility, and expected performance for your specific rock type and site conditions. To get started, reach out with your excavator specifications, the rock hardness you work with, and your daily production targets, and you will receive a tailored recommendation and pricing within one business day. A better rock splitter machine is not just an equipment purchase — it is an investment in faster, safer, and more profitable rock breaking.
