SB131 Triangle Excavator Hydraulic Breaker Fits E330 E336 PC300 PC350 SY305 SY335
Our SB131 triangular hydraulic breaker is the industry-leading heavy-duty excavator rock breaker designed to deliver unmatched performance in construction, demolition, quarrying, and road construction projects. This precision-engineered 165mm chisel concrete breaker is specifically calibrated to provide optimal power transfer and efficiency when mounted on 30-35 ton excavators, including the widely used Cat E330, E336, Komatsu PC300, PC350, and Sany SY305, SY335 models.
Featuring advanced nitrogen-assisted percussion technology, this high-impact SB131 demolition hammer delivers consistent, powerful blows while significantly reducing stress on your carrier machine's hydraulic system. The robust open-type triangular design offers superior operator visibility, easier maintenance access, and exceptional durability compared to traditional box-type breakers, making it the most reliable excavator attachment for breaking reinforced concrete, hard granite, asphalt pavement, and building foundations.
- Perfect Hydraulic Matching: Precisely calibrated to match the hydraulic flow and pressure of Cat E330/E336, Komatsu PC300/PC350, and Sany SY305/SY335 excavators, ensuring maximum energy transfer and zero power loss
- Heavy-Duty Triangular Housing: Constructed from premium high-strength alloy steel with full heat treatment, providing exceptional resistance to impact, abrasion, and fatigue during continuous heavy-duty operations
- Advanced Nitrogen Accumulator: Stabilizes hydraulic pressure spikes, protects your excavator's hydraulic system from damage, and enhances overall breaking efficiency
- Superior Impact Performance: Delivers industry-leading blow energy with a frequency of 350-550 blows per minute, enabling 30% faster completion of breaking tasks
- Easy Maintenance Modular Design: Simplifies routine maintenance and reduces costly downtime with quick access to internal components
- Low Vibration Operation: Integrated advanced damping system reduces operator fatigue and complies with strict noise regulations
- Universal Compatibility: Fits other 30-35 ton excavators beyond the specified models
- Lubricate the tool shank every 2 hours of continuous operation
- Inspect hydraulic hoses and connections for leaks daily
- Tighten all bolts and fasteners every 2-3 working days
- Replace the complete seal kit every 500-1000 operating hours (more frequently in highly abrasive conditions)
- Change hydraulic oil every 800 hours or as recommended by your excavator manufacturer
- Moil point chisel: Best for general breaking and hard rock excavation
- Flat chisel: Ideal for concrete demolition and asphalt pavement removal
- Blunt chisel: Perfect for secondary breaking and large boulder reduction
- Cross chisel: Excellent for reinforced concrete and foundation demolition work
- Low nitrogen pressure in the accumulator (should be checked and adjusted monthly)
- Worn internal seals causing hydraulic oil bypass
- Using incorrect hydraulic oil viscosity for the current ambient temperature
- Clogged hydraulic filters restricting oil flow
- Improper hydraulic settings on your excavator
