SB30 Hydraulic Breaker: The Ultimate Attachment for 4-7 Ton Excavators

Engineered for Superior Performance: Technology & Design

The SB30 isn't just a tool; it's a system built on Guchuan's core technological expertise.

Open-Type Robust Design: The classic, proven open-side design ensures excellent heat dissipation, reduces wear on internal components, and simplifies maintenance. This architecture allows for quick visual inspection and easier clearing of potential debris, maximizing uptime on your job site.
Guchuan's Auto-Frequency Tuning Technology: Leveraging our in-house R&D capabilities in auto-frequency tuning, the SB30 intelligently adapts its impact rate and power based on material hardness. This proprietary hydraulic system optimizes energy transfer, delivering maximum impact force while protecting both the breaker and your carrier from harmful vibrations and backpressure.
Pure Hydraulic Power: As a manufacturer with full pure hydraulic breaker capability, we ensure the SB30 operates with smooth, consistent power directly from your excavator's hydraulic system. This eliminates the inefficiencies of pneumatic or other hybrid systems, providing faster cycle times and lower operational costs.
Optimized for Your Machine: With precise parameters for pressure (110-140 bar) and flow (40-70 L/min), the SB30 integrates seamlessly with your 4-7 ton excavator's hydraulics. This perfect match ensures you get the highest possible productivity without straining your carrier, a key consideration for operators searching for "best hydraulic breaker for 5 ton excavator" or "efficient breaker for Kubota U35."

Key Advantages & Why Choose the SB30

Unmatched Power-to-Weight Ratio: At approximately 300 kg, the SB30 delivers a formidable impact force for its class, making it one of the most powerful hydraulic hammers for mini excavators.
Enhanced Durability & Longevity: Precision-machined components, high-grade accumulator technology, and specialized heat-treated steel in critical wear areas (like the housing and bushings) result in exceptional service life, reducing total cost of ownership.
High Efficiency & Lower Operating Costs: The high impact rate (up to 900 bpm) combined with optimized energy use means you break more material faster, saving on fuel and labor time. Its efficiency is a direct answer to searches for "high productivity mini excavator hammer."
Versatility in Applications: The 68mm chisel diameter is ideal for a wide range of tasks. Whether you're in construction, landscaping, utility work, or mining, the SB30 handles it all—from breaking frost, asphalt, and concrete to trenching in rocky soil.
Easy Maintenance & Global Support: The design prioritizes serviceability. With standard tooling and readily available spare parts (including a range of compatible moil points and chisels), maintenance is straightforward. Backed by Guchuan's global supply chain, support is never far away.

The Guchuan SB30 is the expert's choice for:
- - Demolition of small concrete structures, slabs, and foundations.
  - Trenching and excavation in rocky or compacted soils.
  - Road repair and asphalt breaking.
  - Boulder breaking in landscaping and quarry operations.
  - General construction and utility projects requiring reliable, medium-impact force.
