| High Light | SB40 Hydraulic Breaker for excavators ，Precision crushing hydraulic breaker ，Efficient excavator hydraulic breaker | ||
Unleash heavy-duty crushing power with the SB40 hydraulic breaker—designed for speed, durability, and versatility in tough excavation and demolition tasks. This high-performance breaker integrates advanced hydraulic technology, delivering consistent impact force and low maintenance costs. Ideal for 4-7 ton excavators, its 68mm chisel penetrates through rock, concrete, and asphalt with ease. Engineered for long-term reliability, the SB40 features hardened steel components, optimized vibration reduction, and smart lubrication for extended tool life. Whether in mining, construction, or road repair, this breaker boosts productivity while saving time and costs. Choose the SB40 for unmatched efficiency and expert support—your go-to solution for challenging crushing jobs.
The SB40 operates on a hydraulic piston system: pressurized oil drives the piston to strike the chisel, generating high-frequency impacts. The nitrogen accumulator absorbs shockwaves, stabilizing performance. The 68mm chisel’s precision geometry ensures deep penetration with minimal energy loss. The sealed lubrication system prevents debris intrusion, maintaining internal cleanliness for reliable 24/7 operation.
Q: Can the SB40 be used with excavators outside the 4-7 ton range?
A: Not recommended. Incompatible weights may cause performance issues.
Q: How often should lubrication be checked?
A: Daily checks are advised; refill grease every 50-100 hours of use.
Q: Is the SB40 suitable for underwater demolition?
A: No. It’s designed for dry environments only.
Q: What’s the typical lifespan of the chisel?
A:约600-800 hours (varies by material hardness & maintenance).
Q: Does the breaker include noise reduction features?
A: Yes, integrated vibration dampers keep noise ≤110 dB(A).
