Quiet Strength Through Intelligent Engineering
The SB40 features Silent Box-type construction that merges structural strength with acoustic efficiency for superior performance.
Noise Reduction Technology (109 dB)
Conventional breakers can exceed 120 dB, making them unsuitable for urban or indoor projects. The SB40's sealed casing and multi-layer damping system isolate impact noise and absorb vibrations, allowing work in noise-restricted environments without compromising power.
Reinforced Structure for Durability
The boxed frame provides superior rigidity compared to open "I-type" bodies. This enhances stability, minimizes torsional stress, and reduces housing fatigue risk for longer service life during continuous heavy-duty demolition.
Intelligent Hydraulic System
Operating on a pure hydraulic platform, the SB40 integrates Guchuan's proprietary auto-frequency adjustment system. It automatically modulates impact rate and force based on material hardness, preventing "blank firing" and improving long-term reliability.
Versatile Applications
Secondary Rock Breaking: Efficiently reduces oversized rocks into manageable sizes
Concrete Demolition: Ideal for foundations, reinforced slabs, and walls
Trenching & Road Work: Breaks asphalt and compacted ground effortlessly
Urban & Indoor Projects: Exceptional for low-noise job sites and renovation works
