Unpacking the Technology: Features & Advantages

1. Advanced "Silent Boxer" Design
Unlike traditional triangle breakers, the box-type structure of the SB30/GCB53 offers superior durability and noise dampening. The 109 dB noise level is a significant advantage for urban construction, indoor demolition, and environmentally sensitive sites where strict noise regulations apply. This design reduces vibration, leading to less operator fatigue and lower stress on the excavator's boom and arm.

2. High Impact Energy & Optimized Frequency
With a powerful 406 Joule impact force and a variable impact rate of 600-1100 blows per minute (BPM), the GCB53 delivers a perfect balance of brute force and speed. This means you can tackle concrete, rocks, and asphalt efficiently, breaking material faster while maintaining control for precise work.

3. Superior Hydraulic System Compatibility
Designed to work seamlessly within a pressure range of 90-120 Bar and a flow of 25-50 l/min, this breaker ensures optimal performance from your compact excavator without requiring excessive system modifications. The efficient hydraulic circuit minimizes heat generation, extending the lifespan of the breaker and your carrier's hydraulic system.

4. Robust Construction & Auto-Frequency Control
Leveraging our in-house R&D capabilities, the SB30/GCB53 incorporates an intelligent, auto-frequency control system. This technology automatically adjusts the impact rate based on the hardness of the material, preventing "blank firing" and maximizing energy transfer on every blow. This results in higher efficiency, reduced wear, and longer component life.

5. Unmatched Value with OEM-Quality Assurance
As a direct manufacturer, Guchuan provides the same rigorous quality standards you would expect from top-tier Korean and Japanese brands like Soosan, MSB, and Furukawa, but at a more competitive price. The SB30/GCB53 is our high-quality alternative to models like the Soosan SB30/GCB50, offering you exceptional performance without the premium cost. We back our confidence with a robust 12 to 18-month warranty.
