Guideline for selecting suitable hydraulic breaker for your excavator:
When matching your excavator model with hydraulic breakers (such as the SB43/HWX750 mentioned previously), understanding the specific weight distribution is crucial for ensuring the correct match of hydraulic flow and pressure.
- Hydraulic Flow Matching: This ensures the hydraulic breaker maintains a high impact frequency without causing the hydraulic oil to overheat.
- Structural Stability: The SB43 hydraulic breaker (including the housing) weighs approximately 400kg. When mounted on a 6-8 ton excavator, it provides sufficient downforce for breaking while maintaining machine stability, preventing tipping risks during side-loading operations.
Application Scenarios: Pairing these excavators with the SB43 hydraulic breaker is considered a “Golden Combination.” It is widely utilized in municipal maintenance, indoor demolition, and rock breaking in landscaping projects.
