We supply not only hydraulic cconcrete breaker for backhoe loader JCB3CX JCB3DX CAT426F2, but also hydraulic breaker piping kits for backhoe loader JCB3CX JCB3DX CAT426F2.
The HWX680 (most notably the SB40) is a highly popular hydraulic breaker designed for mini and midi excavators in the 4.0 to 7.0-ton range.
Specification of HWX680
weight of hydraulic breaker 300kg
length 110cm
Working pressure 110-160 kg/cm²
Oil Flow 40-70 L/min
Impact Rate 500-900 bpm
Oil hose dia. 1/2 inch
suits for excavator and backhoe loader 4-7 ton
Why it stands out:
Gas-Oil Percussion: Uses nitrogen gas in the back head to increase impact force while reducing the demand on the excavator’s hydraulic system.
Simplified Design: Features fewer moving parts than competitors, which reduces maintenance costs and potential fail points.
Vibration Damping: The Silenced (Box) type uses urethane cushions to protect the excavator arm and reduce operator fatigue.

Important Considerations Before Buying
Hydraulic Plumbing: Ensure your excavator has “Excavator Hydraulic Breaker Hammer Lines” (one-way or two-way auxiliary hydraulics). The SB40 requires a 1/2 inch hose diameter.
Pressure Relief: Your excavator’s relief valve should be set slightly higher than the breaker’s operating pressure (usually around 160-170 bar) to ensure maximum performance without stalling.
Mounting Bracket: While the breaker “suits” these models, you will need a specific adapter plate (ear plate) that matches the pin diameter and spacing of your specific machine.
Would you like me to find the specific pin dimensions (pin diameter and ear width) for your specific excavator model to ensure the mounting bracket fits? Inquriy us now.
