What Size Hydraulic Hammer Is Right for My Excavator?
Choosing the correct hydraulic hammer size keeps your excavator and operator safe, efficient, and productive. Be sure to match the hammer attachment to your machine’s weight, hydraulic flow, and job application for the best results.
When you’re breaking rock, concrete, or hard ground, a successful job depends on the hammer you use. Selecting the right hydraulic hammer ensures peak performance, protects your machine, and helps you get the job done faster.
At Rocxbreaker, we build high-performance hydraulic hammers built for strength, power, and durability. Whether you’re trenching for utilities, processing recycled materials, doing foundation work, or tackling demolition projects, choosing the correct breaker size can make all the difference.
Why Does Hammer Attachment Size Matter?
Your excavator and hammer must work together for optimum performance:
- A hammer that’s sized too small won’t deliver enough impact energy and may be damaged due to incorrect hydraulic pressure and flow.
- A hammer that’s sized too large can shock load or compromise your excavator boom, hydraulic system, or main frame, and therefore cause severe damage.
The right match gives you:
- Higher productivity
- Reduced wear and tear
- Longer equipment life
What Should You Consider Before Choosing?
When selecting a hydraulic hammer, review these key factors:
- Carrier weight class: Match the hammer to your excavator’s operating weight.
- Hydraulic flow and pressure: Ensure your excavator’s hydraulic system supports the hammer’s requirements.
- Application type: Different materials need different impact energy levels.
- Tool diameter: Larger tools are better suited for handling heavier jobs and harder materials.
Selecting the right hydraulic hammer helps you work faster, safer, and more efficiently. It also protects your investment by reducing wear on your host machine.
