Product & applications
About the side-type hydraulic breaker
An open-frame hydraulic breaker with a side-mounted bracket for breaking rock and concrete. Check the mounting geometry and hydraulic requirements for your excavator.
Features & benefits
Piston and cylinder assembly
The extended piston and heat-treated cylinder deliver hydraulic hammer action to the working tool.
Guided and sealed mechanism
The seal arrangement guides the moving components and keeps dust away from the lubricated mechanism.
Typical applications
- Wall and structure demolitionPosition the chisel against suitable concrete sections where side-bracket access is useful.
- Rock breakingBreak rock using a working tool selected for the material and operating method.
- Bridge and confined-access workUse the selected bracket geometry to reach accessible breaking points within the excavator working range.
Match the breaker to your excavator.
Compare machine weight, hydraulic flow and pressure together. Hammer weight differs between side, top and box configurations.
Pressure unit: kgf/cm². This table retains its original numerical values. Pressure is not shown in bar.

Product questions
Side-type hydraulic breaker questions
Is excavator weight enough to select a breaker?
No. Compare oil flow, pressure, return requirements, mounting and attachment mass with the selected model.
What should I compare when choosing a side-type breaker?
Compare the bracket or housing dimensions, mounting connection and available working clearance for the intended breaking task.
How is the working tool selected?
Choose the specified point or chisel for the material and work. Rock breaking and concrete demolition can require different working tools.
Does it need a dedicated hydraulic check?
Yes. Confirm the hammer circuit, pressure, flow and return arrangement against the installation instructions. Do not infer suitability from pin fit alone.
