Product & applications
About the concrete buster
A twin-cylinder hydraulic jaw attachment for breaking concrete during demolition and cutting suitable reinforcing steel with removable blades.
Features & benefits
Cylinder protective covers
Covers protect the cylinders during contact with demolition material.
Alloy-steel frame and arms
Special alloy steel forms the body frame and working arms.
Removable rebar blades
The cutting blades can be removed for servicing or replacement.
Typical applications
- Concrete structure demolitionBreak concrete sections that fit the selected jaw opening and crushing geometry.
- Reinforcement processingUse the blade section to cut suitable reinforcing steel during concrete demolition.
- Confined demolition workPosition the jaws around accessible concrete sections where the machine and attachment can operate within their limits.

Excavator class and weight
Compare each DS model’s 10–36 t carrier range and 1100–2800 kg attachment weight with the excavator lifting chart.
Pin or coupler connection
Check mounting pin diameters, centres, clear width and any quick-coupler geometry.
Hydraulic supply
The table states 32 MPa pressure and model-specific 100–360 L/min flow ranges. Check the selected model rather than the whole series envelope.
Concrete dimensions and jaw positioning
Compare material dimensions with maximum jaw opening, blade length and the available working space.
Product questions
Concrete buster questions
Is this a hydraulic breaker?
No. Hydraulic cylinders close the jaws around concrete; a hydraulic breaker uses a striking tool.
How does it differ from a multi-purpose processor?
This series is a concrete-breaking jaw tool. An interchangeable-jaw processor changes working jaw arrangements for different tasks.
Does jaw opening equal permitted material thickness?
No. Opening is a geometry measurement. Material strength, reinforcement and the working section also affect selection.
Which hydraulic figures apply to my machine?
Use the flow range in the selected model column and its 32 MPa oil pressure; check excavator supply, controls and return requirements.

Rotating pulverizer
A rotating hydraulic pulverizer for positioning the jaws around concrete sections, crushing concrete and separating reinforcing steel. Rotation allows the operator to adjust the jaw angle to the work.
Demolition & Cutting Tools
Multi-purpose demolition processor
A rotating, twin-cylinder demolition attachment with interchangeable jaw arrangements for concrete breaking, separation and cutting suitable metal sections.
Demolition & Cutting Tools
Concrete cutter
A hydraulic demolition cutter for breaking reinforced concrete sections and cutting exposed reinforcing steel. Compare jaw dimensions and crushing forces at the tip and centre for the material and carrier.
