1. Overview
Breaker attachments—also known as hydraulic hammers—are powerful demolition tools used with full-size skid steer loaders to break concrete, asphalt, and rock. Driven by hydraulic flow, they deliver high-impact blows through a hardened chisel, making them ideal for construction, demolition, and utility excavation.
2. Applications
Concrete slab and sidewalk demolition
Asphalt road and pavement breaking
Trenching in hard or rocky soils
Rock splitting and site prep
Demolition of foundations or retaining walls
3. Compatibility
3.1 Mounting System
Mount Type

Check both flow and pressure output of your loader before selecting a breaker model.
4. Key Components
Component
Function
Hydraulic Cylinder
Drives piston via hydraulic pressure
Piston & Impact System
Transfers energy into the chisel through rapid striking motion
Chisel/Tool Bit
Hardened steel bit that contacts and breaks material
Housing/Body
Encloses internal components and reduces vibration
Mounting Frame
Connects breaker to skid steer’s quick-attach plate
Nitrogen Chamber (optional)
Boosts striking power in gas-charged breakers

7. Operating Guidelines
7.1 Setup
Mount breaker securely to skid steer’s quick-attach system
Connect hydraulic lines (check for flow direction and pressure rating)
Ensure all bolts and couplings are tight
Test fire the breaker for proper movement and pressure response
7.2 Breaking Technique
Position tool bit vertically on the target surface
Engage hydraulics and apply slight downward pressure
Let the breaker hammer repeatedly—do not pry or force movement
Break small sections at a time to avoid bit binding
Move position frequently to reduce overheating and wear
8. Safety Best Practices
Wear PPE: hard hat, hearing protection, gloves, steel-toe boots
Keep all personnel at least 15 ft from the breaker when operating
Never use the breaker as a prying or lifting device
Avoid dry firing (striking with no material underneath)
Shut off hydraulics and relieve pressure before servicing
9. Maintenance Schedule
Task
Frequency
Inspect hydraulic lines for leaks
Daily
Check chisel bit and retainer condition
Every 8 hours
Grease tool bushings and couplers
Every 4 hours
Inspect nitrogen charge (if applicable)
Weekly
Check for loose bolts and cracks
After each use
Replace worn bits or tool holders
As needed
10. Selection Tips
Match GPM and PSI to breaker spec for consistent impact energy Choose bit type based on material (moils for general, chisels for slabs) Use heavier-duty models for thick concrete or rock Look for replaceable wear parts and sealed housing for longer life Ensure compatibility with your loader’s hydraulic and mounting system
Verify attachment fits securely to your loader’s quick-attach system.
Check both flow and pressure output of your loader before selecting a breaker model.
