Excavator Rock Breaker
An excavator rock breaker comes in when a bucket cannot make a clean start in rock, concrete, or hard ground. It breaks the material first, so the machine can clear, dig, or continue with bucket work afterward.

Product Overview
Breaking Hard Material Before Bucket Work
A rock breaker, often called a hydraulic hammer attachment, sits between rough ground and the bucket work that follows. It breaks rock, concrete, and hard layers into smaller sections before the excavator clears, loads, or digs the material away.
Key Product Features
Breaker quality is not only about impact force. Hydraulic match, tool seating, and bracket fit decide how the unit is supplied.
Hydraulic Match
Oil flow, working pressure, and auxiliary line setup are matched to the carrier before confirmation.
Tool Seating
The chisel, tool bush, and lower contact area are reviewed so the tool sits straight under load.
Mounting Bracket Fit
Bracket size, pin position, and hose clearance are checked around the excavator arm and carrier setup.
Breaker Uses
Common Uses of Excavator Rock Breakers
Most breaker jobs start before any real removal work happens. The breaker opens the hard layer first; after that, a bucket or another attachment can move the broken material out of the way.
Rock Breaking
Breaks rock and hard layers into pieces that can be cleared, loaded, or dug out.
Concrete Breaking
Works on concrete sections, slabs, and hard surfaces before the broken material is loaded or removed.
Hard Ground Work
For compacted ground or hard material that slows down normal bucket digging.
Demolition Follow-up
Useful for light demolition follow-up where concrete or hard material needs breaking before clean-up.
Breaker Fit & Working Range
Breaker fit is not only about excavator size. Machine weight, hydraulic flow, working pressure, mounting setup, and the material being broken all affect breaker size, tool choice, and working range.
Machine Size
Machine model and operating weight set the first breaker size range.
Mounting Setup
Hydraulic flow, working pressure, and hose setup should be checked before the breaker is confirmed.
Work Material
Rock, concrete, hard ground, and broken demolition material can affect breaker size and tool choice.
What To Check
For a breaker fit review, clear machine details, hydraulic information, mounting dimensions, and site photos are usually sufficient to get started.
Mounting Setup
Send model, operating weight, machine class, and any current attachment setup details.
Hydraulic Details
Oil flow, working pressure, hose layout, and available auxiliary lines should be checked where possible.
Pin & Bracket Details
Pin diameter, pin centres, arm width, and bracket photos help confirm the mounting.
Work Requirement
Describe the material being broken, such as rock, concrete, hard ground, or light demolition follow-up.
