A hydraulic breaker for excavators is one of the most demanded attachments in construction, mining, demolition, and quarrying. It delivers powerful impact energy to break rocks, concrete, and hard materials efficiently. Today, contractors are not just looking for any breaker—they want the best hydraulic breaker, reliable performance, easy maintenance, and the right compatibility with their excavator. As a professional excavator attachment manufacturer, Changyu Machine provides heavy-duty and long-lasting breakers trusted by global customers.
This complete guide explains types, prices, applications, selection criteria, working principles, and everything you need to choose the best model for your project.
What Is a Hydraulic Breaker for Excavators?
A
hydraulic breaker for excavators (also known as a
hydraulic hammer) is a powerful attachment that uses hydraulic pressure to generate high-impact blows. It is widely used for breaking rocks, reinforced concrete, frozen ground, and pavement. Breakers are compatible with:
• Excavators
• Mini excavators
• Backhoe loaders
• Skid steers
• Tractors
• Mini diggers
How Hydraulic Breakers Work: Structure & Working Principle
Understanding the
hydraulic breaker working principle helps buyers select a reliable model. The breaker converts the
hydraulic oil pressure from the excavator into a high-speed impact motion. Inside the breaker:
• The hydraulic system pushes the
piston • The piston strikes the
chisel tool • High-impact energy breaks the target material
Main internal structures include:
• Cylinder
• Piston
• Valve system
• Front head & back head
• Nitrogen chamber
• Chisel or moil point
This mechanism allows the breaker to work continuously with high efficiency.
Changyu Machine designs its breakers with improved oil flow channels and enhanced pistons for stable operation.
Types of Hydraulic Breakers: Light, Medium, and Heavy-Duty
Hydraulic breakers come in three performance categories:
Light-Duty BreakersIdeal for small machines such as
mini excavators, mini diggers, and skid steers.
Applications: landscaping, small concrete removal, light demolition.
Medium-Duty BreakersFits 7–20 ton excavators.
Applications: roadwork, urban demolition, recycling.
Heavy-Duty BreakersDesigned for 20–60 ton excavators or larger.
Applications:
mining, quarrying, heavy rock breaking.
These are used when maximum impact energy is required.
The quality of a breaker depends on its internal structure. A superior breaker should include:
•
High-strength piston with wear resistance
•
Reinforced front head to absorb force
•
Durable chisel tool made from alloy steel
•
Nitrogen chamber for energy boosting
•
Stable valve system to control oil flow
•
Noise-reduction housing for urban work
•
High-precision seals to prevent oil leakage
Changyu Machine uses imported seal kits and precision CNC machining to ensure long working life, reducing downtime and maintenance cost.
How to Match a Hydraulic Breaker with Your Excavator Model
Choosing the best hydraulic breaker depends heavily on
excavator compatibility.
The breaker must match your excavator’s:
• Oil flow (L/min)
• Operating pressure
• Carrier weight
• Bucket capacity
• Linkage size
• Working environment
Use an
excavator compatibility chart or ask the manufacturer directly.
Changyu Machine supports custom matching for all excavator brands such as CAT, Komatsu, Hitachi, SANY, Doosan, Hyundai, and Volvo.
Incorrect matching can cause:
• Low impact force
• Seal damage
• Overheating
• Reduced lifespan
Impact Energy, Blow Frequency & Power—What Really Matters?
When comparing the
best hydraulic breakers, focus on these performance indicators:
Impact Energy (Joules)Higher impact energy = more rock-breaking power.
Blow Frequency (BPM)The number of blows per minute.
More BPM = faster productivity.
Working Pressure & Oil FlowThese must match the excavator’s hydraulic system.
Tool DiameterLarger diameter = stronger breaking capacity.
Durability & Steel QualityDirectly affects the maintenance cost.
Changyu Machine optimizes piston design to deliver strong
breaker hammer impact energy while keeping the internal temperature stable.
Applications of Hydraulic Breakers in Construction & Mining
Hydraulic breakers are used in almost every heavy-duty project, including:
• Rock breaking in mines
• Primary & secondary rock demolition
• Road construction
• Concrete demolition
• Tunnel construction
• Foundation excavation
• Pavement removal
• Frozen ground breaking
• Quarrying operations
Hydraulic Breaker Prices in 2025: What Affects the Cost?
The
hydraulic breaker price depends on several factors:
1. Breaker Size & CategoryMini-excavator breakers cost less; heavy-duty models cost more.
2. Steel Material & Manufacturing QualityHigh-quality materials increase durability and price.
3. Impact Energy & PerformanceHigher impact energy models cost more.
4. Brand ReputationTop manufacturers like
Changyu Machine provide stable quality with reasonable pricing.
5. Additional FeaturesSoundproof housing, auto-grease systems, reinforced tools.
Price Range (2025 Estimate): •
Mini excavator breaker: $650 – $1,200
•
Medium breaker: $1,500 – $3,500
•
Heavy-duty breaker: $4,000 – $9,000+
Hydraulic Breaker vs. Other Excavator Attachments
Compared to other rough materials processing attachments:
Hydraulic BreakerBest for rock breaking, concrete demolition, and quarry operations.
Hydraulic CrusherUsed for crushing reinforced concrete.
RipperSuitable for frozen ground but not for rock.
BucketUsed for digging, not demolition.
If the job involves hard rock or thick concrete, the
hydraulic breaker is the best and fastest solution.
Maintenance Tips to Extend Your Hydraulic Breaker Lifespan
Proper maintenance can double the lifespan of your breaker:
• Lubricate the tool before every shift
• Check oil pressure daily
• Avoid blank firing
• Inspect the chisel for wear
• Replace seals regularly
• Use the correct hydraulic oil
• Clean the housing after use
• Avoid overheating during long operations

Common Problems & How to Troubleshoot Hydraulic Breakers
Typical issues include:
Weak Impact ForceCause: low oil flow, worn piston, nitrogen leak.
Solution: refill nitrogen, check oil lines, replace worn parts.
OverheatingCause: long continuous operation, wrong oil.
Solution: allow cooling, use proper oil grade.
Oil LeakageCause: damaged seals or hose connections.
Solution: replace seal kits, tighten fittings.
Blank FiringCause: wrong working angle or tool wear.
Solution: maintain correct angle; replace tool.
