9 Essential Benefits of Using a Digger Hydraulic Breaker for Modern Construction
A digger hydraulic breaker is one of the most powerful and widely used attachments in today’s construction and demolition industry. Whether you’re breaking concrete, crushing rocks, or clearing hard ground, a high-quality hydraulic breaker transforms a standard digger into a true demolition machine. With increased demand for faster and more precise work, contractors rely heavily on hydraulic breakers to improve productivity and reduce manual labor.
In this article, we explore how digger hydraulic breakers work, their components, benefits, applications, and how to choose the right model for your machine.
Understanding What a Digger Hydraulic Breaker Is
Basic Definition and Purpose
A digger hydraulic breaker is a hammer attachment that is powered by the hydraulic system of a digger. It can break the hardest materials, including:
Reinforced concrete
2. Granite and rock
3. Asphalt
4. Brick and stone
5. Frozen or compacted soil
How It Works on Different Digger Types
Hydraulic breakers can be fitted to:
1. Mini diggers
2. Medium-sized diggers
3. Large excavators
The breaker receives hydraulic oil flow from the digger, driving the piston to strike the chisel with tremendous force—often hundreds of times per minute.
Main Components of a Digger Hydraulic Breaker
1. Chisel / Tool
The part that directly impacts the material—available in moil, blunt, wedge, and conical shapes.
2. Piston
Creates the powerful mechanical energy needed for striking.
3. Seal Kits
Ensure hydraulic oil does not leak and maintains required pressure.
4. Valve Sleeve& Cylinder
Regulate hydraulic energy and direct force efficiently.
These components must work together perfectly to deliver high impact energy without failure.
Types of Digger Hydraulic Breakers
Side Type Breaker
A simple structure that is easy to maintain and cost-effective.
Top Type Breaker
Delivers strong vertical impact—ideal for deeper breaking tasks.
Box / Silent Type Breaker
Contains noise-reduction features, suitable for residential or urban environments.
How to Choose the Right Digger Hydraulic Breaker
Make Sure It's the Right Weight for Your Machine
The breaker must be the right weight for your machine. This will stop it from getting damaged.
How much hydraulic power do you need?
Your digger's hydraulic output (pressure and oil flow) must meet the breaker's specifications.
Application Needs
For example:
1. Urban demolition → silent type
2. Quarry mining → top type
3. Road surface removal → side type
Comparison Table: Hydraulic Breaker Options for Diggers
| Breaker Type | Advantages | Suitable Jobs | Noise Level |
|---|---|---|---|
| Side Type | Easy repair & affordable | Roadwork, general construction | Medium |
| Top Type | Highest impact power | Mining, quarry, heavy demolition | High |
| Silent / Box | Low vibration & low noise | Urban demolition | Low |
Top Applications of a Digger Hydraulic Breaker
Road Construction
Great for breaking up asphalt, curbs and road foundations.
Concrete Demolition
This is a way to get rid of slabs, beams and reinforced concrete structures quickly and easily.
Quarrying and mining
You can use this for crushing stone, extracting ore and for mining without blasting.
Maintenance Tips to Maximize Breaker Lifespan
Daily Care
1. Check oil hoses
2. Inspect bolts
3. Ensure no hydraulic leaks
4. Check chisel wear
Lubrication Practices
Apply proper chisel grease every 2 hours to reduce friction.
Storage Tips
Store upright in a dry area and relieve hydraulic pressure after use.
Most Common Spare Parts for Digger Hydraulic Breakers
1. Seal kits
2. Diaphragms
3. Damper
4. Piston
5. Chisel
6. Wear bushes (upper & lower)
7. Through bolts and side bolts
8. Rod pin and stop pin
9. Valve Sleeve components
10. Accumulator & N₂ gas charging kit
High-quality replacement parts prevent downtime and increase breaking efficiency.
Signs Your Digger Hydraulic Breaker Needs Repair
--Weak impact force
--Abnormal vibration
--Oil leaking from the breaker
--Overheating
--Inconsistent operation
