Hard rock and reinforced concrete slow down most excavation projects. Ordinary digging buckets cannot break tough geological layers efficiently. Contractors lose time and money on delayed site progress. A hydraulic hammer for excavator solves these breaking challenges with powerful impact energy. YG Machinery supplies 11 models for carriers from 4 to 80 tons. Share your carrier model and breaking needs for a free tailored quote.

Working Principle of Hydraulic Hammer for Excavator
How does this attachment generate such powerful breaking force? The excavator hydraulic system supplies pressurized oil to the breaker cylinder. Inside, a heavy piston moves rapidly up and down. An accumulator stores hydraulic energy to boost each impact stroke. When the piston strikes the chisel, kinetic energy transfers directly into rock. The reversing valve switches oil flow direction automatically after each stroke. This cycle repeats hundreds of times every minute.
Nitrogen gas in the back head cushions the piston return. It also adds extra energy to each downward blow. The chisel tip shape determines how energy concentrates on the target. Moil points deliver focused penetration. Blunt tools spread energy over a wider area for secondary breaking. This design gives the hydraulic hammer for excavator its core advantage.
Top 5 Benefits of Hydraulic Hammer for Excavator
Why do contractors rely on this attachment for tough breaking jobs?
- Fast Breaking Speed: Impact energy reaches 9000 Joules on heavy models. Breaking efficiency is 2 to 5 times higher than ordinary manual tools.
- Precise Control: Operators adjust impact force and frequency easily. It avoids damage to surrounding structures during renovation work.
- Low Operating Cost: No separate engine or fuel system needed. It runs entirely on the excavator’s existing hydraulic power source.
- Durable Components: Hardened steel chisels and wear-resistant seals extend service life. Oil return channel design reduces seal pressure buildup.
- Versatile Application: Works for rock, concrete, asphalt, and demolition projects. It handles both above-ground and underwater breaking tasks.
Our company also supplies other demolition tools for integrated site solutions. You can find a pile breaker, diamond wire saw, concrete wall saw, and rock splitter in our product range. We support one-stop procurement for all construction demolition needs.
How to Select the Right Hydraulic Hammer for Excavator?
Choosing the correct match improves both performance and machine lifespan. Consider three key factors before placing an order.
First, match the breaker weight to your excavator class. An oversized breaker strains the carrier’s hydraulic system. An undersized one wastes time and lowers productivity. Use the model table above as a starting reference.
Second, verify working pressure and oil flow compatibility. Each model requires a specific hydraulic flow range. Check your excavator pump output against the breaker specification. Mismatched flow causes overheating and early wear.
Third, pick the right chisel type for your material. A point works best for general rock breaking. A blunt tool suits secondary concrete breaking. Wedge chisel handles asphalt and light reinforced concrete.

Why Choose YG as Your Hydraulic Breaker Manufacturer?
YG Machinery has manufactured construction equipment since 2005. We focus on hydraulic attachments and demolition tool quality. Every breaker passes strict factory pressure and impact testing before shipment.
We offer three body types for different working conditions:
- Side Type: Compact and low-profile for tight working spaces.
- Top Type: High power output for heavy-duty rock breaking.
- Box Type: Noise-reduced housing ideal for urban construction sites.
All models use premium sealing systems and heat-treated steel components. We support custom chisel designs and mounting bracket fabrication. As an experienced hydraulic breaker manufacturer, we export to over 60 countries worldwide. Our team provides fast spare parts supply and remote technical guidance.
Hydraulic Breaker vs Rock Splitter: Which Should You Buy?
Both tools break hard rock, but they work in very different ways. Understanding the difference helps you choose the right tool.
A hydraulic breaker delivers repeated impact blows to fracture rock quickly. It works fast on massive rock masses and concrete structures. Noise and vibration levels are higher during operation. Best for open-pit mining, large demolition, and road construction.
A rock splitter inserts a steel wedge into a pre-drilled hole. Hydraulic pressure expands the wedge to split rock silently. It produces almost no vibration or flying debris. Ideal for urban areas near buildings and sensitive infrastructure.
Choose a breaker when speed matters and space is open. Choose a splitter when noise and vibration must stay low. Contact our team to compare both options for your specific project.
