Excavators are versatile machines commonly used in construction, mining, and demolition projects. They can be equipped with various attachments to perform specific tasks efficiently.

One of the most powerful and commonly used attachments is the hammer, which is designed to break through tough materials like concrete, rock, and asphalt.

 

But what exactly is the name of the hammer on an excavator? The correct term for this attachment is a hydraulic breaker or hydraulic hammer.

This tool uses hydraulic power to deliver strong, repetitive blows to break down hard surfaces.

In this article, we will explore the different aspects of the hydraulic breaker, its functions, benefits, and how it enhances the performance of an excavator.

What Is The Name Of The Hammer On An Excavator?

What is a Hydraulic Breaker?

A hydraulic breaker, also known as a hydraulic hammer, is an excavator attachment designed to break through hard surfaces with powerful force. It operates by using pressurized hydraulic fluid to drive a piston, which then delivers a forceful impact on the target surface.

 

Hydraulic breakers are widely used in construction, demolition, and quarrying due to their ability to efficiently break concrete, asphalt, and rock formations.

How Does a Hydraulic Breaker Work?

A hydraulic breaker is powered by the hydraulic system of an excavator. It consists of several key components, including:

1. Hydraulic Cylinder – Provides the force needed to move the piston.
2. Piston – Moves up and down, striking the tool to create impact.
3. Tool (Chisel or Moil Point) – Transfers the impact force to the material being broken.
4. Accumulator – Stores hydraulic energy to ensure consistent power delivery.
5. Control Valve – Regulates the hydraulic flow for optimal performance.

When the excavator’s hydraulic system activates the breaker, pressurized oil moves the piston, which then strikes the tool at high speed, producing a powerful impact that breaks the surface.

Benefits of Using a Hydraulic Breaker

1. Efficiency – Speeds up the demolition process compared to manual methods.
2. Versatility – Can be used on different surfaces, including concrete, asphalt, and rock.
3. Cost-Effective – Reduces labor costs by completing tasks faster.
4. Minimal Vibration – Modern breakers are designed to minimize vibrations, reducing operator fatigue.
5. Durability – Built with high-strength materials to withstand heavy-duty work environments.

Applications of Hydraulic Breakers

Hydraulic breakers are commonly used in:

• Construction – Breaking concrete slabs, foundations, and walls.
• Demolition – Removing old structures and pavement.
• Mining and Quarrying – Extracting minerals and breaking large rocks.
• Roadwork – Removing old asphalt and preparing surfaces for new construction.

Choosing the Right Hydraulic Breaker

Selecting an appropriate hydraulic breaker for an excavator is crucial for maximizing efficiency and minimizing wear on the machine. Consider the following factors when making a choice:

1. Excavator Size – Hydraulic breakers are designed to work within a specific range of hydraulic flow and pressure. Choosing a breaker that matches your excavator’s hydraulic capacity ensures optimal performance and prevents damage to the equipment.

2. Material Hardness – The type of material being broken determines the appropriate tool attachment:

   • Chisel – Ideal for precision breaking and controlled demolition.
   • Blunt Tool – Best for breaking softer materials or when surface penetration is not required.
   • Moil Point – Suitable for general-purpose breaking, particularly for reinforced concrete or frozen ground.

3. Frequency and Impact Energy – Hydraulic breakers vary in impact energy and blow frequency. Higher impact energy is necessary for breaking dense materials like reinforced concrete, while faster blow rates are effective for thinner layers of asphalt or soft rock.

4. Durability – Breakers with wear-resistant materials, reinforced housings, and advanced shock absorption systems tend to last longer. Features such as automatic lubrication systems and replaceable wear parts can further enhance the longevity of the breaker.

5. Noise and Vibration Control – If working in urban or residential areas, consider breakers with noise-reducing enclosures and vibration-dampening systems to minimize environmental impact and operator fatigue.

6. Maintenance and Serviceability – Choose a hydraulic breaker with easy access to key components for routine maintenance. Models with fewer moving parts and robust sealing systems reduce downtime and extend service life.

By carefully evaluating these factors, contractors can select a hydraulic breaker that enhances productivity, minimizes operating costs, and ensures reliable performance in demanding conditions

Maintenance Tips for Hydraulic Breakers

Proper maintenance is essential for extending the life of a hydraulic breaker. Follow these maintenance tips:

• Regularly inspect and lubricate moving parts.
• Check hydraulic hoses for leaks or damage.
• Ensure correct hydraulic pressure settings.
• Replace worn-out tools promptly.
• Store the breaker in a dry and secure place when not in use.

Hammer On An Excavator FAQs

1. What is another name for a hydraulic breaker?

Hydraulic breakers are also commonly referred to as hydraulic hammers or rock breakers.

2. What is the difference between a hydraulic breaker and a jackhammer?

A hydraulic breaker is an excavator attachment powered by hydraulic fluid, whereas a jackhammer is a handheld pneumatic tool used for smaller-scale demolition.

3. Can I use a hydraulic breaker on any excavator?

Not all hydraulic breakers are compatible with every excavator. Ensure that the breaker matches your excavator’s hydraulic capacity and specifications.

4. How do I know when to replace the tool on a hydraulic breaker?

Replace the tool when it becomes worn down, deformed, or ineffective in breaking materials efficiently.

5. Are hydraulic breakers dangerous to operate?

While hydraulic breakers are powerful tools, they can be operated safely by following proper usage guidelines, wearing protective gear, and ensuring proper machine maintenance.

6. How much does a hydraulic breaker cost?

The cost of a hydraulic breaker varies depending on size, brand, and features. Prices typically range from $5,000 to $50,000.

7. How long does a hydraulic breaker last?

With proper maintenance, a hydraulic breaker can last between 5 to 10 years, depending on usage frequency and work conditions.

Conclusion

The hammer attachment on an excavator is officially known as a hydraulic breaker or hydraulic hammer. This powerful tool is essential for breaking hard materials in construction, demolition, and mining projects.

The hydraulic breaker is a valuable addition to any excavator with its efficiency, durability, and versatility.

 

Choosing the right breaker, performing regular maintenance, and following safety guidelines can help maximize its performance and longevity.
