How a Hammer Transforms an Excavator: Unleashing Versatility on the Job Site


Excavators are the backbone of modern construction and earthmoving projects. When paired with specialized attachments, their potential expands dramatically. Among these attachments, the hydraulic hammer (or breaker) stands out as a game-changer. By transforming the excavator into a powerful demolition tool, the hammer brings versatility, precision, and efficiency to a range of challenging tasks. In this blog, we explore how a hammer transforms an excavator, the wide variety of applications it unlocks, and tips for maximizing its utility.


1. What is a Hydraulic Hammer?

A hydraulic hammer is a robust attachment designed to deliver intense percussive force, ideal for breaking through hard materials. It operates by converting the hydraulic energy generated by the excavator into mechanical energy, resulting in a powerful hammering motion. Hydraulic hammers come in different sizes and power levels, enabling compatibility with excavators of varying capacities.

Key components of a hydraulic hammer include:

  • Piston: Transfers energy to the tool bit.

  • Tool bit (chisel, moil, or blunt): The business end that interacts with the material.

  • Accumulator: Enhances efficiency by storing hydraulic energy.

  • Housing: Protects internal components and reduces vibrations.


2. Transforming Excavator Capabilities with a Hammer

A. Versatility in Applications

Adding a hammer to an excavator opens up a broad spectrum of applications that would otherwise require specialized machinery. These include:

  1. Demolition Work:

    • Breaking down concrete structures, walls, and foundations.

    • Pulverizing reinforced concrete for recycling.

  2. Rock Breaking:

    • Splitting large boulders in quarrying operations.

    • Preparing construction sites with rocky terrains.

  3. Trenching and Pipeline Installation:

    • Breaking through hard layers of bedrock to install pipelines or utilities.

    • Excavating narrow trenches in tough soil conditions.

  4. Mining and Quarrying:

    • Extracting minerals by breaking large rock formations.

    • Assisting in secondary rock breaking to achieve manageable sizes.

  5. Roadwork and Asphalt Removal:

    • Breaking asphalt for road repair and maintenance.

    • Demolishing old roads and driveways.

  6. Underwater Operations:

    • Demolishing submerged structures.

    • Breaking rocks in underwater construction or dredging projects.

B. Enhanced Efficiency

Hydraulic hammers significantly reduce the time and labor required for tasks like manual rock-breaking or concrete removal. The speed and force of a hammer-equipped excavator outperform traditional methods, allowing contractors to meet deadlines faster and more cost-effectively.

C. Increased Safety

Using a hammer attachment improves job site safety by minimizing the need for manual labor in hazardous conditions. Workers remain in the safety of the excavator cab, reducing exposure to falling debris, vibrations, or flying particles.


3. Key Features of Hydraulic Hammers

Modern hydraulic hammers are equipped with features that enhance their performance and durability. Some of these include:

  • Auto-Lubrication Systems: Prolongs tool life by ensuring consistent lubrication during operation.

  • Anti-Blank Firing Mechanisms: Prevents damage to the hammer by disabling operation when the tool bit is not in contact with a surface.

  • Variable Blow Energy: Adjusts the impact force to suit different materials.

  • Noise Reduction: Quieter operation through advanced housing designs, making them suitable for urban environments.


4. Factors to Consider When Using a Hydraulic Hammer

A. Compatibility

The excavator's size, hydraulic flow rate, and pressure should match the specifications of the hammer. Oversized or undersized hammers can cause inefficiencies or damage to the equipment.

B. Tool Bit Selection

Different tool bits are designed for specific applications:

  • Chisel: For breaking through concrete.

  • Moil Point: For general-purpose rock breaking.

  • Blunt: For compacting and breaking softer materials.

C. Hydraulic System Maintenance

The hydraulic system of the excavator must be in excellent condition to handle the demands of the hammer. Regularly inspect hoses, seals, and hydraulic fluid levels.

D. Operating Techniques

  • Avoid continuous hammering in one spot to prevent overheating.

  • Use the hammer at the correct angle to avoid stress on the tool bit and excavator arm.

  • Engage the hammer only when the tool bit is in firm contact with the material.


5. Advantages of Using a Hammer with an Excavator

  1. Cost Savings:By adding a hammer to your excavator, you eliminate the need to invest in dedicated demolition equipment, reducing overall costs.

  2. Compact and Mobile Solution:Excavators equipped with hammers can operate in confined spaces, making them ideal for urban or residential projects where larger machinery cannot fit.

  3. Eco-Friendly Demolition:Modern hydraulic hammers are energy-efficient and produce minimal noise and dust, aligning with environmental regulations.

  4. Customizable Options:A wide range of hammers and tool bits ensures that you can tailor the excavator for specific tasks.


6. Common Challenges and Solutions

While hydraulic hammers are powerful tools, they come with challenges:

Challenge 1: Tool Bit Wear and Tear

Solution: Regular inspection and timely replacement of worn tool bits ensure consistent performance. Using high-quality OEM parts, like those from Vikfin, extends the lifespan of the hammer.

Challenge 2: Hydraulic Overheating

Solution: Implement proper operating practices, including taking breaks during prolonged hammering and maintaining optimal hydraulic fluid levels.

Challenge 3: Vibration Damage to the Excavator

Solution: Modern hammers come with vibration dampening features. Properly securing the attachment and regular maintenance of the excavator arm are also critical.


7. Maintaining and Extending the Life of a Hydraulic Hammer

A. Regular Inspections

Inspect the hammer and excavator for cracks, loose bolts, or hydraulic leaks before and after each use.

B. Proper Storage

Store the hammer in a clean, dry environment to prevent rust and contamination.

C. Lubrication

Ensure the hammer receives proper lubrication at recommended intervals to reduce friction and wear.

D. Training Operators

Well-trained operators know how to use the hammer efficiently, reducing the risk of damage from improper techniques.


8. Why Consider Used Hydraulic Hammers?

High-quality used hydraulic hammers from trusted suppliers like Vikfin offer excellent value for money. These pre-owned attachments undergo rigorous testing and refurbishment to ensure reliability. By opting for a used hammer, you can expand your excavator's capabilities without straining your budget.
