1. Hydraulic Breaker

Purpose: A hydraulic breaker, often referred to as a hydraulic hammer, is essential for breaking up hard surfaces such as asphalt and concrete.

Application: During road repair, a hydraulic breaker is used to demolish damaged or old road surfaces. This attachment delivers powerful blows to break up the material into smaller, manageable pieces, making it easier to remove and replace.

Benefits:

• Efficiency: Speeds up the demolition process compared to manual methods.
• Precision: Allows for targeted breaking of specific areas without affecting surrounding surfaces.
• Power: Handles tough materials with ease, essential for heavy-duty repairs.

2. Planer (Milling Attachment)

Purpose: A planer, or milling attachment, is used to remove a specific depth of material from the road surface, typically asphalt.

Application: In road repair, the planer is employed to mill down the existing asphalt to a uniform depth before applying a new layer. This ensures a smooth transition between old and new surfaces and corrects any surface irregularities.

Benefits:

• Uniformity: Provides a consistent depth of material removal, essential for a smooth final surface.
• Versatility: Can be adjusted to mill different depths depending on the repair requirements.
• Preparation: Creates an ideal surface for the new asphalt to adhere to, enhancing the quality of the repair.

3. Sweeper

Purpose: A sweeper attachment is used for cleaning debris, dust, and loose material from the road surface.

Application: After milling or breaking up the old surface, a sweeper is used to clean the area thoroughly. This step is crucial to remove any loose particles and dust that could affect the bonding of new materials or compromise the quality of the repair.

Benefits:

• Cleanliness: Ensures that the surface is free from debris, which is vital for the proper application of new materials.
• Efficiency: Speeds up the cleanup process, allowing for faster transition to the next phase of repair.
• Maintenance: Keeps the work area clean, improving safety and productivity.

The "Three Swordsmen" in Action

The combination of the hydraulic breaker, planer, and sweeper—referred to as the "three swordsmen"—provides a comprehensive solution for road repair. Each attachment plays a distinct role:

1. Hydraulic Breaker: Breaks up the damaged road surface.
2. Planer: Mills the surface to the correct depth for repair.
3. Sweeper: Cleans the surface to ensure proper bonding of new materials.
