Used Road Roller Dynapac CA30D Main Parts Pictures

The Dynapac CA30D is a single-drum vibratory road roller commonly used for soil compaction. It is robust and efficient, making it a popular choice in construction and road-building projects. Below are its main parts:

1. Engine

• Type: Diesel engine (commonly a Cummins or similar brand).
• Function: Powers the roller's hydraulic and vibratory systems.
• Cooling System: Includes radiator, fan, and coolant to maintain engine temperature.

2. Drum Assembly

• Drum: The large steel cylinder that provides compaction.
  • Vibratory Mechanism: Located inside the drum to generate vibrations for enhanced compaction.
• Scrapers: Keep the drum surface clean by removing debris and soil.

3. Hydraulic System

• Hydraulic Pump: Powers the drum vibration, propulsion, and steering.
• Hydraulic Motor: Drives the drum and wheels.
• Hydraulic Oil Tank: Stores hydraulic fluid for the system.

4. Chassis and Frame

• Main Frame: Provides structural support for all components.
• Articulated Joint: Allows the front drum and rear frame to pivot independently for better maneuverability.

5. Operator’s Cabin

• Controls: Levers, switches, and pedals for steering, propulsion, and vibration control.
• Display Panel: Monitors engine, hydraulic system, and vibration settings.
• Seating: Adjustable and often includes suspension for operator comfort.
• Visibility: Open or enclosed cab design with clear sightlines to the drum and surroundings.

6. Rear Wheels

• Drive Wheels: Provide traction and mobility.
• Tires: Heavy-duty tires designed for stability and operation on various terrains.

7. Steering System

• Hydrostatic Steering: Uses hydraulic power for precise and effortless maneuvering.

8. Vibratory System

• Eccentric Weights: Inside the drum to create vibration for soil compaction.
• Vibration Control: Adjusts the amplitude and frequency of vibrations based on the compaction requirements.

9. Fuel System

• Fuel Tank: Stores diesel fuel for the engine.
• Fuel Filters: Remove impurities to protect the engine.

10. Electrical System

• Battery: Powers the starter motor and electrical components.
• Lighting: Work lights for night or low-visibility operation.
• Wiring Harness: Connects the electrical components.

11. Braking System

• Service Brake: For normal operation and stopping.
• Parking Brake: Ensures the roller remains stationary when parked.

12. Water Spray System (Optional)

• Water Tank: Stores water for spraying on the drum.
• Spray Nozzles: Prevent soil from sticking to the drum during operation.
