Used Road Roller SHANTUI SR12 Main Parts Pictures

The SHANTUI Road Roller SR12 is a powerful and efficient compactor designed for road construction and soil compaction tasks. Below is a detailed breakdown of its main parts:

1. Engine

• Type: Diesel engine, typically a Weichai or Cummins model.
• Power Output: Approximately 100–125 HP (75–93 kW).
• Air Filtration System: Multi-stage air filter to ensure clean air intake for optimal engine performance.
• Cooling System: Radiator and cooling fan for maintaining appropriate engine temperatures.
• Fuel System:
  • Fuel tank
  • Fuel injectors
  • Fuel pump
  • Fuel filters
• Exhaust System: Muffler and exhaust pipe to reduce noise and emissions.

2. Drum and Compaction System

• Front Drum:
  • Type: Vibratory or static drum.
  • Width: Typically 2.1–2.3 meters.
  • Vibration Mechanism: Eccentric weights inside the drum generate vibrations for compaction.
  • Drum Scrapers: Prevent material buildup on the drum.
• Rear Tires: Dual rubber tires provide traction and contribute to compaction.
• Sprinkler System: Sprays water to prevent asphalt or soil from sticking to the drum.

3. Hydraulic System

• Main Hydraulic Pump: Powers vibration, propulsion, and steering systems.
• Hydraulic Motor: Drives the drum’s vibration system.
• Hydraulic Reservoir: Stores hydraulic fluid for operations.
• Control Valves: Direct hydraulic fluid to specific components.
• Hydraulic Lines and Hoses: Transport hydraulic oil under pressure.

4. Chassis and Frame

• Main Frame: High-strength steel construction for durability and structural integrity.
• Articulated Joint: Provides flexibility between the front and rear sections for better maneuverability.
• Anti-Vibration Mounts: Reduce vibration transfer to the operator's cabin.

5. Operator’s Cabin

• ROPS/FOPS: Roll-Over and Falling Object Protective Structures ensure operator safety.
• Seat: Adjustable, ergonomic seat for operator comfort during long operations.
• Control Console:
  • Joystick controls for driving and vibration settings.
  • Instrument panel for monitoring engine status, vibration frequency, and other key indicators.
• Visibility: Large glass windows for clear visibility of the work area.
• Climate Control: Air conditioning and heating for operator comfort.

6. Drive System

• Travel Motors: Hydraulic motors that power the drum and rear tires for movement.
• Transmission: Hydrostatic transmission for smooth and efficient operation.
• Axles: Rear axle supports traction and load-bearing.

7. Steering System

• Type: Hydraulic articulated steering.
• Steering Pump: Powers the hydraulic system for steering.
• Steering Cylinder: Adjusts the articulation of the front and rear sections.

8. Electrical System

• Battery: Powers the engine starter and electrical components.
• Alternator: Charges the battery and supplies electricity during operation.
• Lighting System:
  • Headlights and taillights for nighttime operations.
  • Work lights for enhanced visibility in low-light conditions.
• Wiring Harness: Connects electrical components across the machine.
• Warning Systems: Alerts for engine faults, low fuel, or hydraulic issues.

9. Vibration Control System

• Amplitude Control: Adjusts the depth of compaction based on material type.
• Frequency Adjustment: Allows changes to vibration intensity for specific compaction needs.
• Eccentric Weights: Generate vibration within the drum for effective compaction.

10. Safety Features

• Emergency Stop Button: Quickly shuts down the machine in emergencies.
• Backup Alarm: Alerts nearby workers when the roller is reversing.
• Seat Belt: Secures the operator during operation.
• Handrails and Steps: Ensure safe access to the cabin.

11. Water Spray System

• Water Tank: Stores water for drum sprinkling.
• Spray Nozzles: Distribute water evenly onto the drum surface.
• Water Pump: Delivers water from the tank to the spray nozzles.

12. Tires and Traction System

• Rear Tires: Provide traction and additional compaction force.
• Tire Tread Design: Ensures grip on loose or uneven surfaces.

13. Cooling System

• Radiator: Keeps the engine and hydraulic systems at optimal temperature.
• Cooling Fan: Ensures sufficient airflow through the radiator.
• Oil Cooler: Prevents overheating of hydraulic and engine oils.

14. Counterweight

• Rear Counterweight: Enhances machine stability and compaction force by balancing the load.
