• Hydraulic Cylinders: The excavator features high-performance hydraulic cylinders that control the boom, arm (stick), and bucket, allowing for precise movement in all types of applications.
• Hydraulic Control Valve: The hydraulic control valve is responsible for distributing hydraulic fluid to different components of the machine, ensuring smooth and responsive operations.
• Pilot Control System: The pilot-operated hydraulic system reduces operator effort, offering smoother and more precise control of the machine.
• Hydraulic Oil Cooler: The hydraulic system is equipped with an oil cooler to maintain optimal hydraulic fluid temperatures, improving overall system efficiency.

3. Undercarriage

• Track Frame: The track frame is designed to provide stability and durability, allowing the machine to operate efficiently on uneven or challenging terrain.
• Tracks: The SY135C uses steel tracks for superior traction and durability, especially when operating on soft or muddy ground.
• Track Rollers: The track rollers help distribute the weight of the excavator evenly, reducing wear on the tracks and improving stability.
• Idlers: The idlers at the front of the track assembly maintain track tension and ensure smooth movement during operation.
• Sprockets: Sprockets drive the tracks, providing motion and stability during travel and work tasks.
• Track Shoes: The track shoes offer enhanced grip and traction, helping the excavator move over various surfaces.

4. Upper Structure

• Cab: The operator’s cab is designed for comfort and safety, featuring excellent visibility, ergonomic seating, and easy access to controls. It includes air conditioning, sound insulation, and adjustable seats to improve the operator's working conditions.
• Swing Bearing: The swing bearing allows for 360-degree continuous rotation of the upper structure, making it easier for the operator to perform tasks without repositioning the entire machine.
• Counterweight: The counterweight at the rear of the machine ensures stability during heavy lifting and digging operations.
• Engine Hood: The engine hood provides protection for critical components like the engine, radiator, and hydraulic systems while allowing easy access for maintenance.

5. Boom, Arm (Stick), and Bucket

• Boom: The boom is designed for heavy lifting and digging, providing strong performance and long reach for various applications.
• Arm (Stick): The arm (stick) provides additional reach and flexibility when digging, allowing for deep and precise digging.
• Bucket: The bucket is the primary tool for excavation, material handling, and digging. It can be easily swapped with different types of attachments depending on the task at hand.
• Quick Coupler: The quick coupler system enables the operator to quickly change attachments without using manual tools, reducing downtime and improving operational efficiency.

6. Attachment System

• The SANY SY135C is compatible with various attachments for a range of applications, including:
  • Buckets (general-purpose, trenching, and heavy-duty)
  • Hydraulic Hammers
  • Grapples
  • Augers
• The quick coupler system allows for fast and easy attachment swaps, improving versatility and reducing downtime.

7. Cooling System

• Radiator: The radiator cools the engine coolant, maintaining optimal engine temperature to prevent overheating during extended periods of operation.
• Oil Cooler: The oil cooler helps regulate the temperature of the hydraulic oil and engine oil, ensuring the efficiency of both systems.
• Coolant Reservoir: The coolant reservoir stores additional coolant, helping maintain the necessary levels to prevent overheating.

8. Electrical System

• Alternator: The alternator generates power to charge the battery and supply electricity to the electrical systems, including lights, sensors, and other vital components.
• Battery: The battery provides electrical power for starting the engine and powering electrical systems.
• Fuse Box and Wiring Harness: These components manage and distribute electrical power to various systems on the excavator, including hydraulic systems, lights, and sensors.
• Machine Monitoring System: The monitoring system tracks real-time machine performance, displaying diagnostics such as fuel usage, engine load, and hydraulic pressures. It helps operators detect issues early and improve machine longevity.

9. Transmission and Drive System

• Hydrostatic Drive: The hydrostatic drive system provides smooth control over the machine's speed and direction, making it ideal for precise operations in confined spaces or uneven ground.
• Final Drive Motors: The final drive motors transmit power from the engine to the tracks, enabling the excavator to move efficiently.
• Planetary Gear System: The planetary gear system ensures the proper torque and speed control to allow smooth movement during operation.
• Travel Speed Control: The travel speed is adjustable, allowing the operator to select a slower speed for digging or a faster speed for traveling between work sites.

10. Swing System

• Swing Motor: The swing motor powers the continuous rotation of the upper structure, allowing for 360-degree rotation of the boom and arm.
• Swing Reducer: The swing reducer increases torque and reduces the speed of the swing motor, providing smooth and controlled rotation.
• Swing Ring: The swing ring allows for the continuous rotation of the upper structure, enabling versatile operation without repositioning the machine.

11. Fuel System

• Fuel Tank: The large-capacity fuel tank minimizes downtime, enabling the excavator to operate for longer periods without the need for refueling.
• Fuel Filters: The fuel filters remove impurities from the fuel before it enters the engine, preventing damage and extending the engine's life.
• Fuel Filler Neck: The fuel filler neck is designed for easy and secure refueling.

12. Steering and Travel System

• Pilot-Controlled Joystick: The joystick provides control over all major machine functions, including boom, arm, bucket, swing, and travel. It reduces operator fatigue by offering intuitive, responsive control.
