• Track Rollers: Track rollers ensure even distribution of weight across the tracks, improving track longevity and ensuring a smooth and stable operation.
• Idlers: The idlers at the front of the track assembly help maintain proper track tension and guide the tracks during operation.
• Sprockets: Sprockets drive the tracks, providing efficient propulsion and ensuring the machine moves smoothly across various surfaces.
• Track Shoes: The track shoes offer improved traction and support, helping the excavator move efficiently across different types of ground.

4. Upper Structure

• Cab: The operator’s cab is designed for maximum comfort, visibility, and safety. It includes air conditioning, ergonomic seating, adjustable armrests, and user-friendly controls for long periods of operation.
• Swing Bearing: The swing bearing enables the upper structure to rotate 360 degrees, giving the operator flexibility to work without needing to reposition the entire machine.
• Counterweight: The counterweight at the rear of the machine provides stability during lifting and digging tasks, ensuring the excavator remains balanced when working with heavy loads.
• Engine Hood: The engine hood is designed to protect the engine, hydraulic components, and other critical systems while allowing easy access for routine maintenance and servicing.

5. Boom, Arm (Stick), and Bucket

• Boom: The boom is engineered for heavy lifting and digging tasks, providing both strength and reach to perform a wide range of operations.
• Arm (Stick): The arm (stick) extends the reach of the boom and provides the necessary flexibility for deep digging and precise material handling.
• Bucket: The bucket is the primary tool used for excavation, material handling, and digging. It can be easily swapped for other attachments depending on the work task.
• Quick Coupler: The quick coupler system allows operators to quickly change attachments such as buckets, grapples, or hammers, without needing tools, reducing downtime and improving operational efficiency.

6. Attachment System

• The SANY SY235C is compatible with a range of attachments for diverse applications, including:
  • Buckets (general-purpose, heavy-duty, and trenching)
  • Hydraulic Hammers
  • Grapples
  • Augers
  • Thumbs for material handling
• The quick coupler system enables fast attachment changes, improving versatility and productivity on the job site.

7. Cooling System

• Radiator: The radiator keeps the engine coolant temperature at optimal levels, ensuring reliable performance under heavy loads.
• Oil Cooler: The oil cooler helps maintain the ideal temperature for both hydraulic and engine oils, enhancing operational efficiency.
• Coolant Reservoir: The coolant reservoir stores extra coolant to maintain proper levels in the cooling system, preventing overheating.

8. Electrical System

• Alternator: The alternator powers the electrical components, including the lights, sensors, and monitoring system, while also charging the machine’s battery.
• Battery: The battery provides power for starting the engine and running electrical components such as lights, sensors, and the monitoring system.
• Fuse Box and Wiring Harness: The fuse box and wiring harness help manage and distribute electrical power to various components, ensuring the efficient operation of the electrical system.
• Machine Monitoring System: The monitoring system tracks vital performance metrics such as engine load, fuel consumption, and hydraulic pressure, and provides real-time diagnostics to help identify issues early.

9. Transmission and Drive System

• Hydrostatic Drive: The hydrostatic drive system provides smooth and responsive control of the machine’s movement, especially in tight spaces or uneven terrain.
• Final Drive Motors: The final drive motors transfer engine power to the tracks, enabling the excavator to travel efficiently.
• Planetary Gear System: The planetary gear system ensures the proper torque and speed control, providing smooth operation while traveling or working.
• Travel Speed Control: The travel speed can be adjusted depending on the task at hand, whether for fast travel or slow, controlled digging.

10. Swing System

• Swing Motor: The swing motor drives the continuous rotation of the upper structure, providing 360-degree rotation of the boom and arm for increased flexibility and maneuverability.
• Swing Reducer: The swing reducer helps manage torque and speed from the swing motor, ensuring smooth and efficient rotation.
• Swing Ring: The swing ring enables smooth rotation of the upper structure, allowing for continuous movement without the need to reposition the machine.
