• Turbocharged: The engine features a turbocharger for improved performance and fuel efficiency, providing higher power output for heavy-duty applications.
• Cooling System: The engine is equipped with a high-efficiency radiator and oil cooler to maintain optimal operating temperatures during extended hours of operation.
• Fuel System: The common rail fuel injection system optimizes fuel delivery, reducing emissions and enhancing fuel efficiency.
• Fuel Tank: The fuel tank has a large capacity, allowing for extended work periods without frequent refueling.

2. Hydraulic System

• Main Hydraulic Pump: The SY95C uses a high-performance variable displacement piston pump, providing smooth and efficient hydraulic power for all excavator operations.
• Hydraulic Cylinders: The excavator is equipped with powerful hydraulic cylinders that control the boom, arm (stick), and bucket, offering precise control over digging, lifting, and handling tasks.
• Hydraulic Control Valve: The hydraulic control valve distributes hydraulic fluid to various components of the machine, ensuring smooth operation and optimal performance.
• Pilot Control System: The pilot-controlled hydraulic system provides smooth and responsive control with minimal effort, improving the operator's comfort and efficiency.
• Hydraulic Oil Cooler: The hydraulic oil cooler ensures that the hydraulic fluid stays within the ideal temperature range, maintaining optimal hydraulic performance.

3. Undercarriage

• Track Frame: The track frame is reinforced and designed to provide the excavator with stability and support, especially when working on uneven or challenging terrain.
• Tracks: The SY95C features steel tracks, designed for durability and providing high traction on soft, muddy, or uneven ground.
• Track Rollers: Track rollers help distribute the weight of the machine evenly, reducing wear on the tracks and ensuring smooth movement.
• Idlers: The idlers at the front of the track assembly maintain proper track tension and guide the tracks for smooth operation.
• Sprockets: Sprockets are used to drive the tracks forward and backward, ensuring smooth and stable movement.
• Track Shoes: Track shoes provide traction for the machine, ensuring it moves efficiently over various surfaces.

4. Upper Structure

• Cab: The operator’s cab is designed for comfort and functionality, offering excellent visibility, ergonomic seating, and easy-to-use controls. It also includes air conditioning and sound insulation to enhance operator comfort.
• Swing Bearing: The swing bearing allows for 360-degree rotation of the upper structure, providing flexibility during tasks that require frequent repositioning of the machine.
• Counterweight: The counterweight is located at the rear of the machine, ensuring balance and stability during heavy lifting and digging operations.
• Engine Hood: The engine hood protects the internal engine components from debris, dust, and other external elements, while allowing for easy access to maintenance points.

5. Boom, Arm (Stick), and Bucket

• Boom: The boom is designed for strength and durability, providing the necessary reach and lifting power for a wide range of tasks.
• Arm (Stick): The arm (stick) connects the boom to the bucket and provides additional reach, allowing the machine to perform deep digging operations.
• Bucket: The bucket is the primary tool used for excavation, material handling, and digging. The bucket can be easily swapped for other attachments depending on the job.
• Quick Coupler: The quick coupler system allows the operator to quickly and easily change attachments without the need for manual tools, improving job site efficiency and reducing downtime.

6. Attachment System

• The SANY SY95C can be equipped with a variety of attachments for different tasks, such as:
  • Buckets (general-purpose, trenching, and heavy-duty)
  • Hydraulic Hammers
  • Grapples
  • Augers
• The quick coupler system allows the operator to switch attachments quickly, improving operational efficiency.

7. Cooling System

• Radiator: The radiator helps cool the engine coolant, maintaining the engine at optimal temperatures to avoid overheating.
• Oil Cooler: The oil cooler helps regulate the temperature of the hydraulic oil and engine oil, ensuring both systems operate at their ideal temperatures.
• Coolant Reservoir: The coolant reservoir helps maintain the required level of coolant in the engine, ensuring optimal cooling during operation.

8. Electrical System

• Alternator: The alternator provides power to recharge the battery and supply electricity to the machine's electrical components, including lights and monitoring systems.
• Battery: The battery stores energy for starting the engine and powering various electrical components.
• Fuse Box and Wiring Harness: These components distribute electrical power to the machine’s various systems, including hydraulic pumps, sensors, and other critical components.
• Machine Monitoring System: The SY95C is equipped with a machine monitoring system that provides real-time diagnostics, tracking key performance metrics such as fuel usage, engine load, and hydraulic pressure. It also helps detect potential issues before they lead to equipment failure.

9. Transmission and Drive System

• Hydrostatic Drive: The hydrostatic drive system provides smooth and responsive control of the machine’s speed and direction, making it easier to navigate tight spaces and challenging terrains.
• Final Drive Motors: The final drive motors provide the power needed to move the tracks, allowing the excavator to travel efficiently across the work site.
• Planetary Gear System: The planetary gear system ensures optimal torque and speed control, delivering efficient movement during operation.
• Travel Speed Control: The travel speed is adjustable, allowing operators to select the optimal speed for either fast transport or slow, precise movements for digging tasks.

10. Swing System

• Swing Motor: The swing motor powers the upper structure rotation, providing 360-degree rotation for the boom and arm, increasing flexibility during digging and material handling.
• Swing Reducer: The swing reducer increases torque while reducing the speed of the swing motor, ensuring smooth and controlled rotation during operation.
• Swing Ring: The swing ring allows the upper structure to rotate continuously, ensuring flexibility and stability during work tasks that require frequent repositioning.

11. Fuel System

• Fuel Tank: The excavator features a large fuel tank that minimizes downtime and allows for longer work periods between refueling.
• Fuel Filters: The fuel filters clean the fuel before it enters the engine, protecting the engine from contaminants and extending its lifespan.
• Fuel Filler Neck: The fuel filler neck makes refueling easier and more secure, ensuring that the excavator is always ready for operation.
