• Rated Power: Approximately 36.2 kW (48.5 hp) at 2,400 rpm.
• Turbocharged: The turbocharger enhances engine performance and efficiency, providing higher power output while maintaining lower fuel consumption.
• Cooling System: The engine is equipped with a high-performance radiator and oil cooler system, maintaining optimal engine temperatures even in demanding conditions.
• Fuel System: The common rail fuel injection system ensures efficient combustion, reducing emissions and improving fuel efficiency.
• Fuel Tank: The large-capacity fuel tank provides long operational hours, minimizing downtime for refueling.

2. Hydraulic System

• Main Hydraulic Pump: The SY55C features a variable displacement piston pump, offering high flow rates and pressure for efficient hydraulic operation, ensuring smooth and quick control of the excavator’s functions.
• Hydraulic Cylinders: The hydraulic cylinders control the movement of the boom, arm (stick), and bucket, providing precise and powerful digging, lifting, and handling capabilities.
• Hydraulic Control Valve: The control valve manages the flow of hydraulic fluid to the various parts of the machine, ensuring smooth coordination of movements during operations.
• Pilot Control System: The pilot-controlled hydraulic system reduces the effort needed for operation, offering smooth, accurate control and a more comfortable user experience.
• Hydraulic Oil Cooler: The hydraulic oil cooler keeps the fluid at the ideal temperature, preventing overheating and ensuring consistent hydraulic performance.

3. Undercarriage

• Track Frame: The heavy-duty track frame provides structural support to the undercarriage and ensures the excavator remains stable, even on rough or uneven ground.
• Tracks: The SY55C is equipped with steel tracks for durability, providing high traction on soft ground or uneven surfaces.
• Track Rollers: These distribute the machine’s weight evenly, reducing wear on the tracks and ensuring smoother movement.
• Idlers: Idlers are mounted at the front of the track assembly, ensuring proper track tension and contributing to the smooth operation of the tracks.
• Sprockets: The sprockets provide the necessary engagement to drive the tracks forward or backward, offering stability during movement.
• Track Shoes: The track shoes are designed to increase traction and help prevent slipping, improving stability and mobility.

4. Upper Structure

• Cab: The operator’s cab is designed for comfort and efficiency, with ergonomic controls, spacious layout, and excellent visibility. It also includes air conditioning for a comfortable working environment.
• Swing Bearing: The swing bearing allows for continuous rotation of the upper structure, providing excellent flexibility in operations like material handling and digging.
• Counterweight: The counterweight is strategically placed at the rear of the machine to maintain stability during lifting and digging operations.
• Engine Hood: The engine hood is designed to protect the engine from dirt and debris while providing easy access for maintenance and inspections.

5. Boom, Arm (Stick), and Bucket

• Boom: The boom provides the necessary height and reach for the machine. It is designed for strength and durability, suitable for various digging and lifting tasks.
• Arm (Stick): The arm or stick connects the boom to the bucket, offering additional reach for more efficient digging.
• Bucket: The bucket is the primary attachment used for digging and material handling. It can be customized with various types depending on the job (e.g., general-purpose, trenching, or heavy-duty).
• Quick Coupler: The quick coupler allows for easy and quick attachment changes without the need for manual tools, improving operational efficiency and reducing downtime.

6. Attachment System
