Used Excavator SANY SY35U Main Parts Pictures

The Sany SY35U is a compact, mini hydraulic excavator designed for small to medium construction and excavation tasks. It offers excellent maneuverability, high productivity, and low fuel consumption. The following are the main parts of the Sany SY35U Excavator:

1. Engine

• Engine Type: The Sany SY35U is powered by a Yanmar 4TNV88 4-cylinder, water-cooled, turbocharged diesel engine.
• Rated Power: Approximately 24.4 kW (32.7 hp) at 2,400 rpm.
• Turbocharged: The engine is equipped with a turbocharger, boosting its efficiency and power output, especially for demanding operations.
• Cooling System: Includes a radiator and oil cooler to maintain optimal engine temperatures, preventing overheating during extended operations.
• Fuel System: The fuel system uses an advanced common rail fuel injection technology, which improves fuel efficiency, reduces emissions, and enhances engine performance.
• Fuel Tank: A large-capacity fuel tank ensures long operational hours before needing to refuel.

2. Hydraulic System

• Main Hydraulic Pump: The SY35U is equipped with a high-flow, variable displacement piston pump, capable of delivering high pressure and flow for quick and efficient hydraulic operation.
• Hydraulic Cylinders: These cylinders control the movement of the boom, arm (stick), and bucket. They provide powerful and precise operation, ideal for digging, lifting, and material handling.
• Hydraulic Control Valve: The control valve directs hydraulic fluid to various components, enabling smooth and coordinated movements of the boom, arm, and bucket.
• Pilot Control System: The pilot-operated hydraulic system reduces the effort required to operate the controls, offering smooth, responsive, and precise control of the machine.
• Hydraulic Oil Cooler: The cooler ensures that the hydraulic oil remains at optimal temperatures, preventing overheating and ensuring reliable hydraulic operation.

3. Undercarriage

• Track Frame: The undercarriage includes a heavy-duty track frame that provides stability and durability, allowing the machine to operate on rough and uneven terrain.
• Tracks: The SY35U uses steel tracks designed to provide excellent traction and durability, especially in soft soil and muddy conditions.
• Track Rollers: These rollers distribute the weight of the excavator evenly across the tracks, reducing wear and tear while ensuring smoother operation.
• Idlers: Positioned at the front of the tracks, the idlers maintain proper track tension and help guide the tracks along the undercarriage.
• Sprockets: The sprockets drive the tracks, providing efficient movement in forward and reverse directions.
• Track Shoes: The track shoes are large, durable pads that provide traction to prevent slipping and ensure a firm grip on different surfaces.

4. Upper Structure

• Cab: The operator’s cab is designed for comfort, visibility, and safety. It features a spacious design, ergonomic controls, and air conditioning, offering a comfortable environment for long hours of operation.
• Swing Bearing: The swing bearing allows the upper structure to rotate 360 degrees, enabling flexible operation for digging and material handling.
• Counterweight: A counterweight is located at the rear to provide balance during heavy lifting and digging operations.
• Engine Hood: The engine hood protects the engine and other vital components from dust and debris while providing easy access for maintenance and service.

5. Boom, Arm (Stick), and Bucket

• Boom: The boom is a long, robust arm that provides vertical reach for the machine, enabling efficient lifting and digging tasks.
• Arm (Stick): The arm or stick connects the boom to the bucket and provides extra reach for deeper digging and handling of materials.
• Bucket: The bucket is the primary tool for digging, loading, and material handling. Different bucket attachments can be used for various tasks (e.g., general-purpose, trenching).
• Quick Coupler: The quick coupler system allows for fast and easy attachment changes without requiring manual tools, increasing the machine's versatility and reducing downtime.

6. Attachment System

• The Sany SY35U can be equipped with a variety of attachments, including:
  • Buckets (general-purpose, trenching, or heavy-duty)
  • Hydraulic Hammers
  • Grapples
  • Rippers
  • Augers
• The quick coupler system enables the operator to easily switch between different attachments, making the machine adaptable for different tasks.

7. Cooling System

• Radiator: The radiator cools the engine coolant and prevents the engine from overheating during prolonged work periods.
• Oil Cooler: The hydraulic oil cooler ensures that the hydraulic fluid remains at the correct temperature, preventing overheating and maintaining system efficiency.
• Coolant Reservoir: The coolant reservoir holds the coolant, ensuring the engine has a constant supply to maintain the ideal operating temperature.

8. Electrical System

• Alternator: The alternator provides the electrical power needed to charge the battery and operate electrical components like lights and control systems.
• Battery: Stores electrical energy for the excavator’s starting system and operates electrical systems.
• Fuse Box and Wiring Harness: The fuse box and wiring harness ensure the proper distribution of electrical power to the excavator’s various systems, such as the hydraulic pumps, lights, and sensors.
• Machine Monitoring System: The SY35U is equipped with a machine monitoring system that allows operators to track performance, including fuel consumption, hydraulic pressure, and engine temperature. This helps in predictive maintenance and performance optimization.
