Used Excavator Kobelco SK60 Main Parts Pictures

The Kobelco SK60 is a hydraulic crawler excavator known for its reliable performance, fuel efficiency, and versatility in construction, demolition, and other heavy-duty applications. It is equipped with various advanced technologies and durable components to ensure optimal operation and productivity on job sites. Below are the main parts and components of the Kobelco SK60 excavator:

1. Engine

• Engine Type: The Kobelco SK60 typically uses a Komatsu SAA4D95LE-5 or similar engine, a 4-cylinder, water-cooled diesel engine.
• Rated Power: Approximately 50.4 kW (67.5 hp) at 2,000 rpm.
• Turbocharged: The engine is turbocharged to provide extra power for demanding tasks, improving overall performance and efficiency.
• Fuel System: It uses an advanced fuel injection system for better combustion efficiency and reduced emissions.
• Cooling System: Includes an engine radiator, oil cooler, and intercooler to maintain optimal engine temperatures during operation.

2. Hydraulic System

• The hydraulic system of the Kobelco SK60 is designed for high efficiency and power.
• Main Hydraulic Pump: Equipped with a variable displacement piston pump, providing high flow and pressure for smooth operation of boom, arm, and bucket movements.
• Hydraulic Cylinders: The hydraulic cylinders control the boom, arm (stick), and bucket movements. These components enable precise, powerful control for digging, lifting, and other tasks.
• Hydraulic Control Valve: Directs hydraulic fluid to various components of the machine, allowing for smooth and efficient operation of all hydraulic functions.
• Pilot Control System: The system uses pilot-operated hydraulics, providing lighter, more precise control over the machine’s movements, reducing operator fatigue.
• Hydraulic Oil Cooler: Cools the hydraulic fluid, ensuring that the system does not overheat during heavy-duty operations.

3. Undercarriage

• Track Frame: The undercarriage consists of a strong track frame that provides stability and helps distribute the weight of the machine evenly for enhanced traction and durability.
• Tracks: The Kobelco SK60 uses steel tracks designed for durability and optimal performance in rough terrain, soft ground, or even rocky surfaces.
• Track Rollers: These rollers help distribute the machine’s weight evenly across the tracks and ensure smooth movement.
• Idlers: The idlers are located at the front of the track assembly and help maintain proper tension in the tracks.
• Sprockets: Sprockets engage with the tracks, driving the excavator forward and backward.
• Track Shoes: The track shoes are the pads that come into direct contact with the ground, providing traction and stability for the excavator during operation.

4. Upper Structure

• Cab: The operator’s cab is designed for maximum comfort, safety, and visibility. It features ergonomic controls, adjustable seating, and air conditioning for operator comfort during long working hours.
• Swing Bearing: The swing bearing allows the upper structure to rotate 360 degrees, enabling the boom and arm to move freely for greater flexibility during operations.
• Counterweight: Positioned at the rear of the excavator, the counterweight ensures stability, especially during lifting operations and when working in confined spaces.
• Engine Hood: Protects the engine and the cooling system, while also allowing for easy access to components for maintenance and inspections.

5. Boom, Arm (Stick), and Bucket

• Boom: The boom is a strong, extendable arm that provides vertical reach for a variety of digging and lifting tasks.
• Arm (Stick): The arm, or stick, is the part that connects the boom to the bucket and allows the excavator to extend its reach for deeper digging.
• Bucket: The bucket is the primary tool used for digging, loading, and material handling. It can be replaced with different bucket types depending on the job (e.g., general-purpose, heavy-duty, or trenching buckets).
• Quick Coupler: A quick coupler allows the operator to rapidly change attachments, reducing downtime and improving worksite productivity.

6. Attachment System

• The Kobelco SK60 is designed to work with a variety of attachments, making it versatile and adaptable to different types of work. Common attachments include:
  • Buckets (general-purpose, heavy-duty, trenching)
  • Hydraulic Hammers
  • Grapples
  • Augers
  • Rippers
• Quick Coupler: The quick coupler system allows for easy and quick attachment changes, helping operators work efficiently across various tasks.

7. Cooling System

• Radiator: Keeps the engine coolant at a proper temperature, preventing overheating and ensuring efficient engine performance.
• Oil Cooler: Helps to prevent the hydraulic system and engine oil from overheating, ensuring smoother operation and longer service life.
• Coolant Reservoir: A separate coolant reservoir ensures there is a constant supply of coolant for the engine’s cooling system during operation.

8. Electrical System

• Alternator: Supplies electrical power to charge the battery and operate electrical components.
• Battery: Stores electrical energy for starting the engine and powering the machine’s electrical systems.
• Fuse Box and Wiring Harness: The fuse box and wiring harness manage and distribute power to the excavator’s electrical components and sensors.
• Machine Monitoring System: The monitoring system displays critical machine parameters (engine temperature, fuel level, hydraulic pressures, etc.) and offers diagnostic capabilities for easier maintenance.

9. Transmission and Drive System

• Hydrostatic Drive: The Kobelco SK60 is equipped with a hydrostatic drive system that offers precise control over the machine’s speed and direction with minimal effort.
• Final Drive Motors: These motors deliver the necessary power to drive the tracks forward or backward, allowing the excavator to move efficiently on various terrains.
• Planetary Gear System: This system reduces the speed of the drive motors while increasing torque, enabling the excavator to handle tough jobs more effectively.
• Travel Speed Control: The operator can control the travel speed to optimize performance in different work conditions.

10. Swing System

• Swing Motor: Powers the rotation of the upper structure, allowing the cab, boom, and arm to rotate 360 degrees.
• Swing Reducer: Reduces the speed of the swing motor while increasing torque, allowing smooth, controlled rotation of the upper structure.
• Swing Ring: The swing ring is the bearing system that allows continuous rotation of the upper structure, enabling the operator to adjust the boom and arm position as needed.

11. Fuel System

• Fuel Tank: The fuel tank stores the diesel required to power the engine.
• Fuel Filters: Fuel filters clean the diesel before it enters the engine, ensuring that contaminants do not affect engine performance.
• Fuel Filler Neck: Located on the side of the machine, this is where fuel is added to the tank.

12. Steering and Travel System

• Pilot-Controlled Joystick: The joystick provides the operator with precise control over the machine’s boom, arm, bucket, swing, and travel functions.
• Hydraulic Steering: The hydraulic steering system allows for easy and responsive maneuvering of the excavator, even in confined spaces.
• Travel Motors: Drive the tracks, enabling the machine to move forward or backward with ease.
• Travel Speed Control: Allows the operator to adjust the speed of travel, depending on the job requirements and ground conditions.
