Used Excavator Volvo EC140D Main Parts Pictures

The Volvo EC140D is a 14-ton class crawler excavator designed for heavy-duty construction tasks. Here are the main parts of the Volvo EC140D excavator:

1. Engine

• The EC140D is powered by a Volvo D4D engine, a 4-cylinder turbocharged diesel engine. This engine is responsible for providing the excavator with the necessary power to operate.

2. Hydraulic System

• The hydraulic system includes the main hydraulic pump, hydraulic cylinders, and valve block. It powers all of the excavator's movements, including boom lift, arm extension, and bucket operations.
• The hydraulic oil reservoir stores the fluid that feeds the hydraulic system.

3. Undercarriage

• Track Frame: The base structure of the undercarriage, providing the stability for the machine.
• Tracks: Made from durable steel, these allow the excavator to move across different terrains.
• Rollers: Support the track system and help distribute the weight.
• Idler and Sprocket: Help in guiding the tracks.

4. Upper Structure

• Cab: The operator’s compartment, which contains controls, a display panel, and safety features.
• Swing Bearing: Allows the upper structure (the cab, boom, and other components) to rotate 360°.
• Counterweight: Balances the excavator, preventing it from tipping over during heavy lifting or digging operations.

5. Boom and Arm

• Boom: The large, vertical arm of the excavator, which provides reach and height.
• Arm (Stick): The component attached to the boom that provides the forward reach for the bucket.
• Bucket: The attachment used for digging, lifting, and loading material.

6. Attachment System

• This is the system that allows the excavator to connect various tools such as buckets, hammers, grapples, or augers. The attachments can be swapped out depending on the task.

7. Cooling System

• Includes radiator, coolant pump, and fans, which keep the engine and hydraulic system at optimal operating temperatures.

8. Electrical System

• Alternator: Charges the battery.
• Battery: Powers the electrical components of the excavator.
• Wiring and Fuse Box: Manages electrical distribution across the system.

9. Transmission and Drive System

• This system includes the final drive motors and planetary gear system that transmit power from the engine to the tracks.

10. Swing System

• Swing Motor: Powers the rotational movement of the upper structure.
• Swing Reducer: Reduces the speed from the motor and provides torque for the swing.

11. Fuel System

• Fuel Tank: Stores the fuel for the engine.
• Fuel Filters: Clean the fuel before it enters the engine.

12. Steering System

• Pilot Valves: Control the steering, enabling the operator to maneuver the excavator.
• Hydraulic Steering Cylinders: Assist in the steering mechanism, controlling the movement of the tracks.
