The Hitachi ZX200-3G is a medium-sized crawler excavator designed for a variety of construction, digging, lifting, and material handling tasks. It offers a balance of power, fuel efficiency, and durability. Below are the main parts of the Hitachi ZX200-3G excavator:

1. Engine

• Engine Type: The ZX200-3G is powered by a Isuzu 6HK1 turbocharged, water-cooled diesel engine.
• Rated Power: The engine provides approximately 129 kW (173 hp) at 1,800 rpm.
• Turbocharged: The engine’s turbocharger improves fuel efficiency and increases output, which is essential for demanding work environments.
• Fuel Tank: The high-capacity fuel tank allows for extended operating hours, reducing the need for frequent refueling during long working shifts.

2. Hydraulic System

• Main Hydraulic Pump: The ZX200-3G features a variable displacement piston pump, which provides precise and powerful hydraulic flow for various tasks, such as digging, lifting, and material handling.
• Hydraulic Cylinders: The hydraulic cylinders control the movement of the boom, arm (stick), and bucket, enabling smooth and powerful operation.
• Hydraulic Control Valve: The control valve distributes hydraulic fluid to different parts of the system, ensuring controlled and efficient operation of the hydraulic components.
• Pilot-Controlled Hydraulic System: The pilot-controlled hydraulic system enables the operator to perform fine, precise movements with minimal effort.
• Hydraulic Oil Cooler: The hydraulic oil cooler helps regulate the temperature of the hydraulic fluid, ensuring the system operates efficiently and prevents overheating during intensive use.

3. Undercarriage

• Track Frame: The track frame provides support and stability, particularly on uneven terrain, ensuring the machine remains balanced during operation.
• Tracks: The ZX200-3G uses steel tracks, offering excellent traction, durability, and performance on a wide range of surfaces, including mud and rough ground.
• Track Rollers: The track rollers distribute the machine’s weight evenly, reducing wear on the tracks and providing smooth movement.
• Idlers: Idlers maintain the correct tension on the tracks, preventing slippage and ensuring optimal movement.
• Sprockets: The sprockets transmit power from the engine to the tracks, enabling movement.
• Track Shoes: The track shoes provide additional traction and stability, especially on loose or slippery surfaces.

4. Upper Structure

• Cab: The operator’s cab is designed for comfort and efficiency, featuring ergonomically positioned controls, a suspension seat, air conditioning, and excellent visibility of the work area.
• Swing Bearing: The swing bearing enables the upper structure to rotate 360 degrees, offering high maneuverability for tasks requiring rotation, such as material handling and digging.
• Counterweight: The counterweight is located at the rear of the machine to ensure stability during heavy lifting and digging operations, helping to prevent tipping.
• Engine Hood: The engine hood is designed to protect the engine and critical components while allowing easy access for routine maintenance and inspections.

5. Boom, Arm (Stick), and Bucket

• Boom: The boom provides the necessary reach and digging depth for a variety of tasks.
• Arm (Stick): The arm (stick) extends the boom for additional reach, offering versatility in material handling and digging operations.
• Bucket: The bucket is used for digging, material loading, and other excavation activities. The ZX200-3G can be fitted with different types of buckets, such as general-purpose, heavy-duty, and trenching buckets.
• Quick Coupler: The quick coupler system allows operators to quickly change attachments, such as buckets, grapples, or hammers, without needing manual tools, improving productivity.

6. Attachment System

• The ZX200-3G is compatible with a wide range of attachments, including:
  • Buckets (general-purpose, heavy-duty, or trenching)
  • Hydraulic Hammers
  • Grapples
  • Augers
  • Rotating and Tilting Attachments
• The quick coupler system enables rapid attachment changes, reducing downtime between tasks and improving operational efficiency.

7. Cooling System

• Radiator: The radiator maintains the engine coolant at an optimal temperature to prevent overheating during intensive operations.
• Oil Cooler: The oil cooler regulates the temperature of both the engine and hydraulic oils, ensuring efficient and safe operation in high-stress conditions.
• Coolant Reservoir: The coolant reservoir maintains the coolant level, preventing the engine from running with insufficient cooling fluid.

8. Electrical System

• Alternator: The alternator generates electrical power to run the machine’s electrical components, including lights, sensors, and monitoring systems.
• Battery: The battery powers the electrical system and provides the necessary energy to start the engine.
• Fuse Box and Wiring Harness: The fuse box and wiring harness distribute electrical power to various systems and components, ensuring the smooth functioning of the excavator.
• Machine Monitoring System: The monitoring system provides real-time data on the health and performance of the machine, such as engine temperature, fuel efficiency, hydraulic pressures, and maintenance alerts.

9. Transmission and Drive System

• Hydrostatic Drive: The ZX200-3G uses a hydrostatic drive system, which allows smooth, precise movement and speed control for a wide range of tasks.
• Travel Motors: The travel motors transfer power from the engine to the tracks, enabling the machine to move efficiently across different surfaces.
• Planetary Gear System: The planetary gear system is used to transmit power from the engine to the tracks, ensuring reliable movement and variable speed control.
• Travel Speed Control: The travel speed is adjustable to meet the specific requirements of different job sites, whether the operator needs slower speeds for precise tasks or higher speeds for quick repositioning.

10. Swing System

• Swing Motor: The swing motor powers the 360-degree rotation of the upper structure, providing excellent maneuverability and flexibility for working in tight spaces.
• Swing Reducer: The swing reducer manages the torque and speed of the swing motor to ensure smooth and controlled rotation of the upper structure.
• Swing Ring: The swing ring supports the rotation mechanism and ensures stable and reliable movement.

11. Fuel System

• Fuel Tank: The fuel tank is designed for long operating hours and reduces the need for frequent refueling during extended shifts.
• Fuel Filters: The fuel filters prevent contaminants from entering the fuel system, ensuring that the engine receives clean fuel for optimal performance.
• Fuel Filler Neck: The fuel filler neck allows for safe and efficient refueling, reducing the risk of spills and improving operational efficiency.
