3. Undercarriage

• Track Frame: The track frame ensures the stability and durability of the machine, especially in tight or uneven working conditions.
• Tracks: The ZX65U uses steel tracks, which provide excellent traction and durability, ensuring smooth operation on rough terrain and in confined spaces.
• Track Rollers: The track rollers help distribute the weight of the machine evenly across the tracks, reducing wear and improving machine stability.
• Idlers: Idlers are used to maintain proper track tension, ensuring the tracks run smoothly and evenly.
• Sprockets: Sprockets are essential components that drive the tracks and contribute to the smooth movement of the machine.
• Track Shoes: The track shoes help improve traction and mobility on various surfaces, ensuring the excavator remains stable during operation.

4. Upper Structure

• Cab: The operator’s cab is designed for comfort and visibility. It features ergonomic controls, air conditioning, and a high-quality seat, providing a comfortable working environment even for long shifts.
• Swing Bearing: The swing bearing enables the upper structure to rotate 360 degrees, allowing the operator to maneuver the machine and complete tasks more efficiently.
• Counterweight: The counterweight is located at the rear of the machine to provide balance, especially when lifting heavy loads or performing excavation tasks.
• Engine Hood: The engine hood protects the engine and other key components while allowing for easy access during maintenance.

5. Boom, Arm (Stick), and Bucket

• Boom: The boom is the primary lifting arm that enables the excavator to reach and perform excavation tasks.
• Arm (Stick): The arm (stick) extends the boom, allowing deeper digging and more versatile material handling.
• Bucket: The bucket is used for digging and material handling. The ZX65U can be fitted with different types of buckets, such as general-purpose, heavy-duty, or trenching buckets, depending on the job.
• Quick Coupler: The quick coupler system allows for fast and easy attachment changes, improving the machine’s versatility and reducing downtime.

6. Attachment System

• The ZX65U is compatible with a variety of attachments for different applications, including:
  • Buckets (for general digging, heavy-duty work, or trenching)
  • Hydraulic Hammers
  • Grapples
  • Augers
  • Rotating and Tilting Attachments
• The quick coupler system makes it easy to switch between different attachments, increasing the flexibility and productivity of the excavator.

7. Cooling System

• Radiator: The radiator ensures that the engine coolant is at an optimal temperature, preventing the engine from overheating during extended operation.
• Oil Cooler: The oil cooler regulates the temperature of both the engine oil and hydraulic oil, which helps maintain efficient engine and hydraulic system performance.
• Coolant Reservoir: The coolant reservoir stores extra coolant to maintain proper levels in the cooling system.

8. Electrical System

• Alternator: The alternator provides power for the electrical components of the machine, including the lights, sensors, and monitoring system, and charges the battery.
• Battery: The battery is used for starting the engine and powering electrical components when the engine is off.
• Fuse Box and Wiring Harness: The fuse box and wiring harness distribute electrical power to different components, ensuring proper functioning of the electrical systems.
• Machine Monitoring System: The monitoring system provides real-time diagnostics and alerts, displaying key performance metrics like engine temperature, fuel consumption, hydraulic pressures, and overall machine health.

9. Transmission and Drive System

• Hydrostatic Drive: The hydrostatic drive system provides smooth, variable-speed travel. It allows precise control over the machine’s movement and makes the ZX65U highly maneuverable, especially in tight spaces.
• Travel Motors: The travel motors transfer the engine’s power to the tracks, enabling the excavator to move over various surfaces, including rough and uneven terrain.
• Planetary Gear System: The planetary gear system adjusts the torque and speed of the machine, enabling efficient travel and operation.
• Travel Speed Control: The travel speed can be adjusted, allowing operators to control the pace depending on the task at hand.
