Used CAT320D Crawler Excavator

The CAT320D excavator offers powerful power, comfortable operation, and easy maintenance, as follows: Excellent Power and Performance Efficient and Reliable Engine: The Caterpillar C6.4 engine, featuring ACERT Technology, delivers optimal engine performance while meeting global low-emission regulations, delivering powerful power and excellent fuel efficiency. The radially sealed air filter features a double-layer filter element for enhanced filtration efficiency and effective engine protection. Advanced Hydraulic System: Hydraulic system pressure has been increased to 35,000 kPa, increasing arm and bucket force by 5% and tractive effort to 206 kN, enabling it to handle demanding excavation operations. The hydraulic cross-sensing system maximizes engine power, increasing implement and pivot speeds for enhanced productivity. Boom and stick regeneration circuits conserve energy during boom-down and stick-retract operations, improving efficiency and reducing cycle time and pressure loss. Flexible Work Modes: Use Power Mode to match the excavator to the job, or use Smart Mode to automatically match engine and hydraulic power to digging conditions for optimal results. Comfortable and Convenient Operation Optimal Cab Design: The radiator is located on the side of the cab superstructure, allowing outside air to enter the engine compartment from the operator side and hot air and engine noise to exhaust from the opposite side. This reduces engine compartment heat and noise transmitted to the operator, improving comfort. Intelligent Operation: The operator-oriented user interface uses simple icons for quick machine setup and easy access to information. This reduces calibration time and improves work tool combination setup efficiency. Cat Payload provides on-the-go weighing, helping operators accurately achieve target loads and avoid overloading, underloading, or misloading materials. Low Maintenance Costs Easy Maintenance: Most common service points are accessible from ground level. For example, the pump and filter are located behind the right-hand service door, while the radiator, oil cooler, and other components are easily accessible through the left rear service door. The double-layer air filter features a clogging warning, facilitating timely filter replacement. Durable Components: The boom and digging arm utilize a large box-section structure with internal baffles that absorb twisting forces. Manipulator-welded, they offer high strength. The X-shaped box-section body resists twisting and distributes stress. The track rollers are sealed and dust-proof, and the track chain is grease-lubricated, extending undercarriage life and reducing operating costs.
