Used CAT320D marine excavator

The CAT320D marine excavator offers powerful power, high operating efficiency, comfortable operation, and low maintenance costs. The advantages are as follows: Superior Power and Performance Powerful: Equipped with a Caterpillar C6.4 ACERT engine rated at 103 kW, it provides ample power to meet the demands of a variety of complex working environments. High Digging Force: The bucket digging force reaches 140.1 kN, and the arm digging force reaches 106.4 kN. This powerful digging force makes it easier and more efficient to dig through hard soil and rock. Wide Operating Range: With a maximum digging radius of 9,850 mm, a maximum digging depth of 6,710 mm, and a maximum digging height of 9,840 mm, it delivers excellent performance in a variety of working environments. Advanced Hydraulic System: The main pump utilizes a Caterpillar axial piston pump + pilot pump, with a maximum flow rate of 404 L/min, ensuring stable hydraulic pressure and flow output. The rationally designed control circuit ensures more precise and smooth operation during delicate work. Flexible Work Modes: Use Power Mode to match the excavator to the job, or Intelligent Mode to automatically adjust engine and hydraulic power to digging conditions for optimal results. Comfortable and Convenient Operation Rational Cab Design: The standard ROPS cab complies with ISO 12117-2:2008 requirements and features smaller cab pillars, large windows, and a flat hood design, providing excellent visibility for the operator. User-Friendly Interface: The latest operator-oriented user interface uses simple, easy-to-use icons for easy navigation and operation, as well as quick machine setup and information access. Rich Assistance Features: Cat Payload provides on-the-go weighing, helping operators achieve target weights every time and avoid overloading, underloading, or misloading materials. The single-handle operation design makes operation easier. Low Maintenance Costs Long Maintenance Intervals: Compared to previous models, maintenance intervals are extended and more synchronized, with hydraulic oil filter changes up to 3,000 hours between changes. Using genuine Cat oil and filters and regular S∙O∙S monitoring can extend current service intervals to 1,000 hours. Easy Maintenance: All routine maintenance tasks are accessible at ground level. For example, the ground-level engine oil dipstick allows for quick and safe checking of the engine oil level, and the reversible electric cooling fan facilitates easy cleaning of the radiator, oil cooler, and condenser. High Durability Rugged Structure: The heavy-duty bucket design and large, box-section boom and stick constructed of high-tensile-strength steel, along with internal baffles to absorb torsional stress and reinforced undercarriage protection, are engineered to withstand harsh operating environments. Reliable Component Quality: Sealed lubrication on track rollers, carrier rollers, and other components effectively reduces internal bushing wear and extends service life. Thick braiding protects the colored and numbered wires, and non-abrasive connectors secure the wiring harness to prevent failure.
