320 GC  Hydraulic Excavator

320 GC Hydraulic Excavator

RELIABLE. COMFORTABLE. PRODUCTIVE.

More Comfort ‚Äď More Performance ‚Äď More Versatility

  • Up To 20% Less Fuel Consumption

    A precise combination of lower engine speed and a large hydraulic pump delivers top performance while burning less fuel.

  • Improved Reliability and Efficiency

    An advanced electro-hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.

  • Up To 25% Lower Maintenance Costs

    With extended and more synchronized maintenance intervals, you get more done at a lower cost compared to the previous model.

  • Up to 21% Less CO2 Emissions

    The 320 GC emits up to 21% less CO2 than the previous 320F ECO.

Net Power - ISO 9249 (DIN) 148 hp (metric)
Note (1) Net power advertised is the power available at the flywheel when the engine is equipped with fan, air intake system, exhaust system, and alternator with engine speed at 2,000 rpm. Advertised power is tested per the specified standard in effect at the time of manufacture.
Note (2) ¬ĻCat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or ‚ÄúCaterpillar Machine Fluids Recommendations‚ÄĚ (SEBU6250) for details. *Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer). **Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
