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)

¹Cat engines are compatible with diesel fuel blended with the following lower-carbon intensity fuels** up to: 100% 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 “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details. *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.

The excavator uses up to 20% less fuel than the 320D2 GC in similar applications.
Match the excavator to the job using power modes; let Smart mode automatically match engine and hydraulic power to your digging conditions.
The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.
Valve priority puts hydraulic pressure and flow where you command it to go for fast light- to medium-load cycle times.
Meets Brazil MAR-1 emission standards, equivalent to U.S. EPA Tier 3 and EU Stage IIIA.
Add auxiliary hydraulics to do more work with a range of Cat attachments.
VisionLink® provides actionable data insights for all assets - regardless of fleet size or equipment manufacturer. Review equipment data from your desktop or mobile device to maximize uptime and optimize assets.
Don't let the temperature stop you from working. The excavator has a standard high ambient temperature capability of 52º C (125º F) and cold start capability of -32º C (-25º F).

Expect up to 20% less maintenance cost than the 320D2 GC (savings calculated over 12,000 machine hours).
Do all daily maintenance at ground level.
