Cat Medium Excavators 320GC
Product Feature
High Performance with Lower Fuel Consumption
Use up to 20% less fuel than the 320F excavators.
Match the excavator to the job using power modes including new Smart Mode that automatically matches engine and hydraulic power to 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.
Your joystick commands adjust pump flow based on valve priority putting hydraulic pressure and flow where it needs to go giving you improved fast light-to-medium load cycle times.
The electronically controlled, turbocharged engine meets U.S. EPA Tier 4 Final and EU Stage IV emissions standards using a transparent aftertreatment system that requires no operator input or downtime.
Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
Don't let the temperature stop you from working. The excavator has a standard high-ambient temperature capability of 125 º F (52º C) and cold start capability of 0º F (-18º C). An optional -25º F (-32º C) cold start package is available .
Work up to 9,480 feet (3000 meters) above sea level without de-rating.
Track your performance through standard Product Link that provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes and other machine data on demand through VisionLink ® online interface.
