320 GC Hydraulic Excavator

High Performance with Lower Fuel Consumption

  • Use up to 20% less fuel than the 320D2 GC excavator.
  • Match the excavator to the job using power modes; let Smart mode automatically match engine and hydraulic power to working 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 Tier 3/Stage IIIA equivalent emission standards.
  • Auxiliary hydraulic options give you the versatility to use a range of Cat attachments.
  • Don’t let the temperature stop you from working. The excavator has a standard high-ambient temperature capability of (52º C) 125º F and -32º C (-25º F) cold start package.
  • Work up to 9,480 feet (3000 m) above sea level without de-rating.

Work in Comfort in the All-New Cab

  • Sit in new, wide seats that adjust for operators of all sizes.
  • Enjoy wide spacing between consoles for a more comfortable environment.
  • Control the excavator comfortably with easy-to-reach controls all located in front of you.
  • Standard automatic climate control keeps you at the right temperature throughout your shift.
  • Improved viscous mounts reduce cab vibration by up to 50% over previous excavator models.
  • Stow your gear with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles. A cup holder, document holder, bottle holder, and coat hook are also provided.
  • The standard radio has USB ports and Bluetooth® technology enabled to connect your device and make hands-free calls.

Built for Long Life

  • Protect hydraulic components in cold weather. The auto warm-up feature speeds hydraulic oil warming in cold temperatures.
  • The fuel system is protected from dirty fuel by three levels of filtration.
  • Bottom guarding protects engine and hydraulic components from damage while swinging and traveling.
  • The hydraulic tank uses a new oval shape to improve stress resistance.
  • The strong X-structure lower frame carries the loads from the machine upper structure to the track.
  • Travel motor hydraulic lines are routed inside of the frame to protect from damage.
  • The sloped track frame design prevents mud and debris from accumulating and damaging tracks.
  • The grease lubricated tracks have grease sealed between the pin and bushing to prevent debris from entering and reducing life.
  • The track rollers are sealed to prevent dirt and debris causing wear of internal components.
  • A bolt-on track guiding guard helps maintain track alignment while traveling or working on slopes.

Simple to Operate

  • Start the engine with a push button; use a Bluetooth key fob, smartphone app, or the unique Operator ID function.
  • Program each joystick button, including response and pattern, using Operator ID; it will also will remember climate control fan and radio settings.
  • Use the high-resolution 203 mm (8″) touchscreen monitor with jog dial control to make machine adjustments with ease.
  • The operator’s manual is always at your fingertips in the touchscreen monitor.

Maintenance

  • Expect up to 15% less maintenance cost than the 320D2 GC due to extended and synchronized service intervals and smaller fluid quantities. (Savings calculated over 12,000 machine hours.)
  • Do all daily maintenance at ground level.
  • Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
  • Check engine oil level quickly and safely with the new ground-level engine oil dipstick; fill and check engine oil on top of the machine with a conveniently located second dipstick.
  • Change all fuel filters at a synchronized 500 hours.
  • Expect the new air intake filter with pre-cleaner to last up to 1,000 hours — a 100% increase over the previous filter.
  • The new hydraulic oil filter provides improved filtration performance, anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3,000 hour replacement interval
     - 50% longer than previous filter designs.
  • The new high-efficiency electric cooling fans only run when needed and reverse to keep cores free from debris.
  • S·O·S℠ports are on ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.

Safety

  • Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the pushbutton starting feature.
  • See clearly through large windows with narrow cab pillars.
  • An available electric refueling pump shuts off automatically to help you avoid overfilling and spilling.
  • The new right-hand steps provide easy, safe, and quick access to the upper service platform; the steps use antiskid plates anchored with recessed bolts to prevent slipping.
  • The standard roll-over protective structure (ROPS) cab meets ISO 12117-2 2008 requirements.
  • The handrails comply with ISO2867 requirements.
  • The lower frame meets ISO15818 lifting and tie-down requirements.
