Change model

Overview

The Cat® 320 GC excavator balances productivity with easy-to-use technology features, a new comfortable cab, reduced fuel consumption by up to 20%, and longer maintenance intervals reducing maintenance costs by up to 15% to bring you a durable, low-cost-per-hour excavator for light- to medium-duty applications.

Up To 20% More Fuel Efficient

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 20% Lower Maintenance Costs

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

PERFORMANCE WITH LESS FUEL
- The excavator uses up to 20 percent 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 U.S. EPA Tier 3/EU Stage IIIA/China Nonroad Stage III/Brazil MAR-1 equivalent emission standards.
- Add auxiliary hydraulics to do more work with a range of Cat attachments.
- Product Link™ comes standard so you can remotely monitor machine health, location, hours, and fuel consumption on demand through the VisionLink® online interface.

LOWER MAINTENANCE COSTS
- Expect up to 15 percent less maintenance cost than the 320E (savings calculated over 12,000 machine hours).
- Do all daily maintenance at ground level.
- Check engine oil level quickly and safely with the new ground-levelengine oil dipstick; fill and check engine oil on top of the machine with a conveniently located second dipstick.
- Track your excavator’s filter life and maintenance intervals via thein-cab monitor.
- No required maintenance on the Cat Clean Emissions Module.
- Change all fuel filters at a synchronized 500 hours.
- Expect the new air intake filter with precleaner to last up to 1,000 hours – a 100 percent 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 percent 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 simplify maintenance and allow for quick, easy extraction of samples for fluid analysis.
Read More
RELIABILITY YOU CAN COUNT ON
- Work up to 3000 m (9,840 ft) above sea level without de-rating.
- Standard high-ambient temperature capability is 52º C (125º F) with cold start capability at –32º C (–25º F).
- Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.
- Three levels of fuel filtration protect the engine from dirty diesel fuel.
- Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
- The center track guiding guard helps keep the excavator track aligned when traveling and working on slopes.
- The sloped track frame prevents mud and debris accumulation, helping reduce risk of track damage.
Read More
SAFELY HOME EVERY DAY
- Access 100 percent of daily maintenance points from ground level – no need for you to climb on top of the excavator.
- Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the pushbutton starting feature.
- The standard ROPS cab meets ISO 12117-2:2008 requirements.
- Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab posts and larger windows.
- A rear view camera is standard, and a right-side-view camera is optional.
- The new right-hand service platform design provides easy, safe, and quick access to upper service platform; the service platform steps use anti-skid punch plate to prevent slipping.
- The handrails comply with ISO 2867:2011 requirements.
- The lower frame meets ISO 15818:2017 lifting and tie-down requirements.
Read More
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 remember climate control fan and radio settings.
- Navigate quickly on the standard high-resolution 203 mm (8 in) touchscreen monitor or with the aid of the jog dial control.
- Protect your hammer from overworking. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds -- all to prevent wear and tear on the attachment and excavator.
- Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips in the touchscreen monitor.
- The Cat PL161 Attachment Locator is a Bluetooth device that makes finding your attachments and other gear quick and easy. The Cat App on your phone will locate the device automatically.
Read More
WORK IN COMFORT
- The Comfort cab has a wide seat that adjusts for operators of all sizes.
- 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 all shift long.
- Advanced viscous mounts reduce cab vibration by up to 50 percent 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.
- Use the standard radio’s USB ports and Bluetooth® technology to connect to personal devices.
