320 GC Hydraulic Excavator
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 20 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-level engine 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 the in-cab monitor.
- No required maintenance on the Cat Clean Emissions Module.
- Using Cat genuine oil and filters and doing your typical S∙O∙S monitoring will double the current service interval to 1,000 hours, giving you greater uptime to do more work.
- 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.
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.
SAFELY HOME EVERY DAY
- Access 100 percent of daily maintenance points from ground level
