MACHINES THAT UNDERSTAND YOUR BUSINESS
Business is all about profit. And nothing can be as profitable as the next generation Cat Excavators-323D3 ,320D3 and the 320D3GC. The 323D3 offers high productivity and superior fuel efficiency while the 320D3 offers high efficiency with low fuel consumption and the 320D3GC offers the lowest cost/hour of ownership.
Choose the machine to suit your business needs.
NEXT GENERATION CAT® EXCAVATORS
The biggest reasons to buy the 320D3 GC are simple
Built to Last
- 6-cylinder robust mechanical engine for improved reliability
- New modified X‐frame structure for longer life and durability
- Reinforced boom and stick with internal baffle plates for increased durability
- Greased track link between pins and bushings provides increased undercarriage life and noise reduction
Reduced Fuel Consumption with Optimum Performance
- The 320D3 GC offers up to 15% lower fuel consumption against previous comparable models
- Robust and easy to maintain fuel system filtration reduces risk of failure from contaminated fuel
- Caterpillar designed and built hydraulic pumps deliver superior performance
- Save energy with boom and stick regeneration valves
- Product Link™ comes standard so you can remotely monitor machine health by tracking fault codes, location, and hours. It is tamper-proof and secures data only for customer view on demand through the VisionLink® online interface
Lower Maintenance Costs
- Save time and money with extended service intervals for hydraulics and coolants
- New hydraulic oil filter with 50 percent more life
- 6,000-hour hydraulic oil service with 12% less oil required
- Quick and easy maintenance with most service locations accessible at ground level
- Filters grouped together to reduce maintenance time
- Pressure taps and S•O•SSM ports help maximize uptime
Superior Operator Comfort
- Operators will never feel as comfortable with an ergonomically designed cab with easy-to-operate controls
- Multiple seat and joystick adjustment options enhance comfort
- 25% increase in glass area for improved worksite visibility and enhanced productivity
- Reduced blind spots with convex profile glass for better safety
- Low-effort joystick controls reduce operator fatigue
Built-in Safety Features
- Hydraulic activation lever safely locks out all hydraulic functions
- Anti‐skid plating and countersunk bolts reduce slipping in severe conditions and during routine checks
- A full-length firewall separates the pump compartment from the engine
- A ground-level fuel cutoff switch shuts down the engine in an emergency
- Large steps on track frame and storage box for easy and safe climb
- Emergency exit in cab for improved operator safety
