Easy to Operate

    
• The machine’s electrohydraulic system allows accurate bucket control for maximum precision.

    

• Start the engine with a push button.

    

• Navigate quickly on the high-resolution 203 mm (8 in) touchscreen monitor

    

• Control the excavator comfortably with easy-to-reach controls all located in front of you.

    

• Program your preferences for power mode, joystick pattern, and joystick response using Operator ID. The excavator will automatically remember your selections.

Easy to Maintain

    
• Do daily maintenance at ground level.

    

• Up to 20% less maintenance cost than the 320D2 GC due to enhanced filters and extended and synchronized service intervals (savings calculated over 12,000 machine hours).

    

• The air intake filter with precleaner has double the dust holding capacity of the previous air intake filter. Final drive and swing drive oil is double the initial service life – from 250 to 500 hours.

    

• Fuel filters are synchronized to be changed at 1,000 hours – double the interval from the previous filters.

    

• The 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.

    

• Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to help increase undercarriage life.

    

• Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.

    

• Advansys™ bucket tips increase penetration and improve cycle times. Tip changes can be done quickly with a simple lug wrench instead of a hammer or special tool, improving safety and uptime.

    

• S·O·S^SM oil sampling ports are on ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.

Low Owning and Operating Costs

    
• The excavator uses up to 15% less fuel than the 320D2 GC in similar applications.

    

• Match the excavator to the job with a choice of two modes: Power and Smart. Power mode provides full-time maximum output. Smart mode automatically matches engine and hydraulic power to digging conditions to help conserve fuel without impacting production.

    

• Save fuel with Automatic Engine Control (AEC). It reduces engine speed when the machine is not under load to minimize fuel consumption.

Reliable Performance

    
• A versatile machine that performs well in bucket and hammer applications.

    

• Booms and sticks are robotically welded and checked ultrasonically to ensure maximum durability.

    

• Reliable and durable and built on classic, proven components.

    

• The Cat C4.4 engine and electrohydraulic system work in sync to help you move plenty of material while using less fuel.

    

• Fast cycle times give you excellent productivity.

    

• A hammer-ready valve is standard for added versatility.

    

• Two levels of fuel filtration protect the engine from contaminated diesel fuel.

    

• Cat undercarriage is built strong to absorb jobsite stresses for enhanced performance and durability.

    

• General duty buckets are designed for fast material discharge and cleaning.

    

• Work up to 4500 m (14,760 ft) above sea level with engine power derate above 3000 m (9,840 ft).

    

• Standard high-ambient temperature capability is 52°C (125°F) with cold start capability at -25°C (-13°F).

Work in Comfort

    
• The cab has a wide seat that adjusts to suit individual operator preferences.

    

• Standard automatic climate control helps keep you comfortable all shift long.

    

• Excellent work site visibility from the cab enhances productivity and safety.

    

• Optimized low-effort joystick controls reduce operator fatigue.

    

• Convenience features include a radio, auxiliary port for headphones, and a USB port for connecting and charging devices; a 24V DC outlet makes phone charging even faster.

    

• Use the radio’s Bluetooth® technology to make hands-free calls.

    

• The cup holder and storage space in front of the controls can hold large cups and wide cell phones; storage behind the seat can hold a large lunchbox and other items.

Enhanced Safety

    
• Access daily maintenance points from ground level with the exception of the engine oil level – no need to climb on top of the excavator to check filters or grease linkage.

    

• An optional ISO certified Rollover Protective Structure (ROPS) cab is offered in some regions to help protect the operator in the event of a rollover.

    

• Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab posts and larger windows.

    

• An optional rearview camera enhances visibility.

    

• Anti-skid plating on the service platform helps prevent slipping.

    

• The handrails meet ISO 2867:2011 requirements for added safety.

    

• Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the push button starting feature.

    

• Enhance jobsite safety. Add a swing alarm to alert people when you're rotating from trench to stockpile and back again.
