Features At A Glance

Latest Features

Cab Monitor Improvements

Continuously improved user interface allows for intuitive navigation, minimizing performance interruption with the easy-to-use touchscreen menu.
Identify apps quickly with a grid list view, abbreviated app names, and categorized menu options.
A notification center keeps important information visible to the operator, and displays messages without shrinking the camera view.
Color coded notifications set critical messages apart from the rest.
Use the in-monitor QR code to learn about machine and technology features through a full suite of “how-to” videos.

Not all features are available in all regions. Please check with your local Cat dealer for specific offering availability in your area.
Build Number: 05E

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 L 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 L 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.
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.
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.
