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.
Continuously improved user interface allows for intuitive navigation, minimizing performance interruption with the easy-to-use touchscreen menu.
Use the in-monitor QR code to learn about machine and technology features through a full suite of “how-to” videos.
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

Daily maintenance at ground level, longer filter lifespan, and extended and synchronized service intervals help reduce maintenance costs.
The electrohydraulic system eliminates the need for pilot lines and filter.
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 - keeping your machine on the job for longer periods of time.
The hydraulic oil filter provides high filtration performance, anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3,000 hour replacement interval.
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 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.
VisionLink™ provides actionable data insights for all assets – regardless of fleet size or equipment manufacturer.* Review equipment data from your desktop or mobile device to maximize uptime and optimize assets. Equipment management features provide up-to-date asset tracking of your entire fleet. You can track asset location, operating hours, fuel level, health issues, and overall utilization. Monitor equipment health with fault codes, fluid analysis, and inspection due dates. It's all about making informed, data-based decisions to help reduce operating costs. Productivity management features enable you to analyze overall job site performance. You'll be able to track tonnage moved, production targets, and payload, as well as Grade 3D and compaction data. These vital metrics help you to reduce costs and improve jobsite operational efficiency.
Save fuel with Automatic Engine Control (AEC). It reduces engine speed when the machine is not under load to minimize fuel consumption.

* Data field availability can vary by equipment manufacturer.

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).

Sustainability

The Cat® C4.4 engine meets U.S. EPA Tier 4 Final and EU Stage V emission standards.
Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) and are compatible* with ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)*** or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details.
Auto Engine Speed Control helps reduce unnecessary fuel burn and greenhouse gas emissions by allowing the engine to automatically go into idle mode when the machine is not working.
When engaged, one-touch idle helps operators conserve fuel and reduce greenhouse gas emissions by lowering engine speed when the machine is under no load and return to normal operating speed when desired.
Engine Idle Shutdown Timer reduces fuel burn, greenhouse gas emissions and unnecessary idle time by shutting down the machine after a pre-set idling period.
VisionLink® displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
Don't waste fuel idling. Cat VisionLink® online fleet monitoring helps you manage idle time and reduce fuel burn and greenhouse gas emissions.
Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
Cat Scheduled Oil Sampling (S•O•S^SM) Services helps reveal excessive wear, contaminated fluids or other “unseen” issues that can shorten component life. In many cases, you can extend oil and coolant change intervals by using fluid monitoring. Consult your Cat dealer or the machine's operation and maintenance manual for more information.
A well-trained operator is worth the investment. Skilled operators benefit your bottom line by maximizing productivity, avoiding costly downtime, and maintaining jobsite safety – which can help to improve fuel efficiency and reduce greenhouse gas emissions.

*While Caterpillar engines are compatible with these alternative fuels, some regions may not allow their use.
**Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
***Engines with no aftertreatment devices are compatible with higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).
