Enjoy wide spacing between consoles for a more comfortable environment.
Sit in new, wide seats that adjust for operators of all sizes (heated option available).
Get in and out of the cab easier using the tip-up left console (in Deluxe cab only).
Control the excavator comfortably with easy-to-reach controls located in front of you.
Standard automatic climate control keeps you at the right temperature throughout your shift.
Improved viscous mounts reduce cab vibration by up to 50% over our previous excavator models.
Stow your gear with plenty of in-cab storage behind and beneath the seat, overhead, and in the consoles. A cup holder, document holder, bottle holder, and coat hook are included.
The standard radio has USB ports and Bluetooth® technology enabled to connect your device and make hands-free calls.

BUILT FOR LONG TERM PRODUCTION

Protect hydraulic components in cold weather. The auto warm-up feature speeds hydraulic oil warming in cooler temperatures.
The fuel system is protected from contamination of fuel by three levels of filtration.
Bottom guarding protects engine and hydraulic components from damage while swinging and traveling.
The hydraulic tank with a new oval shape is designed to improve stress resistance.
The strong X-structure lower frame carries loads from the excavator's upper structure to the track.
Travel motor hydraulic lines are routed inside of the frame to protect them from damage.
The sloped track frame design prevents mud and debris from accumulating and damaging tracks.
The grease lubricated tracks have grease sealed between the pin and bushing to prevent debris from entering and reducing life.
The track rollers are sealed to prevent dirt and debris causing wear of internal components.
A bolt-on track guiding guard helps maintain track alignment while traveling or working on slopes.

SIMPLE TO OPERATE

You can navigate quickly on the standard high-resolution 203 mm (8 in) touchscreen monitor, or with the optional 254 mm (8 in) touchscreen monitor, or with the aid of the jog dial control.
A second 254 mm (10 in) monitor is available for the advanced grade control.
Start the engine with a push button; use a Bluetooth key fob, smartphone app, or the unique Operator ID function.
Match the excavator's operation to your digging style by adjusting the joystick response and programming the function of each joystick button.
Protect your hammer from overworking. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds -- all to prevent wear and tear on the attachment and excavator.
The Cat PL161 Attachment Locator is a Bluetooth device that makes finding your attachments and other gear quick and easy. The excavator's onboard Bluetooth reader or Cat App on your phone will locate the device automatically.
Save more time and energy with the available work tool recognition feature. A simple shake of the attached tool confirms its identity; it also ensures all the attachment settings are correct so you can get to work quickly and efficiently.
Auto Dig Boost increases power by up to 8% for better bucket penetration, shorter cycle times, and greater payloads.

LOWER MAINTENANCE COSTS

Extended maintenance intervals reduce maintenance costs by 20% over the 323D2 series excavator (savings calculated over 12,000 machine hours).
Reversing electric cooling fans make it easy to clean radiator, oil coolers, and condensers.
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.
An all-new engine air cleaner with integrated pre-cleaner has twice the life of radial seal air cleaners.
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% longer than previous filter designs.
Track your excavator's filter life and maintenance intervals via the in-cab monitor.
Check engine oil level quickly and safely with the new engine oil dipstick located on ground level.
S·O·S ports with extended sampling intervals are on ground level, simplifying maintenance and allows for quick easy extraction of samples for fluid analysis.

SAFELY HOME EVERY DAY

Work safely under structures or near traffic with the standard 2D E-fence feature integrated right out of the factory, which prevents any part of the excavator from moving outside operator-defined set points to avoid hazards and jobsite accidents.
Access 100% of daily maintenance points from ground level – no need for you to climb on top of the excavator.
Keep your excavator secure. Use your PIN code on the monitor, the Bluetooth key fob, or your smartphone to enable the pushbutton starting feature.
The standard ROPS cab meets ISO 12117-2 2008 requirements.
Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab posts and larger windows.
A rearview camera is standard and upgradable to an optional 360° visibility camera for visibility all around the excavator, allowing the operator to easily visualize objects and personnel around the excavator in a single view.
The new right-hand service platform design provides easy, safe, and quick access to upper service platform; the service platform steps use anti-skid punch plate to prevent slipping.
The handrails comply with ISO2867 requirements.
