High Performance with Lower Fuel Consumption


  • Use up to 20% less fuel than the 323F excavator.

  • Increase operator efficiency by up to 45% with a suite of Cat Connect technologies that lower operator fatigue and your operating costs, including fuel consumption and daily maintenance

  • Match the excavator to the job using power modes including new Smart mode that automatically matches engine and hydraulic power to your digging conditions.

  • The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for your precise digging requirements.

  • The electronically controlled, turbocharged engine meets U.S. EPA Tier 4 Final and EU Stage IV emission standards using a transparent aftertreatment system that requires no operator input or downtime

  • Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.

  • Don't let the temperature stop you from working. The excavator has a standard high ambient temperature capability of 52º C (125º F) and cold start capability of -18º C (0º F). An optional -32º C (-25º F) cold start package is available.



 


Boost Efficiency and Boost Productivity with Integrated Cat Connect


 


Work in Comfort in the All-New Cab


  • Two cab options – Deluxe, and Premium– let you choose the level of comfort you need.

  • Enjoy wide spacing between consoles for a more spacious comfortable environment.

  • Sit in new, wide seats that adjust for operators of all sizes (heated and heated/cooled options are available).

  • Get in and out of the cab easier using the tip-up left console (in Deluxe and Premium cabs 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 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 Life


  • 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 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 rebuild-able and 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 8 in (203 mm) touchscreen monitor or with the optional 10 in (254 m) touchscreen monitor or with the aid of the jog dial control.

  • A second 10 in (254 mm) monitor is available for the advanced grade control.

  • Easy keyless push-to-start engine using your Bluetooth key fob, or your smartphone to enable the pushbutton start feature.

  • Match the excavator's operation to your digging style by adjusting the joystick response and programming the function of each joystick button.

  • Easily use the monitor to change the joystick pattern from the cab. You can choose two-way or four-way patterns options. Store your pattern preference and let the machine automatically set the pattern when you log in with your unique Operator ID.

  • Not sure how a function works or how to maintain the excavator? Always have the operator's manual at your fingertips in the touchscreen monitor..



 


Maintenance


  • Extended maintenance intervals reduce maintenance costs by 15% over the Cat 323F excavator. (15% savings calculated over 12000 machine hours.)

  • Reversing electric cooling fans make it easy to clean radiator, oil coolers, and condensers.

  • 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 3000 hour replacement interval – 50% longer than previous filter designs.

  • Track your excavator's filter life and maintenance intervals can via the in-cab monitor.

  • Check engine oil level quickly and safely with the new engine oil dip stick 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.



 


Safety


  • 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, avoiding hazards and jobsite accidents.

  • Access 100% of daily maintenance points from ground level – no need for you to climb on top of excavator.

  • 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 pillars, larger windows, and a flat engine hood design.

  • The standard hydraulic lockout lever isolates all hydraulic and travel functions in the lowered position.

  • Ground level shut-off switch stops all fuel to the engine when activated and shuts down the machine.

  • 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.

  • 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 ISO 2867 requirements.
