High Performance with Lower Fuel Consumption

  • Use up to 25% less fuel than the 320F 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, twin-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

  • Boost productivity up to 45% versus traditional grading with the standard Cat GRADE with 2D system — includes indicate-only and laser capability.
    • Dig with real-time guidance on depth, slope, and horizontal distance to grade.
    • The 2D system is upgradable to Cat GRADE with Advanced 2D or Cat GRADE with 3D.
  • Standard Grade Assist:
    • Stay on grade — simply and effortlessly — with single-lever digging.
    • Set your desired bucket angle and let Bucket Assist automatically maintain the angle in sloping, leveling, fine grading, and trenching applications for easy, accurate, and fast jobs.
    • Keep your tracks on the ground in lifting and hard digging with Boom Assist.
    • Automatically stop excavator swing at operator-defined set points in truck loading and trenching applications with Swing Assist, which will help you use less effort and consume less fuel.
  • Standard Cat PAYLOAD on-board weighing system:
    • Achieve precise load targets and increase loading efficiency with on-the-go weighing and real-time estimates of your payload without swinging.
    • Track your daily productivity such as truck target weights and load/cycle counts.
    • Calibration can be performed in a matter of minutes.
    • Combine Payload with VisionLink® and remotely manage your production targets.
  • Upgrade to optional Cat GRADE with Advanced 2D:
    • Create and edit grade designs with ease on a second high-resolution 10 in (254 mm) touchscreen monitor.
  • Upgrade to optional Cat GRADE with 3D:
    • Create and edit designs with ease and see the front linkage’s full range of motion on a second high-resolution 10 in (254 mm) touchscreen monitor.
    • Know the excavator’s exact position relative to GPS and GLONASS systems.
    • The machine automatically compensates for excavator pitch and roll caused by sloping ground conditions.
  • Standard Product Link™ provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes, and other machine data on demand through VisionLink® online interface, helping you improve jobsite efficiency with lower operating costs.

Work in Comfort in the All-New Cab

  • Cab options 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.

  • 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.
  • 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..
  • 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.

Maintenance

  • Extended maintenance intervals reduce maintenance costs by 15% over the Cat 320F 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.

     - 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
