MOVE MORE WITH LESS FUEL

        
  • Use up to 15% less fuel than the Cat 323D2 excavator.
    •     
  • Increase operator efficiency by up to 45% with a suite of Cat technologies that lower operator fatigue and your operating costs, including fuel consumption and daily maintenance.
    •     
  • Match the excavator to the job using power modes; let Smart mode automatically match engine and hydraulic power to your working conditions.
    •     
  • The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.
    •     
  • The electronically controlled, turbocharged engine can run on biodiesel up to B20 and meets Tier 3/Stage IIIA equivalent emission standards.
    •     
  • 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. 

TECHNOLOGY THAT GETS WORK DONE

        
  • Boost productivity up to 45% versus traditional grading with standard Cat Grade with 2D system – includes indicate-only and laser capability.
    •     
  • Cat Payload helps you achieve precise load targets to improve your operating efficiency. Pick up a load of material--with a bucket and thumb combination or grapple and clamshell attachments--and get a real-time weight estimate without swinging.
    •     
  • Combine Payload with VisionLink® and remotely manage your production targets.
    •     
  • Want a 3D system to improve your digging results? Caterpillar's single antenna global navigation satellite system (GNSS) makes it easy by giving you visual and auditory guidance to grade. Plus, you can create and edit designs on the touchscreen monitor while you’re on the job. If your application calls for a dual antenna system, it’s easy to upgrade.
    •     
  • Upgrade to our dual antenna GNSS for maximum grading efficiency. The system lets you create and edit designs on the touchscreen monitor while you’re on the job, or you can have the plan design sent to the excavator to make your work easier. Plus, you get added benefits of avoidance zones, cut and fill mapping, lane guidance, and augmented reality along with advanced positioning capability.
    •     
  • Already invested in another brand’s 3D system? No problem. Standard Cat technology like Grade with 2D can readily integrate with that system to give you the precise results you need.
    •     
  • Standard Grade Assist helps you 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.
    •     
  • Keep the tracks on 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.
    •     
  • All Cat Grade systems are compatible with radios and base stations from Trimble, Topcon, and Leica. Already invested in a grade infrastructure? You can install grade systems from Trimble, Topcon, and Leica onto the machine.

    •     
  • 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 an 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.
    •

  • Start the engine with the push of a button; use a Bluetooth key fob or Operator ID passcode.
    •     
  • Trouble cutting through tough material? Auto dig boost gives you an automatic power increase of 8% when you need it for better bucket penetration, shorter cycle times, and greater payloads.
    •     
  • Need more lift during your shift? Auto heavy lift gives you 8% more power exactly when you need it for as long as you need it.
    •     
  • Make moving the excavator much easier with Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers or pedals.
    •     
  • Make operating easier with the touch of a joystick button. Additional auxiliary relays allow you to power on or turn off a CB radio, beacon light, and even a dust suppression watering system without taking your hands off the joysticks.
    •     
  • Navigate quickly on the high-resolution monitor.
    •     
  • Protect your hammer tool from overheating and rapid wear. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds – all to extend the tool’s service life.
    •     
  • The Cat PL161 attachment locator is a Bluetooth device designed to let users know where their attachments are across all worksites, reduce the number of lost attachments, and plan for attachment maintenance and replacement. The PL161 integrates easily into VisionLink® for full fleet management of machines and attachments from one smartphone or tablet dashboard to view location and tracking details.
    •     
  • Save more time and energy with the available work tool recognition feature. A simple shake of the attached tool confirms its identity and ensures all the attachment settings (pressure, flow, and dimensions) are correct so you can work quickly and efficiently.
    •     
  • 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.

SAFELY HOME EVERY DAY

        
  • Cat Detect - People Detection helps protect the most valuable asset on any jobsite – people. The system uses smart cameras with depth sensors to provide the operator with visual and auditory alerts so he or she can take immediate action when a person is too close to the excavator.
    •     
  • Cat Command remote control enables equipment operators to work safely outside the machine when working in hazardous environments. Command offers the choice of handheld Consoles (line-of-sight) or long-distance virtual Stations (non-line-of-sight). Deep integration with machine systems enables efficiency and productivity by maintaining the use of in-cab technology* features (Grade, Payload, Assist, etc.).
    •     
  • Lift Assist helps you avoid tipping. With visual and auditory alerts, you’ll know if your load is within the excavator’s safe working range limits.  
    •     
  • 2D E-Fence prevents the excavator from moving outside of operator-defined set points; the system works with thumb and bucket combinations along with hammer, grapple, and clamshell attachments.
    •     
  • 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 or the Bluetooth key fobto enable the pushbutton starting feature.
    •     
  • The standard ROPS cab meets ISO 12117-2 2008 requirements.

  • 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 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.
    •     
  • Make service work easier and safer with optional inspection lighting. With the flip of a switch, lights will illuminate the engine, pump, battery, and radiator compartments to enhance visibility.
