Performance

  • The Cat® C7.1 ACERT™ electronic controlled engine meets U.S. EPA Tier 2/EU Stage II equivalent emission standards.
  • Constant engine speed control helps manage pump and engine rpm for improved fuel efficiency.
  • An electric fuel priming pump speed up starts and fuel system maintenance.
  • Boom and stick regeneration reduces fuel consumption.

Versatility

  • Cat attachments open you up to multiple money-making opportunities.
  • Demolition work is quick and easy with a Cat hammer, thumb, shear, or multiprocessor.
  • Utility and finishing work are fast and flawless with a Cat tilt bucket and compactor.
  • A coupler lets you swap between attachments in seconds without leaving the cab.
  • See the whole attachment line for your machine at www.cat.com/attachments.

Ease of Operation

  • The cab is ergonomically designed with easy-to-operate controls.
  • Multiple seat and joystick adjustment options enhance comfort.
  • Excellent work site visibility from the cab enhances productivity and safety.
  • Optimized low-effort joystick controls reduce operator fatigue.
  • Automatic climate control maximizes comfort.

Safety

  • The hydraulic activation lever safely locks out all hydraulic functions.
  • Anti‐skid plating and countersunk bolts reduce slipping in severe conditions and during routine checks.
  • A full-length firewall separates the pump compartment from the engine.
  • A ground-level cutoff switch shuts down the engine in an emergency.

Durability

  • The 323D2 has the largest structures in its size class.
  • The modified X‐frame structure provides long life and durability.
  • Heavy-duty booms and sticks are built for tough work.
  • Greased track link between pins and bushings increases undercarriage life and reduces noise.
  • An air precleaner protects the engine and extends engine life in dusty environments.

Maintenance

  • Most service locations can be accessed at ground level.
  • Fuel filters reduced from four to three with 500 hour service intervals help lower operational cost.
  • Filters are grouped together to reduce maintenance time.
  • Pressure taps and S·O·SSM ports help maximize uptime.

Technology

  • Integrated Cat technology solutions increase production and minimize operating costs.
  • Product Link™ reports key information from the machine to any location.
