Performance

  • The Cat® C7.1 mechanically controlled engine meets U.S. EPA Tier 2 and EU Stage II equivalent emission standards.
  • The low-pressure fuel system allows the engine to be more robust in areas with low-quality fuel.
  • The high-efficiency main pump delivers superior power for best-in-class performance.
  • Economy mode burns less fuel than the previous generation 320D2/D2 L with no loss in lift or dig force.
  • The variable-speed fan with viscous clutch reduces fuel consumption.

Versatility

  • Utility and finishing work are fast and flawless with Cat buckets, thumbs, and compactors.
  • Demolition work is quick and easy with Cat hammers, grapples, shears, and multi-processors.
  • Cat couplers let you swap between attachments in seconds without leaving the cab.
  • See the whole money-making attachment lineup at www.cat.com/attachments.

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 fuel cutoff switch shuts down the engine in an emergency.

Durability

  • 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.

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.

Maintenance

  • Most service locations can be accessed at ground level.
  • The number of fuel filters are reduced from four to two with 500 hour service intervals to 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.
