  • The C18 engine meets U.S. EPA Tier 2/EU Stage II equivalent or Tier 3/Stage IIIA equivalent emission standards.
  • Cat® electrohydraulic system enables the machine to consume less fuel than the standard 390D L while delivering the same high level of production.
  • The emissions technology is transparent – no action required from the operator and no stopping for regeneration.
  • Automatic engine speed control lowers rpm based on load for reduced fuel consumption.
  • Power modes help you more actively manage fuel consumption.

    * Product Link™ field results.


  • Cat technologies increase production, minimize operating costs, and optimize return on investment.
  • Cat Payload tells you how much material you are loading to make you more money.
  • VisionLink® provides wireless access to machine operating data such as location, hours, idle time, fuel usage, productivity, and diagnostic codes to optimize performance.
  • Cat GRADE provides real-time cut and fill information to assist you in attaining grades and slopes more quickly and accurately.


  • Routine maintenance items like grease points and fluid taps are easy to reach at ground level.
  • The side-by-side cooling system enables easy cleaning.
  • Multiple S∙O∙S ports and pressure diagnostic taps help prevent maintenance downtime.


  • The cab is more comfortable and 3 dB(A) quieter than 390D L.
  • Joystick consoles and armrests are adjustable. Seats are adjustable and feature air suspension and heated and cooled options.
  • The LCD monitor is easy to navigate and programmable in 44 languages.


  • Demolition work is quick and easy with a Cat shear or multiprocessor.
  • Quarry work is no problem with a purpose-built Cat bucket and hammer.
  • A Cat coupler lets you swap between attachments in seconds without leaving the cab.
  • Tool control option remembers pressures and flows for up to 20 tools to enhance uptime.


  • Booms and sticks are built for long service.
  • Box-section structures with multi-plate fabrications, castings, and forgings are used in high-stress areas.
  • Greased track link between pins and bushings increases undercarriage life and reduces noise.


  • Smart refuel fills the machine quickly from an external fuel source and automatically stops when the fuel tank is full or the fuel source is empty.
  • The rearview and sideview cameras enhance visibility to help make operators more effective and efficient.
  • Extended hand and guard rails allow for safer climbing to the upper deck, and anti-skid plates reduce slipping hazards in all types of weather conditions.
