BE MORE PRODUCTIVE

  • The Advanced Productivity Electronic Control System (APECS) allows the engine and transmission to communicate on a high level. This communication allows the machine to better utilize the power and torque the engine is producing. The net result is moving more material.
  • Use Ground Speed Control to set the desired top speed and the machine will find the gear that works best for the engine and the transmission, providing a lower fuel burn.
  • The Machine Speed Limit feature replaces Top Gear Selection.
  • Auto-Stall assists in quickly bringing the transmission to an operating temperature at start-up when the machine is working in a cold climate region.
  • Enhance productivity through the usage of Cat Payload with
        Sequence Assist.
  • Cat Payload for scrapers is an earthmoving solution for optimal payload and job site efficiency. Cat Payload achieves on-the-go weighing by using bowl lift cylinder pressure during the loaded haul segment. Cat Payload is optimized to be used with Sequence Assist, which provides increased productivity with less operator effort.




WORK IN COMFORT

  • Reduce up to 14 individual operator commands per cycle with 
    Sequence Assist.
  • Steer with less effort with the newly designed high-pressure steering
     system.
  • Enjoy interior improvements and a more ergonomic work environment
     with a 21% larger cab than the G Series cab.
  • Intuitive, ergonomic controls keep operators focused on their work.
  • Maintain desired cab temperature with automatic temperature control
    .

DESIGNED FOR SAFETY

  • Enhance an operator’s awareness of site surroundings with the Work
     Area Vision System (WAVS).
  • The seatbelt indicator provides visual and audible alerts when the seatbelt is not in use.
  • The Advanced Cushion Hitch enables the cushion hitch to prevent endstroke by predicting endstroke events and controlling the rate of damping, resulting in reduced hitch maintenance and an improved operator ride in rough conditions.

EASY TO OPERATE

  • The spacious cab features easy, intuitive controls and excellent 
    visibility. The cab provides a comfortable working environment for 
    all-day operation.
  • Cat Advanced Ride Management (ARM) seat suspension reduces
        endstroke movement of the load cylinder for a smoother ride.
  • Engine overspeed protection will automatically engage with no
        operator input when the machine is in eighth gear. The machine
        will assist in slowing the machine’s speed by canceling the throttle
        command and engaging the engine compression brake.

INTEGRATED CAT TECHNOLOGIES

  • Monitor, manage, and enhance job site operations.
  • Hit target grade faster and more accurately with Cat Grade technologies. Finish jobs in fewer passes and with less operator effort, saving you time and helping to increase profit.
  • Product Link™ collects machine data that can be viewed online
        through web and mobile applications (optional attachment).
  • Access information anytime, anywhere with VisionLink® – use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve safety and security on your
        jobsite.
  • Shorten the learning curve for inexperienced operators with
        Sequence Assist and Load Assist (included with Cat Grade attachment).

EXECUTE EFFICIENCY

  • The tractor's hydraulic on-demand fan helps reduce fuel consumption.
  • The Cat C13 tractor engine and C9.3 scraper engine meet U.S. EPA
        Tier 4 Final and EU Stage V emission standards, or U.S. EPA Tier 2/
        equivalent to U.S. EPA Tier 3 and EU Stage IIIA emission standards,
        contributing to lower fuel consumption.
  • Using draft-arm overflow guards diverts material away from the bowl, preventing material from getting caught between the draft arms and the bowl sides.
  • Cat Grade (optional attachment) intelligently ensures the machine
        does not cut below grade in a cut area or overfill in the fill area.
