Advantages and Features

Be More Productive

        
  • Smart mode helps reduce fuel consumption by automatically matching the correct gear and hydraulic power to digging conditions.
  •     
  • 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 allows the machine to maintain a set top speed instead of relying on the top gear selector.
  •     
  • Auto-stall assists in quickly bringing the transmission to an operating temperature at startup 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 jobsite 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 fewer operator effort.

WORK IN COMFORT

Work in Comfort

        
  • Reduce up to 14 individual operator commands per cycle with
    Sequence Assist (optional attachment).
    • Steer with less effort using 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

Designed for Safety

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


EASY TO OPERATE

Easy to Operate

        
  • The spacious cab features easy, intuitive controls and excellent visibility
    . The cab provides a comfortable working environment for all-day
     operations.
  •     
  • 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.

INTERGRATED CAT TECHNOLOGIES

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

Execute Efficiency

        
  • The new tractor hydraulic on-demand fan helps assist in lower fuel consumption.
  •     
  • The Cat C13 tractor engine meets U.S. EPA Tier 4 Final/EU Stage
        V emission standards, or noncertified configurations that are
        equivalent to U.S. EPA Tier 2, or to U.S. EPA Tier 3/EU Stage IIIA, 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 Control (optional attachment) intelligently ensures the machine does not cut below grade in a cut area or overfill in the fill area.
