Benefits & Features

BE MORE PRODUCTIVE

BE MORE PRODUCTIVE

    • Up to 7% additional elevator torque.
    • Up to 50% improvement in chain life.
    • Enhanced elevator drive sprocket for reduced chain wear.Improved scissor-style chain tension system for decreased
      sprocket wear, chain wear, and chain jumping.
    • Cat C13 engine offers increased power density with a combination
      of proven electronic, fuel, and air systems.
    • 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.
    • 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.
    • 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.
    • Cat Payload Estimator for scrapers is an earthmoving solution for
      optimal payload and jobsite efficiency. Payload Estimator achieves on-the-go weighing by using bowl lift cylinder pressure during the loaded haul segment. Payload Estimator is optimized to be used with Sequence Assist, which provides increased productivity with less 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

    • Brakes are hydraulically actuated wet disc brakes for the tractor
      and scraper.
    • Get in and out of the cab easier with the new powered access
      ladder system (optional attachment).
    • Enhance an operator’s awareness of site surroundings with the
      optional Work Area Vision System (WAVS).
    • Seat belt indicator provides visual and audible alerts when the seat
      belt is not in use.
    • Ground level, engine shut-off switch stops all fuel to the engine
      when activated and shuts down the machine.
    • Advanced Cushion Hitch allows the cushion hitch to prevent
      end stroke by having the ability to predict end stroke events
      and manage 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 operation.
    • Cat Advanced Ride Management (ARM) seat suspension reduces
      end stroke 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 speed by canceling the throttle
      command and engaging the engine compression brake.

INTEGRATED CAT TECHNOLOGIES

INTEGRATED CAT TECHNOLOGIES

    • Monitor, manage, and enhance jobsite 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 Vision Link®– 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 Load Assist (optional attachment).

EXECUTE EFFICIENCY

EXECUTE EFFICIENCY

    • The new tractor hydraulic on-demand fan helps assist in lower fuel consumption.
    • The Cat C13 tractor engine emits equivalent to U.S. EPA Tier 2 and EU Stage II and U.S. EPA Tier 3 and EU Stage IIIA, contributing to lower fuel .
    • 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.
