Benefits

Purpose-Built Coal Bowl

• Large capacity coal bowl scrapers are longer and higher than
standard open bowl scrapers.
• Purpose-built coal bowl dual engine scrapers deliver faster cycle
times with maximum payloads.
• High ground speed provides the ability to manage stockpiles.
• Machine is designed for loading, hauling, and compaction for
complete functionality.
• Work effectively in poor underfoot conditions and climb slippery
piles and loose coal with all-wheel drive (AWD).
• Coal bowl scrapers provide effective coal compaction, which
reduces the risk of spontaneous combustion in coal stockpiles by
eliminating the air spaces.
• Specialty coal bowl scrapers are optimized for maximum machine
productivity and efficiency.

Be More Productive

        
  • The Advanced Productivity Electronic Control System (APECS)
        enables communication between the engine and transmission to
        effectively optimize power and torque output. This integration
        results in enhanced efficiency with a 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 top gear selector.
  •     
  • 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.








Work in Comfort

        
  • Steer with less effort with the newly designed high-pressure steering
     system.
  •     


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




  • Enjoy interior improvements and a more ergonomic work environment
     with a 21% larger cab than the 657 G-Series cabs.
  •     






  • Intuitive, ergonomic controls with a multifunction display keep operators
     focused on their work.
  •     








  • Maintain desired cab temperature with automatic temperature control
    .

Designed for Safety

        
  • The powered access ladder, included as a standard feature, enables easier entry and exit from the cab.
  •     
  • Enhance the operator’s awareness of the site surroundings with the
        Work Area Vision System (WAVS).Convenient ground-level access to fuel fill and multiple
        maintenance points, ensuring safer and more efficient service.
  •     
  • Seat belt indicator provides visual and audible alerts when the seat belt is not in use.
  •     
  • The fuel fill, fuel filter, engine oil filter,  engine oil change, and water drain are easily accessible at ground level.






Easy to Operate

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




Integrated Cat Technologies

        
  • 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 job site
    .
  •     


  • Product Link™collects machine data that can be viewed online through web and mobile applications.

Execute Efficiency

        
  • The Cat C18 tractor and C15 scraper engines meet U.S. EPA Tier 4 Final or EU Stage V emission standards, contributing to lower fuel consumption.
  •     
  • The tractor hydraulic demand fan helps lower fuel consumption.
  •     
  • Monitor, manage, and enhance jobsite operations.
