657 Wheel Tractor-Scraper

657

DESCRIPTION

Cat® Wheel Tractor-Scraper 657 twin engine has the power to boost productivity by utilize push-pull loading. Combine this ability with improvements in productivity, enhancements in operator comfort, and new safety features – Powered Access System and effective wet disc brakes – and you have a machine offering high returns on profit and time.

BE MORE PRODUCTIVE

  • Up to 6% of improvements in productivity.
  • Advanced Productivity Electronic Control System (APECS) allow 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.
  • 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.

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 onyour jobsite.
  • Product Link™ collects machine data that can be viewed online through web and mobile applications (optional attachment).

EXECUTE EFFICIENCY

  • The Cat C18 tractor and C15 scraper engines meets U.S. EPA Tier 4 Final or EU Stage V emission standards, contributing to lowerfuel 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.
  • The new tractor hydraulic on-demand fan helps assist in lower fuel consumption.

Features

  • 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 multifunction display keep operators focused on their work.
    • Maintain desired cab temperature with Automatic
      Temperature Control.

  • DESIGNED FOR SAFETY

    • 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).
    • Ground level access to fuel fill and daily maintenance points.
    • Seat belt indicator provides visual and audible alerts when the
      seatbelt is not in use.
    • 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

    • Cat Advance 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.
