627K Wheel Tractor-Scraper

627K Open Bowl Scraper

DESCRIPTION

Quick loading, high travel speeds and the ability to load and dump on the run yield fast cycle times, allowing Cat Wheel Tractor-Scrapers to consistently deliver high productivity at the lowest cost per ton.

BE MORE PRODUCTIVE

  • Up to 8% improvement in productivity.
  • 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.
  • Machine Speed Limit feature replace stop 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.
  • Boost productivity with the Payload Estimator feature (optional
    attachment). Payload Estimator is an automatic feature when
    ordered with Sequence Assist.
  • 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.

EFFICIENCY THROUGH TECHNOLOGY
WORK IN COMFORT

WORK IN CONTROL

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

  • 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
    Work Area Vision System [WAVS (optional attachment)].
  • Differential lock engagement protection (standard) prevents
    the operator from engaging the differential lock when damage
    can occur.
  • Seat belt indicator provides visual and audible alerts when the seat belt is not in use.

DESIGNED FOR SAFETY
EASY TO OPERATE

EASY TO OPERATE

  • Control the slip of the tractor tires with tire spin reduction
    (standard).
  • The spacious cab features easy, intuitive controls and excellent
    visibility. The cab provides a comfortable working environment for
    all-day operation.
  • Equipped with advanced cushion hitch software, the Cat Advanced
    Ride Management (ARM) seat suspension reduces end stroke
    movement of the load cylinder for a smoother ride.

Features

  • INTEGRATED CAT TECHNOLOGIES

    • 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 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

    • The new tractor hydraulic on-demand fan helps assist in lower fuel consumption.
    • Use fuel economy mode to assist in fuel savings.
    • The Cat C13 tractor engine and the Cat 9.3 scraper engine emit equivalent to U.S. EPA Tier 2/EU Stage II or U.S. EPA Tier 3/ EU Stage III, contributing to lower fuel consumption.
    • Using draft-arm overflow guards diverts material away from the bowl, retaining material and limiting spills onto the rear of the scraper.
    • No operator input is required with engine overspeed protection.
    • Cat Grade Control (optional attachment) intelligently ensures the machine does not cut below grade in a cut area or overfill in the fill area.
