Overview

REDEFINING YOUR PROFIT POTENTIAL

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.

Benefits

Increased

Ergonomic controls and a newly redesigned cab interior provide a more comfortable and efficient working environment all day long

Improved

Improvements in fuel efficiency and responsive APECS transmission controls deliver more productivity in most applications

Additional

New safety features help operators be more productive and work more efficiently all day long

Features at a Glance

BE MORE PRODUCTIVE

BE MORE PRODUCTIVE

Advanced Productivity Electronic Control System (APECS) allows the engine and transmission to communicate on a high level. This communication allows the machine to utilize better 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.
Boost productivity with the Cat Payload feature (optional attachment). Cat Payload is an automatic feature when ordered with Sequence Assist.
Cat Payload for scrapers is an earthmoving solution for optimal payload and job site 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 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

Enhance an operator’s awareness of site surroundings with the
Work Area Vision System (WAVS).
Seat belt indicator provides visual and audible alerts when the seat
belt is not in use.
Advanced Cushion Hitch allows the cushion hitch to prevent end
stroke 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.

INTEGRATED 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.
Vision 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 job site.
Shorten the learning curve for inexperienced operators with Cat grade control and 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 meets U.S. EPA Tier 4 Final or EU Stage V emission standards, 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.
