BE MORE PRODUCTIVE

Additional elevator torque.

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 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

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

Enhance an operator’s awareness of site surroundings with the optional
Work Area Vision System (WAVS).

The seatbelt indicator provides both 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

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

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.

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 job site.

Shorten the learning curve for inexperienced operators with Sequence Assist and Load Assist (included with Cat Grade
attachment).

EXECUTE EFFICIENCY

The tractor hydraulic on-demand fan helps assist in lower fuel consumption.

The Cat C13 tractor engine and C9.3 scraper engine meet U.S. EPA
Tier 4 Final and EU Stage V emission standards, or equivalent to
U.S. EPA Tier 2, or equivalent to U.S. EPA Tier 3 and EU Stage IIIA.

Cat Grade Control (optional attachment) intelligently ensures the machine does not cut below grade in a cut area or overfill in the fill area.
