FEATURES AT A GLANCE
PRODUCTIVITY
- 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. - 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 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.
OPERATOR COMFORT AND CONTROL
- 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.
BUILT-IN 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). - 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 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.
EASE OF OPERATIONS
- 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.
CAT TECHNOLOGY
- Monitor, manage, and enhance jobsite 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).
EFFICIENCY
- The new tractor hydraulic on-demand fan helps assist in 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.
