Benefits
BE MORE PRODUCTIVE
- Smart mode helps reduce fuel consumption by automatically matching the correct gear and hydraulic power to digging conditions.
- 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 allows the machine to maintain a set top speed instead of relying on the top gear selector.
- Auto-stall assists in quickly bringing the transmission to an operating temperature at startup when the machine is working in a cold climate region.
- Enhance productivity through the usage of Cat Payload with Sequence Assist.
- Cat Payload for scrapers is an earthmoving solution for optimal payload and jobsite 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 fewer 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 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 end stroke events and managing 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 a full-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 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).
- 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 jobsite.
- Shorten the learning curve for inexperienced operators with
Sequence Assist and Load Assist (included with Cat Grade
attachment).
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 and EU Stage V emission standards, or U.S. EPA Tier 2/equivalent to U.S. EPA Tier 3 and EU Stage IIIA 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 (optional attachment) intelligently ensures the machine does not cut below grade in a cut area or overfill in the fill area.
