INTEGRATED CAT TECHNOLOGIES
EXECUTE EFFICIENCY
- Advanced Productivity Electronic Control System (APECS) allows the engine and transmission to communicate on a high level. This communication enables 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 regions.
- 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.
- Steer with less effort with the newly designed High-Pressure Steering system.
- Reduce up to 14 individual operator commands per cycle with
Sequence Assist (optional attachment). - Enjoy interior improvements and a more ergonomic work environment
with a 21% larger cab than the 657 G-Series cabs. - Intuitive, ergonomic controls with multifunction display keep operators focused on their work.
- Maintain desired cab temperature with Automatic
Temperature Control.
- Get in and out of the cab easier with the new powered access
ladder system. - Enhance an operator’s awareness of the site surroundings with the
Work Area Vision System (WAVS). - Convenient ground-level access to fuel fill and multiple
maintenance points, ensuring safer and more efficient service. - Seat belt indicator provides visual and audible alerts when the seat belt is not in use.
- The fuel fill, fuel filter, engine oil filter, engine oil change, and water drain are easily accessible at ground level.
- Cat Advance 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.
- The spacious cab features easy, intuitive controls and excellent
visibility. The cab provides a comfortable working environment for
all-day operation.
- Access information anytime, anywhere with VisionLinkTM –
use it to make informed decisions that boost productivity, lower
costs, simplify maintenance, and improve safety and security
on your jobsite. - Product Link™ collects machine data that can be viewed online
through web and mobile applications (optional attachment). - 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. - Monitor, manage, and enhance jobsite operations.
- The Cat C18 tractor and C15 scraper engines meet U.S. EPA Tier 4 Final and EU Stage V emission standards, contributing to
lower fuel consumption. - The tractor hydraulic on-demand fan helps assist in lower
fuel consumption. - Cat Grade (optional attachment) intelligently ensures the machine
does not cut below grade in a cut area or overfill in the fill area.
