Wheel Tractor-Scraper K Series Operator Testimonial
BE MORE PRODUCTIVE
- 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. - Machine Speed Limit feature replace stop 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.
WORK IN CONTROL
- Reduce up to 14 individual operator commands per cycle with
Sequence Assist (optional attachment). - Steer with less effort with 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
- 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
Work Area Vision System [WAVS (optional attachment)]. - Differential lock engagement protection (standard) prevents
the operator from engaging the differential lock when damage
can occur. - Seat belt indicator provides visual and audible alerts when the seat belt is not in use.
EASY TO OPERATE
- Control the slip of the tractor tires with tire spin reduction
(standard). - The spacious cab features easy, intuitive controls and excellent
visibility. The cab provides a comfortable working environment for
all-day operation. - Equipped with advanced cushion hitch software, the Cat Advanced
Ride Management (ARM) seat suspension reduces end stroke
movement of the load cylinder for a smoother ride.
