Benefits & Features
EFFICIENCY THROUGH TECHNOLOGY
• Up to 12% 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,
allowing the machine to find the correct gear that works best for
the engine and transmission. Pulling the load in the correct gear, in
most cases, results in lower engine load factor and lower fuel burn.
• Auto-stall assists in quickly bringing the transmission to an
operating temperature at startup when the machine is working in a
cold climate region.
• 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. Payload Estimator is an automatic feature when ordered with sequence assist.
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 FEATURES
• 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.
• Easy ground level access to fuel, water, and engine oil.

SAVE ON MAINTENANCE TIME
• The spacious cab features easy, intuitive controls and excellent

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.

Detect
On the surface, operators in the cabs of large mining equipment often cannot see if another machine or vehicle is too close for safe operation. Detect helps alleviate this potential safety hazard and can also be configured to provide valuable information about site conditions and other assets working in the area. Underground, continuous equipment movement on a longwall face can pose risks to those in the working area.
Equipment Management
Cat® Equipment Management gives you access to the data you need to keep your equipment on the job site and earning money. You can track equipment location and hours, monitor machine use and health, then take informed action that will keep your operation running smoothly, efficiently and profitably.
