REDFINING YOUR PROFIT POTENTIAL
Quick loading, high travel speeds and the ability to load and dump on the run yield fast cycle times, allowing Cat Wheel Tractor-Scrapers to consistently deliver high productivity at the lowest cost per ton.Increased ComfortErgonomic controls and a newly redesigned cab interior provide a more comfortable and efficient working environment all day long
Up To 8% Improved ProductivityImprovements in fuel efficiency and responsive APECS transmission controls deliver more productivity in most applications
Additional SafetyNew safety features help operators be more productive and work more efficiently all day long
Features may include:
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.
- 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.
- 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.
- 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.
- 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.
- The Cat C13 tractor engine meets U.S. EPA Tier 4 Final or EU Stage V 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.
