DESCRIPTION

Caterpillar offers partial wheel tractor-scraper power units designed for specialty machines that complement the traditional Cat® product line. These tractor-only configurations are available for purchase directly from Caterpillar OEM Solutions. They can be leveraged for a variety of final machines, including water pulls, elevating scrapers, lowboy trailer power units, and more. With improvements in productivity combined with enhancements in operator comfort and new safety features – Powered Access System and effective wet disc brakes – this machine offers high returns on time and investment.

Features

  • WORK IN COMFORT

    • Steer with less effort with the newly designed high-pressure steering system.
    • Enjoy interior improvements and a more ergonomic work environment.
    • Intuitive, ergonomic controls with multifunction display keep operators focused on their work.
    • Maintain desired cab temperature with automatic temperature control.

  • EASY TO OPERATE

    • 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.

  • BE MORE PRODUCTIVE

    • The Advanced Productivity Electronic Control System (APECS) allows the machine to better utilize engine power and torque.
    • Set the desired top speed with Ground Speed Control, and the machine will find the gear that works best for the engine and the transmission, providing a lower fuel burn in speed reduced areas.
    • 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 working in colder climates.

  • DESIGNED FOR SAFETY

    • Get in and out of the cab easier with the new powered access ladder system.
    • Enhance the operator’s awareness of site surroundings with the optional Work Area Vision System (WAVS).
    • Ground-level access to fuel fill and several maintenance points for easier and safer service.
    • Seat belt indicator provides visual and audible alerts when the seat belt is not in use.
    • Wide brake shoes and brake drums improve brake performance and reduce brake and drum wear.
    • Secondary brakes engage automatically if service pressure drops
    • Parking Brake features a spring-applied, hydraulic pressure released mechanism that operates the service brakes.

  • SUPPORTED BY THE CAT DEALER NETWORK

    • Full support of Cat dealer and parts network.
    • Eligible for Equipment Protection Plans (EPP) & Customer Value Agreements (CVAs).
