Caterpillar offers partial machines and systems, working with Cat dealers and Original Equipment Manufacturers (OEMs) to provide specialty machines for specific applications. Bare chassis trucks (WTR models) can be ordered with or without hoist cylinders and most product options are identical to the dump truck models. Typically, these models come equipped with the higher Tractor ROPS certification ratings needed for specialty machines including water trucks, tow trucks and fuel and lube trucks. You'll find these partial machine configurations are used in construction, demolition, waste, material handling, and mining industries and allow you to purchase complete solutions from your Cat dealer, using Cat equipment every step of the way. The Cat Water Delivery System (WDS) is available as an optional attachment with the 777G WTR and 785D WTR Off-Highway Truck Bare Chassis and includes factory installed controls in the cab, a hydraulic pump and motor, a water pump and stainless steel spray heads. Whether your goal is dust control or haul road maintenance, the Cat WDS is designed to put water to the ground in a controlled, intelligent way. The simple to operate automated system allows you to concentrate on more important safety issues like traffic, personnel and road conditions. You'll also find that the Cat WDS not only improves safety, but also reduces truck maintenance costs, conserves water and provides significant fuel savings to hlep your bottom line.

  • Cutting Your Fuel Costs

    A strategy for lowering your cost per ton

    Economy Modes

    • Standard Economy Mode - G Series can save fuel by adjusting engine power through this newly adjustable economy mode. Adjust the power based on your site, fleet and economic conditions. The power can be reduced from 0.5 to 15 percent.
    • Adaptive Economy Mode - New for G Series - this economy mode requires a baseline for production from you using the Advisor display. As the truck transits the haul cycle, it is constantly evaluating its ability to meet your baseline in a reduced power rating. Where full power is needed, full power is applied, where reduced power works, reduced power is applied. It’s fully automatic with no special operation required.

    The 777G introduces several key fuel conservation features:

    • Auto Neutral Idle - as the 777G idles in a forward gear, the transmission will automatically slip in and out of a neutral state to avoid stalling the torque converter and raising engine rpm.
    • Engine Idle Shutdown - when your G Series truck is in park and idles for more than a preset time, the truck will initiate engine shutdown to conserve fuel. This feature can be time adjusted or turned on or off according to your specific needs.
    • Speed Limiting - while you can continue to gear limit your G Series trucks, Caterpillar offers speed limiting that allows the truck to travel at a more fuel efficient engine speed and gear selection.
    • Transmission Controls - New APECS transmission controls increase fuel efficiency by maintaining momentum and speed on grade.

    Performance

    Efficient application of power and technology

    Traction Control

    G Series introduces benefits to your fleet when running in wet conditions by introducing a more responsive traction controls system.

    • The system is steering sensitive to determine slip vs. high speed turns
    • The system engages at slower speeds returning traction sooner
    • The system engages sooner in the slip, potentially reducing tire wear
    • The system modulates instantly between the two wheel groups for control
    • Using the hydraulic service brakes facilitates the instant modulation and responsiveness

    The 777G will haul your material faster and more efficiently with increases in torque, new transmission controls and higher travel speeds.

    • A 7% increase in torque puts more power to the ground
    • New transmission controls carry more torque through the shifts, producing faster cycle times, most noticeably on grades
    • An increase in travel speed in 7th gear also helps generate faster cycle times
