    Intelligent application of power and technology


    The Cat C27 ACERT diesel engine is delivering 5% additional power to the drive train. As a result, new and more robust drive train components, including a larger drive shaft and differential gears have been designed to handle the power.


    G Series introduces a new planetary powershift transmission control strategy called APECS. APECS takes the benefits of ECPC (Electronic Clutch Pressure Control) and adds part throttle shifting and torque shift management. The result is exceptionally smooth automotive-type shifting and ride quality. APECS also retains torque and momentum through the shifts; increasing performance on grades. The result is quick starts from a stand still and exceptionally smooth shift and ride quality.


    A new Traction Control System is now steering sensitive to differentiate between tire spin or high speed turns. The system now uses the hydraulically applied service brakes (vs. spring applied secondary brakes) allowing it to engage sooner and at lower speeds. G Series TCS modulates power and braking instantaneously between the two wheel groups, allowing a more appropriate response to ground conditions, and returning the truck to solid footing much sooner.

    Fuel Saving Strategies

    Solutions that support your lowest cost per ton

    Fuel Saving Strategies

    • Standard Economy Mode - G Series can adjust engine power based on your individual needs. With this feature, fuel savings are achieved by reducing power between 0.15 to 15 percent.
    • Adaptive Economy Mode - New for G Series - requires a baseline for production from you. As the truck goes through the haul cycle, it constantly evaluates your baseline against opportunities to reduce power and save fuel. It’s fully automatic with no special operation required.
    • Speed Limiting - while you can continue to gear limit your G Series trucks, Caterpillar offers another alternative you can utilize which is the new speed limiting feature. Speed limiting allows the truck to travel in its most fuel efficient gear.
    • Auto Neutral Idle - as the 775G waits for the loader or crusher while idling in a forward gear, the transmission will automatically slip into a neutral state to avoid stalling the torque converter and raising engine rpm. As soon as the operator releases the brake or applies throttle, the truck is instantly back in the forward gear.
    • Engine Idle Shutdown - when your G Series truck is in park and idles for more than a preset time which is set by the customer, 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.

    Structural Integrity

    Designed for years of off-road service


    Updated castings, improved bolted joints and a larger rear axle have matched the chassis design with the higher power ratings and performance specifications of the truck.

    New Brake Design

    G Series has increased the number of springs in its brake design. This increases the force available to disengage the brakes ensuring clearances are maintained, reducing wear. A new brake wear indicator can be found on the rear wheels to help you monitor brake life. Extending brake life can also be achieved by choosing the optional Cat Engine Brake. This Caterpillar design works in conjunction with the automatic retarder control (ARC) to slow the machine.

    Rear Wheel Steel Spindles

    G Series wheel spindles are solid steel and interchangeable from one side to the other extending their useful service life.

    Inverted Rear Cylinders

    For G Series, Caterpillar has inverted the rear suspension cylinders to better protect the rods, keeping them cleaner for longer durations.

    Emission Controls

    Major improvements for air quality using simple to use, reliable solutions

    Tier 4 Final Emission Controls

    Caterpillar offers a simple and robust U.S. EPA Tier 4 Final passive solution. Other than normal maintenance, this system requires no additional input or intervention by the operator.

    NOx Reduction

    Supported by cleaner burning, ultra-low sulfur diesel fuel and low ash oils, Caterpillar uses its engine-mounted NOx Reduction System (NRS) Technology to cool combustion chamber temperatures to control NOx production.

    PM Reduction

    Located on top of the engine are two diesel oxidation catalysts (DOC), one for each exhaust outlet. These diesel oxidation catalysts reduce particulate emissions. Tier 4 Final C27 ACERT engines are equipped with MEUI-C injectors. These injectors offer exceptional fuel atomization for engines running at slower speeds. MEUI-C injectors have an improved fuel shut off response time, saving fuel and reducing emissions. For customers purchasing trucks outside of North America, Caterpillar offers emission controls similar to those used for Tier 2/Stage II regulations.

    Machine Information and Monitoring

    Lowering your cost per ton with vital fleet information

    Truck Production Management System (TPMS)

    TPMS - Cat Truck Production Management System will help you get the best return on your truck investment by making sure you’re hauling appropriate payloads with every cycle.

    • Indicator side lights show the loader operator when they are on their last pass and when the truck is fully loaded
    • TPMS stores 2,400 payload cycles; reports on weights, haul cycle times, distances, with date and time stamps

    Instrument Cluster

    The instrument cluster is used primarily by the operator for quick and simple machine information at a glance. This display also warns the operator with solid lights (Category 1 Warnings) or flashing lights (Category 2 or 3 Warnings) as well as an audible alarm when an event is occurring.

    Cat Advisor Display

    The Advisor Display has five menus: 1. Operator: allows 10 people to set up individual profiles and preferences. 2. Monitor: displays four parameters per screen including Payload - there are three sections, Payload State; Payload and Target. Payload State - will display “Loading”; “Last Pass” or “Loaded.” Payload - displays the calculated payload weight, weight is taken twice to confirm. Target - displays the target payload. 3. Service: diagnostics including events, data logger, parameters, calibrations and more. 4. Settings: set specific targets for autolube intervals, speed limit and more. 5. Service Mode: a portal to password protected parameters.


    Vital Information Management System (VIMS™) is the hardware and software behind the machine information and payload tracking that comes through the Advisor display on your 775G truck. VIMS is standard, and like the Truck Production Management System, can greatly improve your ability to manage your fleet efficiency, machine production and provide operators with vital machine information.

    Ton Kilometer per Hour (TKPH), Ton Mile per Hour (TMPH) Tire Monitoring

    This program takes the payload value from TPMS, combines it with ambient air temperature, machine speed and the manufacturer’s TKPH (TMPH) rating for your tires and calculates tire condition continuously. As a tire approaches its temperature limits, the operator gets a warning inside the cab. This Caterpillar exclusive feature is an important tool in your efforts to extend tire life. NOTE: TKPH (TMPH) is a measure of the tire’s temperature limits to prevent reverse vulcanization of the tire and the associated damage.

    Cat Product Link

    Cat Product Link allows remote monitoring of equipment to improve overall fleet-management effectiveness. Product Link is deeply integrated into machine systems. Events and diagnostic codes, as well as hours, fuel, idle time and other detailed information are transmitted to a secure web based application, VisionLink™. VisionLink includes powerful tools to convey information to users and dealers, including mapping, working and idle time, fuel level and more. * Product Link licensing not available in all areas. Please consult your Cat dealer for availability.

    Your G Series truck has the ability to communicate (and receive) valuable information. Information that can lead you to producing at a lower cost per ton.
