    TRANSMISSION

    The Cat planetary power shift transmission is an automatic, 7-speed transmission built for heavy-duty off road applications including those with long uphill grades. This transmission is managed with APECS, a strategy that provides an exceptionally smooth ride and allows power to carry through the shift points for excellent performance and speed on grades. In addition to delivering a quick and responsive truck, APECS is managing clutch pressures for long-life reliability. With its Cat power train components running in 7th gear, the 772G has a top speed of 79.7 km/h (49.5 mph).

    FUEL SAVING STRATEGIES

    Adjustable to meet your specific needs

    STANDARD ECONOMY MODE

    Standard fuel economy is switch activated from within the cab. This economy mode works by reducing engine power. Customers can adjust the savings by reducing the power output of the truck by 0.5 to 15 percent.

    ADAPTIVE ECONOMY MODE

    This economy mode uses on board sensors and electronics to find opportunities to reduce power based on steady state speed. Customers will set a productivity threshold that the truck should stay above. The truck will regulate the power level based on the haul profile and may change the power of the truck several times in one haul.

    AUTO NEUTRAL IDLE

    Auto Neutral Idle can have a measureable impact on fuel savings. It works by placing the truck in a neutral state if the operator has been idle in a forward gear with the brake or retarder applied. The truck will automatically resume the forward gear when the brake is released or the throttle is applied.

    ENGINE IDLE SHUTDOWN

    This feature must be activated by the customer. If engaged, the truck will warn the operator that it is about to shutdown after a prolonged period of idling in “Park”. Customers can set the idle time limit. When the time limit is reached, the truck will shut off the engine.

    SPEED LIMITING

    Speed limiting is a new feature for G Series trucks and is offered as an alternative to gear limiting. It offers customers both fuel saving and component wear benefits. Speed limiting allows the truck to find the most fuel efficient gear and engine speed while traveling at a set limit. Speed limiting will also work with Automatic Retarding Control.

    TRANSMISSION CONTROL STRATEGIES

    With its APECS transmission strategy, G Series trucks are carrying more torque and throttle through the shifts. The fuel benefit comes from recovering quickly during shifts and carrying more momentum up grades.

    BRAKE PERFORMANCE

    Confidence and control on grades

    An important differentiator for Cat trucks is their outstanding brake performance. The design principle is one of long life and excellent performance in quarry, mine and earthmoving applications.

    HYDRAULICALLY ACTUATED BRAKES

    Cat trucks are equipped with hydraulically actuated, rear brakes and caliper-disc front brakes. Each truck offers primary service brakes, hydraulic retarding and a parking brake. Two hydraulic accumulators provide the pressure required for the service brakes. The second accumulator acts as a back up. On the rear axle, the oil-cooled, multiple disc brakes have large discs that provide fade resistant performance. The parking brake is applied on the rear brakes and can hold the machine, with rated load, on a 15 percent slope. In turn, the service brakes are designed to hold the truck on slopes of 20 percent.

    AUTOMATIC RETARDING CONTROL (ARC)

    Automatic retarding control is standard on the 772G. This feature controls truck speed by automatically applying brake force when the engine exceeds a set rpm. Operators can adjust the engine speed between 1950 and 2200 rpm. This feature is important because it does the work of controlling truck speed on long downhill hauls without constant input from the operator; it’s smooth for greater control and has a tendency to provide faster cycle times over manual retarding. As a precautionary feature, ARC will automatically engage to prevent engine over speeding at any time during truck operation.

    CAT ENGINE BRAKE

    Caterpillar offers an optional engine brake. This engine brake works with ARC to control speed on grade. By incorporating engine braking with automatic retarding, customers can reduce brake component wear and achieve faster cycle times.

     

    TRACTION CONTROL SYSTEM

    Saving tire life, component wear and cycle times

    TRACTION CONTROL SYSTEM (TCS)

    If your ground conditions are wet or slippery, the 772G is equipped with Traction Control that engages quickly and effectively to control tires that are slipping. The system is steering sensitive to differentiate between turning or slipping, allowing the system to engage at slow speeds and much sooner in the slip. Once the system is engaged, it responds quickly by using the hydraulically applied service brakes, not the spring applied secondary brake. TCS regains traction faster by instantly modulating braking and power between the two rear wheel groups keeping your haul trucks moving and productive. By reacting quickly and at slow speeds, tire life and cycle times both benefit.

    TRUCK BODIES

    Bodies for your applications and material types.

    Caterpillar has body options to meet your material type and application needs. Cat truck bodies will last the life of the truck if properly configured, guarded and maintained.

    FLAT FLOOR AND DUAL SLOPE BODIES

    Flat floor and dual slope bodies are lined with 16 mm (0.62 in) of 400 Brinell Hardness Number (BNH) high-impact steel. Two floor types are available, flat and dual slope.

    Flat floor bodies are ideal for delivering product to a crusher; material unloads in a controlled manner.

    Dual slope bodies center the load and keep it stable and retained on steeper grades.

    STEEL LINER

    Caterpillar offers a single, 16 mm (0.62 in) steel liner that can be added to the flat floor and dual slope bodies to protect against high impact and highly abrasive materials.

    QUARRY BODY

    Caterpillar offers a purpose-built quarry body for soft limestone quarries. This body has a 25 mm (0.98 in), 400 BNH steel floor and does not require additional liners if kept in limestone.

    RUBBER LINER

    Customers who are loading extremely hard material that has high impact characteristics should consider a factory-installed rubber liner system. This system is intended for hard rock and should not be considered for machines that could be loaded with clay, cohesive material or hot material.

    10/10/20 PAYLOAD POLICY

    Cat bodies are equipped to retain high-capacity loads for long hauls and to travel up steep grades; however, overloading a truck can negatively impact productivity, reduce tire life and increase haul road maintenance costs. Caterpillar’s 10/10/20 Payload Guidelines are in place to help you maximize productivity with optimum component life and availability of your truck. Your Cat dealer can further explain the 10/10/20 policy. For optimum body life, Caterpillar recommends that 110% payloads occur no more than 10% of the time and that the average of all loads equal the nominal payload. Payload should never exceed 120% of nominal.

    STRUCTURES

    Long life and value

    FRAMES

    Cat trucks are known throughout the industry for reliable, long-life frames. Built for off-road maneuvering and haul road conditions, Caterpillar uses castings in high stress areas and box section construction to manage torsion-loading. Mild steel is used for its tensil strength and ease of welding, an important feature in being able to make field repairs. The frames are built on a platform that rotates 360 degrees, allowing consistent, deeply-penetrating welds. Each frame is subject to quality and conformance testing prior to assembly.

    SUSPENSION AND STEERING

    • The Cat suspension and steering design offers you the following benefits:
    • Excellent ride quality – empty or loaded
    • The front struts act as a king pin for long life in off-road applications
    • Nitrogen over oil strut design
    • Simple yet rugged steering system that maintains proper tire alignment
    • Inverted rear cylinders stay cleaner longer; reduce shock loading to the frame

    INFORMATION AND MONITORING

    Proactively manage your truck fleet

    CAT GAUGES AND ADVISOR SCREEN

    The Cat gauge cluster is a standard display found in the cab. It displays real-time machine performance and operating data. An optional Advisor display allows a greater degree of communication with the truck and from the truck.

    VIMS™

    VIMS is the Cat Vital Information Management System. This information management system is integrated into the engine, chassis and all other electronic controllers to deliver valuable information on machine health and productivity. This system uses the Advisor Display to communicate data. VIMS reports provide historgrams on truck operation, payloads and cycle times. These reports can help you manage your fleet, site and provide production levels.

    PRODUCT LINK

    Cat Product Link allows remote monitoring of equipment to improve overall fleet-management effectiveness. 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 our customers and their dealers, including mapping, working and idle time, fuel level and more. Product Link is not available in all areas, please check with your local Cat dealer.

    TRUCK PRODUCTION MANAGEMENT SYSTEM

    The Cat Truck Production Management System (TPMS) is an optional tool to help you manage your operations. Indicator lights on the truck tell the loader operator they have additional loads to put on the truck (solid green light) as well as one last pass (blinking red light) and then when the truck is loaded (solid red light). TPMS will track loads, cycle times and payload data – up to 2,400 cycles – and reports out through the on-board display or VIMS. The system takes two payload measurements; the first after loading and a second as the truck pulls away in 2nd gear. This is done for greater accuracy.

    TKPH/TMPH

    TKPH/TMPH stands for Ton Kilometer per Hour/Ton Mile per Hour. This optional feature is an on‑board tool that takes the manufacturer’s tire rating and in real time, compares it with ambient temperature, payload, and truck speed. If the tires are calculated to be approaching their temperature limits, the operator will receive a warning. If the tire temperature condition becomes critical your truck can be set up to automatically reduce (or limit) speed to allow cooling.
