Each power train component is designed and manufactured by Caterpillar to work together as a system in the 770G.
STANDARD ECONOMY MODE
Standard fuel economy is switch activated by the operator from within the cab. The standard economy mode works by reducing engine power. Customers can change the power output of the truck by 0.5 to 15 percent to save fuel.
ADAPTIVE ECONOMY MODE
Adaptive 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 cycle.
AUTO NEUTRAL IDLE
Auto Neutral Idle can have a measurable 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. Speed limiting allows the truck to travel at an efficient engine speed (rpm) and gear selection. Speed limiting works with Automatic Retarding Control and offers fuel efficiency and component life benefits over gear limiting.
TRANSMISSION CONTROL STRATEGIES
G Series trucks deliver excellent torque and throttle through the shifts. These quick yet smooth shifts help maintain momentum on grades and help fuel efficiency.
An important feature of Cat trucks is their reliable, heavy-duty 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 type front brakes. Each truck has primary service brakes, retarding capability and a parking brake. Rear axle brakes are oil-cooled with large friction discs that provide fade resistant performance. The front axle has dry disc-type brakes. The parking brake is applied on the rear brakes and is designed to hold the fully loaded truck on grades up to 15%. 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 770G. 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 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. The engine brake works with ARC to control speed on grade. By incorporating engine braking with automatic retarding, customers can reduce brake component wear in addition to achieving faster cycle times.
TRACTION CONTROL
For wet or slippery ground conditions, the 770G can be equipped with optional Traction Control. This system engages quickly and effectively returns traction to the spinning wheel. The system has steering position sensors to differentiate between turning or slipping. With this ability, the truck can engage TCS at slow speeds and much sooner in the slip. The TCS system uses the hydraulically applied service brakes, this is also a contributor to its responsiveness. By reacting quickly and at slow speeds, tire life and cycle times both benefit.
CAT GAUGES AND ADVSOR 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 histograms 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 (TPMS)
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.
