In 1963 Caterpillar introduced the 769, a revolutionary off-road truck that was purpose-built for the rigors of mining and heavy construction. Fifty years later, our trucks have never been better. We’ve taken the best of our rugged, dependable heritage and combined it with technologies that help our environment, make your operators more productive, and dramatically improve the economics of your haul fleet. The 770G has an updated Traction Control System (TCS) to keep you moving even when the ground conditions aren’t perfect. You’ll see improvements in fuel use through new and flexible fuel savings and we're making the operating experience best in class with automotive quality shifting, noise reduction, and cab updates. Our heritage and new use of technology are combined in this truck for one purpose – the continued success of your business.
Our new G Series truck is equipped with a Cat C15 diesel engine. We recently celebrated 85 years in the engine business and the work we’ve put into these U.S. EPA Tier 4/EU Stage V engines is the culmination of that experience.
This C15 engine has been updated to meet global emission standards. Caterpillar equips every Tier 4/Stage V engine with industry leading electronic controls, fuel delivery, air processing, and aftertreatment. The results are an engine that conserves fuel, manages emissions, and facilitates greater diagnostics.
For this G Series truck, engine software modifications are allowing the truck to get more work done at lower speeds and at greater fuel economy. We’ve balanced this change with the addition of 7% more torque for putting a greater percentage of the power to the ground. With our new transmission controls working in tandem with the engine, this truck is delivering a significantly greater performance on grade and doing it more economically.
One additional and significant change for G Series is the 770G’s ability to work at full power in higher altitudes. This truck has a 23% increase in altitude capability, allowing it to climb to just short of 3000 meters or close to 10,000 feet without affecting performance.
Here are a few additional key features of the C15:
STANDARD ECONOMY MODE
G Series can adjust engine power based on your individual needs. Fuel savings are achieved by reducing power between 0.15 to 15 percent during all phases of operation.
ADAPTIVE ECONOMY MODE
New for G Series, this feature requires a customer-set baseline for production. Then, as the truck goes through the haul cycle and can hold a steady state, it constantly evaluates opportunities to reduce power and save fuel against your baseline. It's fully automatic with no special operation required.
AUTO NEUTRAL IDLE
As the 770G idles in a forward gear, such as waiting for the loader or crusher, the transmission will automatically slip into a neutral state that is more fuel efficient. As soon as the operator releases the brake or applies throttle, the truck shifts instantly back into the forward gear.
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.
In addition to the shift quality, fuel efficiency, and performance benefits of APECS, there are several key safety functions being performed by this technology:
Outstanding brake performance is an important differentiator for Cat trucks. The design principle is one of long-life and excellent performance in quarry, mine, and earthmoving applications.
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%.
Automatic Retarding Control is standard on the 770G. ARC electronically controls braking on grade to maintain the engine speed at approximately 2,200 rpm (adjustable from 1,950 to 2,200 rpm in increments of 10). ARC is deactivated when not in a retarding situation. This feature does the work of controlling truck speed on long downhill hauls without constant input from the operator; it’s smooth for greater control and provides faster cycle times over manual retarding. ARC will automatically engage to prevent engine overspeeding at any time during truck operation.
Caterpillar offers an optional engine brake. The Cat Engine compression brake works in conjunction with the ARC braking system to release pressure in selected cylinders to “brake” the machine during the compression stroke of the engine. By working in combination with ARC, the system reduces wear on brake components and allows the machine to travel up to 35% faster on downhill grades. This Caterpillar manufactured component is built for long, carefree service. It requires no tune-ups and no maintenance except periodic valve lash checks which are done as part of the routine engine maintenance. An on/off switch is located in the dash to disable the Cat compression brake.
TRACTION CONTROL
We’ve made significant updates to the performance capabilities of our Traction Control System. Our new system has:
TRUCK BODIES
The goal of our body designs is to provide rated payloads on each haul. Since no two jobsites are alike, we offer two body designs, optional sideboards for lightweight materials, and two liner options for the Flat Floor body to protect your investment and achieve the best possible wear life.
FLAT FLOOR AND DUAL SLOPE BODIES
Both of our body designs, with the exception of the Quarry body, are manufactured with base steel thicknesses of 16 mm (0.62 in) on the floor. This robust design can be augmented with an additional 16 mm (0.62 in) steel lining or a rubber liner option depending on your material type and jobsite conditions. When choosing a body type, consider the following:
Cat trucks are manufactured in Decatur, Illinois, where our facility has seen significant updates and is a flag ship for manufacturing at Caterpillar. Because reliability starts with clean parts, our assembly areas are in a dedicated building separate from fabricating. The assembly area is well-lit, clean, and contamination controlled. Our expert welders work on rotating platforms that provide ergonomic and thorough weld capability on our frames. All of our trucks are checked during design for ease of assembly, manufacture, and serviceability. We follow up with process and quality checks at each assembly station using the Andon system. Additional quality inspections are made at the end of the assembly line and at the dealership before it is delivered to you.
STRUCTURES
Our frames have 50 years of hard-core experience behind their design, but with new tools available, we are able to improve and validate our frames using the latest technology. One thing that hasn't changed is the frame's ability to handle the high stresses of being loaded and hauling at high speeds. We continue to strategically combine castings and box section construction to manage application forces.
A truck is only as productive as its operator. To that end, we have updated the 770G with some key features to help old and new operators be comfortable and confident while operating the truck.
COMFORT
VIMS
We’ve made our Vital Information Management System (VIMS) standard because it’s important. With VIMS on board you can access production data, machine health, and truck operation statistics. With this data you can make informed decisions on operator training, haul road efficiency, and scheduled service intervals. In addition, VIMS reports on event logging, idle time, and fuel use. VIMS information is available through the Advisor display inside the cab. Portals to connect and download the data are on the front bumper and inside the cab.
PATCH MATCH
Caterpillar can offer you loading tools that match your application and material types as well as your production requirements. Like the 770G, these machines are designed with important input from our customers and long hours of validation in the field. Whether your individual needs require a front shovel, an excavator or a wheel loader, Caterpillar has the model size, buckets, and ground engaging tools to help you load the 770G quickly and efficiently. The 770G can be reasonably pass matched with these Cat loading tools. The number of passes will be determined by bucket size and material density.
