Caterpillar is pleased to introduce to you the 773G Off-Highway Truck. You may be asking how, after 40 years of building trucks, Caterpillar has improved this product’s ability to support your business.
G Series has been designed and manufactured using the latest quality control technologies – virtual and hands on. This product has over 30,000 hours of proven performance in the hands of customers prior to production, all of which ensures the truck delivered to your yard is ready to work, reliably and dependably.
In addition to quality, Cat G Series trucks will lower your costs with seven different ways to help you conserve fuel. We offer you two customizable fuel economy modes that will let you choose your level of savings. With Cat G Series trucks in your haul fleet, you can be more productive, spend less time on maintenance, and support the environment with new levels of eco performance. Your crew will appreciate all the new comfort and conveniences in our updated cab. Simply put, Cat G Series trucks can and will make a positive difference to both your business and people – all day, every day.
The Cat C27 diesel engine is delivering 12% 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 Electronic Clutch Pressure Control (ECPC) 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 standstill and exceptionally smooth shift and ride quality.
A new Traction Control System (TCS) 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.
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.
G Series wheel spindles are solid steel and interchangeable from one side to the other, extending their useful service life.
For G Series, Caterpillar has inverted the rear suspension cylinders to better protect the rods, keeping them cleaner for longer durations.
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.
G Series trucks retain the highly productive and reliable Cat C27 diesel engine.
With new control strategies, this proven transmission is better than ever. Its new features include gear changes as smooth as an automobile and more torque through the shifts, getting the truck up to speed faster and negotiating grades quicker.
Caterpillar offers a simple and robust U.S. EPA Tier 4 and EU Stage V passive solution. Other than normal maintenance, this system requires no additional input or intervention by the operator.
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.
Located on top of the engine are two diesel oxidation catalysts (DOC), one for each exhaust outlet. These diesel oxidation catalysts reduce particulate emissions.
Caterpillar’s 10/10/20 Payload Policy is in place to help you maximize component life and the availability of your truck. Your Cat dealer can further explain the 10/10/20 Payload 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 target payload. Payloads in excess of 120% of target exceed the truck’s design parameters.
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.
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 773G 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.
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.
This program takes the payload value from Truck Production Management System, 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.
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.
A new optional fluid fill service center is located on the right front side of the machine. Technicians can check the level of all machine fluids including:
The fluid levels cannot be checked in the cab via the Advisor screen options menu. All the fluids are being monitored, but will only indicate to the operator when the level is below a safe operating level.
An Electrical Service Center is also at ground level located on the right front bumper of the machine.
G Series trucks will come equipped from the factory with a simple, time-saving brake wear indicator on the left rear wheel that provides technicians with a visible indicator for rear break wear levels.
Due to improved hydraulic system updates, which have made the system more efficient, Caterpillar is able to extend hydraulic filter life to 1,000 hours under normal operating conditions. All engine filters are conveniently grouped and easily accessible.
The 773G fuel tank is now larger (795 L or 210 gallons) to extend running time. The tank includes two new sight gauges that levels at ¼ full and ¾ full. Note that Tier 4/Stage V equipped machines require ultra-low sulfur diesel fuel and low ash engine oil.
An optional cab precleaner is available for air filters. This option can significantly extend your cab filter life and service intervals. Our field follow program machines saw significant benefits to filter life in the G Series machines.
The engine air inlet filters are conveniently located for secure, simple service.
