Overview
Optimized Performance
Caterpillar is pleased to present the 773G Construction Truck. You may be wondering how, after 40 years of effort, Caterpillar has been able to further improve its support for your business?
The G series trucks have been designed and manufactured using the latest existing technologies, both in terms of software and hardware. Before being launched, this product has been tested for over 30,000 hours by customers to ensure that it is ready to operate, reliable, and robust.
In addition to its own qualities, Caterpillar's G series trucks will help you reduce your expenses by limiting fuel consumption in seven ways. We offer you two customizable fuel-saving modes to allow you to choose the desired level. By adding Caterpillar's G series trucks to your fleet, you will increase your productivity, spend less time on maintenance, and also work towards environmental sustainability thanks to the efficiency of these machines. Your staff will appreciate the comfort and all the new amenities of the redesigned cabin. In summary, Cat's G series trucks can and will make a difference day after day in your business and with your employees.

Performances - Power and technology at the service of intelligent products
Power The C27 Cat diesel engine provides 12% more power to the powertrain. To manage this power, new, more robust chain components have been installed, including a larger drive shaft and differential gears.
Fuel-saving strategies - Solutions ensuring a minimum cost per tonne
Fuel Saving Strategies Standard economy mode: G series machines are capable of adjusting the engine power according to your needs. This feature allows for fuel savings by reducing power from 0.15 to 15%. Adaptive economy mode: This new feature in the G series requires setting a production reference. Throughout its transport cycle, the dump truck constantly evaluates opportunities to reduce power and fuel consumption based on the references. Fully automated, this function does not require any specific intervention. Speed limitation: Although you can still limit the gears of the G series dump trucks, Caterpillar now allows you to use a new speed limitation feature. Speed limitation allows the dump truck to use the gear that offers the best energy efficiency. Automatic downshifting to neutral: When the 773G Dump Truck is waiting for a loader or crusher at idle with a forward speed, the transmission automatically shifts to neutral to prevent torque converter stalling and engine speed increase. As soon as the driver releases the brake or accelerates, the dump truck instantly returns to the original forward speed. Engine idle shutdown: When your G series dump truck is in a parked position and remains idle for longer than the customer-defined duration, the dump truck triggers an engine shutdown to save fuel. This feature can be adjusted, enabled, or disabled according to your specific needs.
Structural integrity - Machines designed for years of use on construction sites!
New Brake Model The number of springs used in the design of the brakes for the G series dump trucks has been increased. This allows both to increase the force available to release the brakes, to preserve the necessary clearances and therefore reduce wear. A new brake wear indicator placed on the rear wheels allows you to monitor the lifespan of the brakes. Steel Axles for Rear Wheels The solid steel wheel axles of the G series machines are interchangeable from one side to the other, which extends their useful service life. Inverted Rear Cylinders On all G series machines, Caterpillar has inverted the rear suspension cylinders to better protect the rods and keep them cleaner for longer. Structures Improved cast parts, reinforced bolted joints, and a larger rear axle allow the chassis design to be adapted to the rated powers and higher performance specifications of the dump truck.
Powertrain - Application-specific designs for unparalleled performance in the industry
Engine The G series dump trucks retain the Cat C27 diesel engine, which ensures high efficiency and reliability. Offering a 12% increase in power, the C27 delivers higher torque in service. Benefiting from the precision and responsiveness of Cat MEUI™ electronic injectors and controls, the C27 precisely controls fuel flow, emissions, and performance. The C27 is carefully balanced with vibration controls to reduce noise and limit excessive wear. The C27 is cooled by a variable speed fan or a conventional cooling fan. Powershift Transmission with Planetary Gears Thanks to its new control strategies, this proven transmission is more efficient than ever. Its new features include smooth gear changes like a car and increased torque during gear shifts, allowing the dump truck to accelerate faster and negotiate slopes more quickly.
Strategy adopted for bins on G-series models - Bins adapted to your applications and materials
Caterpillar allows you to easily choose the appropriate bucket based on your materials and specific tasks for your construction site.
Operating and monitoring machine information - Cost reduction through vital information for fleet management
Your G series dump truck has the ability to transmit (and receive) important information. In fact, this information can help you reduce your production cost per tonne.
Ease of maintenance - Clean, practical, and fast solutions
The G series dump trucks bring maintenance improvements that allow you to save time and simplify monitoring and maintaining machine fluid levels. They contribute to the cleanliness of your site and the reduction of maintenance costs associated with it.
