Caterpillar is introducing the new Cat 775, the first in a new next-generation of off-highway haul trucks for the company. Distinguishing it from the previous 775 models, this 65tonne capacity hauler is engineered to enable fully autonomous capabilities in the future.
“The design of the Next Gen 775 represents a significant leap forward in off-highway truck technology, offering unmatched power, efficiency and safety features,” said Tony Fassino, group president of Caterpillar Construction Industries.
Caterpillar is leveraging its current Autonomous Hauling Systems (AHS), Cat MineStar Command for hauling, already at work at mine sites throughout the world, and scaling the system’s processes and technology to meet the specific needs of quarry operations.
“We are using the lessons learned from working with our US-based customer, Luck Stone, where we have MineStar Command for hauling installed on four Cat 777 trucks,” said Denise Johnson, group president of Caterpillar Resource Industries.
“The shift to the aggregate industry, where we are automating fewer trucks that don’t haul material 24 hours a day, is helping transform our technology and processes to manage smaller operations.”
The Cat 775 next-generation truck has a planned introduction in 2026. Autonomous capabilities with MineStar Command for hauling are currently under development, and a release date will be announced at a later date.
The 775 features an innovative new frame design that helps to optimise payload weight, a refined suspension for improved ride and handling, and advanced safety features like the 360° surround cameras and Cat Detect radar system for safety.
“Compared to previous models, our next-generation 775 off-highway truck features an industry-first frame design that reduces empty weight, delivering the potential for larger payloads and lower fuel burn. Plus, its 10% more body volume and improved turning radius helps to boost productivity and performance,” said David Holthaus, senior engineer and team lead for the Cat 775.
With more body volume, the truck’s new frame is optimised for weight distribution and structural efficiency. The new model uses nearly 30% less welding to minimise the risk of cracks and improve frame life. Less internal welding and ease of frame repairability help lower costs to maintain the new 775 over an estimated 40,000-hour truck life.
Its redesigned suspension boasts a lower centre of gravity. The 775 has shown to deliver better handling than previous designs, and an updated turning radius enhances on-site manoeuvrability. Improving service life, the truck experiences less bouncing on the tyres and driveline, and the operator feels less vibration and energy feedback into the truck.
The truck is powered by the 615kW Cat C27 engine and comes in different emissions configurations to meet different global regulations. The truck’s enhanced ride and handling allow for higher speeds on curves and driving in higher gears, which directly reduce fuel consumption during the cycle.
