Caterpillar’s new Cat 775 is the first next generation design of off-highway trucks for the company. Distinguishing it from the previous 775 models, the 65-tonne payload 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 already leveraging its current Autonomous Hauling Systems (AHS), Cat MineStar Command for hauling, at work at mine sites throughout the world, and scaling the system’s processes and technology to meet the specific needs for 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 Cat 775 next generation truck has a planned introduction in 2026. Autonomous capabilities with MineStar Command for hauling are currently under development.
The truck features an innovative new frame design that helps to optimize payload weight, a refined suspension for improved ride and handling, and advanced safety features like the 360-degree surround cameras and Cat Detect radar system to deliver superior performance and safer and more comfortable operation.
“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 per cent 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 775’s new frame is optimized for weight distribution and structural efficiency. Compared to the 775G series truck, there is nearly 30 per cent less welding to minimize the risk of cracks and improve frame life. Less internal welding and ease of frame repairability help lower costs to maintain the new truck over an estimated 40,000-hour lifespan.
Caterpillar also redesigned the suspension to deliver 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 tires and driveline, and the operator feels less vibration and energy feedback into the truck.
Cat C27 engine
The truck is powered by the 825-hp Cat C27 engine and comes in different emissions configurations to meet different global regulations.
The U.S. EPA Tier 4 Final/Stage V version offers better fuel efficiency than previous models, with advanced electronic powertrain controls that deliver faster cycles and reduced road maintenance. The truck’s enhanced ride and handling allow for higher speeds on curves and driving in higher gears, which directly reduces fuel consumption during the cycle.
The new cab is designed for efficiency and equipped with features to automate functions.
The large windows give the operator visibility to the work area and surroundings, while the automatic cab temperature controls and the Cat next generation deluxe seat help to improve operator comfort.
The 775 is also equipped with 360-degree surround cameras with object detection to alert operators to hazards within the immediate vicinity.
Cat Detect combines radar and the camera systems to automatically detect hazards within critical areas around the truck — primarily the front, rear and turning radius on each side.
The next generation of enhanced serviceability incorporates extended-interval filters with ground-level access, ground-level lockout features and a serviceable suspension. Its design is fire suppression ready to simplify system installation.
The ability to access and analyze accurate real-time data enables faster diagnostics and enhances the ability to predict and prevent machine failure.
New for the 775, remote flash and troubleshooting capabilities help to boost truck availability. Remote flash instantly provides access to the latest software updates and enables the updates to be scheduled and executed at a time that doesn’t interrupt the production schedule. Remote Troubleshoot enables the dealer to perform diagnostics remotely while the truck is still in operation.
