Caterpillar Inc. introduced the new Cat 775 off-highway truck at bauma 2025, unveiling the company’s first next generation design in its off-highway truck lineup.
The 71-ton payload machine signals the company’s future direction, with built-in capabilities designed to support fully autonomous operation.
The new 775 builds on Caterpillar’s experience in autonomous haulage, drawing from its existing Cat MineStar Command for hauling systems in operation at mine sites worldwide.
Caterpillar is adapting these systems to meet the needs of smaller-scale quarry and aggregate operations.
The company has already deployed semi-autonomous technology in partnership with Luck Stone, a U.S.-based aggregate producer.
The collaboration involves outfitting Cat 777 trucks with autonomy-enabling systems. Insights from that deployment are guiding the development of technologies for the construction and aggregates sectors.
Productivity and Performance
The Cat 775 features a newly engineered frame that reduces empty weight, contributing to increased payload capacity and fuel efficiency.
Compared to its predecessor, the updated design includes 10% more body volume, an improved turning radius and a refined suspension system that enhances ride quality and vehicle handling.
The redesigned frame includes 30% fewer welds, aiming to improve durability, reduce the risk of cracking, and lower maintenance costs. The truck’s structure is optimized for longer service life, with easier access for frame repairs and reduced downtime.
Powered by a 825-horsepower Cat C27 engine, the truck is available in multiple emissions configurations. The Tier 4 Final/Stage V version shown at bauma is engineered for better fuel economy and faster cycle times, aided by advanced powertrain controls.
Safety Enhancements
The next generation 775 truck includes 360-degree surround cameras, and the Cat Detect radar system for hazard detection. These technologies work together to alert operators to obstacles around the truck’s perimeter, particularly in blind spots.
The redesigned cab includes expanded window visibility, automatic climate control and a Cat deluxe seat for improved comfort. New safety-focused automation features within the cab aim to reduce operator fatigue and enhance efficiency.
Service and Maintenance
The 775’s updated design includes extended-interval filters, ground-level service access and simplified suspension maintenance. The truck is fire suppression ready, facilitating system installation without additional modifications.
New digital capabilities include remote software updates and diagnostics. Remote Flash allows for scheduled updates to minimize downtime, while Remote Troubleshoot enables dealers to perform diagnostics while the truck is still operating.
Looking Ahead
Caterpillar expects to introduce the next generation 775 in 2026. Autonomous features using MineStar Command are currently in development, with release timelines to be announced.
The company plans to continue adapting its mining automation systems for smaller-scale operations across the construction and aggregates industries.
