en.Wedoany.com Reported - Caterpillar launched a new generation of 725, 730, 730 EJ, and 735 articulated dump trucks (ADTs) in September 2025, integrating multiple behind-the-scenes technologies that allow operators to drive with minimal additional effort.
According to Scott Thomas, Caterpillar's articulated truck market expert, these machines are designed to require minimal operator intervention—simply get in and drive. Standard features include dynamic rollover protection, automatic waiting brake (AWB), and body height limit (for 725, 730, and 735), which automatically adjust engine fuel supply or apply braking to prevent rollovers and maintain braking after stopping. All machine functions are accessible via keyboard, touchscreen, or integrated jogdial, and the new one-button start system supports storing up to 50 operator IDs.
These ADTs are powered by a common Caterpillar C13B diesel engine, with rated power ranging from 345 to 424 horsepower. The new engine's overspeed control works in conjunction with the automatic retarder control system (ARC) to manage braking and automatically adjust engine speed, improving handling and steering response.
Regarding the body, the 725, 730, and 735 models have been redesigned to optimize loading efficiency and increase payload. The exhaust heating system has been reconfigured to reduce material carryback, enhancing loading efficiency and shortening cleaning time. The 730 EJ uses a push-out discharge method without raising the body, helping maintain machine stability in conditions such as slopes or soft ground.
Optional technologies include an object detection and multi-view camera system, as well as an operator assistance system. The latter incorporates 14 evaluation indicators that display prompts on the screen when operators perform improper actions (e.g., turning too fast, dumping while articulated), along with comparison videos of incorrect and correct operations. This data can be reported to the backend via the Vision Link system for operator training and improvement.
Additionally, the new ADTs feature ground-level refueling, eliminating the need for operators to climb ladders for refueling, further enhancing convenience. Equipment World provided an in-depth look at these new haulers at the ConExpo 2026 trade show.
