Caterpillar is rolling out its next gen 725, 730, 730 EJ and 735 articulated trucks, which the company says feature a smarter design.
The new ADTS are equipped with a suite of assisted and automatic features, including Auto Wait Brake function for added convenience and control during operation.
Production of the next generation Cat articulated trucks is scheduled for January 2026, starting with the 730 model.
The upgraded interior puts control at the operator’s fingertips, with all functions accessible through a sleek touchscreen or a smooth, responsive keypad. As well, the touchscreen can be effortlessly navigated using the integrated jog dial for added convenience. New push-to-start with operator ID stores up to 50 operator IDs to quickly get to work and safeguard against unauthorized use.
Cat C13 engine
The new Cat C13 engine powers the next gen trucks with ratings from 345 to 424 hp, depending on the model. Designed to meet global emission standards, the C13 features a compact, lightweight design with no need for exhaust gas recirculation. The machine is available in configurations suitable for all regions worldwide, ensuring reliable performance across a wide range of applications.
“Caterpillar’s latest machine design makes operating our next gen articulated trucks feel more comfortable, responsive, and user-friendly than ever,” said Sherrie Williams, Global Product Application specialist for Caterpillar. “With the introduction of the Cat C13B engine on the 725, the improved power-to-weight ratio means it is up to 14 per cent more efficient on our Tier 4 Final [and equivalent] machines.”
Automatic traction control
Requiring no operator input, advanced automatic traction control prevents wheel slippage in poor underfoot conditions for maximum traction and productivity. The new engine overspeed control works seamlessly with Automatic Retarder Control (ARC) to manage braking and automatically adjust engine speed—enhancing truck handling, improving steering response, and building confidence for newer operators in challenging conditions.
Machine speed limiting supports safe operation by allowing ground speed to be set by the operator or in service mode —I deal for uneven terrain, high-traffic areas or sites with strict speed regulations.
As well, the integrated body height limiter promotes safety by helping ensure the machine operates within jobsite standards and height restrictions.
The Cat 725, 730 and 735 ADTs feature a redesigned dump body that enables easier loading than previous designs and maximizes payload. The redesigned body features a rerouted exhaust heat system that helps minimize material carryback, improving load efficiency and reducing cleanup time.
The improved payload technology allows operators to view real-time load weights on the integrated display, and the system’s updated software and sensors provide accurate data. External payload indicator lights alert the loading operator when approaching rated payload and when payload is reached.
Rollover prevention
Cat’s Dynamic Roll Protection supports rollover prevention by working with the field-proven Stability Assist, which prevents hoisting on uneven terrain. Configurable to material and jobsite conditions, the new feature monitors conditions to detect if the truck is experiencing high lateral acceleration, provides a visual and audible alarm, reduces fuel and applies service brakes automatically. It reduces the risk of machine rollover due to high-speed cornering, helping minimize downtime and safety repairs from rolling the truck. As well, Stability Assist software reports information via VisionLink to increase awareness of when an event has occurred.
Auto Wait Brake
The new Auto Wait Brake (AWB) automatically applies service brakes when the shift lever is in any position other than park and ground speed reaches 0 km per hour. The service brakes apply in less than one second after the machine has stopped, and, after eight seconds, the transmission shifts to neutral with AWB engaging. Applying the throttle re-engages the transmission and releases the service brakes. This feature eliminates the need to shift to park for short duration stops and saves fuel when shifting to neutral. AWB also works with Hill Assist, by applying the service brakes and preventing rollback.
For 725, 730 and 735, a new dump body height limit feature allows the bed raise height to be set to meet jobsite conditions. The operator can set the raise height limit by raising the bed to the desired height and holding a button on the keypad. Alternatively, it can be set through the display service mode to meet site-wide limits. This feature helps prevent the dump body from contacting overhead objects and increases cycle time by limiting full-body travel.

The Cat 730 EJ ejects the load without raising the body to help maintain machine stability. The design allows load dispersal on inclines, side slopes and in very soft underfoot conditions like those found on landfill sites.
The truck can eject in areas with low overhead clearance, such as around overhead lines or in tunneling and underground operations, virtually eliminating material sticking to the body to increase productivity,
Delivering faster cycle times, the 730 EJ can eject and spread material on the go to reduce the need for additional spreading and dozing equipment.
Providing front and rear proximity detection, all next generation articulated trucks offer an optional object detect and multiview camera via a separate secondary monitor. The system’s radar sensors provide visual and audible alerts when objects are within the truck’s travel path.
For an enahcned view around the truck, four discrete camera views, which are configurable to the operator’s preference, are mounted at the front, rear and sides.
Coaching advice
An onboard, optional interactive training tool, Operator Coaching, measures and reports on individual operator behaviors that impact efficiency, safety and machine health. Operator Coaching identifies opportunities to improve operating behavior by monitoring 14 activities.
Operating tips can be viewed on a summary page on the main touchscreen display, while animated video tutorials provide operator instructions. For fleet managers, the GPS function includes maps to show the location of where tips are triggered on the work cycle.
