Major updates to Caterpillar’s articulated truck range

Caterpillar has launched updated 725, 730, 730 EJ and 735 articulated trucks, with all interior functions now accessible through a sleek touchscreen, while a new engine powers the next generation of trucks with ratings from 257-316kW.

Designed to meet global emission standards, the C13 engine has a compact, lightweight design with no requirement for exhaust gas recirculation. Advanced automatic traction control prevents wheel slippage, while the new engine overspeed control works in tandem with automatic retarder control to manage braking and automatically adjust engine speed – meeting tough challenges head on.

The Cat 725, 730 and 735 models feature a redesigned dump body for easier loading than in previous designs. The redesigned body features a rerouted exhaust heat system that helps minimise material carry back, improving load efficiency and reducing cleanup time.

Updated 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 works in in parallel with stability assist, which prevents hoisting on uneven terrain. Configurable to material and jobsite conditions, this new feature monitors conditions to detect when the truck is experiencing high lateral acceleration, after which it provides a visual and audible alarm, reduces fuel and applies the service brake.

The new auto wait brake (AWB) automatically applies service brakes when the shift lever is in any position other than park and the truck stops. After a further eight seconds, the transmission shifts to neutral with AWB engaging.

Simply applying the throttle re-engages the transmission and releases the service brakes. This new feature eliminates the need to shift to park for short duration stops. Ther feature also works with hill assist by applying the service brakes, preventing rollback.

A new dump body height limit feature for the 725, 730 and 735 allows the bed raise height to be set to meet jobsite conditions. The operator can quickly 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.

The Cat 730 EJ ejects the load without raising the body to help maintain machine stability. This unique design allows load dispersal on inclines, side slopes and in very soft terrain.

Virtually eliminating material sticking to the body to increase productivity, the truck can eject in areas with low overhead clearance, such as around overhead lines or in tunnelling and underground operations. This versatility means the 730 EJ eject and spread material on the go to reduce the need for additional spreading and dozing equipment.

The Cat range trucks offer an optional object detect and multi-view camera via a separate secondary monitor. The system’s radar sensors, mounted fore and aft, provide visual and audible alerts when objects are within the truck’s travel path.

Another option is an optional interactive training tool called Operator Coaching, which measures and reports on individual operator behaviours across 14 separate activities. Tips can be viewed on a summary page on the main touchscreen display, while animated video tutorials provide operator instructions.

Production of the new next generation Cat articulated trucks, starting with the 730 model, is scheduled for January 2026. No word yet on Australian availability.
