CAT 789D Autonomous Water Truck for Dust Control

Caterpillar has launched the 789D Autonomous Water Truck (AWT), designed to integrate with the Cat Command autonomous haulage fleet to manage haul road dust. Built on the 789D mining truck chassis, the AWT incorporates the Cat Water Delivery System (WDS) and MineStar™ technology to optimize water distribution. The system adjusts water flow based on truck speed and conditions, aiming to reduce waste and improve efficiency while preventing overwatering and underwatering.

The autonomous operation of the 789D AWT allows for increased fleet utilization by minimizing delays related to shift changes and breaks. The system can automate water refilling, track water usage, and interact with other autonomous and staffed equipment on-site. Caterpillar says the truck’s automated water delivery supports site safety by reducing airborne dust and limiting worker exposure during refills. The design allows for switching between autonomous and staffed operation when needed.

“The integration of our autonomous technology and water delivery solutions provides mining customers with an effective tool for dust control. By combining MineStar technology with Cat Water Delivery Systems, the 789D AWT enables more efficient water usage and helps optimize mine operations.” said Corey Wurtzbacher, General Manager and Vice President, Technology and Global Sales Support, Caterpillar.
