Caterpillar reported the new 785D Water Truck, built on the 785D truck chassis, offers a smarter way to maintain haul roads while using less water.

Equipped with MineStar Edge connectivity and offering a water flowrate of up to 3,785 l/min., the unit features an integrated 121,133-l water tank, with spray system, splash guards, fill chute and rock ejectors. The spray system automatically controls the head opening to achieve AutoMode coverage or manual mode flow rate.

The Cat WDS is integrated into the 785D’s cab. It continually adjusts water flow during operation to achieve the desired coverage and flowrate, Caterpillar said. Featuring soft start-ups, the system’s water pump starts and stops automatically when the truck slows or stops to prevent overwatering and poor traction at intersections. The pump automatically turns off when the tank empties to prevent system damage from the pump running dry.

The 785D water truck is built to deliver durable performance in some of the toughest applications around the world, Caterpillar said. Units are fully supported by the extensive Cat dealer network. Retrofit kits are available for existing Cat 785D truck platforms.
