The new Cat 777 (05) Water Solutions Truck provides an integrated solution to help reduce haul road dust by solving overwatering and underwatering issues. Built on the Cat 777E truck platform, the design integrates the truck, tank, and water delivery system, connected with technology. Its Cat Water Delivery System (WDS) combines with Cat MineStar Edge connectivity to help operations manage the site more safely and productively with flexible levels of technology to meet site needs.

Boasting a 75 700-l (20,000-gal) Cat-branded water tank, the 777 (05) comes complete with spray system, splash guards, fill chute and rock ejectors. It is powered by the 765 kW (1,026 hp) Cat C32B engine that meets China Nonroad Stage III emission standards, equivalent to U.S. EPA Tier 2.

The new water truck’s exclusive Cat WDS features a self-contained hydraulic system that controls spray patterns independent of engine RPM for consistent watering. Variable water flow, based on the truck’s speed, automatically starts and stops when the truck slows or comes to a halt, preventing overwatering and subsequent poor traction at road intersections. The pump features soft startups and automatically shuts off when the tank is empty to prevent system damage. 

Complete with auto shut-off to prevent overfilling, the water tank can be filled remotely, allowing the operator to remain inside the cab during the cycle to reduce potential operator slips and falls.
