Caterpillar announced the fifth iteration of the Cat 777 Water Solutions Truck, built on the Cat 777E truck platform and featuring Cat MineStar Edge for machine monitoring. The solution uses less water for controlling haul road dust than the predecessor model.

With a 75,700-liter, Cat-branded water tank, the 777 comes complete with spray system, splash guards, fill chute, and rock ejectors. It is powered by the 765-kW Cat C32B engine that meets China Non-road Stage III emission standards, equivalent to U.S. EPA Tier 2.

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

Levels of MineStar Edge technology are integrated with the Cat WDS to collect and send machine data, allowing site supervisors to monitor the water truck. Asset management options include productivity, water usage, fuel and water tank levels, when and where to apply water, geofencing, asset location, and remote management of water distribution, Cat said.

Cat dealer installation of the integrated system is available, and retrofit kits for existing Cat 777E truck platforms in the field have planned availability in the future.
