and productivity at mines and quarries, the water truck is one of the most important pieces of support equipment at the site. T e new Cat 777 (05) Water Solutions Truck provides an integrated solution to help reduce haul road dust by solving overwatering and underwatering issues. T e new 777 (05) is built on the Cat
P
777E truck platform, proven at mine, quarry and construction sites globally. An innovative truck that uses less water for controlling haul road dust, 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 fl exible 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, fi ll chute and rock ejectors. It is powered by the 765kW (1,026hp) Cat C32B engine that meets China Nonroad Stage III emission standards, equivalent to U.S. EPA Tier 2.
The truck can be monitored to know when and where it is spraying water
INTELLIGENT NEW WATER DELIVERY SYSTEM T e 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 fl ow, 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.

automatically shuts off when the tank is empty to prevent system damage. WDS components include a water cannon, oil cooler, variable displacement pump, hydraulic oil tank, electronic control boxes and hydraulic motor/water pump. Covering up to a 24m (80ft) wide road in a single pass, the system sprays at rates reaching 0.8 l/m2
(0.2 gal/ft2 ) at speeds
from 4 to 40kph (3 to 25mph). With its maximum 61m (200ft) spray distance, the truck’s water cannon off ers a maximum fl ow rate reaching 473 l/min (1,250gal/ min). Factory-installed, ergonomic water
controls are integrated into the truck’s design for convenient system operation. Its innovative automated water delivery feature enables the operator to remain focused on driving and site traffi c to enhance safety. Complete with auto shut-off to prevent overfi lling, the water tank is fi lled remotely, allowing the operator to remain inside the cab during the cycle to reduce potential operator slips and falls.
