Cat® Water Delivery & Control System

A More Efficient Way to Manage Your Haul Roads
Whether your goal is dust control or haul road maintenance, theCat WDS is designed to put water to the ground in a controlled,intelligent way.
One of the advantages of our system is our independence
from engine speed. There are multiple advantages to thisindependence; fuel and water savings, spray pattern control, andan end to over watering.
Our system reduces water volume as ground speed is reduced –preventing overwatering at haul road intersections, at the startof grades or when traffic is encountered. When the truck speed
drops below 4.8 kph (3 mph), the system shuts off automatically toprevent overwatering.
The system has other conveniences. It has a spray head shutoff
button for on-coming traffic and an automatic shutoff when
the tank is empty. Seven different automated spray pattern
preconfigurations, including intermittent spray patterns, allow
the operator to concentrate on more important safety issues liketraffic, personnel and road conditions.
Fuel savings come both from the extensive strategies available
on the 777G bare chassis configuration and the water system.
The 777G bare chassis configuration has two economy mode
selections plus auto-neutral idle, and speed limiting. The Water
Delivery System saves fuel by being independent of engine speed.

We don’t require high rpm to achieve water pressure. In fact, theoptional water cannon operates at full pressure as the truck idles.
In addition to fuel savings, the Cat WDS is simple and costeffective to maintain. It has self cleaning spray nozzles that
open wide to eject debris. The system will automatically shutoff
when the water tank is empty to avoid pump seal failures, andtroubleshooting is made simple by self diagnostics displayed inthe cab.
Water conservation is achieved through the constant, flat
controlled spray pattern that delivers optimal liters per square
meter (gallons per square yard) and automatically shuts off below
3 mph. In addition, you’ll lose less spray to wind and evaporation
as the system produces larger, heavier water droplets designed toreach the ground.
The Cat WDS is simple to operate. The factory-built cab includes
a display and joystick for cannon operation. With the help ofoptional cameras, the operator can stay in the cab to position thetruck under the fill spout when it’s time to refill, and remote tankcontrols can automate this process even further.
The system can be customized to meet your specific site needs
and is available as an option from the factory on new 777G OffHighway Truck Bare Chassis. For more information on this highly
efficient water delivery system from Caterpillar, please contact
