ENHANCED SITE SAFETY

ENHANCE SAFETY & PRODUCTIVITY

Lower dust levels, increase visibility, maintain haul road safety — know where and when to water
With automated water delivery, the operator can remain focused on traffic and driving
When water tank is full, the auto shutoff feature prevents overfilling and results in increased component life

COMFORTABLE CAB

OPERATOR COMFORT

Ergonomic, intuitive controls, with left side power window and automatic temperature control
Spacious cab with window area that supports visibility
Cab is isolation mounted reducing noise and vibration — sound suppression has decreased noise by 50%
Lighting packages illuminate both side and front of vehicle

OPTIMIZED PRODUCTIVITY

MEET YOUR PRODUCTION TARGETS

Properly watered haul roads directly impact fleet cycle times, enabling you to meet production targets.
Spend less time maintaining haul roads using proper watering techniques to solve overwatering and underwatering
Prevent damage to trucks and reduce unplanned downtime with properly watered haul roads

EFFICIENCY & SUSTAINABILITY

CONSERVE WATER. USE ONLY WHAT YOU NEED.

The Cat Water Delivery System (WDS) helps you manage water effectively and sustainability — helping you do more with less.
WDS utilizes automatic start and stop to help eliminate overwatering at road intersections.
WDS provides variable water flow based on truck speed, ensuring most efficient water placement.

DO MORE WITH LESS FUEL

Auto Neutral Idle: as the 777 idles in a forward gear, the transmission will automatically slip in and out of a neutral state to avoid stalling the torque converter and raising engine rpm.
Engine Idle Shutdown: when your truck is in park and idles for more than a preset time, the truck will initiate engine shutdown to conserve fuel. This feature can be time adjusted or turned on or off according to your specific needs.

SCALABLE CONNECTIVITY

CONNECT WITH CAT® MINESTAR™

Cat MineStar for water uses cloud-based connectivity through cellular and WiFi connection to collect and manage data at any job site.
We offer two levels of connectivity (Basic & Premium*) to meet any customer need using Cat MineStar.

INTEGRATION & SUPPORT

BACKED BY THE ONE YOU TRUST

Cat Water Solutions trucks are sold, serviced, and supported by the local Cat dealer you know and trust.
Full support of Cat dealer and parts network.
The truck is eligible for Equipment Protection Plans (EPP) & Customer Value Agreements (CVAs).

Type: Wet water pump/hydraulic motor coupling
Note: Operator selectable coverage: 0.2-0.8 L/m² (4 kph - 40 kph) / 0.5-0.2 gal/ft² (3 mph - 25 mph). Coverage rates above 0.6 L/m² may not be available at higher speeds depending on head count and configuration.
Note (1): Opening is automatically controlled by the system to achieve AutoMode Coverage or Manual Mode Flow Rate.
Note (2): AutoMode Spray controls water coverage automatically to the number of heads being used and ground speed achieved.
Note (3): Manual Mode allows the operator to set a water flow rate that is constant regardless of ground speed.

Note (1): Spray head opening is automatically controlled by the system to achieve Auto Mode Coverage or manual mode flow rate.
Note (2): The Auto Mode setting controls water coverage and automatically adjusts to the number of spray heads being used — independent of ground speed. This is an exclusive feature designed into the Cat WDS software to help water more efficiently. Water flow is co
Note (3): Alternatively, manual mode allows the operator to set a water flow rate that is constant regardless of ground speed. This mode is not recommended for daily operation and will reduce watering efficiency and may increase fuel usage.
Note (4): Spray heads on competitive water distribution systems require tools and maintenance to change flow and spray pattern. Caterpillar is the only company to have variable active spray heads to regulate water spray.
Note (5): Cannon performance depends on nozzle orifice and pipe size.
