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 the water tank is full, the auto shutoff feature prevents overfilling and results in increased component life
— Monitor tank fill from inside the cab
— The water delivery system features automatic start and stop, based on truck speed, which eliminates overwatering at road intersections to improve safety for all vehicles on site
— New Traction Control System (TCS) and Wet Disc Braking is standard on all four corners of the truck
— Automatic Retarding Control (ARC) for downhill grades

OPERATOR COMFORT

— Easy, low-effort access to the cab
— Ergonomic, intuitive controls, with left side power window and automatic temperature control
— Spacious cab with window area that supports visibility
— Integrated footrest provides comfort and support
— Cab is isolation mounted reducing noise and vibration — sound suppression has decreased noise by 50%
— Lighting packages illuminate both to the side and front of the vehicle
— Factory-installed, integrated and durable ergonomic cab water controls are user-friendly and easy to learn

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
— Pump features soft startup and shuts off automatically when the tank is empty, eliminating damage and preventing the pump from running dry
— The 777 is faster and more efficient with a 7% increase in torque for more power to the ground, new transmission controls, and higher travel speeds.

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
— The water cannon operates while truck is idling, reducing fuel consumption by up to 50%

The 777 introduces several key fuel conservation features:
— 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.
— Speed Limiting: while you can continue to gear limit your trucks, Caterpillar offers speed limiting that allows the truck to travel at a more fuel efficient engine speed and gear selection.
— New APECS transmission controls increase fuel efficiency by maintaining momentum and speed on grade.

WATER DELIVERY SYSTEM:
The water cannon operates at idle, which reduces fuel consumption during cannon operation by up to 50%.

BACKED BY THE ONE YOU TRUST

Cat Water Solutions trucks are sold, serviced & supported by the local Cat dealer you know and trust.
— Full support of Cat dealer and parts network
— Cat dealer installation & retrofit kits available

  • BASIC CONNECTIVITY: EDGE EQUIPMENT TRACKING

    Customer need: "I need to know where my truck is and how much water it's distributing."

    Basic Connectivity automates basic data collection, eliminating paper recording by the operator:
    — Real-time & historical reporting**
    — Truck location and utilization data (starts & stops / routes)
    — Fuel and water level
    — Whether or not the truck is spraying water
    — Water Delivery System utilization (auto vs. manual mode)

  • PREMIUM CONNECTIVITY: EDGE PRODUCTION RECORDING

    Customer need: "I need to know what my operators are doing and how much water I'm using."

    Premium Connectivity offers a comprehensive reporting package with data & reports that can help operators improve watering technique/efficiency
    — Water usage by truck/fill station
    — Volume of water put down over time and area covered
    — Rate of water being put down, water delivery system setting by location, truck, and conditions
    — Activity breakdown including time & distance (watering, not watering, stopped, etc.)
    — Real-time reporting to the operator on water coverage & need (route, heat map, decay map)**1

    *Basic connectivity package comes standard on all Cat Water Solutions trucks with a 6-month complimentary service-based offering for better data insights. **Based on equipment connectivity via WiFi or cellular data. 1 Feature to be included in future update.
