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
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
Traction Control System (TCS) and Wet Disc Braking is standard on all four corners of the truck
Automatic Retarding Control (ARC) for downhill grades

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
Factory-installed, integrated and durable ergonomic cab water controls are user-friendly and easy to learn

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
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.

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

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.
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%.

SCALABLE CONNECTIVITY

CONNECT WITH CAT® MINESTAR EDGE™

Cat MineStar Edge 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 Edge.
Water Solutions data can help ensure customers are meeting regulatory requirements.
Asset Management options include productivity, water usage, fuel & water tank levels, when & where to apply water, geofencing, asset location and remote management of water distribution.

BASIC CONNECTIVITY: EDGE EQUIPMENT TRACKING

"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

"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. ¹Feature to be included in future update.
