Features & Benefits
ENHANCED SITE SAFETY
- 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
- 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
- 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
- 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%.
*Results shown from Cat WDS cannon output. Testing was conducted at the Caterpillar Tucson Proving Ground with data captured from a production study. Results may vary.
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.
- The water cannon operates at idle, which reduces fuel consumption during cannon operation by up to *50%.
*Results shown from Cat WDS cannon output. Testing was conducted at the Caterpillar Tucson Proving Ground with data captured from a production study. Results may vary.
SCALABLE CONNECTIVITY
- 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.
- Water Solutions data can help ensure customers are meeting regulatory requirements.
- View maps and dashboards of your operation to see how much your trucks are watering, where they are located, how much fuel they are using, and more.
INTEGRATION & SUPPORT
- 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).
