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

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

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%.

*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.

        
  • 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%.

Note
Operator selectable coverage: 0.1 - 0.8 L/m² (4 kph - 40 kph) / 0.05 - 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)
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 continually adjusted during operation to conserve water and achieve desired coverage and flow rate.
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.
