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%.

*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.
