Control Dust. Increase Visibility. Reduce Risk.

Cat® Water Solutions helps you efficiently reduce haul road dust to enhance safety and increase productivity at your job site, quarry, or mine. An integrated truck, tank, and water delivery system – connected with scalable levels of technology helps you solve overwatering and underwatering issues with a focus on sustainable operations. This innovative water solution is sold and supported by the local Cat dealer you know and trust.

Net Power advertised is the power available at the flywheel when
the engine is equipped with fan, air cleaner, muffler, and alternator
with engine speed at 1,800 rpm.

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.

Spray head opening is automatically controlled by the system to achieve Auto Mode Coverage or manual mode flow rate.

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.

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.

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.

Cannon performance depends on nozzle orifice and pipe size.

Multiple tank configurations are offered based on customer preference and regional locations. Water Tank Capacity Range: 110 000 - 121 133 L (29,059 - 32,000 gal)

Water Tank Capacity Range: 110 000 - 121 133 L (29,059 - 32,000 gal)

480,655 lb - 520,237 lb / 218 022 kg - 235 976 kg

241,647 lb - 251,098 lb / 109 610 kg - 113 896 kg

57,320 lb - 66,769 lb / 26 000 kg - 30 286 kg

Cat branded tanks include additional features and options commonly selected by customers in the industry. Splash guards, fill chute, and rock ejectors are standard.

Hoist cylinder mounting on all tank offerings enhances serviceability.

Operator selectable coverage: 0.2-0.8 L/m² (4 kph - 40 kph) / 0.5-0.2 gal/ft² (3 mph - 25 mph)

Maximum travel speeds with standard 33.00-R51 tires.

Productive capabilities of the 785D truck are such that, under certain job conditions, TKPH (TMPH) capabilities of standard or optional tires could be exceeded and, therefore, limit production.

Caterpillar recommends the customer evaluate all job conditions and consult the tire manufacturer for proper tire selection.

The ROPS (Rollover Protective Structure) for the cab offered by Caterpillar meets ISO 3471:2008 ROPS criteria.

The FOPS (Falling Objects Protective Structure) meets ISO 3449:2005 Level II FOPS criteria.

The operator sound exposure Leq (equivalent sound pressure level) measured according to work cycle procedures specified in ANSI/SAE J1166 MAY90 is 80 dB(A) for cab offered by Caterpillar, when properly installed, maintained and tested with doors and windows closed.

The exterior sound pressure level for the standard machine measured at a distance of 15 m (49 ft) according to the test procedures specified in SAE J88 APR95, mid-gear moving operation is 89 dB(A).

Hearing protection may be needed when operating with an open operator station and cab (when not properly maintained or doors/windows open) for extended periods or in a noisy environment.
