Cat® 773F WTR, 777F WTR and 785D WTR Trucks for Water Distribution Applications
Caterpillar Inc. offers specialized chassis for the water truck market.
Caterpillar Inc. now offers specialized chassis for the water truck market to improve performance and customer satisfaction for this increasingly important market segment. The first Water Truck (WTR) models to be offered are the Cat® 773F WTR and 777F WTR Off-Highway Trucks and the 785D WTR Mining Truck.
The ROPS structure on WTR models is certified to the ISO 3471 Tractor rating. The corresponding off-highway and mining truck chassis for these specific models no longer carry the Tractor ROPS certification.
773F WTR and 777F WTR models are not to be used for tow tractor applications. Tow tractor configurations are not available direct from Caterpillar. Due to configuration and certification requirements, these are only available through OEMs.
The Cat dealer or end-user customer is responsible for purchasing the water tank from various tank manufacturers around the world and assembling onto the chassis. A table of suggested tank sizes by model is listed below:
Water Tank Size
Model L (gal)
773F WTR 45 400 – 49 200 (12,000 – 13,000)
777F WTR 68 100 – 75 700 (18,000 – 20,000)
785D WTR 113 --- 562 (30,000)
