How may depts still use pump and roll trucks ( not brush trucks ) ? We have two tankers and one engine that are pump and roll. We use them for structure fires and water supply as well as fighting brush fires. One tanker is 3000 gal and the other is 1200 gal. The engine is 1000 gal.
Hey capt. funny you should mention watering down road ways. Myself and another member were asked to take our tanker down to a new road that was being built because the some of the residents were complaining about the dust. so we proceeded to make lots of mud!
We worked pretty hard to develop and engine that can stand as a class A pumper and also pump and roll. We have need of pump and roll pretty often with roadside and pasture grass and brush fires. We ended up with a Rosenbauer pump that has a high pressure side that ties in nicely with the Waterous CAFS unit. It's on a 4wd Freightliner with a 1000 gallon tank and a front bumper mounted Sidewinder. Works pretty sweet, because we can hit a few switches in the cab and be laying down foam without getting out, and no one rides outside. The big truck does pretty well in the soft sandy pastures we frequent and the CAFS stretches the water very far. Stationary, it serves as a 1000 gpm/200scfm engine.
We don't just use it for grass fires either. We got a call for a gooseneck trailer load of round bales about 50% engaged and arrived right after our neighboring dept. While they were still pulling their preconnect, we stopped about 40 feet from the bumper of the pickup and kicked on the sidewinder, which has a reach of about 125 feet. Within a minute we had it well enough under control to disconnect the truck from the trailer and pull it away.
Same thing for car fires, because we can hit it quick and hard with some class A foam, and take out a lot of the heat and smoke before we even dismount the truck.
We are working to upgrade our fleet to all have the same capabilities, but with smaller mini-attack type trucks. With the declining number of volunteers and the added stress put on the remaining one, we just felt it was justifiable costwise to make our equipment work as smart as possible. So far its paid off. I will say i don't think it would be near as effective without the CAFS capability.
Of our 3 engine fleet, 2 are pump and roll 1 is 500gpm and the other is 750gpm. This is just the way it was till the middle 80’s when we went big water on a specifically designed structure fire truck. We will have a new pump and roll in December with a 1000gpm which according to our MFG is the largest pump you can get in this configuration.
