Fire Engines Photos

Merikarvia 131 is Scania LS111 build 1978, now out of service. Pori 179 is Scania P380 build 2006 and Pomarkku 132 is Scania R113HL build 1988.
Althougt Pori 179 is not so high than other swap body tankers in Finland, someone firefighters dislike that appliance.

ArtoP, you have captured the classic Water Shuttle, or, Tanker Shuttle; the Tankers must be in line, to deliver their water to a Pumper.

Some serious water supply here - each Tanker must be carrying around 2500 Imperial Gallons(11,365 litres; 3,000 US Gals.) on their dual rear-axles.

I bet that the firemen were there, for a long time; the peat moss smoldering away underground would be difficult to extinguish fully.

Great shot of a rural operation.

This photo is taken second day when most of fire was extinguish. Tankers filled tractor tanks which went extinguish rest of fire. It was 20 kilometers circle which tankers drove.

First day was hurry, when didn't time to take photos. Then was very long lines from pumpers.

There is some difference between other fire departments in wildfire.
Some fire departments put one of tanker to be pumper, where others tankers supply their water.
Second option is use straigh "turnsupplycoupling" which have two inputs and one outlet. When first tanker is empty it's change valve so second tanker can supply own water without any break. And third option is pumper+"turnsupplycoupling"

I know that in US and Canada use that dump tank systems and it's faster than our system.

Sometimes here in the US, fire departments will use a "nurse tanker" system. This is somwhat like your second option. One fire department that I talked with had an 8000gal (30,400liter) tanker set up somewhat like picture #160. The tanker had a diesel powered single stage pump, 750gpm (2850lpm), located under the tank itself instead of at the rear. The tanker was set up with attack and supply hose. Normally the tanker responded behind the engines, with only 1/2 of its total capacity (15,200) to meet weight limitations on the road. On the scene then, the tanker was used in place of a portable pond. The tanker had 3 inputs. So, at any one time, more than one tanker, up to 3, could pump out their loads into the nurse tanker. The nurse tanker would then pump to an WrT, or to a Quint, or could be used to attack the fire itself. I've read that some departments have been able to maintain about 750gpm doing it this way.
