8×4 Dual Boom Water Tower Fire Truck, 5000 L Water
This 8×4 dual boom water tower fire truck carries a 5000 L water tank and a 1000 L foam tank on a Euro V engine chassis. Two telescopic boom sections carry the monitor above the fire floor. A crew can attack a high rise compartment from outside the collapse zone while the appliance stays on stable ground. The dual boom layout spreads the waterway load over two ladders.
The waterway is made entirely of non corrosive material. It leads through the center post in the turntable up into the working cage where the monitor is mounted. A telescopic water pipe runs along the side of the booms, supported and protected by flexible pressure hose at the knuckles. Relief valves in the pump house guard the line against over pressure.
A HALE 8FC single stage centrifugal pump delivers 170 L/S at 1.0 Mpa and 70 L/S at 1.5 Mpa through a DN200 intake and a DN150 outlet. A DARLEY FSB240-C automatic mixer proportions foam at 0.5 to 10 percent. The monitor adjusts from 950 to 4800 L/min at 0.55 MPa, throws water 60 m and foam 55 m, and elevates from 90 to -45 degrees.
Boom action runs from 0 to 88 degrees on the down telescopic section and 0 to 164 degrees on the combined boom. The turntable rotates 360 degrees without limit. Outriggers extend in 40 s or less and the boom reaches rated height with 90 degree rotation in 270 s or less. The tank is stainless steel with 4 mm bottom plate and 3 mm elsewhere, baffled both ways.

Where it fits
A fit for industrial fire brigades covering high rise, tank farm and chemical plant risk, where a second elevated waterway shortens the attack. The 5000 L water and 1000 L foam tanks support an initial attack before hydrant supply is established on scene.
