WISS has manufactured and delivered a heavy firefighting and rescue vehicle for rescue services of one of the European refinery and petrochemicals holding. The vehicle is built on 3-axis Mercedes-Benz Actros 3348 (6x6) chassis. Its engine of max. power 350 kW (476 hp) meets the Euro 5 exhaust emission standard. Power is transmitted via a 16-speed (16+2) mechanical, synchronized gearbox. The cab is a one-unit, 2-door, air-conditioned, 3-seat cab (1+2).
A firefighting superstructure is a self-supporting shell structure made entirely of GRP. It features 5 equipment lockers – two at each side and one at rear. Side lockers are closed with aluminium shutters and the rear one with a top-hinged GRP tailgate. Additionally, bottom side lockers have hatches tilted down. They are used as work platforms and provide access to equipment on the top shelves. Sensors installed in all lockers inform of lockers’ opening and control the internal LED lights.
A 4000 l water tank made of glass-reinforced plastics is installed mid-ship. Two foam tanks of 3800 and 200 l volume are integrated with a water tank. In addition there are three CO2 cylinders (50 kg). Carbon dioxide is supplied via a 60 m rubber hose on an electric firefighting hose reel. A one-stage Ruberg R2-350 bronze pump of an output of 8000 l/min at 10 bar is located in the pump compartment at the rear part of a vehicle. The pump compartment is heated with a heating unit, which operates independently from the engine.
An electric water-foam monitor of an output of 6000 l/min is installed in the front part of the roof, which is also used as a work platform.
Furthermore, the chassis is equipped with a system of 4 spray nozzles - each with an output of 50-100 l/min. at 8 bar. Whereas work lights at the sides and at the back of a superstructure are switched on from the pump compartment. Moreover, a two-wheel hose reel cart with hose sections of 75 mm is transported on the left side of the back wall of a superstructure.
