Extinguishing arm

Together with Empl, the Austrian truck body manufacturer, Klaas developed a high-performance industrial firefighting vehicle with a telescopic, articulated arm made of high-quality aluminium. This can deliver 4,000 l of water a minute at a height of 25 m and can be operated from a safe distance. The multifunctional fire engine is predominantly used in chemical industrial parks or refineries for putting out large hostile fires or quelling clouds of dust.
