Abstract: A fire-fighting device includes an extinguishing device arranged on an end region of a cantilever arm and is adjustable in at least one spatial direction. A penetration fixture is adjustable relative to the extinguishing device and has a double-acting pressure cylinder subjectable to pressure by a pressure medium from a hydraulic system via at least one control valve. The cylinder has a tubular continuous piston rod having a penetration tool on a protruding end having a through-hole and a nozzle head. At another end, the piston rod is connected in line with a supply mechanism for an extinguishing medium. Pressure accumulator elements are in fluid communication with a pressure chamber of the pressure cylinder for extending the penetration tool and with a return line for the pressure medium from another pressure chamber for retracting the penetration tool.
