Abstract: A service vehicle comprises a chassis frame, a driver's cab and two side walls defining an equipment compartment on the chassis frame. The equipment compartment comprises equipment modules mounted in the range of each one of the side walls and holding service equipment, and the equipment modules may be guidingly displaced with respect to the vehicle for ready access thereto.

Abstract: A chassis frame particularly suitable for fire service vehicles comprises a pair of main bearers extending longitudinally and spaced transversely of the vehicles, each including at least one angled portion suitably disposed between the front and rear axles and enclosing an obtuse angle of less than 180.degree. towards the wheels. Engine mounting means are situated rearwardly of the front axle and an engine output shaft is positioned above the axle and between the axles and upper portions of the wheels. This facilitates adaptation to different service vehicle requirements, the installation of drive transmissions and service equipment such as fire fighting equipment whilst allowing for ease of access and flexibility in use.

Abstract: The invention relates to a method and a device for producing and dispensing extinguishing fluids mixed with adjuvants. The adjuvants are drawn in by suction in a metered manner and fed to a suction or intake pipe of an extinguishing fluid pump. A partial volume of the extinguishing fluid proportional to the quantity of extinguishing fluid conveyed in the delivery pipe is withdrawn from the delivery pipe. A negative pressure is generated thereby, by means of which the adjuvant is drawn in by suction and mixed with the extinguishing fluid. The extinguishing fluid mixed with additive is then fed to the suction or intake pipe of the extinguishing fluid pump.
