Description

The invention relates to a vehicle arrangement for emergency or firefighting operations, in particular in the event of fires or accidents in difficult terrain. Vehicle configurations of the aforementioned type are generally known as fire engines. They are called out for assistance or firefighting operations, in case of fires, icy conditions, and in a wide variety of emergencies. Fires and other emergencies, such as accidents, can also occur in very inaccessible terrain. These can be forest fires or peat fires. Such terrain is inaccessible or unsafe for regular fire engines. If a forest fire in inaccessible terrain is still small and contained, extinguishing it directly on-site within the inaccessible area can be more effective than waiting on a forest road outside the forest and only attempting to extinguish the fire from the outside. The invention mentioned at the outset is therefore based on the objective of designing a vehicle arrangement in such a way that it is suitable for rough terrain and can effectively extinguish fires or provide assistance from there. This problem is solved according to the invention by designing the vehicle arrangement as a tractor with at least one tank trailer. The vehicle arrangement according to the invention consists of a combination of a tractor and at least one tank trailer. A tractor is ideally suited for driving and operating in rough terrain. It features very high ground clearance, all-wheel drive, a reduction gear, wide tires, and optionally, tires that can be further widened. This tractor can drive to a fire in difficult terrain, pulling the provided tank trailer. The tank trailer can then contain an extinguishing agent that can be applied on-site to extinguish the fire. A first further development of the invention provides that the tractor has at least one stable underbody protection plate. This allows it to move across rough terrain without damaging technical components in the underbody. The tractor can, for example, slide a short distance over a tree root; the advantage is that it can proceed across rough terrain. For use in the vicinity of fires, the tractor is designed to have a cab, particularly for the driver, with a positive pressure of > 10 mbar. The cab can be largely sealed. The positive pressure is maintained to prevent any fire-related air from entering the cab. Preferably, an air quality sensor is also installed in the cab, forming part of a self-contained air supply system. The air quality, carbon dioxide content, and similar parameters can be continuously measured by the air quality sensor. If certain limits are exceeded, oxygen cylinders and breathing masks can be used to restore the air quality, thus eliminating the need for an external air supply. A further embodiment of the invention is characterized in that the tractor is equipped with at least one extinguishing agent tank on its front linkage, and at least one extinguishing agent dispensing device is connected to the extinguishing agent tank. A tractor typically has a front linkage and a rear loading mechanism. Devices can be connected to these; according to this embodiment, an extinguishing agent tank is arranged on the front linkage. This extinguishing agent tank can hold extinguishing agents, which can be dispensed using the provided extinguishing agent dispensing device. The extinguishing agent delivery system is preferably designed as a monitor. The extinguishing agent tank on the front linkage and the monitor are located within the tractor driver's field of vision in the cab. The monitor can be controlled from the cab, allowing the tractor driver to target fires effectively. Alternatively, the extinguishing agent delivery system can be designed as piping on the outside of the tractor cab. In this case, the extinguishing agent is distributed around the cab, thus providing self-protection for the cab and its interior. As an alternative to a fire extinguishing agent tank, the tractor can be equipped with at least one hose reel on its front linkage. This reel can be designed to accommodate, for example, a 500-meter-long hose. The reel can have a hose drum mounted within the frame, to which at least one drive unit is assigned. Therefore, with this vehicle configuration, a fire extinguishing hose can first be unwound from the reel and laid over long distances, even into difficult terrain. According to a further development of the invention, the tank trailer belonging to the vehicle arrangement according to the invention has a drawbar for attaching it to the tractor, wherein a pump for transferring the tank contents or for filling the tank is arranged in the area of the drawbar. The pump is arranged in the area of the drawbar in a space-saving manner, which allows the tank of the tank trailer to be made correspondingly larger. The pump can function as a pressure and suction pump, so that it can discharge extinguishing agents from the tank or also fill the tank with liquid, for example in situatio
