Hose trolley (fire brigade)
As Schlauchwagen (short: SW ) are in Germany a number of vehicles of fire departments , and especially of civil protection called. As their name suggests, they are characterized by a load that consists almost exclusively of hose material . At the moment there is no longer a DIN standardized version of this vehicle. In Austria , the roughly equivalent vehicle is called a hose vehicle .
Areas of responsibility
The area of responsibility of the hose trolley is almost exclusively the pumping of extinguishing water over long distances , which is necessary in particular in the event of failure of the local hydrant network, in the event of a disaster or defense , forest fires or other major fires. The vehicle can also be used to support other fire brigade operations that require water pumping. In the future, these tasks are to be performed by the logistics equipment trolley and the SW KatS listed below.
Types
There are different designs of the hose trolley and its predecessor vehicles : In addition to the standardized vehicles listed below or vehicles introduced by the federal government or the federal states or similar, there is a multitude of different solutions with different hose lengths. As a rule, the number after "SW" indicates the length of the (B) pressure hoses carried . There are also special shapes on roll-off containers and with other hoses (for example F pressure hoses).
Hose truck
The hose truck ( SKW for short ) was the predecessor of the hose truck and was used by the air raid rescue service (and later also by fire services). The vehicle carried B pressure hoses with a total length of 1650 meters. It also had a portable fire pump as a fire extinguisher and a water jet pump for pumping water. A multi-purpose train , a collapsible container and a four-part extension ladder were also loaded onto the vehicle. Its crew consisted of a squadron .
Hose trolley 1000
The hose trolley 1000 (short: SW 1000 ) was the smaller design of the hose trolley. In some cases it was also built on an all-terrain Unimog chassis with a gross vehicle weight of 7.5 tons. The name-giving feature of the vehicle was the B-pressure hoses loaded in the rear of the vehicle with a total length of one kilometer. These hoses were housed in drawers when coupled together, so that they could be laid out while the vehicle was moving. Either a single line with a total length of 1000 meters or two lines at the same time, then with a length of 500 meters, could be laid out. This lay-out process was monitored by a fire brigade member who was on a step at the rear of the vehicle (if any). In addition, the hose trolley 1000 had a small load for fire fighting and a portable pump (very often loaded, but not according to the standard) as a fire pump. Its crew consisted of an independent squad . The standard for the SW 1000 has since been withdrawn.
Hose trolley 2000
The hose trolley 2000 (short: SW 2000 ) was the larger design of this vehicle. The vehicle was mainly delivered as a corner or round hood. More recent designs are rare, as it has been largely replaced by the 2000-Tr hose trolley . The hose trolley 2000 carried 2 kilometers of B pressure hoses, which were placed on drawers in bays and coupled so that they could be laid out during the journey. Two firefighters were able to stand on a platform at the rear of the vehicle and monitor the deployment process. In addition, numerous water-bearing fittings and a portable pump were loaded onto the vehicle . Its crew included a squadron .
Hose trolley 2000 with a crew
The hose trolley 2000 with troop crew (short: SW 2000-Tr ) is the most widespread form of the hose trolley because it was also procured by the federal government for extended disaster control. The four-wheel drive vehicle with a combined box and platform body could be operated by an independent squad . The eponymous 2000 meters of B pressure hoses were coupled together in hose baskets on the loading area so that they can be quickly laid out. In contrast to the SW 1000 and SW 2000, this requires the crew to follow the vehicle.
In addition, a portable pump with a delivery rate of 800 liters per minute at a nominal delivery pressure of 8 bar, a 5000 liter expansion tank and a small load for fire fighting (including two C-pressure hoses and a C-spray lance) were loaded onto the vehicle. The permissible total weight in the federal version was 9.5 tons in the case of the version on Unimog chassis and 9.6 tons in the series with chassis from IVECO-Magirus. In addition to the federal version, there was also a general standard for this type of vehicle in DIN 14565: 1991-03; In 2005, the standard was withdrawn in favor of the logistics equipment trolley (GW-L 2) with the additional loading module "water supply".
Hose trolleys for civil protection

Since the logistics equipment trolley does not meet the requirements of the federal government for its fire protection service, a separate hose trolley ( SW KatS for short ) was developed for civil protection and disaster control , but it is not standardized by DIN. It is the further development of the SW 2000-Tr, but has a portable pump with a nominal delivery rate of 1500 liters per minute at 10 bar nominal delivery pressure. He also carries 100 B pressure hoses of 20 meters each. In addition, there are 6 A suction hoses, 6 C pressure hoses, a C hollow jet pipe , a 5000 liter collapsible container and a chainsaw . Overall, the vehicle is specially designed for combined use with the new fire fighting group vehicle for disaster control (LF-KatS) . The first series of 16 vehicles was built by EMPL. The chassis is a Mercedes-Benz Atego 1326 AF from Daimler AG. The gross vehicle weight is 13.1 tons. Another series of 107 vehicles is being built by Freytag Karosseriebau GmbH & Co. KG on a MAN chassis.
