4X4 version of the van based four ton Mercedes, with a front mounted pump rated at 800 LPM @ 10 AT. Widely used by German volunteers, these had no water tank but did accommodate a nine person crew. The front mounted pump was favored because it was an easy installation and increased the available space for equipment in the rear of the body. Germany has over twenty thousand volunteer fire companies, so in many cases their trucks are not deployed all that often. This explains why this example was in service for a full thirty years with the volunteers before spending another thirteen with a factory brigade. These light pumpers were most often built on Mercedes vans like this, but there were also examples of other makes, especially Opel.
This was assigned to one of the three volunteer fire stations in Leutenbach, a town of 11,000 with an active volunteer force of 120. These days the three stations have a total of three LF 10 pumpers, including one 4X4, a rescue truck, a tanker, a logistics truck, two squad trucks, a command van and a staff car. This year, up to the end of September, they responded to 24 incidents including five fires.
The LF10 replaced the old LF8 specification. The newer unit has a slightly more powerful pump ( usually rear mounted ), continues with a nine seat crew cab and adds a water tank. Although the DIN standard calls for a 600 litre tank, many fire services have ordered them with a bigger tank as 600 liters is considered too small to be really useful. Interesting that other fire services in Paris, Madrid, Berlin and several other places have also often upgraded pumpers with smaller water tanks in recent years to 900 to 1200 litres because the older units just could not supply an attack line for the time needed to set into a hydrant. BSPP specifically recommends 360 LPM, while Berlin sets the flow at 400 LPM, and both are looking at three minutes of autonomy before water is flowing from a hydrant. The corresponding US flow rate fir an initial interior attack line is usually 125 GPM, with four minutes supply from a 500 US gallon tank as a minimum. The old LF8 had no water tank, and - although often accompanied by a water tender or tanker - this did impact its ability to mount a rapid attack, despite having a large crew working to get water on the fire.
