Mercedes-Benz Special Trucks presents a extreme off-road Unimog fire-fighting vehicle at the RETTmobil


At this year’s RETTmobil, Mercedes-Benz Special Trucks will be presenting a Unimog water tender at stand F16 in the outdoor area. With numerous off-road features, the vehicle is designed for operations in particularly difficult terrain, such as forest and vegetation fires or flood and rescue operations. Visitors can obtain advice on site about the Unimog and its wide range of applications for blue light organizations. Other Unimog-based emergency vehicles, such as one of the 26 Unimog U 5023 recently procured by the state of Hesse, will also be on display at RETTmobil. The annual trade fair for innovative solutions in the field of fire and rescue technology takes place from May 15-17 in Fulda.

Unimog U 5023 as a “TLF 3000” water tender with Rosenbauer body 

The all-terrain Unimog U 5023 offers a range of technical features that equip it for operations in rough terrain and especially for fighting forest fires. With its high ground clearance of 50 centimetres, the Unimog can drive over many obstacles even in extreme terrain and climb steep slopes thanks to the large ramp and slope angles. The combination of special off-road tires and an integrated tire pressure regulation system, which allows the tire pressure to be quickly adjusted while driving, ensures traction on various surfaces. The so-called fording capability of up to 1.2 meters as an optional extra allows the crew to drive through rivers or use their vehicle in flooded areas, for example. The Unimog is also equipped with heat protection on all operationally relevant lines, which increases the safety of the emergency services and the reliability of the vehicle in heat-intensive environments.

The Unimog U 5023 is equipped with a Rosenbauer superstructure that meets the requirements of a TLF 3000 in accordance with fire department standard DIN-14530-22. The tank holds 3,000 liters and the extinguishing agent is applied by means of a FPN 10-2000 centrifugal fire pump in accordance with DIN EN 1028. Larger pump capacities and additional spray bars can also be added at the customer’s request. Two equipment compartments on each side and an equipment compartment in the rear of the vehicle provide the necessary storage space. Folding, non-slip steps facilitate access to the equipment compartments, while the step lighting further increases the safety of the emergency crews at night. For operations in the dark, ambient lighting with around 5,000 lumens per meter is on board and other equipment such as a light mast can be added.

The welded aluminium frame of the Rosenbauer superstructure ensures high stability and low weight, while the best possible weight distribution between the front and rear axles and a low centre of gravity optimize the vehicle’s handling characteristics. With the superstructure, the slope angle at the rear is 42 degrees, which also allows driving in very demanding terrain with changing topography.

More Unimogs at the stand of our partners
