Der AT: Eine beeindruckende Erfolgsgeschichte

In 1994, the first fire engine from the AT (Advanced Technology) series left the Rosenbauer plant in Leonding. Recently, the 5,000th AT was delivered to the Aldersbach fire department in Bavaria (Germany). Rosenbauer takes this anniversary as an opportunity to put the development and the latest generation of the AT into focus through a three-part series.

 

It is equally at home in the deserts of Qatar as on the edge of the Arctic in Greenland, in the far reaches of Mongolia or on the idyllic beaches of Trinidad and Tobago. The revolutionary concept of the AT municipal fire department vehicle has spread throughout the world since the delivery of the first vehicle - it has contributed on all continents, with the exception of Antarctica. Flexibility and variability allow for vehicles to be realized exactly according to customer preferences and the challenges of the mission area. This is not only relevant for the equipment and construction, but begins with the chassis: The AT was constructed to date on chassis from eight different manufacturers: From the Commander in America to the Kamaz in Russia, via MAN and Mercedes-Benz chassis in Europe, to name just a few examples.

Revolutionary design concept

The concept of a lightweight construction was a real revolution in the first   generation of the AT, and is still considered state-of-the-art today. The use of laser-cut aluminum sandwich panels brings considerable decisive advantages in comparison to previously conventional steel/skeleton constructions.   For one, it allows optimal utilization of the structural volume. Secondly, the lower weight enables a higher payload for the installation of larger-volume water/foam tanks and complex pumping systems, as well as the carrying off more equipment. The AT's sizeable superstructure openings facilitate easy equipment removal.

Continuous development

The first generation of AT was a great success, with over 900 vehicles delivered. The vehicle has been constantly developed, improved, and adapted to new challenges in firefighting. The second generation seamlessly continued the success of the first, with more than 2,500 vehicles coming off the line by the end of production, and vehicles of the current third generation are also in high demand worldwide.

No. 5,000 - the anniversary AT

The reasons for the continued success of the AT for over 20 years is obvious with a glance at the rescue firefighting group vehicle 20 of the Aldersbach volunteer fire department. When purchasing, highest safety, ease of use, performance, and especially reliability were paramount to the decision. The choice fell on the AT from Rosenbauer. "Among other things, the functionality, the quality of workmanship, and after-sales service and supply of spare parts were crucial to the decision," said Christian Kirschner, deputy commander of the Aldersbach fire department .

Intuitive operation and perfect space utilization

The vehicle is built on a MAN 4x4 and is equipped with the latest and best Rosenbauer technology. For example, the lighting, generator, and pump are controlled via the LCS 2.0 (Logic Control System). The N35 normal pressure pump and the DIGIMATIC 42 pressure proportioning system can be easily operated via the display. In addition to the two pressure outlets, emergency crews can rely upon the rapid intervention system with a 50 m Formtex hose and an RM24M water-foam monitor during operation. Particular attention was paid to the clear arrangement of the equipment and its safe stowage and removal. The well-proven COMFORT support range ensures optimal use of the available storage space. 

 

With the new HLF 20, the Aldersbach fire department has an ultra-modern and perfectly equipped vehicle for many operational situations.
