Construction and conversion of small production series for special vehicles and official agency vehicles

Kleinserie von Polizeieinsatzwägen

The conversion of official agency vehicles and special vehicles requires comprehensive skills, including design, construction, development, and custom-made components right through to the assembly of complete vehicles. Bertrandt is an expert in the construction and conversion of small production series. For more than 15 years, we have been developing special vehicles from ‘batch size 1’ for the fire service, police, rescue services, and emergency doctors, and we convert more than 600 vehicles every year. The conversions are carried out independently of the vehicle manufacturer and are specially tailored to the requirements of the customer or to the specific areas of application.

Development and construction according to specific requirements

The challenges involved in constructing and converting the special vehicles that are on the road around the world in a camouflaged, armored, or civilian form are as varied as the vehicle models themselves. As an installation partner, we also manufacture special equipment, electronic components (e. g. cable harness production), and the corresponding software for small production series and ‘one-off’ items – including the necessary validation and testing. In doing so, we can make use of all the resources and development expertise of the Bertrandt Group. In addition, we cooperate with special installation partners.

Quality assurance and certified competence

Our quality management system with the corresponding quality assurance measures rounds off our range of services. It goes without saying that we fulfill all the relevant standards and are a certified partner to several vehicle manufacturers, including BMW, VW Commercial Vehicles and Stellantis.
