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.
