In no other industry are there so many variants and options, depending on the purpose, as in fire protection. There is virtually no standard crew cab. The cab should be compatible with the body for every commercial vehicle. The customer presented us with great challenges in order to increase quality standards and reduce costs through economies of scale. In addition, the so-called team cabs must meet the crash test standards according to ECE-R29-3. By developing a modular platform strategy in individual components and assemblies, we have managed to cover 37 cab variants with a common part strategy. This not only improved costs and quality, but also optimised throughput times and reduced delivery times.
