Design One of the main ROLT's activities is the vehicles of special purpose and special chassis design , as well as modernization of the chassis of different manufacturers. The car design is a complex of research and development and design-experimental works, which ultimate goal is the development of technical documentation of a new car. The concept of a new car is made up at the time of the major components and assemblies configuration. The correct configuration should ensure not only adherence to a given concept, but also the implementation of geometric, functional and legislative requirements for the car or special chassis. Requirements inherent in the concept are monitored at all stages of design: the concept phase, design, prototype model production, testing, production model manufacturing.
