Motor vehicle assembly line

A motor vehicle assembly line designed to assume different configurations to assemble different motor vehicle bodies;

• the assembly line comprising at least one operating branch of a fixed length, regardless of the chosen configuration;
• the operating branch comprising a number of platforms aligned with one another along a given travelling direction;
• and each platform being designed to receive a respective body, feed it in said travelling direction, and subject it to a succession of n assembly operations along said operating branch;
• each platform being designed to be coupled to at least one longitudinal extension to assume a total length of a platform, which depends on the length of the body to be carried, wherein the total length of the platform is configurable to be a minimum length equal to the length of the platform without said extension coupled to the platform, and a maximum length of the platform equal to the length of the platform with said extension coupled to the platform;
• the fixed length of the operating branch being equal to n times said maximum length of the platform;
• wherein the at least one longitudinal extension is designed to be removably mounted to the respective platform;
• and
• wherein each platform comprises a substantially rectangular first frame defined on top by a walk-on surface and fitted at its longitudinal ends with first connecting means;
• and each extension comprises a second frame of the same width as the first frame and fitted at one longitudinal end with second connecting means, the second connecting means cooperating with the first connecting means to connect the extension rigidly to the first frame.
