Construction of four stations of a new type of assembly line of A320 aircraft. Compared to the previous system (aircraft shunting when mounted perpendicular to the longitudinal axis of the aircraft), the assembly line shift is now oriented in the direction of the longitudinal axis of the aircraft. At the same time, in order to speed up and streamline the assembly, larger subassemblies are used. The platforms are atypical in that the supporting columns of the fourth level platform pass through them.
