Carrier 4 The connection construction (4) securely attaches the side skirt panel (3) to the trailer chassis (2) It constitutes the main carrier interface that ensures secure fastening. During normal road use, the aerodynamic side skirt system (1) works. It is located in this position. In this position, the side skirt panel (3) enters the lower part of the trailer. By directing the airflow, it reduces drag resistance, thereby saving fuel. It contributes to reducing consumption and carbon emissions. Side skirt panel (3) extends along the trailer chassis (2) and controls the aforementioned air flow. It consists of a body with a geometry that will guide it in this direction. When a trailer needs to be loaded onto train wagons as part of rail transport, The movement mechanism (5) is activated and the lateral 10 is connected via the articulated linkage (6).
