  • the in the upper part of the trailer Coupling housed actuation mechanism can therefore not be encapsulated to the desired extent, that is, protected from external influences, because in addition to the anyway required openings for the coupling bolt and the actuating shaft, an opening for the passage of the release lever must be provided.
