15、pin which is used for coupling semi-trailers to prime movers, taking into account the limitations of weight generally laid down by official requirements. NOTE - If, for extra heavy-duty vehicles, this coupling pin is not sufficient, an 90 89 mrn (3.5 in) fifth wheel coupling pin according to IS0 408
16、6 shall be used. In addition, this International Standard specifies the dimensional characteristics necessary for mounting and interchangeability. 2 Reference IS0 4086, Road vehicles - 90 semi-trailer fifth wheel coupling pin - Basic and mounting/interchangeability dimensions. 3 Basic functional dim
