such mark may be either a "type" mark enabling the rating to be obtained from the manufacturer's literature, or a "strength" mark stating the actual rating.

44.2.3.2.12.          Strength of 'Fifth Wheel' king pins
44.2.3.2.12.1.   The strength of 'Fifth Wheel' king
pins used in 'Road Trains' shall:

          44.2.3.2.12.1.1. be at least that required in Australian Standard 2175 -1978 Part 1 "Australian Standard Specification for 54 mm Fifth Wheel King Pins for Semi-trailers and Low Loaders";#

          44.2.3.2.12.1.2.  where the 'Gross Combination Mass' exceeds 75 tonnes, be certified by its manufacturer as being of adequate design and capacity to operate in 'Road Train' service at the 'Gross Combination Mass' nominated; and

          44.2.3.2.12.1.3. be marked on the king pin as the maximum 'Gross Combination Mass' for which the kingpin is suitable, the kingpin shall also marked with the manufacturer's name or trademark

44.2.3.2.12.2.   The installation of 'Fifth Wheel' king pins shall be certified as being in accordance with Australian Standard 2175 - 1978 provided that where the 'Gross Combination Mass' exceeds 75 tonnes, the strength of the installation shall be in accordance with Part 2 of that standard.#
44.2.3.2.12.3.   'Converter Dolly' Configuration
         'Converter Doilies' shall have a 'Single Axle' or 'Tandem Axle Group' and conform with the requirements of one of the Clauses 44.2.3.2.13.1 to 44.2.3.2.13.3.

          44.2.3.2.13.3.1. The 'Converter Dolly' shall be constructed so that the torque reaction generated in the dolly by braking forces shall be carried through the dolly's 'Fifth Wheel' assembly into the 'Semi-trailer' coupled to that 'Fifth Wheel' assembly and the 'Drawbar' shall be connected to the dolly chassis through a flexible coupling which allows the 'Drawbar' to pivot relative to the dolly chassis about a horizontal axis. Any 'Tandem Axle Group' supporting such a dolly shall have a non 'Brake Reactive Suspension' system.

          44.2.3.2.13.3.2. The 'Converter Dolly' shall be constructed so that the torque reaction is transmitted through a tow coupling designed for this purpose into the drawing vehicle and the 'Drawbar' and chassis shall be integral and the
          dolly's 'Fifth Wheel' assembly shall be able to pivot about a horizontal axis.  Any 'Tandem Axle Group' supporting such a dolly shall have a single pivot (suspension) system.

          44.2.3.2.13.3.3. The 'Convener Dolly' shall be constructed so that the torque reaction generated in the dolly by braking forces shall be carried through a limited travel suspension fitted to the 'Tandem Axle Group' fitted to the dolly. Such a dolly shall have a 'Drawbar' connected to the dolly chassis through a flexible coupling which allows the 'Drawbar' to pivot relative to the dolly chassis about a horizontal axis. The `Tandem Axle Group' supporting such a dolly shall have one of the following (suspension) systems:

           44.2.3.2.13.3.1. a system incorporating at least 4 laminated
