Specifies the classification, design, interchangeability dimensions with tolerances, finish and marking requirements for coupling bodies for 50mm towballs, intended for trailers and caravans up to 3.5t aggregate trailer mass, for use on public roads.

This Standard specifies requirements for coupling bodies for ball couplings suitable for use with 50 mm towballs complying with AS 4177.2, for trailers and caravans up to 3.5 t aggregate trailer mass, for use on public roads. The method of determining the static strength of a coupling body and its attachments to the trailer drawbar and towball is given in Appendix A and the dynamic strength is given in Appendix B.NOTES: 1 Towbars and towballs are specified in AS 4177.1 and AS 4177.2 respectively. 2 The requirements for off-road applications are beyond the scope of this Standard. 3 Three rating classes are specified in this Standard, i.e. Type 750 kg, Type 2000 kg, and Type 3500 kg.
