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.
