These Coupling rings are primarily used in applications where the tow vehicle is a heavy commercial truck. As the Australian Standard AS 4177 states the 50mm towball to have a maximum capacity of 3500 kg AT M (total loaded mass), ring couplings are used when higher loads are involved


When used in a commercial or defence department application, often a 75 mm ring type towing eye is requested.

Similar in function to ball type couplings (fixed and over ride ) but instead of the connection to the tow vehicle being a standard 50 mm ball, the connection is a 75 mm inside diameter ring and this attaches to a “pintle hook” fitted to the tow vehicle.
