Couplings

Trailer and Caravan Road Coupling Parts

Trailer couplings installed on caravans carry the enormous task of pulling various heavy loads at highway speeds. The towing vehicle varies from a light car to an SUV or a truck.

At Couplemate, we stock Al-ko couplings for road caravans, horse floats and off-road campers.

The type of trailer coupling required is entirely dependent upon the load or total weight of the trailer, and it may also depend on the weight of the tow vehicle.

Caravan mechanical and hydraulic brakes control the 2t override coupling.

The best-selling and real workhorse of the caravan industry is the 3500kg Electric Coupling.

Caravans and trailer towing equipment are rated to 3.5t tow ball. However, 4.5t trailer couplings use a 70mm tow ball. Unlike the caravan couplings we’ve discussed, you’ll need approval from DOT Canberra before you use the 70mm couplings on the highway.

Some caravan setups are unsuitable for a ball and coupling. These setups require a pintle and ring-type setup.

Trailers and towed vehicles rated over 4.5t use a combination of air-over hydraulic and heavy-duty braking systems.

Furthermore, we have an ADR-approved 6t ring coupling, which suits trailers rated up to 6t.
