Coupling Caravan Trailer
Couplings on caravans and trailers perform the enormous task of pulling a variety of loads at highway speeds.
Australia is a caravaneer’s fantasy. There’s this beautiful feeling of comfortable isolation as you drive across wide open country, with no buildings, no people, and no pollution. The nights are as good as the days—perfect for lighting a bonfire and wistfully gazing at the stars.
The Australian outback is a great place to take an extended road trip. All you need is a grill, some food, lots of vegemite, a sturdy off-roader, and a trailer.
However, down under, a road trip isn’t really much of a ‘road’ trip. For the most part, you’ll be driving through dirt trails. You’ll also be driving through the rocky flatlands. This really just makes it all the more interesting.
Why You Need Spare Caravan/Trailer Couplings
It’s easy to forget that the land is harsh, though. Your favourite isolation—that is such a pleasure—could easily become your worst nightmare if planning isn’t foolproof.
If your caravan trailer parts break down, there’s no one you can call for help. And if you can’t fix whatever’s broken, you’ll have nowhere to get spare trailer parts from. In the sweltering Australian heat, it’s going to take a lot more than just time to fix your flat tire or broken trailer coupling by yourself.
There’s a surprisingly easy workaround, though.
Caravan Electric and Trailer Couplings at Couplemate
We deliver your spare trailer parts wherever you are, and faster than you can imagine. As a caravaneer, you’ve probably faced issues with your trailer couplings failing or getting damaged. We can get you the exact caravan and trailer couplings you need within 24 hours or less. And if we don’t have your kind of spare trailer coupling or parts like tow balls and dee shackles in stock, we’ll figure out a way to get one just for you within 48 hours.
All of the Couplemate manufactured trailer and truck pintle couplings are ADR-approved with Commonwealth Registration numbers. You maybe asked by Main Roads Inspections Officer for your Invoice containing the CRN of your coupling during the registration process.
Some Handy Expert Information On Couplings
At Couplemate, we stock couplings for caravans, trailers, and off-road campers, as well as couplings for horse floats. The type of coupling you require for your caravan is completely dependent upon the load you are carrying.
Box trailers and other small trailers used a star coupling for many years. Officials outlawed these after a string of serious issues. Occasionally, you’ll see one of these surface when they need a replacement. These trailers now use the standard 2000kg snap coupling, which does not use brakes.
The override coupling is used to control mechanical as well as hydraulic brakes, despite being rated at 2000kg as well. The snap coupling does not have this ability.
The best-seller—and the true workhorse of couplings—is the 3500kg Electric Coupling. This is installed on almost every caravan in Australia, as it incorporates a park brake handle for electric brakes, and it has a heavy rating of 3.5t.
Caravans and trailers rated between 3.5t and 4.5t use a larger 70mm ball and coupling. Unlike the couplings we’ve talked about already, you’ll need approval from DOT Canberra before you use the 70mm couplings on the highway.
Trailers rated over 4.5t must use a combination of air over hydraulic braking systems. Furthermore, we have an ADR-approved 6t ring coupling, which suits trailers rated up to 6t.
At Couplemate, our largest coupling is the 10t Gooseneck coupling. It is ADR-approved, and has all the necessary certification.
Couplemate sells quality trailer and caravan spares throughout Australia—covering the Northern Territory, Western Australia, South Australia, Victoria, New South Wales, and Queensland. We also ship products via Australia Post Air to New Zealand.

126.96.36.199. Up to 3.5 tonnes ‘ATM’ – Static Testing
188.8.131.52.1. Longitudinal tension and compression of minimum (N) 1.5 x 9.81 x ‘ATM’ (kg) for the ‘ATM’ at which the ‘Coupling’ is rated; and
184.108.40.206.2. Transverse thrust of minimum (N) 0.5 x 9.81 x ‘ATM’ (kg) for the ‘ATM’ at which the ‘Coupling’ is rated; and
220.127.116.11.3. Vertical tension and compression of minimum (N) 0.5 x 9.81 x ‘ATM’ (kg) for the ‘ATM’ at which the ‘Coupling’ is rated.
18.104.22.168. Up to 3.5 tonnes ‘ATM’ – Dynamic Testing
22.214.171.124.1. Horizontal alternating force of minimum +/- 12 kN acting in a line parallel to the ground and in the longitudinal median plane of the towing vehicle for at least 2 million cycles. The frequency is not to exceed 35 Hz, and must be chosen so as not to coincide with any natural frequency of the system.
12.3.3. Over 3.5 tonnes ‘ATM’
‘Couplings’ specifically designed for use between towing vehicles and trailers over 3.5 tonnes ‘ATM’ when installed in the design configuration must withstand the relevant ‘D-value’, or the relevant ‘D-value’ and ‘V-value’ dynamic forces nominated in clause 126.96.36.199 or clause 188.8.131.52 when these forces are applied separately at the intended ‘Coupling’ centreline, without incurring any residual deformation that would interfere with or degrade the function of the assembly or any breaks, cracks or separation of components.
184.108.40.206. Over 3.5 tonnes ‘ATM’ – ‘D-value’ rated Dynamic Testing
220.127.116.11.1. Horizontal alternating force of minimum (kN) +/- 0.6 x ‘Coupling’ ‘D-value’ (kN) acting in a line parallel to the ground and in the longitudinal median plane of the towing vehicle for at least 2 million cycles. The frequency is not to exceed 35 Hz, and must be chosen so as not to coincide with any natural frequency of the system.
18.104.22.168. Over 3.5 tonnes ‘ATM’ – ‘D-value’ and ‘V-value’ rated Dynamic Testing
22.214.171.124.1. Horizontal alternating force of minimum (kN) +/- 0.6 x ‘Coupling’ ‘D-value’ (kN) acting in a line parallel to the ground and in the longitudinal median plane of the towing vehicle and a vertical alternating force of minimum (kN) static vertical ‘Coupling’ load +/- (0.6 x ‘Coupling’ ‘V-value’ (kN)) acting vertically for at least 2 million cycles. The frequency is not to exceed 35 Hz, and must be chosen so as not to coincide with any natural frequency of the system.
The static vertical ‘Coupling’ load (kN) = 9.81 x S
where: S = ‘ATM’ – ‘GTM’ (tonnes).
