Rorest River Cardinal Towables – EU class O3 trailer with a 7,135 kg gross weight, 12.2 m length and roughly a 1,220 kg payload
With a gross weight of 7,135 kg the Cardinal Towables falls into EU trailer class O3, the band between 3.5 and 10 tonnes. Trailers of this size run air brakes rather than the simple overrun brake of the lighter classes and are pulled by medium-duty tractor units, often for the commercial haulage of vehicles, livestock or general cargo over longer distances.

The body measures 12.2 m in length and 2.55 m in width, with an unladen weight of 5,915 kg. That leaves a payload of 1,220 kg, low relative to the length and pointing to a heavy, reinforced body rather than bulk cargo. The 7.95 m wheelbase reflects a long, multi-axle layout of the kind needed for extended or bulky loads.
Class O3 requires an air-brake system with its own supply line from the towing vehicle, backed up by a parking brake for when the trailer is detached. The combination of great length and moderate gross weight points to cargo that is bulky rather than heavy, such as vehicles or livestock. Coupling type and nose weight of the tractor unit must match the trailer's hitch for the combination to be road-legal.
Buyers should check the brake system, including lines, actuators and linings on every axle, and inspect the suspension along the full length of the chassis. The main rails should be checked for sagging, corrosion and old weld repairs, the body for distortion and the condition of side panels or ramps. Tyres, lighting and the electrical connection to the tractor unit are worth checking too, along with a current roadworthiness certificate.
