With a gross vehicle weight of 42,000 kg, the Vagnen belongs to EU trailer class O4, the heavy trailers and semi-trailers above 10 tonnes. That places it at the upper end of the weight range typical for long-haul transport, well above the 10-tonne threshold where O4 begins.

The Vagnen is 12,495 mm long and 2,550 mm wide, with an unladen weight of 6,900 kg. That gives a payload of 35,100 kg, more than five times its own weight, pointing to a particularly light frame built for bulky or light cargo rather than dense, heavy goods. At 12.5 m long, there is plenty of surface available for that kind of load.

For trailers in this weight class, air brakes with a two-line system are required. The rig is driven on licence category CE, since the gross combination weight is well beyond the limits of the lighter categories. The towing vehicle also needs an air supply and a coupling sized accordingly, matched to the trailer's own braking force.

With such a high ratio of payload to unladen weight, checking the frame closely for sagging and cracking at the cross members pays off, since lightly built structures react more sensitively to overloading than heavier frames built for dense goods. Also check: condition of the axle bearings, brake system, tyres, the coupling, and a valid roadworthiness inspection.
