Sell SELL: two-axle trailer, built 2012, gross weight 18,000 kg, EU category O4, wheelbase 6,490 mm, payload 11,980 kg, for long load beds
Built in 2012 with a gross weight of 18,000 kg, the trailer SELL falls into EU category O4. Four wheels on a 6,490 mm wheelbase show two widely spaced axles rather than a tight axle group, a layout that gives a long, continuous load bed more stability than closely coupled axles.

At an overall length of 9,390 mm and a width of 2,550 mm, an unladen weight of 6,020 kg leaves a payload of 11,980 kg, almost two-thirds of the gross weight. The widely spaced wheelbase distributes the weight of the load more evenly across the bed than two closely set axles could.
Category O4 requires air brakes. A trailer this size is towed by vehicles holding driving licence category CE or C1E, depending on the combination's permitted gross weight. The long wheelbase improves cornering stability at low speed but requires a correspondingly wide turning circle from the towing vehicle.
Buying a two-axle trailer with this wheelbase used, the frame section between the axles matters most: sagging or cracking there only shows up after years of full loading. The brake lines running the long distance between the axles need checking for chafing, the bearings on both axles for play, and the tyres for even wear. The hitch and its frame mounting deserve separate attention too, since the long wheelbase transfers greater side forces into it while manoeuvring.
