Dbw DBW – EU class O4 trailer: 20,000 kg gross vehicle weight, 6,600 kg unladen weight, 10.26 m long, 2,530 mm wide, built 2008
The Dbw DBW reaches a gross vehicle weight of 20,000 kg and so belongs to EU trailer class O4, the heavy trailers and semi-trailers beyond 10 tonnes hauled in long-distance haulage with their own air brakes behind a tractor unit. Vehicles like this need a chassis that is load-bearing along its full length and spreads the load across several axles.

The DBW was built in 2008 and has an unladen weight of 6,600 kg; against a gross vehicle weight of 20,000 kg, that leaves a payload of 13,400 kg. Overall length is 10,260 mm, width 2,530 mm.
With payload making up close to two-thirds of the gross weight, the DBW is built for high loads at a moderate weight of its own. The air brake system has to work evenly along the full length of over ten metres so the vehicle comes to a safe stop under full load without skewing.
When buying used, an air-braked trailer of this length lives or dies on the brake system along its full length: check lines, brake cylinders and linings on every axle for corrosion, leaks and wear. Inspect the chassis and frame along their full length for rust and cracks, along with axle bearings, suspension, tyres and tread depth, lighting and the coupling to the towing vehicle. With a build year of 2008, also check the condition of the brake lines and axle mounts after many years in service.
