Breunig BSA – EU class O4 trailer: 29,000 kg gross vehicle weight, 9,480 kg unladen weight, 13.80 m long, 2,600 mm wide, built 1998
With a gross vehicle weight of 29,000 kg, the Breunig BSA falls into EU trailer class O4, the heavy trailers and semi-trailers above 10 tonnes hauled in long-distance haulage with their own air brake system, whether behind a tractor unit or as a drawbar trailer. Vehicles of this size spread their weight across several axles and need a load-bearing chassis.

The Breunig BSA was built in 1998 and has an unladen weight of 9,480 kg; against a gross vehicle weight of 29,000 kg, that leaves a payload of 19,520 kg. Overall length is 13,800 mm, width 2,600 mm. The wheelbase is 9,050 mm. The permitted top speed is 100 km/h.
Trailers and semi-trailers in this weight class carry the actual load volume in road haulage, while the towing vehicle supplies only drive and steering. For the air brake to work at full effect, lines, brake cylinders and linings all have to work together without fault; without an intact brake coupling between towing vehicle and trailer, the combination may not be driven. The ratio of unladen weight to payload is within the usual range for this class.
When buying used, an air-braked trailer of this size lives or dies on the brake system: check lines, brake cylinders and linings for corrosion, leaks and wear. Inspect the chassis and frame for rust and cracks, along with axle bearings, suspension, tyres and tread depth, lighting, and the coupling to the towing vehicle. That also means checking the spare-parts supply for brakes and axles.
