Piening SALONWAGEN: an EU class O4 trailer with a gross vehicle weight of 18,000 kg, an unladen weight of 14,790 kg, a length of 14,900 mm and an 8,000 mm wheelbase, built in 1980
The Piening SALONWAGEN, with a gross vehicle weight of 18,000 kg, belongs to EU class O4, the heavy trailers above 10 tonnes. Vehicles in this weight class serve heavy-duty and construction-site transport, long-distance haulage, and the carriage of dense, compact goods that pack a lot of mass into a small footprint.

The 1980 SALONWAGEN has an unladen weight of 14,790 kg and, at a gross vehicle weight of 18,000 kg, only 3,210 kg of payload. At 14,900 mm long, 2,750 mm wide and with an 8,000 mm wheelbase, it is a very long, heavy build whose own weight already accounts for most of the permitted gross weight.
At this weight class, the brake system works on compressed air rather than an overrun mechanism, as EU rules require above 10 tonnes of gross vehicle weight. Towing such a trailer behind a suitable towing vehicle requires a category CE licence, and both vehicles must be compatible in their braking systems.
When buying this trailer secondhand, the condition of the frame and axle mountings comes first, since through-corrosion typically starts there. The brake system should be checked for tightness and even action, and the tyres for age cracking rather than tread depth alone. Missing or damaged lighting and underrun guard are common reasons such vehicles fail the roadworthiness test.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
