The VON1B dates from 2018 and has an unladen weight of only 2,280 kg; against the gross weight of 28,000 kg that leaves an exceptionally high payload of 25,720 kg. At a length of only 4,000 mm, a width of 2,550 mm and a wheelbase of 2,220 mm, this is a short, compact trailer. Such a low unladen weight combined with such a high gross weight and short length is typical of vehicles carrying very dense, concentrated loads on a small footprint rather than bulky goods. The permitted top speed is 80 km/h, below the 100 km/h usually seen on trailers.
In class O4, a multi-axle compressed-air brake system is mandatory, and towing requires driving licence category CE. The 80 km/h speed limit fits a design geared towards high axle loads on a small footprint rather than fast road travel.
When buying such a short, heavily loaded trailer used, check the condition of the frame and axle mounts, since the entire load concentrates on a small footprint and deformation appears there first. The compressed-air brake system with its lines and coupling heads, as well as the axles and axle bearings, belong on a test rig. Exactly one example of this type is registered in the Netherlands.
