Fahtz Heinz Fahtz Edelsb. – O3-class trailer built in 1962: 9,950 kg gross weight, 7,100 kg unladen weight, 12.80 m length.
With a gross weight of 9,950 kg, the Heinz Fahtz Edelsb. sits in EU trailer class O3, just below the 10-tonne threshold that separates it from the heavy trailers. Built in 1962, it is one of the oldest vehicles in the register, from an era when trailers of this size were still built in small numbers, often for a specific purpose.

With an unladen weight of 7,100 kg, payload comes to only 2,850 kg, a comparatively low figure for the vehicle's size: the body itself accounts for a large share of the gross weight. At 12.80 m long and 2.55 m wide, the trailer counts among the longer vehicles in its class, with a 6.94 m wheelbase spreading that length across a correspondingly long chassis.
Class O3 trailers run on air brakes rather than the simple overrun brake of lighter trailers. For a vehicle from the early 1960s that means essentially simple, mechanically regulated braking technology with no electronic assistance. Towing it as a combination in the EU requires licence category C1E or CE.
On a chassis more than 60 years old, structural condition comes first: check the frame and main rails for rust perforation and earlier repair welds, the brake lines for material age and leaks, the axle bearings for play, and the lighting for updates to current standards. Given such a long service life, it is also worth checking for earlier modifications to the body.
