Kroeger Rechterfeld SA25: an O4-class EU trailer with a 25,000 kg gross weight, 7,550 kg kerb weight, a length of 12.20 m and a 9.17 m wheelbase.
The name Kroeger Rechterfeld refers to the village of Rechterfeld in Lower Saxony, a place name that forms part of many German trailer makers' names alongside their surname. At a gross weight of 25,000 kg, the SA25 falls into the EU O4 trailer class, the heavy trailers above 10 tonnes that run long-haul routes behind heavy tractor units.

With a kerb weight of 7,550 kg and a length of 12.20 m, the trailer leaves a payload of 17,450 kg, close to seventy per cent of the gross weight. A 9.17 m wheelbase is a plausible, large figure for this length and points to two axle groups spaced well apart at either end of the vehicle. Its width of 2.50 m matches the European standard width.
As an O4-class vehicle, the SA25 needs an air brake system and is towed under a category CE licence. The figure 25 in the type designation SA25 matches the 25 tonnes of gross weight, a practice common among trailer makers who carry the weight class straight into the model name.
Buying a used long heavy trailer with widely spaced axles, it is worth checking the chassis in the middle section, which flexes most between the axle groups. It is also worth checking the air lines along the full length, the brake chambers at both axle groups, and the condition of the coupling and landing legs after decades of loading cycles.

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.
