At a kerb weight of 14,440 kg, the payload works out to just 5,560 kg – the kerb weight alone makes up more than two-thirds of the entire gross weight. This unusually high ratio of dead weight to payload points to a heavy, reinforced frame construction, the kind built to carry concentrated, point loads rather than bulky goods spread evenly across the bed. The axle spacing is 8.09 m, almost as long as the build itself, spreading that concentrated load along the frame.

Class O4 requires compressed-air brakes throughout. A high kerb weight against a comparatively low payload is not at all unusual on special trailers built for heavy, compact loads such as construction machinery, containers or steel parts, since the reinforced frame itself already takes up a substantial share of the permitted gross weight before any cargo is loaded.

When buying used with this kind of ratio between dead weight and payload, the frame reinforcement itself matters most: cracks in welded reinforcement plates and deformation around the axle mounts are typical wear points on this build. The air-brake system, its lines and cylinders, and the condition of the long axle span should also be checked thoroughly before purchase.
