CS40T – EU class O4 lightweight trailer with a 31,500 kg gross weight, only 4,500 kg kerb weight and 27,000 kg payload at 12,500 mm length
With a gross weight of 31,500 kg, the CS40T belongs to the heavy trailers of EU class O4, above ten tonnes. Trailers in this class need an independent air brake system and are built for use behind suitably approved tractor units in commercial long-haul work.

Notable is the very low kerb weight of 4,500 kg, giving a payload of 27,000 kg – more than 85 per cent of the gross weight. At 12,500 mm long and 2,500 mm wide, this is a distinctly lightweight build, the kind found in frame designs engineered specifically for maximum payload, for example for containers or other light but bulky freight.
Driving such a combination requires at least a category CE licence. Such a high payload share of the gross weight calls for careful loading: axle loads must stay within permitted limits despite the low kerb weight, and uneven load distribution affects driving stability more on a lightweight frame than on a heavy one.
When buying used, given this lightweight ratio, frame inspection matters especially: cracks and fatigue on the main beams and cross-connections appear earlier on overloaded lightweight frames than on heavier constructions. The air brake system and axle suspension should be checked on a test rig, and the load-area locks deserve a function check, along with the floor covering, which on such a light frame is usually the first to show wear from repeated loading and unloading.

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.
