Eksjövagnen FS 18-20 – heavy EU category O4 trailer with a 40,000 kg gross weight, 8,225 kg unladen weight, 31,775 kg payload, 12.57 m length and 2.60 m width
At a gross weight of 40,000 kg, the FS 18-20 counts among the heaviest members of EU trailer category O4, the trailers above 10 tonnes used in freight transport. This category requires a compressed-air brake system with load-dependent, multi-axle brake distribution.

At an unladen weight of 8,225 kg, the payload comes to 31,775 kg, nearly four times the trailer's own weight. At 12.57 m the FS 18-20 counts among the longer trailers in its category, spreading the high payload over a correspondingly large area. At 2.60 m width, the FS 18-20 slightly exceeds the general 2.55 m envelope for road vehicles.
Towing combinations in this weight class require a category CE licence. At a 40-tonne gross weight, road approval also depends on the number and spacing of the axles, since permitted axle loads are capped and the total weight has to be spread across several axles accordingly.
When buying used, given the high gross weight the axle bearings and spring elements on each axle deserve particular attention, along with the tightness of the air lines and couplings along the full length, the frame for cracking around the axle mounts, and even tyre wear. The coupling and its bearing are worth checking too, given the forces this weight class puts through it, along with the mudguards and marker lights along the long body.
