Ecocombi TD 18 – EU category O4 trailer with an 18,000 kg gross weight, 2,670 kg unladen weight, 15,330 kg payload, 5.78 m length and a 4.89 m axle spread
At a gross weight of 18,000 kg, the TD 18 belongs to EU trailer category O4, the band above 10 tonnes for which a compressed-air brake system is mandatory. At only 5.78 m, the TD 18 is a short vehicle compared with other trailers in this weight class.

At an unladen weight of 2,670 kg, the payload comes to 15,330 kg, more than five times the trailer's own weight, a ratio that points to a very light frame combined with correspondingly high load-bearing capacity. The 4.89 m axle spread takes up almost the entire length of the trailer, so the axle group sits close to both ends of the short frame. At 2.50 m width, the TD 18 sits within the European envelope for road vehicles.
Towing combinations in this weight class require a category CE licence. The combination of short length and high payload suits dense, compact goods where weight reaches the legal limit sooner than loading volume, such as bulk material or construction aggregate.
When buying used, the frame around the widely spaced axle mounts, the axle bearings and their suspension given the high payload, and the tightness of the air lines and couplings deserve particular attention. Because of the short build, the tyres should also be checked for even loading, and the coupling eye for wear given how much of the total weight it regularly carries.
