Ja Trailer KPV 003 – EU category O4 heavy-load trailer: 60,000 kg gross weight, 51,690 kg payload, 16.91 m length, 2.55 m width, built 2022.
With a gross weight of 60,000 kg, the Ja Trailer KPV 003 sits far above the 10-tonne threshold of the EU trailer category O4, in the segment of heavy-load trailers for special transport. Trailers of this size run exclusively in commercial heavy haulage and, depending on the country, require separate permits for the road and route.

With an unladen weight of 8,310 kg, the payload comes to 51,690 kg, more than six times its own weight, a ratio that points to a lightweight frame built for maximum load. At 16.91 m long and 2.55 m wide, the KPV 003 is a long trailer within its class, built for bulky or particularly heavy single loads.
Heavy-load trailers of this size run an air brake system across several axle groups and usually air suspension, which spreads the axle load evenly at such a high gross weight. Towing in a combination requires licence category CE in the EU, plus a special permit for abnormal transport where standard dimensions or weights are exceeded.
When buying such a long and heavy used trailer, check all axle groups for even wheel-load distribution under load, the air suspension bellows for cracks, and the brake system for even action along the full length. The frame deserves particular attention for twisting and cracking, especially in the middle section between the axle groups, given the high payload.
