Kolding LP313: a three-axle EU class O4 trailer with a 26,000 kg gross weight, 9.90 m length and a widely spread 5.85 m axle span
With a gross weight of 26,000 kg, the LP313 falls into EU trailer class O4, the heavy trailers and semi-trailers registered above 10 tonnes. At 9.90 m long and 2.43 m wide, it is a mid-sized but sturdy build for this class, one that looks designed for sustained loads rather than brief peak loads.

At a kerb weight of 6,700 kg, the payload works out to 19,300 kg, almost three times the trailer's own weight. The six wheels are spread across three axles with a 5.85 m span between the first and last axle, which at an overall length of 9.90 m amounts to a widely spread three-axle group, distributing the heavy load evenly across the long vehicle base rather than onto a small footprint.
Class O4 requires compressed-air brakes, and the three widely spaced axles keep the load per wheel sufficiently low at this gross weight. A build like this suits building materials, machinery or bulk goods that can be spread across the whole load bed, rather than concentrated point loads in one spot.
When buying used with a three-axle group spread this wide, the alignment of the axles relative to each other matters most: uneven tyre wear points to a twisted frame or worn bearings. All brake cylinders and air lines along the three axles, and the frame between the first and last axle, should also be checked carefully.
