Sjökumla S 3Lv 30: heavy trailer, built 2001, gross weight 30,000 kg, EU category O4, unladen weight 5,450 kg, for heavy-haulage transport
With a gross weight of 30,000 kg, the S 3Lv 30, built in 2001, falls into EU category O4, the upper half of trailer weights permitted on ordinary roads. Vehicles of this size run in heavy-haulage transport behind semi-tractors or heavy truck combinations across long distances.

At a length of 11,070 mm and a width of 2,600 mm, an unladen weight of 5,450 kg leaves a payload of 24,550 kg, more than four times the vehicle's own weight. Such a ratio is only achievable with a frame designed for high axle loads, with correspondingly sized axles and brakes.
Category O4 requires air brakes. A trailer like this is towed by vehicles holding driving licence category CE, in practice semi-tractors with a matching towing capacity and coupling load. The 2,600 mm width slightly exceeds the European standard road measure of 2.55 m.
Buying such a heavy, older trailer used, the frame comes first: cracks at welds and cross-members at this axle load develop over the years through material fatigue. The air brake system needs checking for leaks and response time, the axle bearings for play, and the registration history for signs of replaced axles or brake systems. Recent service records are worth reviewing too, since regularly replaced brake pads at this gross weight are normal wear, not a sign of trouble.

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.
