At a length of 12,600 mm, a width of 2,550 mm and a wheelbase of 9,380 mm, the UNS329 has an unladen weight of 8,670 kg; against the gross weight of 48,000 kg that leaves a payload of 39,330 kg. It runs on 12 wheels and is rated for 75 km/h. For a single model of this size, the ratio of unladen weight to payload shows how much the design is built around the load rather than its own structure.
In class O4, a compressed-air brake system across several axles is standard, and towing requires a category CE licence. How much the trailer can actually carry depends not only on gross weight but also on nose weight and coupling type, which determine the right towing vehicle.
When buying used, check the condition of axles and wheel bearings, the function of the braking system, corrosion on the frame and drawbar, and the state of lighting, the electrical connector, tyres and rims. Equally important are the load-securing anchor points and even wear of the brake linings across all axles. Exactly one example of this type is registered in the Netherlands, so spare parts are hard to find through normal trade.

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.
