T 4 40,0 by Myller Mittelta: EU class O4 trailer with a gross vehicle weight of 40,000 kg, a length of 12,200 mm and an unladen weight of 8,000 kg
With a gross vehicle weight of 40,000 kg, the T 4 40,0 sits in EU trailer class O4, the heavy trailers above 10 tonnes used in commercial long-haul transport behind heavy tractor units. Within that class, it ranks among the heavier builds, well above the 10-tonne threshold where O4 begins.

The trailer is 12,200 mm long and 2,550 mm wide, with an unladen weight of 8,000 kg and a payload of 32,000 kg, four times its own weight. Such a ratio is typical of trailers built for high payload rather than for a particularly low unladen weight, for example bulk goods or building materials moved on a regular basis.
O4 trailers are fitted with air brakes and a two-line connection, and the towing vehicle needs a matching brake system. The rig is driven on licence category CE, since the gross combination weight is far beyond the limits of the lighter categories. Towing vehicle and trailer must be treated and checked as one rig, including the coupling and the air supply.
With such a high payload share, it is worth checking the frame closely for signs of past overloading: bent chassis rails, worn-out axle mounts, and cracked welds at the cross members. Also check: condition of the brake linings, air suspension, tyre condition, the coupling and its mount, and confirm a valid roadworthiness inspection is on file.

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.
