AM 19 BC – three-axle EU class O4 heavy trailer with a 36,800 kg gross weight, 9,000 mm wheelbase and 23,000 kg payload for long, stable-shaped loads
With a gross weight of 36,800 kg, the AM 19 BC belongs to the heavy trailers of EU class O4, above ten tonnes. This class requires an independent air brake system and is intended for use behind suitably approved articulated or rigid tractor units in commercial long-haul work, not for private towing.

At a kerb weight of 13,800 kg, the payload comes to 23,000 kg, more than 60 per cent of the gross weight. The body length of 13,960 mm and width of 2,550 mm point to a long, narrow build typical of bulky but stable-shaped freight. Six wheels on a 9,000 mm wheelbase spread the weight over a long chassis and keep the loaded trailer stable even when cargo is unevenly distributed.
For trailers of this size, a category CE licence is the minimum requirement, and the air brake system must interface with the tractor unit through standardised coupling heads. The long wheelbase favours the transport of long components, pipes or precast parts, for which shorter trailers with a tight turning circle would be unsuitable.
When buying used, the frame deserves attention along its full length, especially the welds between the main beam and the three axle mounts. Brakes, air lines and the coupling heads to the tractor unit should be checked for leaks. With six wheels, comparing tyre wear across the axles is worthwhile, since uneven wear can point to a bent axle or a faulty suspension.

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.
