With a gross weight of 30,000 kg, the Hfm Trailers D22 falls into EU trailer class O4, the heavy trailers and semi-trailers above 10 tonnes. The company's English name, Trailers, states the vehicle type directly: a heavy-haulage trailer towed behind tractor units and heavy lorries.

With an unladen weight of 7,920 kg, payload comes to 22,080 kg, more than 70 per cent of the gross weight. At 2.55 m wide, the trailer is built to the standard width permitted for road traffic in the EU, allowing it to run in normal traffic without a special permit.
Trailers of this weight class are fitted with air brakes rather than the simple overrun brake used on light trailers. Towing it as a combination requires driving licence category C1E or CE in the EU, depending on the combined train weight. The favourable ratio of payload to unladen weight points to a chassis designed for weight saving, sought after in the competition for economical transport capacity.
When buying a used trailer of this kind, check the condition of the air brake system including lines and brake cylinders, rust on the frame and side members, the lighting, and the tyres and wheel bearings. On such a lightly built heavy-haulage chassis, it is also worth checking the frame joints for play and fatigue cracks after years of heavy-duty service, along with the towing coupling for wear.
