Lahrs TPA 10,5 / 6 2 E – O3-class drawbar trailer with 9,000 kg gross weight, 2,850 kg unladen weight and 8,040 mm length.
Between the ordinary car trailer and the semi-trailer sits the class of heavy drawbar trailers with a gross weight between 3.5 and 10 tonnes. They are pulled by a stand-alone lorry or a suitable tractor unit, carry no drive of their own, and add loading area to a combination without needing a second articulated unit.

The TPA 10,5 / 6 2 E carries a gross weight of 9,000 kg. Against an unladen weight of 2,850 kg that leaves a payload of 6,150 kg. Body length is 8,040 mm, width 2,520 mm – a ratio typical of a multi-axle trailer in the mid payload class for general haulage.
At 9,000 kg gross weight the TPA 10,5 / 6 2 E falls into EU trailer class O3, and so carries an air brake system from the factory rather than the simple overrun brake fitted to lighter trailers. Towing it requires at least driving licence category BE or C1E depending on the combined weight of the outfit.
When buying a used trailer in this weight class, check the air brake system: brake cylinders, lines and coupling heads should be free of corrosion, and leaks show up as pressure loss after parking. On the chassis, fatigue shows first on the cross members and at the axle mounting points; on the drawbar, check play in the towing eye and the operation of the jockey wheel, and look for uneven tyre wear that points to a bent axle.
