Pno 135L TRI: an EU class O4 trailer with a gross vehicle weight of 36,000 kg, an unladen weight of 15,480 kg, a length of 13,900 mm and a 9,100 mm wheelbase, built in 1988
The Pno 135L TRI falls into EU trailer class O4 with a gross vehicle weight of 36,000 kg. Trailers of this size are built for professional freight transport, usually paired with a specifically approved towing vehicle, and carry a substantial share of their payload independent of their own body weight.

The 1988 135L TRI has an unladen weight of 15,480 kg and, at a gross vehicle weight of 36,000 kg, reaches a payload of 20,520 kg. At 13,900 mm long, 2,540 mm wide and with a 9,100 mm wheelbase, it is a long, sturdy build for classic heavy haulage. Such a build suited classic heavy-haulage work across long distances on the roads of its time.
Above 10 tonnes of gross vehicle weight, a simple overrun brake is no longer permitted; class O4 trailers need an air brake system that works together with the towing vehicle's brakes. The towing vehicle and trailer must be matched to the combined train weight, and such a combination is driven with a category CE licence.
When buying this trailer secondhand, the condition of the frame and axle mountings comes first, since through-corrosion typically starts there. The brake system should be checked for tightness and even action, and the tyres for age cracking rather than tread depth alone. Missing or damaged lighting and underrun guard are common reasons such vehicles fail the roadworthiness test.

- Look at the floor, cover or body from the inside — rust does not show from outside.
