With an unladen weight of 7,900 kg, payload comes to roughly 20,100 kg. Length is 9.10 m and width 2.50 m, just under the 2.55 m maximum width allowed for road vehicles. For its age, the VPV-3-9.1 shows the compact but load-capable layout typical of a 1980s build.
Class O4 trailers run on compressed-air brakes, controlled through the towing vehicle's air line and applying automatically if the connection is severed. On a vehicle of this age, the brake system is usually simpler than on current trailers, without the electronic control systems common today.
When buying a trailer this old, the condition of the brake lines and cylinders, rust on load-bearing frame sections and the soundness of the axle suspension are the key checks. It is also worth confirming a current roadworthiness inspection and the availability of spare parts for the brake system before buying. A check of the number plate light and the earth connection at the plug rounds off the inspection, as these points corrode unnoticed. The tyre valves and the spare-wheel mount, where fitted, are worth a look too, since both are easy to overlook during a quick inspection.
