Self-build (Omavalmiste) PV

At 7,680 mm long and 2,550 mm wide, the PV 3500 has an unladen weight of 850 kg, giving a payload of around 2,650 kg. Such unusual length for the class combined with a low unladen weight points to a light, open build, the kind used for carrying bulky but not especially heavy loads.

Class O2 trailers can already be towed on a category B licence in many countries, provided the combined train weight stays under the local limit there. The overrun brake works purely mechanically, through the thrust generated as the towing vehicle brakes, with no power supply of its own, which makes servicing and inspection simpler than with an air brake system.

For a home-built trailer of this kind, it is worth inspecting the welds of the hand-built chassis closely, checking unprotected sections for rust, and examining the overrun coupling together with the brake linkage. The tyres, sized for this length of build, and the completeness of the lighting system also deserve a careful look, since amateur builds often have outstanding work in exactly these spots.
