De Graaff Trail FK 3500/20/4/445/90 – EU class O2 trailer: 3,500 kg gross vehicle weight, 600 kg unladen weight, 6.93 m long, built 2002
With a gross vehicle weight of 3,500 kg, the De Graaff Trail FK 3500/20/4/445/90 falls into EU trailer class O2, trailers between 750 kg and 3.5 tonnes. This class usually runs on an overrun brake, which works purely mechanically as the drawbar compresses when the towing vehicle brakes.

The FK 3500/20/4/445/90 was built in 2002 and has an unladen weight of only 600 kg; against a gross vehicle weight of 3,500 kg, that leaves a payload of 2,900 kg. Overall length is 6,930 mm, width 2,200 mm.
An unladen weight of just 600 kg against a gross vehicle weight of 3,500 kg gives a very high payload relative to the trailer's own weight, the kind a light, open frame without heavy bodywork allows. At close to 6.9 m long and 2.2 m wide, the trailer is narrow enough for ordinary roads but long enough for bulky loads.
When buying used, a trailer in this class lives or dies on the override mechanism: it must compress and extend smoothly, with no play or corrosion in the guide. The checklist should also cover brake cables, linings and the reversing lock, axle bearings, tyres and tread depth, and lighting; with such a light frame, also check for twist, dents and rust along the long, narrow chassis and its floor. With a build year of 2002, check the spare-parts supply for brakes and axles as well.
