At a gross weight of 3,500 kg and a kerb weight of 1,150 kg, the trailer carries a payload of about 2,350 kg, more than double its own weight. With six wheels across a width of 2,100 mm, the load is spread over several axles with a comparatively narrow track, suiting a compact, manoeuvrable trailer in this weight class.
A trailer with six wheels in this weight class is built for even load distribution within compact dimensions, for instance for cargo that calls for a low load per wheel, such as delicate or heavily demanding goods. Here the overrun brake acts through the drawbar on all axles together and needs to be adjusted evenly across them.
When buying used, the suspension of the several axles deserves particular attention, as does even wear across all six tyres as a sign of correct load distribution. The overrun mechanism at the drawbar should be checked for play and corrosion, and the lighting together with its connector for correct operation. The drawbar coupling itself is also worth checking for wear, since it transmits the pulling force between this light, multi-axle trailer and the towing vehicle.
