Aku Other models

The register lists 18 versions with kerb weights from 270 to 1,060 kg, gross weights from 1,400 to 3,650 kg, lengths from 4,257 to 10,414 mm and widths from 1,912 to 2,600 mm. The large number of models within comparatively narrow weight bands shows a fine grading within the light trailer class.

With gross weights mostly below 3,500 kg, most of this range falls within EU trailer category O2, for which an overrun brake is required; the heaviest version slightly exceeds that limit and already reaches into category O3, where an overrun brake remains permitted only with separate type approval. Towing behind a car needs licence category B or BE depending on the combination's gross weight; on the long versions built for boats, the nose weight at the ball coupling shifts with the boat's position on the trailer and is worth rebalancing by moving the load before setting off.

Trailers of this size carry boats, machinery or loads up to 3.5 tonnes and are aimed at tradespeople, clubs and private users. The fine model grading allows a suitable length and payload to be offered for different loads without exceeding the weight limit for a standard trailer licence.

When buying used, check the condition of the chassis and loading floor, the operation of the overrun brake, the condition of axles and tyres and, on the longer versions, the load capacity of the drawbar. Parts such as axles, brakes and lighting are available through the general trailer trade.
