Närko 23PP3-AL18

The trailer is 13,680 mm long and 2,550 mm wide, with an unladen weight of 6,150 kg. That gives a payload of 34,350 kg, more than five times its own weight, pointing to a light frame combined with a long load length rather than to massive structural members. At 13.68 m long, it is one of the longer builds within this weight class.

For trailers in this weight class, air brakes with a two-line system are required, as on all O4 trailers. The rig is driven on licence category CE, since the gross combination weight is well beyond the limits of the lighter categories. The towing vehicle's coupling and air supply must also be rated for this length and load.

With such a light construction over such a long body, check the frame along its entire length for sagging and cracking at the cross connections, especially around the middle of the frame. Also check: condition of the axle bearings, brake system, tyres, the coupling, and a valid roadworthiness inspection.
