The trailers are mainly used for transporting potatoes from the field to the factory. To reach an overload height of 3,300 mm, the aluminium trough in this application was fitted with a side panel height of 1,570 mm. To be able to continue to utilise the maximum transport capacity, the trough has a long design. The total load volume achieved is 38 m³ with a permitted overall weight of 34 tonnes. A powerful press at the front ensures additional stability during the tipping process. The hydraulic tailgate lifts up high above the cone of the material and is integrated optimally into the side walls so that even cargos which do not slide easily can be unloaded without any problems.

With the Tridec steering system installed, the third axle is fitted under a turntable and is force-steered by the Tridec steering system mechanically from the coupling plate. High manoeuvrability and low tyre wear in tight turning circles are the positive results. For unladen trips, the first axle is designed as a lifting axle. The air suspension ensures balanced ride comfort. The coupling height of the trailer is 1,350 mm, this can be extended to suit the tractor unit up to 1,450 mm.

Despite many other special options, such as a catwalk, a roller tarpaulin and a plug-in triangle, the SMK34 has an empty weight of 8,900 kg. With its MAN tractor unit, the overall vehicle combination tips the scales with 17,620 kg overall weight giving a payload of 22,380 kg.
