Walking-floor trailers unload without tipping, pushing the load rearwards with moving floor slats, which makes them suitable for sensitive bulk material, silage or recycling material; in this niche segment Knapen, alongside makers such as Fruehauf and Groenewegen, ranks among the better-known European suppliers, whose vehicles are used mainly in the waste and recycling trade and for transporting bulk agricultural produce such as silage or compost.

When buying used walking-floor trailers, check above all the condition and smooth running of the floor chain and its drive motor, wear on the floor slats and side walls, the tightness of the hydraulics, the state of axles and brakes, and corrosion on the frame and chassis; spares for the walking floor are usually only available directly from the manufacturer, so it is worth asking about parts availability before agreeing a price.
