Knapen KOCF – walking-floor semi-trailer for bulk goods and biomass from Deurne: six versions with 30,000 to 48,000 kg gross weight, lengths up to 14.1 m
Knapen Trailers of Deurne, inventor of the European walking-floor semi-trailer, builds the KOCF range for bulk goods, biomass and agricultural loose cargo alongside its closed-box models. The models KOCF, KOCF 10 L, KOCF 100, KOCF 10L and KOCF 200 differ in loading volume and body height; in this range the number in the type designation follows the loading volume in cubic metres, as seen on the KOCF 100 model with around 100 m³ of volume.

The register lists 6 versions with unladen weights from 7,000 to 10,100 kg, gross weights from 30,000 to 48,000 kg, lengths from 12,730 to 14,100 mm and a width of 2,550 mm.
These semi-trailers carry light to medium-weight, high-volume goods such as wood chips, green cuttings, grain or recycled material, where loading volume matters more than sheer tonnage; competition ranges from specialised walking-floor makers to conventional tipper combinations, depending on whether the load can be tipped out. Their aluminium construction keeps unladen weight comparatively low despite the long, reinforced floor needed for continuous pushing operation.
When buying used, the floor slats and their guides, the floor's hydraulic drive, the tarpaulin or side boards and the seals on the floor and side walls deserve particular attention; add to that the frame, axles and brakes, which are put under heavy strain on the long, highly loaded semi-trailers in this range.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
