Janssens – other models: the collective page of trailers outside the named ranges, from B2 to BK 8.5, gross weight 2,000 to 20,000 kg, unladen weight 600 to 5,400 kg
Janssens carries on this collective page trailers the register could not assign to a named range, from light models such as B2 and B2A to the heavier BK6 and BK 8.5, whose numbers echo the weight class in tonnes; JANSSENS and MAN350 stand alongside for further individual builds on this collective page.

The register lists here 7 versions with unladen weights from 600 to 5,400 kg, gross weights from 2,000 to 20,000 kg, lengths from 5,780 to 12,000 mm and widths from 1,860 to 2,550 mm.
The span runs from small class O2 trailers for trade and agricultural use to class O4 trailers for heavy-haul work; such collective pages usually bundle a maker's whole side programme alongside its main named ranges. The smaller models tend to work on farms, the larger ones in building-materials and heavy-haul transport.
On used examples, depending on size, frame and load floor, overrun brake and ball coupling matter on the smaller models, and on the heavier versions axles, brakes and frame welds, plus rust on load-bearing parts; spare parts for standard components are widely available, while special parts are best sourced from the manufacturer. A look at the service history shows, on the heavier models, whether axles and brakes were checked regularly, and the condition of tyres and suspension reveals how the trailer was actually used.

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.
