Hardenberg – other models: the collective page of trailers outside the named ranges, from AT 12 through B1500 to BT 2000, 370 to 4,255 kg unladen weight, 1,500 to 14,000 kg gross weight
This page gathers the Hardenberg trailers the register could not assign to a named range. Listed here are the types AT 12, B1500 and BT 2000, with no shared numbering logic or model-year sequence readable from the names. As with many smaller trailer brands, the programme is drawn from registration data, in which each model is listed individually with its technical values.

The register lists here 3 versions with unladen weights from 370 to 4,255 kg, gross weights from 1,500 to 14,000 kg and widths from 2,080 to 2,250 mm.
The span of gross weights runs from the light class towable behind a car up to heavy, multi-axle trailers as towed behind lorries and tractor units in commercial transport. The range reflects a model programme running from simple feeder trailers to load-bearing versions for hauling materials, without one single market niche standing out.
On a used example, the lighter versions call for checking axle, wheel-bearing and overrun-brake condition, the heavier ones additionally the brake system, axle assemblies and the frame for corrosion and cracks; lighting, the plug and tyres and rims count on all of them. For a brand with such a small model programme, parts usually run through independent trailer workshops rather than a maker's own network. On versions with an overrun brake, the adjustment of the brake linkage and the condition of the brake linings are also worth checking before the first drive.

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.
