Sigma – other models: the collective page of trailers outside the named ranges, from 30PF 31-T8 to Sigma-Trailer, 390 to 1,300 kg unladen weight, 1,200 to 3,500 kg gross weight
This page gathers the Sigma trailers the register could not assign to a named range. The listed types 30PF 31-T8, 5, RPPS 03, Sigma-ST-2500 and Sigma-Trailer range from short technical codes to designations that carry the brand name itself. 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 6 versions with unladen weights from 390 to 1,300 kg, gross weights from 1,200 to 3,500 kg, a length of 7,970 mm and widths from 1,600 to 2,450 mm.
With gross weights up to 3.5 tonnes, the versions cover the whole braked trailer class up to the category B licence limit; the spread of unladen weight from under 400 to over 1,300 kg shows that both light open trailers and considerably heavier versions are listed under the brand name. The length of nearly 8 metres is among the larger versions in the programme.
On a used example, axle and wheel-bearing condition, the function of the overrun brake and its linkage, rust on frame and drawbar, the state of lighting and plug, and tyres and rims all count; on the larger and heavier versions the condition of the load bed and body as well. Parts for such small brands usually run through independent trailer workshops rather than a maker's own network.

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.
