Niewiadów – other models: collective page of the Polish car-trailer maker outside the named ranges, type codes B, H and C, 270–2,120 kg unladen weight, up to 3.5 t gross weight, class O1/O2
Niewiadów is a Polish manufacturer of car and utility trailers whose plant in the town of Niewiadów in Łódź Voivodeship has built light trailers for private and commercial use since the 1970s. This page gathers the Niewiadów trailers the register could not assign to a named range. The codes B, H and C denote different ranges, with the four-digit number after them giving the approximate payload or gross weight in kilograms, such as B1300 or H1300.

The register lists here 98 versions with unladen weights from 270 to 2,120 kg, gross vehicle weights from 850 to 3,500 kg and widths from 1.82 to 2.55 m.
Niewiadów trailers are among the most common car trailers in Poland and are used to transport garden waste, building materials, furniture and small machinery. Their low unladen weight makes them towable by almost any mid-size car. Because of the large numbers built, used Niewiadów trailers can be found on the Polish market at almost every price point, many dating from the 1980s and 1990s.
When buying used, what counts is the condition of the frame and loading deck for rust-through, especially at the drawbar and wings, the condition of the axle, wheel bearings and tyres, the function of the overrun brake on braked versions, and the tightness of the side panels and tarpaulin. Spare parts are widely available in Poland.

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.
