Smit – other models: the collective page of trailers outside the named ranges, from the light water trailer to heavy tank and special semi-trailers, 300 to 24,890 kg unladen weight, 900 to 39,000 kg gross weight
This page gathers the Smit trailers the register could not assign to a named range. The programme runs from light versions such as the 1860 Wateraanhangwagen – Dutch for water trailer, a mobile water supply on wheels – through the AW, ATS, DTEA and STO ranges to markedly heavier versions; one model simply carries the designation Mobile Equipment. The span of type designations from two- to four-digit numbers shows a programme combining several trailer classes under one brand.

The register lists here 45 versions with unladen weights from 300 to 24,890 kg, gross weights from 900 to 39,000 kg, lengths from 4,180 to 13,790 mm and widths from 1,350 to 2,560 mm.
Such a span from the light water-trailer class to the heavy-transport semi-trailer occurs with makers whose range, alongside series models, also includes special versions for agriculture, water supply or construction and haulage.
On a used example, on the light water and utility trailers the condition of the tank or container, axle and lighting count, on the heavy versions additionally axles, braking system and frame under high payload and rust on load-bearing parts; spare parts, depending on the version, run through the general trailer market or specialist commercial-vehicle suppliers.

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.
