Smit ST – semi-trailers and trailers from 4.5 to 32 tonnes gross weight: 5 versions, unladen weight 1,920–10,020 kg, widths up to 2,500 mm
The ST range gathers Smit trailers and semi-trailers in the register, spanning light to heavy versions. Type designations such as ST 3-6 and ST 12-32 correspond to the payload in tonnes of the respective version, while ST 1230 and ST 0306 state the same values in a different notation. Depending on version, the trailers in this range span EU vehicle categories from O3 (3.5 to 10 tonnes) to O4 (over 10 tonnes gross weight), covering several registration tiers of the heavy segment.

The register lists here 5 versions with unladen weights from 1,920 to 10,020 kg at a gross weight of 4,500 to 32,000 kg. Widths range from 2,160 to 2,500 mm.
The wide span from 4.5 to 32 tonnes gross weight shows that the ST range does not cover a single weight class but several payload tiers under the same type designation – from a light tandem-axle trailer to a heavy multi-axle semi-trailer for freight transport.
When buying a used trailer or semi-trailer from this range, check above all the frame and axles for rust and wear, the condition of suspension and brakes, and, depending on size, the coupling, tow eye or fifth wheel; on the heavier versions it is also worth checking frame reinforcements and tyre condition. Spare parts are available through the general trailer and semi-trailer parts trade. It is also worth checking tyre age and tread depth, the function of the lighting system together with reflective markings, and proof of the periodic roadworthiness inspection.

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.
