The register lists here 12 versions with unladen weights from 4,580 to 10,560 kg, gross weights from 20,000 to 40,000 kg, lengths from 11,520 to 14,040 mm and widths from 2,510 to 2,600 mm.
With gross weights from 20 to 40 tonnes and lengths of over 14 metres, the SR semi-trailers are built for heavy long-haul freight transport; such semi-trailers are switched between different tractor units at hauliers and stay in long-haul service for many years. As a semi-trailer the SR is coupled to a tractor unit and driven in professional haulage with a CE driving licence.
When buying a used semi-trailer of this size, what counts is the condition of the frame and kingpin, the function of the brakes and air suspension, corrosion on load-bearing parts, and the condition of the axles and tyres; parts for the running gear and braking system are available through the general commercial vehicle trade. The landing legs, the connections for brake lines and the electrical socket, and the ABS and EBS electronics also belong in the pre-purchase check.

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.
