Sommer SG – the semi-trailer range from the Osnabrück manufacturer: versions from the SG 18 to the SG 800 RT, 10.1 to 13.9 m length, 4.0 to 8.76 t unladen weight and gross weight up to 35 t
The SG range denotes semi-trailers at Sommer Fahrzeugbau of Osnabrück. The versions recorded in the register reach lengths well over ten metres and gross weights up to 35 tonnes, placing them clearly in this vehicle class rather than among the manufacturer's lighter trailers. The type designations range from the SG 18 and SG 50 through the SG 100, SG 100 T and SG 160T to the SG 200 T-A, SG 240T-ATX, SG 299T and SG 800 RT; the suffixes T, AX and ATX mark different chassis and axle versions.

The register lists 16 versions with unladen weights from 4,000 to 8,760 kg, gross weights from 8,600 to 35,000 kg, lengths from 10,100 to 13,900 mm and widths from 2,500 to 2,550 mm.
Semi-trailers of this size carry general cargo, machinery, building materials or swap bodies in long-haul transport and are pulled by tractor units of various makes; the span from just under nine to 35 tonnes gross weight covers both lighter box trailers and heavy low-loader versions.
On a used semi-trailer of this size, the condition of axles, brakes and air suspension, rust on the frame and kingpin, the tightness of the tarpaulin or box body, and tyres and underrun protection all count; a current roadworthiness report belongs in the check before purchase. The condition of the landing legs and the fifth-wheel coupling plate, along with a complete set of tyres with sufficient tread depth, also belongs in the 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.
