Sommer AW – trailer range of the Osnabrück manufacturer in the SpecCodex register: 12 versions with gross weights from 12,000 to 18,000 kg, lengths up to 9,310 mm
Sommer AW is a range in the SpecCodex register from the trailer manufacturer Sommer of Osnabrück. The models carry designations such as AW 12T, AW 16T, AW 18T or AW 18T-S, where the number gives the tonnage; suffixes such as -S, -UPS and -SUB mark different equipment and body variants. The model range spans from the simple base AW version to variants with additional codes for underrun protection or special tyres.

The register lists here 12 versions with unladen weights from 2,810 to 3,900 kg, gross weights from 12,000 to 18,000 kg, lengths from 9,100 to 9,310 mm and widths from 2,400 to 2,550 mm.
In the 12 to 18 tonne weight class, trailers such as the AW range are smaller two-axle versions, used in local and regional haulage as well as in agriculture and construction behind trucks and tractors. In this class, the AW range competes with numerous suppliers of smaller two-axle trailers in the German and western European market.
On a used trailer of this class, the frame and axles should be checked for corrosion and cracks, along with the braking system and the overrun device, the tyres and wheels and the lighting and electrics; on tipper or platform bodies, the load floor, sides and any hydraulics should also be checked. Spare parts for axles and brakes come from the common European 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.
