Rohr – other models: German tank and silo semi-trailers for bulk goods and liquids, 980 to 12,500 kg kerb weight, up to 38,500 kg gross weight
Rohr is a German manufacturer of tank and silo vehicles for transporting bulk goods, liquids and silo material by road. This collection page lists the versions that could not be assigned to any named series; type codes such as RAK, RSK, RSB or TAL combined with numbers for tank capacity and axle count distinguish the individual designs.

The register lists 23 versions with a kerb weight of 980 to 12,500 kg and a gross weight of 2,000 to 38,500 kg. Length ranges from 4,280 to 13,900 mm, and width from 2,200 to 2,600 mm.
Tank and silo semi-trailers of this size carry feed, building materials such as cement and lime, and liquid goods for agriculture and construction. The German market is highly specialised, with a small number of manufacturers working closely with hauliers and agricultural dealers, designing tanks to suit the specific cargo.
When buying used, check the inner tank walls for corrosion and material fatigue, particularly with aggressive bulk goods, and check the seals of discharge flaps and compressor fittings on pressure-discharged silo vehicles. Frame, axle assemblies and brake system should be checked for rust and wear as with any heavy trailer; spare parts for tank fittings are usually supplied by the manufacturer itself or by specialist workshops.

- 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.
