The Tankmobil T4 Sta 656 is a trailer from Tankmobil (EU vehicle class O4), registered as built in 1999. It is 12,500 mm long and 2,550 mm wide, weighs 9,390 kg unladen and has a permitted gross weight of 42,000 kg.
The Tankmobil T4 Sta 656 offers a payload of 32,610 kg – the gap between unladen and permitted gross weight. More than half of the gross weight is therefore available for cargo.
With a permitted gross weight of 42,000 kg the trailer exceeds the BE limit of 3,500 kg. It requires a C1E licence as long as the combination stays within 12,000 kg, otherwise CE – in practice behind a truck or an agricultural tractor.
Among the 14 trailers from Tankmobil with a stated length, the Tankmobil T4 Sta 656 at 12,500 mm is in the middle of the range (rank 3); the range runs from 9,950 to 13,700 mm. The Finnish vehicle register lists one unit – one of the brand's most common models.
Tankmobil T4 – tanker trailer series: six versions of the T4 series from 6,700 to 13,640 kg kerb weight, 34,500 to 42,000 kg gross vehicle weight and up to 13,700 mm in length
Tankmobil T4 is a series of tanker trailers listed in the register; the name already carries the tank body in it. The T4 designation is combined with codes such as DSA, LS, Lr or Sta and a number, for example T4 DSA 554, T4 LS 150 or T4 Sta 656, each with its own combination of weight and length in the register.

The register lists 6 versions with kerb weights from 6,700 to 13,640 kg, gross vehicle weights from 34,500 to 42,000 kg, lengths from 11,400 to 13,700 mm and widths from 2,500 to 2,550 mm.
With gross vehicle weights of 34.5 to 42 tonnes, the T4 series ranks among the heavy semi-trailers or centre-axle trailers used to transport liquid or gaseous loads in road tanker traffic; the kerb weight range of 6.7 to 13.64 tonnes points to different tank volumes or chamber numbers within the series. Tanker trailers of this size typically carry fuels, chemicals or liquid food products on the road and are subject to their own inspection and marking requirements depending on the cargo.
When buying a used tanker trailer, check above all the tightness of the tank, the condition of valves, lines and earthing connections, the operation of the braking system and air suspension, and corrosion on the frame and axles; current inspection dates for the tank and equipment should be checked before purchase. With the different T4 variants, it is also worth matching tank volume and chamber number against the vehicle documents, as these can differ between the DSA, LS, Lr and Sta codes. Servicing and spare parts are usually provided by workshops specialising in tanker trailers.

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.
