Huge Schnabel car for Amprion

08.10.2020

The grid expansion, that is necessary to create a sustainable energy future, entails many tasks for transmission system operators (TSOs), like planning procedures, overhead line construction, underground cable laying, upgrading and new construction of substations – and also, increasingly often, the transport of heavyweight transformers. To be able to carry out such transports in a plannable, flexible, and reliable manner and exactly at the time when it is needed for the implementation of important projects, the German TSO Amprion has now put its own Schnabel car into service. A Schnabel car is a special type of rail freight car designed to transport heavy and oversized loads. The load is suspended between the two ends of the Schnabel car by lifting arms to distribute the weight of the load evenly over many axles.

Amprion’s new transporting device is over 50 metres long, around 4.2 metres high, three metres wide and has 32 axles. When empty, it weighs 220 tonnes. In fact, it is the largest Schnabel car ever produced for the German market. The rolling heavyweight is capable of transporting all types of transformers that Amprion intends to install – including transformers and rotating phase shifters with a transport weight of up to 500 tonnes. The TSCNET shareholder is thinking long-term: The Schnabel car is to provide its service for a secure transmission system for the next 40 years.

On 6 October, the TSO was handed over the new Schnabel car at the heavy goods terminal in the Rhine city of Mannheim in Baden by the specialist company Kübler Heavy Rail. Hendrik Neumann, Amprion’s designated CTO, comments: “To implement the energy transition, we must adapt and expand our grid in such a way as to enable the integration of large quantities of renewably generated electricity.” For this, Amprion needs a large number of additional transformers and phase shifters, which the TSO can now transport across Germany with its new king-size Schnabel car.
