Kraftdragarna AB Delivers 343t Transformer Making Stockholm City’s Heaviest Ever Road Transport Record

Kraftdragarna AB, based in Västerås, about 90km west of Stockholm, was commissioned to carry out the heaviest ever road transport through the city of Stockholm.

The dimensions of the load, a 343t transformer, were:

• 10m long
• 4m wide
• 5m high

The transformer arrived by barge from Norrköping at Hammarby quay in Stockholm.

From the barge landing Kraftdragarna AB transported the transformer by road to the electricity sub-station in Högdalen over night from 11 to the 16 September.

Such a transport requires flawless planning and extraordinary execution.

Overhead cables, traffic signs, bridges and restrictions on the proposed route all need to be planned long before the transport.

Extra difficulties experienced during this project included the need to skid the load under a bridge too low to enable passage on the trailer and…

…strengthening bridge’s that were unable to bear the combined weight of the transformer and trailer.
