Mammoet completes Sweden’s milestone road transport

Together with Martin Bencher Group, Hitachi Energy and Ellevio, Mammoet has completed Sweden’s heaviest and longest road transport. The job included moving a giant transformer weighing 390 tons through central Sweden.

This transformer, which alone weighs about 80 elephants, will eventually ensure that the electricity produced at a wind farm in Ånge can be transported further to Swedish electricity customers.

The transformer was transported along public roads in Sweden, but not without some challenges. As Swedish roads are generally not adapted for these massive weights, lengths and sizes, several roads and bridges needed to be adjusted to complete the transport.

To name a few things, the road was lowered under three bridges, a belly trailer was added in order to cross five bridges, partners used a flyover bridge, de-electrified five railroad crossings, built new roads, barriers, and lights were dismantled.

With the help of detailed route surveys, Mammoet’s Trojan trucks, 32 axle lines of conventional trailers and a Girder frame, were able to transport the transformer safely to its destination. Final positioning onto the foundation was done by means of a jacking and skidding operation.

Martin Bencher, that was contracted by Hitachi Energy to transport the transformer noted that the move took more than three weeks. The transformer itself is 12 meters long, with the whole convey having a total weight of 762 tons, and being 5,5 meters wide, and 105 meters long.
