Steel conveyor bridge dubbed 'horizontal Eiffel Tower'

Germany With a length of 502 m and a weight of 13,600 tons, the F60 conveyor bridge is even more massive than the famous Eiffel Tower.

The giant steel conveyor bridge F60 in Lower Lusatia, Brandenburg, Germany, is one of the world's largest and longest movable industrial engineering machines.

A conveyor bridge is used in mining to remove topsoil (the top layer of rock and soil that needs to be removed to access the coal seam or ore below) and dump it into an open-pit mine tailings dump. The F60 is the last of five similar-sized conveyor bridges built between 1969 and 1991. Four of these are still in operation in the brown coal mines of Lower Lusatia, while the F60 is preserved as a tourist attraction.

The F60 is 502 m long and 80 m high. Due to its large size and the shape of its steel truss, the F60 has been nicknamed the “horizontal Eiffel Tower.” But in reality, if the Eiffel Tower were placed side by side with the F60, it would be completely dwarfed, as it is only about 330 m high. The F60 is also much heavier. It weighs 13,600 tonnes, while the Eiffel Tower’s steel frame weighs around 7,300 tonnes. It is one of the heaviest land vehicles ever built, surpassed only by the giant 14,200-tonne Bagger 293 wheeled excavator.

During operation, the F60 is accompanied by two bucket excavators, which together dig and move 29,000 m3 of waste soil per hour, equivalent to a weight of 50,000 tons. Despite its huge size, the F60 is very economical, requiring only 1.2 kWh of electricity to collect, move and dump one m3 of waste soil.

Construction of the F60 began in 1988 and the machine went into operation in 1991. After just 13 months, the mine was closed and the German federal government ordered the area to be reclaimed. The original plan was to dismantle the F60, but it was later preserved as a tourist attraction.
