One of Denmark's northernmost lighthouses. Rubjerg Knude was built 200 meters from the 60 meter high cliffs over the North Sea and first lit in 1900. But coastal erosion during the last 119 years has taken all but about 20 meters and the lighthouse was destined to fall down the cliff in a few years. But thanks to a clever solution the lighthouse was put on wheels instead and this morning October 22, 2019 at 9AM, and for 6 hours the lighthouse was moved 65 meters back from the cliff, which gives them about 40 more years to figure out a permanent solution... This timelapse was made from 2300 still images taken on a Canon 6D with exposures from 4-13 seconds at 10-15 second intervals and is a 240X actual speed.
To be able to move the lighthouse the foundation first had to be strengthened and giant steel girders run through the base of the building. A 14 meter wide path was prepared, packed and leveled. Steel plates were layed as a foundation and then steel rails mounted on top of the steel plates. Wheels were mounted on the rails and then the entire structure was lifted with hydraulic jacks under the supporting steel girders. When it was time to move computer controlled hydraulic arms mounted behind the lighthouse locked into slots in the rail and then pushed the lighthouse forwarded. When the hydraulic arms were fully extended they released from the slots in the rail, contracted and engaged with with the next set of slots and the process was repeated. The original pace was intended to be 8 meters per hour, but it turned out the lighthouse weighed less than anticipated and the actual pace was closer to 13 meters per hour.
This method of moving the lighthouse is frequently used to quickly move new bridges into place under existing roads and highways when upgrading infrastructure.
The cost of the move is 5 million DKR.
