Lighthouse Moves with Enerpac EVO Multipoint Synchronised Lifting
Rescuing a 120-year-old lighthouse from coastal erosion called for precision lifting and control; Danish heavy lifting company, BMS Krangården, chose an Enerpac EVO multipoint synchronised lifting system for the move. Located on the north-west coast of Jutland in Denmark, the 700 ton ‘Rubjerg Knude fyr’ was safely moved 70 meters inland in just 6 hours.
Shifting sands and coastal erosion from North Sea winds and waves are a serious problem in the area. It was inevitable that without relocation the iconic lighthouse would collapse onto the beach in just a few years. BMS opted to lift and move the lighthouse in one piece rather than dismantle it brick by brick.
The company inserted twenty-four high tension steel rods beneath the 23m high lighthouse. These were then attached to a custom-built steel frame with concrete anchors providing a platform for the lighthouse to rest on. Sixteen Enerpac HCR-200 185 ton cylinders were then installed under the steel frame to lift the lighthouse.
An Enerpac EVO 8-point multipoint synchronised lifting system was used to control the HCR-200 cylinders and two 45 ton jacks used to push the lifted tower along a pre-laid track. The EVO system simultaneously controlled all the cylinders creating a highly accurate and synchronised lift. Accuracy was critical for moving an important piece of Danish heritage safely to its new home.
“We needed a controlled multipoint lift that ensured the stability of the ‘Rubjerg Knude fyr’ lighthouse during the move, the Enerpac EVO multipoint synchronised lifting system is ideal for this and worked perfectly,” said Henrik Jonsson, Department Supervisor Projects, BMS Krangården.
The 70m move further inland is expected to secure the future of the ‘Rubjerg Knude fyr’ lighthouse until at least 2060.
