Hello; The equipment used to actually transport the rock is amazing. Love watching all the axels moving independent of the others to get the job done. Amazing. Salvage of a 102.5 tons heavy glacial erratic rock on a field near Hüven, Germany on December 4, 2020. Heavy equipment was used for the recovery: A 9-axle 800-tonne crane (Liebherr LTM 1750) was needed with an originally estimated weight of up to 140 tons. The erratic is a granit rock that was transported from the ice masses of Scandinavia to the site near Hüven during the Ice Age about 200,000 years ago. Rocks similar to this were found in the construction of Kansas City's airport, but they were not as big. They needed to be removed so piles could be driven for foundations. Nobody knew what to do with them, so they lined them up by a terminal. Someday archeologists will be debating what astronomical alignment they were meant to mark.
