Salvage of a 102 tons Glacial Erratic Rock | Heavy Haulage

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.  Answer: none.  That's one impressive rock.  Even more impressive is the machines used to lift it and transport it.  After they discovered this rock and estimated the weight, how many years did it take to design and build the crane and the machine needed to transport it  Back in the 80s - lived in PNG (Bougainville) - our house was on a hillside and clearing vegetation we found a large boulder - asked Geologist - about 130 tons - we asked how it got there - he said ejected from volcano - about 65kms away - We asked "Prehistoric" - No - in the last 100 years...  yikes...  We live in a part of Baja Mex where all is rock,it is call La Rumorosa, ( 32º32'06" N , 116º03'00" W) 1200 meter high rock mountain, we just had a friend visiting from a flat land area in Canada, he was fascinated ...nice video  Super respect for the engineering feat and recovery.  I just can’t grasp the reason for using the manpower, machinery, time, and effort.  We have some erratics around Oregon estimated around 10K old since deposition and they are above surface layer.  I just can’t understand why this one was dug from so deep.  I would think a smaller one might require less effort to move. But Anyhey, it’s more impressive that they moved so much mass with huge machinery in such a short time. No telling how much time it spent atop a glacial raft.  That’s great; going through town!!
