Over the last months two new wind turbines were erected about three miles from my place. These are the biggest ones on can currently buy with a maximum output above 6 megawatt each. Yesterday the blades for the second one were lifted to the top of the 135 meter high tower. The crane used was a brand new Demag CC9800-1 and the lifted nose section with the three rotor blades weighted 369 metric tons.
The tower is a hybrid of concrete and steel, hub height 135m. The rotor blades are so large they are built in two sections, a first except for some experimental machines (I believe.)
the final lift is the hub section and three blades already fixed, weighing 369 metric tonnes.
There are at least five guys in this picture, and another standing atop the nacelle waiting for the pick to arrive.
Simply amazing.
