How operation of this machine is different from pretty standard small derrick cranes? Like Liebherr DR? Or even spider cranes (Maeda & others)?

  The Liebherr you reference is a dismantling crane, so obvious difference in usage there, and spiders/mini crawler are mobile cranes. The Skypicker is bolted to the floor of the building, and when the next level is ready to go in, it hauls itself up to the height of the next floor through a hole, which is then finished around the crane, which is once again bolted to the floor. The last 30 seconds of the video on this page show how it relocates: http://vertikalsolutions.net/products/ http://vertikalsolutions.net/products/

    I watched that video on that page earlier, but now that I saw your description, I'm wondering how they get it down again at the end!

    Any clue as to what they do with the hole on each floor after they lift the crane through it?
