They say what goes up must come down so it should come as no surprise that they've finally figured out how to get the last of the three cranes sitting atop Tokyo's soaring Sky Tree tower down once and for all. If you been following this series you'll know that we've been wondering if the architects and engineers had any idea of how on earth they were going to make that last crane's descent from the heavens happen. Apparently they've had a really big idea all along which just got smaller and smaller and smaller.
Readers of the series will know that workers dismantled Crane Number One and lowered it form its perch via Crane Number Two. They then repeated that feat to lower Crane Number Two with Crane Number One. That left just one lonely crane standing 634 meters up in the sky. How in heavens will they get crane Number One down you ask?
The answer is amazingly simple (it's the kind of solution I would have come up with). Workers will dismantle Crane Number One and then assemble a smaller crane, we'll call Crane A. They will then use Crane A to lower Crane Number One. Then they will dismantle Crane A and assemble an even smaller crane (let's call that crane, Crane B) to bring Crane A down to the ground. They will repeat the process over and over again until finally they are left with a crane that is small enough to fit in the elevator and leave with it via the front door just like everybody else.
