Some years ago I mentioned on this blog that I do like to build cranes. Lacking any serious equipment I prefer to make them from Lego.
Other engineers have better machine parks and can build bigger cranes, real ones. But they still have, like me, also fun playing with them.
They did so on the recent Liebherr customer day.
Here the biggest conventional crawler crane of the world, the LR 13000 with a maximum lift capacity of 3,000 metric tons, is lifting a LR 11350 (1,350 mt max cap.) which is lifting a LR 1350 (350 mt max cap.) which is lifting a LTR 1100 with (100 mt max cap.).
That is not all yet. That LTR 1100 is lifting a plate with a 1:50 model of an LG 1750 which lifts a 1:87 model of an LTM 1045.
Did I mention that engineers love to play?
The total weight of the six cranes assembly as shown, including all counterweights, is 5,000 metric tons and it is in perfect balance. Quite a mountain of high tension steel for a little playful show like this. By the way - 147 trucks are currently on their way to deliver the first sold 3,000 ton lifter for a refinery project in Whiting, Indiana (Here it is shown lifting its structural test load of 3,371 metric tons.)
More pictures of the six cranes lift are here, here and here. There are also a few videos showing the lift: here, a longer one here and another one.

Crane lifts crane, lifts crane,... Good metaphor for the present world order. What would the seismic threshold for the whole thing to fall down? Same thing to ask about the systemic threshold for this New World Order?

Here in Arizona we have tons of Sandhill Cranes here
Come watch! They are huge, and their combined wing beating noise along with a very loud bugle call is an experience that will give you goosebumps.

A bit bigger than the Liebherr I owned!

A seldom seen slice of reality on the builders of our human society, at least, in my small piece of the world. Incredible machines they are, and impressive folks who design, build and operate them. Begs the question, how can humans be so adept at building such things, and so inept at interacting with one another fairly?

The lost language of cranes, a novel by David Leavitt, tells in part, the story of an isolated little boy who learns communication through the movement of cranes.
what the brain throws up :)

Cranes are great! So non-controversial, like helping hands. Me, I've always had a soft spot for the grader. I'd love to take my grader for a ride, build a berm somewhere down the road, flirt with the waitress at a roadhouse, then come back the otherway...
