Self-Erecting Tower Cranes and Potain

Thumbnail on Potain
I'm seeing evidence that a mobile crane is not necessarily a telescopic-boom crane. It might be carrying a self-erecting tower crane.

I didn't use the embedded version of this Liebherr MK-88 video because it was click bait. The contents is actually more interesting than the thumbnail. The man in the lower-left corner is the operator that is using a remote control to control the crane.

The next day I came across a reference to "Potains."

The girlfriend took me to Chicago last weekend ...lots of potains around the city
From above picture
I spotted two cranes in the above picture and they both seem to have the design of self-erecting tower cranes.

Potain was founded in La Clayett, France, in 1928. It is now a subsidiary of Manitowoc that makes tower cranes.

[If I hadn't already read the above posting, I would not have known that the comment was referring to the tower crane. I'm frustrated that none of the comments indicate where this bridge is being built.]

[Only two of the possible five tower segments are out. They are probably still erecting the tower part.]

[This must be what it looks like when it is "folded up" for transport.]

There are some Potain cranes working on the Tappan Zee Bridge.

Video of Grove GTK1100 being set up, doing work such as building a windmill, and coming down.

There is currently (Summer 2017) a crane erected just a few blocks from where I live.
