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 |

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.

Good lord at the amount of cable needed
Potain MDT128
Can you just imagine how much that thing sways when the wind picks up.
[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.] |

The Manitowoc S-282. Not the biggest or baddest around but she gets the job done and is in and out quick fast and in a hurry."

In the past few years, very few cities in America have seen more tower crane construction than Chicago. The current king of the landscape, a Potain MD 485 tower crane, was provided and erected by Central Contractors Service, Inc., a member of the ALL Family of Companies. See the press release below to learn more about this thousand-foot tall crane.
[They used steel rope lengths of 1500', 1850' and 2850'.]

An impressive photo capture of 5 tower cranes standing tall above the buildings of downtown Chicago's West Loop; one of the cities fastest-growing neighborhoods. These tower cranes, in addition to a large portion of the many other cranes found throughout downtown Chicago, are supplied by Illinois based Central Contractors Service, a member of the ALL Family of Companies. |
There are some Potain cranes working on the Tappan Zee Bridge.
