Since I've written about Manitowic's 4600 stringer and 13000 ringer, it is only fair that I write about "the most powerful conventional crawler crane in the world." (That statement makes me wonder what an unconventional crawler is. Evidently it is the use of a "derrick basket." [Liebherr]) Modern cranes are built from modules. Modules allow the same equipment to be assembled in different configures for different job requirements. For example, a light load with a long reach vs. a heavy load with a short reach but high vs. a very heavy load with a short reach and height. The size of the modules are supposed to be small enough that the modules can be transported on roads. Liebherr configured their LR 13000 " in its maximum lattice boom configuration at the manufacturing plant in Ehingen, Germany." "The combination of the 120 m main boom and the 126 m luffing jib produces a lattice boom system with an overall length of 246 m. Mounted on the solid crawler chassis, the crane thus reaches a height of 248 m" [HeavyLiftNews]
Basically, it was a PR stunt like the following photo.

The different configurations of the crane are tested at the factory.

| Liebherr Crane Fans posted LR 13000 is being tested Alan Shaw: Around 3,400Mt on the hook then! James Rose: Can also be arranged with a massive luffing jib to lift 300 tons up to a hook height of 240m / 800ft. Tony Sorritelli: Interesting they decided on such a steep angle on the upper spreader bar. |

| Martin Garner Pedersen commented on Liehberr Crane Fans' post On this picture the LR 13000 is equipped with power boom and is test lifting 3750 metric tons. David Whitehead: Martin Garner Pedersen yep. 125% test. |

Crane Operators Forum - Heavy Lift profession. posted Liebherr Construction LR 13000 on the test bed Andrew Rees: Do they test every crane that is made ? Andrew Bayes: Andrew Rees yes, they test them in every configuration that the customer has requested. [It is too bad that neither post indicated how much was lifted at what radius.] |

| Associated Wire Rope Fabricators, INC posted Do you have what it takes to control this monster? 💪 It makes those workers look like figurines. 🏗️ lr13000 📷 Heavy_Lift_Productions Chris Poff: Saw this in Toledo Ohio on my job site coming in, four simis to move one track. 170 simis to move Only six on the world. Of these massive crawlers! Michael Austermiller: Chris Poff Cleveland Cliffs a few years back. [Presumably building their HBI Plant.] Gregory Curry: Fort, McMurray Alberta Canada, is going to do one of its biggest and heaviest Crain lifts ever. It’s taking 6-8 months just to install and drill piles down to bedrock, to support the Crain, it’s going to take 6 months to setup the Crain. 200 M in hight and lifting capacity 612 ton. Angel Simulata: I got the DEMAG CC8800-1 it's a 3,200 tons capacity |

In the following video they lifted a mobile crane as the load. Judging from this photo, someone was in the cab when it was lifted. I learned that crane operators call that "meat on the hook."
They need to park a pickup truck or something next to one of those crawler tracks for scale. But judging from the cab and handrails, those tracks are huge. Specifically, I don't think one will fit on a flatbed trailer. I wonder how they disassemble the base base unit for transport to a new work site.

For the assembly of the block for this heavy-lift PR stunt, see cranes. It also has better views of the "derrick basket" configuration.
Update: Liebherr's beginnings: Steve Robinson posted two photos with the comment:

In 1949, the mobile tower crane is inventedIn post-war Germany, many parts of the country need to be rebuilt. Hans Liebherr manages his parents' building firm in South Germany. He recognizes the need for tools and machinery for the building industry and domestic construction. Together with design engineers and tradesmen, he develops the first mobile tower crane in 1949. The TK 10 can be transported easily and is simple to set-up at the construction site. It is also the first product of the Hans Liebherr Maschinenfabrik (engineering works), founded in 1949 in Kirchdorf. As successor models follow, crane production at Liebherr picks up pace and the construction company turns into a manufacturer of construction machines.

| Tom Marshall posted massive crane at BP Whiting around 2013 - this is when they were loading the counterbalances. Not exactly steel mill stuff but you could throw a rock from here and hit the old Youngstown S&T J&L etc. mill. Northwest Indiana is still going strong. https://www.chicagomag.com/ |

| Crane AZ posted The LR 13000 is the most powerful conventional crawler crane in the world. One of its main areas of use is power plant construction. |
A video describing the crane. (source link)
(new window) A video of first lift (source)
(new window) The first six minutes include the LR1750-2. It is rated at 750 tons and can be almost 200 meters tall. After they talk about so me mobile cranes, they show the assembly of the LR1750-2. I think I have watched this video before, but I can't remember where I noted it. The narrator says it took a half-hour to raise the boom. At 26:09 the video say LR13000 is still the largest crawler crane.
(new window) (source)
Video of worlds largest crawler crane in operation (shared again) Note that it starts with building a modern windmill.
In Sept 2020, I got hit with a Double Doomsday. Both Facebook and Google changed their software. I said "changed" instead of "updated" because the new software is not better. In fact, Google's Blogger software is far worse except for a search function that works. For example, it has three bugs concerning photos and their captions. So I'm no longer copying photos and interesting comments from Facebook. I'm just saving the link. Unfortunately, some of the links are to private groups.
