Manitowoc's 31000

This was Manitowoc's largest crane. It was unveiled on 9/19/2009. The ring turntable is carried on a frame that uses four crawler tracks. They made two of them before they moved crawler production from WI to PA. They did not move the capability to make any more 31000s.

A photo album of its first job, the Atlantic stadium. (A permanent link in case the album link goes away.) It took 130 truck loads to move it out.

It is currently one of the cranes helping to build the new Falcon Stadium. There also are two Liebherr 11000s in that bowl. Liebherr makes larger cranes, 13000, but these 11000s are no toys. The question was asked in a later posting "why did they need the 13000 if they already had two big cranes?" One answer said that there were some roof trusses that needed all three cranes to lift. But the two 11000s did set most of the time while the 13000 worked continuously, including lifting a man cage.

A year ago today, the 31000 stood tall for the first time outside of Manitowoc.

The comments on the above posting contain lots of photos of the new Atlantic Falcon Stadium construction. I include the following one because it is a closeup of the four-track transport platform. But the comments claiming this picture is in Atlanta have to be wrong. This has to be the Korean crane because it is building a plant instead of a stadium.


Comment on above posting.
[Note the mats to help spread the weight on the ground.]

Old news now but this photo of Chunjos 31000 and 18000 was in Cranes today mag.
Ben Stalvey posted two photos with the comment: "It's Manitowocs Mega Drum for the massive 31000."

Atlanta stadium
Ben Stalvey The big bad 31000Tony Reis It is in Atlanta during the build Joe Jenkins was there Barry Garret was over the build. 2,125,000lbs in counterweight in series 5 as the picture shows. On that job 262' of main 118' of luff.
[It can lift over 5 million pounds, but only 2 were made before the 2008 recession. And one is in Korea. The machinery to make more no longer exists.]

Holy moly..what's this?

This is probably not a 31000, but it is certainly a big ring crane.

Here's another good on of the 31000 making a 1,100,000# pick
[Lots of counterweights because they are shoved out about just half the possible distance.]

It's been an awesome experience to work with and next to this beautiful crane.

2013 For Sale for $22m. There are a lot of nice pictures of it working at a refinery. And some of it disassembled. I wonder if this is the one that went to Korea.
An animation of how it is assembled. Unfortunately, it doesn't show them coming off a truck trailer so I still don't have a good feel for what size loads are being carried on the highway. It obviously has a lot of hydraulic rams that are only used for assembly. 

The 31000 is done helping to build the new Atlanta Falcons stadium, so we will probably be seeing pictures of it being dismantled, starting with its tip. It takes 130 truck loads to haul the crane.

But first, some context. Here is a video about the trusses it raised for the new Atlantic Falcon's stadium. It makes me glad that I did not work in an industry that started each day with a "hay-ra-ra be safe" meeting. I hate meetings where everyone already knows what is being said. Where you can practically predict the next platitude that is coming out of the guys mouth. This time-lapse video is more interesting.

31000 aux tip, good for 220t!
Dustin McGovney All that line laying in the mud...
Roy Walters I hauled that Tip that went to Korea 3 years ago. When I was called to ask if I'd haul the boom tip to Houston to load on a ship, I laughed, & said we don't haul boom section!! Then they told me what it was, I'd show you a pic on my trl but lost 40 pics in a old phone. The 31000 is beyond huge!
[The line pull is 55 ton.]
Iron Jim commented on the above posting
Tony Reis posted six photos with the comment: "She's coming apart." It will take 120 truckloads to haul the crane to the storage yard. The booms come apart in lengths that fit on regular length flatbed trucks.  And each counterweight is a smallish, albeit heavy, truckload. It looks like the parts for the booms and the counterweights are on their way.

1: But this crane is so big that even the boom parts are tall and wide.
 Note that in the distance a yellow crane is holding a detached piece of the boom. And the people look like ants. It looks like the boom is twice as high as a man and three times wide. 12x18 feet is certainly and oversize width. And if they don't have some sort of well flatbed trailer, 12' can be an oversize height.
2: Now they are down to disassembling the "guts."
3: again, notice how the yellow crane is helping to take pieces off the 31000

Tony Reis 15 shifts and over 130 loads it is done!

Brandon Storie has an album of 235 photos of the 31000's first job from assembly, to building, to disassembly. One tidbit I picked up from the picture comments is that the ring on the crawler platform is 40 feet. Include some overviews below to provide some context.

Buid is finished and the booms have been raised.

Here is a better view of that 668.7 ton roof truss module. I wonder how many truck loads of parts are needed to assemble a module.

Her first big lift!

Operators read out shows VPC (Variable Position Control) is extended 75 feet to balance 680.4 tons at 1345 feet. Another comment indicated 924 tons of counterweight has been installed.
This photo sequence posted by Ray Little shows some different pieces and how they fit on a flatbed trailer.

The 31000 in Korea must have done its job and now it is for sale. I'm including all 27 images because I'm not sure the link is permanent. And because it shows it was building a plant and not a stadium.

Thank goodness for the mute button:

David Kinder posted seven photos. According to the comments, this is the one that was in South Korea or Vietnam. It is now in pieces in a Texas yard and for sale for $22 million. I think the other one that was built is still in pieces in an Atlanta yard. Like the Airbus 380, companies kept building their product line bigger until they built them too big to be economical.

Ray Little posted 30 photos of the Atlanta disassembly and a link to a video about the 31000.

An article that talks about this and other large cranes.

Ben Stalvey posted six photos. The posting has a lot of interesting comments so it is worth clicking the link and seeing if you can see it in a closed group.
