Manitowoc's 4600 Stinger, 7000, 18000 and 21000

By hinging the boom on a crawler ahead of the body, they can use the body as a counterweight.

They had a 4100 version of this "stinger" design was well. Ken Wright posted five pictures with the comment: "Lampson Crane that Unloaded me July 2014 New Town, ND."

4600 quick change. She was a beast!! I ran this one at BASF in Freeport, Texas back in 94-95 . 28 part block and no power down! Less than 15-20 tons was free fall with air brakes! Set all towers, reactors and other major lifts with this machine. Lots of crane mats involved working this machine! One of B&R's Manitowoc 4600 with counter weight modifications, 4600 mast and Lampson boom and crawler out front.

The Manitowoc 7000 was another crawler-crane design that put more space between the boom and the counter weights. It is basically a ringer-crane on tracks.

Ben Stalvey The lower could be used as a transporter as well.Aaron Adams How many tons is the 7000 good for at max?
Ben Stalvey 800 tons
Victor Hurst I was told that they only built like 5 of those crane?

Same crane with upper.

Here is the big Manitowoc and now just 31000

Manitowoc 18000 and 21000 is another solution for achieving the stable base of a ringer crane with the mobility of a crawler crane. This video provides an overview.



And this is a closeup of the "counterweight wagon" called a "Maxer."

What is it?
Greg Scher That's the counterweight wagon from a 18000/21000 -- the same wagon is used on both rigs.Greg Scher That wagon is set at the 50-foot radius swing. I have the same wagon on my 21000 right now. I have 245-feet of luffer in mine at the moment.

Yeeee haaaa
Jason Irwin Looks like he's already boomed all the way up too.
[This is why they invented diferrent ways to increase the distance (leverage) between the boom hinge and the counter weight tray. It was evidently lifting the nacelle of a windmill with too much wind.]
Don Luebesmier posted
Start adding the boom tomorrow !
[Reading the comments, this is a MLC 650 with Max-VPC. VPC is variable position control, which means a computer will automatically move the stack of counterweights along the rail as the boom moves to keep the unit balanced. Since they don't have much boom weight installed, note how the counterweight tray is moved all the way towards the center. As they add boom weight, I expect they will roll the counterweights away from the center. I just noticed that they are still adding counterweights to the stack. Each counterweight is "22k." It took 32-36 truckloads to bring the parts. Just a 301' main to pick 210 tons at 120'.]

This image shocked me because it can hold its boom+luffer is long and it can hold it horizontally.

Ben Stalvey 888 Ringer pretty rare
[
A .pdf file about a Chicago project that used a 888 Ringer on a barge The barge itself was interesting (It is interesting that a barge company has a location in Fort Wayne, IN (my hometown). There is no barge access to that town. Then I noticed that their big deal is that they can build a barge from modules that can be trucked.)]
Normally, the luffer has a wheel on its end to hold its weight as the main boom is raised. Once the boom is vertical, then the weight is centered enough that it can raise its luffer.

MLC 300 in Maui
Just a few hours after I came across the .pdf in the caption above for Al Easton's posting, I came across this posting. Aaron Parker posted two photos with the comment: "Triple 888 in a ring on a barge on the Chicago river a few years back."

Here is an example of the dolly needed to help raise the luffer on a 31000 even though the maximum counterweights of 1,848,000# has been installed.

Now the radius is small enough they can remove the dolly.

[Ben called this a "hanging tray" setup and said they were rare. Other comments indicate they were rare because "counterweight wagon" was a better solution.]
Ben Stalvey posted
Mike Larson thanks for this awesome picture. Equipped with 180 foot of main boom and 220ft of luffing jib. This 21000 with maxer placed this 314,000lb load with rigging 125 ft up. The 21000 is Manitowocs second largest crane with a capacity of 1,000 tons with maxer.
[And here is an example of the 21000 with a wagon.]

Two 16000s on barges with 60-foot rings. One is owned by the US Army Corps of Engineering and is called Hercules. The other is an ex-Lampson platform ringer and has been working at the Olmsted Dam for 10 years.

Ben Stalvey posted two photos with the comment: "USACE Crane Hercules and the Ex Lampson Platform Ringer. Look at the setup of the back mast in the rear of both. They sure don't seem to be the same machines."

Tom Burkart The red rigs back mast is completely different. It was built to be lowered for bridges on the Mississippi River. It is self erecting. I believe we only built one with that setup.


Carl Dodge comment on Ben Stalvey posting
This the same crane testing with about a 104,000 pounds at about 190ft radius off the jib.
[How do they keep the barge from listing with these two cranes?]

Ben Stalvey 18000 680 ton craneBen Stalvey If you put a maxer wagon on her she will lift 825 tonsRobert Burbridge This is the workhorse. The MLC doesn't have the reliability.Ben Stalvey Alot issues with the new MLC?Robert Burbridge From what I have dealt with, is the tray losing calibration, all the updates, 6 software updates, oil leaks, etc. It's not a machine that doesn't make you nervous anytime it's working. This is only my first hand knowledge. But they are trying to resolve the problems.
Nick Magnotta commented on the above posting
This is probably not a Manitowoc, but it is of a comparable design. One comment noted that the high pile of counterweights had not been moved backwards while holding the load.

Screenshot
One advantage of today's phones being able to take videos is that we have multiple views of this accident. This view clearly shows that the problem was not the ground giving away because it was backing up when it tilted forward. It was probably a mismanagement of the extension of the high pile of counterweights. Note the back counterweights become part of the problem as they are free to swing forward. Fortunately, it tilted slowly enough that the men were able to run out of the way of the falling load and boom.

Ben Stalvey commented on his posting
[Back when it made its cranes on the peninsula, it could easily ship is big ringer crawlers using a boat. (Probably on a boat it made because they started as a boat company and became a crane company.)]

Posted by Kevin Coffman        Kirk Sawberger Terry Hill they were rated 600 tons if I remember correctly
The ground must be very hard because they are not using any mats. Then it occurred to me this is a yard were they make oil rigs, not a general construction site. So yes, they maintain a hard ground.

Not my pic .. 21000 going up in South Texas .. from big to small it's all physics..pulleys and triangles...
Earl Click Sheaves dude not pulleys.William Platou I get it, in crane language its sheaves; in physics its pulleys-its true a crane is triangles either compression or de-compression..Gary Fox A 21,000 is going together at Ottumwa IA. Parts started arriving last week.

It seems that can configure about any type of crane as a ringer. This one illustrates how they can pile a lot of counterweights on a ringer since they are directly supported by the ringer rail.

[Unfortunately, none of the comments asked about the location. One reason for following crane groups is to learn about new bridges that are being built.]
