Cranes with a Luffer

I've noticed that cranes with a luffer boom seem to have become more popular. In fact, sometimes the luffer is longer than the main boom. So I've moved the luffer photos here because some of the other crane postings were getting rather big. I'll add new luffer photos here. It has sections:

Erecting Precast Buildings

Rick Wilson posted two photos. Unfortunately, he didn't answer the questions about the length of the boom and, especially, of the luffer. And no one mentioned the model number.

18000 with 180 and 230 luffer I had to stretch her out to 265’
Dean Rich posted two photos. Unfortunately, none of the comments indicated what model this is. Judging by the man in the orange vest, the tracks and counterweights are big.

I commented on the second one, and Dean busted it out as a separate posting, something I have yet to figure out how to do.
Dennis DeBruler For us sidewalk superintendents, is that panel swinging out because of wind or rapid slew rate? I would think concrete would be heavy enough that it would be hard for it to swing that far out.
Dean Rich The panel is not swinging out. The crane is booming down to reach out 198' with a 30,000 lbs. Precast wall. No wind. Very much in control.
Dennis DeBruler While I'm learning, is it booming down by angling the base boom forward or angling the luffer boom down, or both?
Dean Rich The main boom is configured at 80°. You boom up and down only with the luffer boom.
Dennis DeBruler Dean Rich Thanks. I was guessing it was the luffer. The factoid about 80 degrees is also of interest.
[But if he was booming down, I would think the load would slant in instead of out, if it would slant at all. It still looks slanted to me. It must be some weird optical illusion that I can't figure out.]


This isn't precast, but the comments below showing me an example of a crane with a luffer is doing precast concrete work.
Dennis DeBruler posted
So which model is this? It is being used to build a dam between the north lobe and the rest of the Thornton Quarry so that the north lobe can keep polluted storm water out of the Chicago area rivers.
[To summarize the comments: 777 series 2 with a luffer]
Leo Bachinski What's the boom configuration
Dennis DeBruler That is what I was wondering too. It is a PR picture off the net from the link I provided above. At least they got most of the crane.

How long is the tip and base pieces for a 777 main boom? From that scale, does it have one or two boom sections? How long is a boom section?


How long are the luffer masts? It would take some trig to figure the length of the luffer.
Leo Bachinski commented on Dennis' posting

Leo Bachinski commented on Dennis' posting
Dennis DeBruler  You can see the section joints in these pictures. It looks like the main boom has three sections plus the <whatever I'm supposed to call the tapered section at the end>. Considering a boom section needs to fit on a semi-trailer, I'm guessing a section is 50'.

Man, you go downstairs for a cup of coffee and...
Peter Quinn No wind here, heavy fog and we are (somewhat) in the approach corridor for O'Hare, but I'm thinking the taller buildings around would make that moot (regardless of any OSHA regulations).
Peter Quinn posted 13 photos of it booming up in the morning for work with the comment: "Morning stretch!" In the last two photos you can see an airplane landing at O'Hare.
Brian Peterson That's a nice batch of pictures. What's the time span approx ? please...
Peter Quinn Maybe 3 minutes. It was faster than I thought it would be. For those of us that don’t work around these machines stuff like this is pretty fascinating.

The first photo in Iron Worker's Christmas Tree.

The 31000, the largest crane ever made by Manitowoc, laid out in what appears to be their test yard..


Brandon Storie's Photo Album
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.
Brandon Storie's Photo Album
Now the radius is small enough they can remove the dolly.

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.)]

Theron Stratton I have no experience with this type of crane, but I can not see how the luffer is not pulled over backwards when the load is released.
Colin Moran The jib is limited to a max angle and has backstops, also, Effective weight of the jib, block and line.
Theron Stratton I hope this is shown at max angle.
[Notice the crane is a ringer. It has to be able to reach everything with the luffer because that crane can't move. It was assembled in place.]

[It looks like in this case they move the main boom as well as the luffer. I would think the main boom would have to be more vertical to build the closer struts.]

[I wish he caught it lifting a module of truss work into place so that we could get a feel for how much truss work it lifts at a time. 600t should be quite a bit of steel. In fact, I just noticed part of a truss module being constructed in the lower-right of the photo. I wonder what company makes CC2800.]

I’ve never seen a luffing luffer tower before .... I luff it
Nathan Cook I ran 1 years ago in downtown Dallas. Certain areas I could be completely laid out and other areas (swung towards high rise buildings) had to be all the way up.
Nick ReynoldsNick is an administrator in this group. Interesting design..I assume you’re trolly never travels on that butt section that raises up and down?
Nathan Cook Nick, trolly has the capability to run the entire length of the jib.
Nick ReynoldsNick is an administrator in this group. Wow that’s crazy so what stops it when you are luffed up like that?
Nathan Cook Pressure switch hooked to a light, hand/eye coordination, skill & know better. The old school way!

Longest boom I ever assisted with assembly. M2250 with I believe was 610’ back in 2007.
Charlie Ward I agree. way to much boom. while the nyc accident several years ago was deemed operator error, I believe the accumulation of ice on the boom was a big contributor to the incident. have never seen a load chart that allowed for that additional weight.Darrold Elliott Operator did not jackknife the boom down. Which caused accident. You cannot in-line that much boom.Brent M Nelson Uh, to boom a luffer down, you have to turn the override key as you go out of chart to do so.Joe Whiting Wasn't that the one that the boom was completely covered in ice ??as well??Vincent Umstot Joe Whiting yes but that was not the reason the accident happened.Joe Whiting Vincent Umstot yeah I know I saw the video he boomed down the main ...I'm sure it did not help that's why I was asking if that was the one.. I know you can only main boom down so many degrees when you have luffer settup...I have run these several times as well.Brett Lynch I was running a drill rig in Harlem that morning and had 4 inches of ice build up on the mast of the rig in less then 20 minutes, they can blame it on whoever they want, but ice was definitely a factor! Should of left her vertical!

MLC 650/Luffer, they were setting 390000 lb. Nacelles outside of Plainview TX two years ago!
Ben StalveyBen and 4 others manage the membership, moderators, settings, and posts for Manitowoc Crane Enthusiasts. Awesome amazing crane. The death of the maxer wagons.
Jerry Spearn The VPC will never replace a maxer wagon. The VPC is way to slow. Until Mani fixes the sync and allows the operator to boom up and down with speed and not be stopped all the time making it difficult to control your load smoothly.
Don Leverbee 1. The screen will tell you if you're booming to fast, if you can't adjust your stick, its not the cranes fault, its yours. 
2. Turn the boom hoist speed down from 100% to 85%, if you can't control your speed.
3. In S-3 the VPC Max will not be out run by the boom.

4. With 300k on the hook, how fast do you want to go ?
5. If you want go fast, stay in the small cranes.

Jerry Spearn Production work requires speed. We aren't picking 300k once at 25'. We are picking 30k 100 times at 200'
Don Leverbee You would still make better time by adjusting your drum speed, vs. Getting stopped by the computer.
Play with it, maybe start at 90%.

Don Leverbee You compared the VPC to a wagon. I assumed you were running a configuration in the VPC to a rig with a wagon.
If your only picking 30k, lock the tray, your chart is reduced, but 30k aint shit.

Shane Canard I was running that crane and I could get the nacelle at 115’ radius.
Tom LaGanga 195ton nacelles?
Shane Canard commented on Tom's comment on Rich's posting
[So they lift and attache the blades one at a time.]
Rich commented on his own posting
Normally, the luffer has a wheel on its end to hold its weight as the main boom is raised from a flat position. Once the boom is vertical, then the weight is centered enough that it can raise its luffer.
