[I finally noticed the foundation with the bolts on the left side of the picture. So they are going to tilt it up, then swing it between them to place it over the foundation. It looks like the one in the foreground is going to have to travel as well as swing.]

[Abraham Lincoln bridge in Louisville, KY. Rebar cages are not strong so the rigging has to support them in many places. Note that each "junction" is a pully so the cables can move to adjust to the angle of the cage as it is lifted.]
|Morley Coote commented on the above posting|
[This is the picture that made me realize the rigging used pulleys. Note that each crane is controlling two lines (blocks). The middle blocks, in turn, have pulleys so that even more lines can be attached to the rebar cage.]

Winter is coming
Perry Silver That’s a lot a stick in the air.
Tony Snoke 370 ft
Laurent Gagnon Two bagged out all terrains to change out a blade. Haha.
Tony Snoke This was a bearing change. Every time we have exchanged blades or did bearing change we have used two 550’s.
Kenneth Ohl Corey Gerber some types of blades have to be put on one at a time because they won’t take the stress of being picked up on the hub. When you put the blades on the hub on the ground you lift the hub and blades with the primary crane. You tail one of the blades with a second crane. When you pick up on the main crane one blade is taking a great deal of weight. Some manufacturers blades can’t handle this. Also it takes a bigger crane to set the hub with the blades on it.
Corey Gerber Kenneth Ohl and maybe you should stick to playing with the RT on the jobs. It takes less crane to lift the assembled hub then the nacelle
Kenneth Ohl Some windfarms they use different size rigs for different aspects of the job. One crane sets the lower and lower mid. Another crane sets the upper mid and spike. Then it sets the nacelle. Sometimes it sets the blades and other times moves on to the next turbine. Then a smaller crane sets the hub and blades. Dont give up your day job Corey.
[They can get a way with such a long jib because the boom is almost straight up. That is, they are lifting the blade with a small radius. Lots of comments about weather or not you should get one more expensive crane to avoid tandem picks. And some photos of single and tandem blade picks.]

Uneven hoisting overloads rigging really fast.Lou Adler 2 4 points don’t always work well ...if you get the weight off could snap rigging...
Just be safe folks....Al Roskam Rigging was close to double of what was needed.Jim Browne Doesn't matter if its two cranes with 4 point pick.
Each crane is independent with its own rigging.
4 point rigging each point should be rated at half the load. With a typical 4 point lift 80% of the load is in two diagonal legs, 15% in the third for stabilization, and 5% or less in the fourth leg along for the ride.

A video of tandem lifts very little vertical clerance. Being able to move the boom in and out while under load is critical to this operation.

A video of lifting a locomotive back on its tracks. It took me a while to realize that they are lifting a locomotive behind the one we see on its side. Judging from the counterweight stack and the boom bracing, the first hydro has a large lifting capacity. Give the position of the cranes, it needs a longer radius than the other one.

This is just a lift from a barge to a storage area. To actually lift it vertically and set it in place, one of the cranes would be a lot larger.
Dennis DeBruler It is good to know that there is still at least one blast furnace left in Detroit.
Aaron Payne 2 in Detroit and 1 we built from the ground up 2008 in Dearborn. The old Rouge Steel 2 miles from Zug.
Hartley Bergeron Trent Lofton I’ve made 16-18 crane lifts. All done by radio. With spotters to ensure everything and everyone is level. Setting decks like these pictures and setting tops of jackets. Weight indicator has to work properly. I remember the days of an old Martin Decker !!
Michael Tregre Everything needs to be set up. Mats ect. Radios. Pick and walk and set. Cranes weren't big enough to handle loads back then like today. We talking 35 to 40 yrs ago.
Derek Raymond This was a whole different era, the cranes were at max capacity.As long as the track was flat we went with it and yes you had to watch out for your brother operator on these lifts.

Here's what a lift plan looks like.
Thomas Goralczyk Trent Lofton we went up to 18 cranes for one lift on this job, it was an off shore production platform for natural gas.
|Hartley Bergeron commented on Carlos' post, cropped|
We had an old school engineer who knew how to tell what crane needed to be where to bare what weight. Then you have the weight indicator on each crane to aid you to
Keep you at your weight. People off in the distance to ensure that it was lifted level. We used to points of the compass as a judge. Say they would all stop us. Every crane operator ensured we had our weight. Then they’ll say the north side is low. Or southwest corner is low. Etc. we’d get level then go higher. It was a lil hairy sometimes. But we did it.

New England Erecting Co. uses 2 truck & a crawler crane (a Link-Belt, a Bay City and a Manitowoc) to set steel beams on the construction of the John F. Fitzgearld Express Way in Boston, MA. July 1954. (Paul Joyce collection). Thanks Ray Darling. Repost from another group
Reuben Zimmer Bay city cranes was purchased by Manitowoc late 60’s or early 70’s
Bill Hough That Manitowoc looks like a 2000
J. Mike Poupore Maybe 3000 (50 ton)?The boom looks to heavy for a 2000, plus the load distribution of the three cranes it doesn’t seem that a 2000 (25 ton) would carry most of the load.Lynn Spriggs Talk about crane operators!

21000, 400 tons
John Schilberg What does that team look like? What's the org chart look like for a lift like that? Leaders, observers, operators, telemetry analyzers???Ray Little Impressive lift. I imagine the lift required a longer reach than one crane could handle, one end to come in different from the other or rigging too wide or tall for a single crane lift. I say this because 400 tons isn’t all that much for a 21000 in Maxer.Rod Walters Ray Little you are so correct, but when you need to bring one end down or rotate a bit and a tag line or come-a-long just want do it two cranes will.Ray Little Rod Walters that’s exactly what I meant in my explanation.

Rodney Thibodeaux 4000s one 3950 that's the blue crane I was on that lift in the crane with white tip that was around the early 80s reason for that many cranes is because of flex in deck and when setting in place you may have to lift a certain area to clear something out the way this pick was from the ground and we walked over.
Rodney Thibodeaux This was taken in houma, la,in delta fabrication yard which is no longer in Business the yard is now gulf island fabrication was there since the beginning retired now.
Rodney Thibodeaux We had bigger platform decks that ,we had some with 12 4000s and 2 4100s.
Hartley Bergeron Rodney Thibodeaux (tracker). After you left the decks got bigger and taller. 16 crane lifts were the norm. 8 triple 8’s. 2 M 250’s 4 2250 2 with and 2 without Maxer attachments. @
2 999’s. Higher. Taller. And bigger. Then the bottom fell out now nothing. They build boats. Imagine that. Boats. 20+years I had with them. Left and went overseas. Learned a lot from Rigger man. And everyone else. People today have no idea the lifts we made.....
Rodney Thibodeaux Notice you'll talking about mats ,we didn't need mats in this yard, we put 3 feet of layer limestone of different sizes, with mating sawed together under the stone, we put them cranes on the toes wouldn't sink now on our other fab yard that across the channel, which would be on left of picture has the same amount of stone and you need mats most places.

Jim Ball Any of you fab yard hands know what happened to the Demag CC-4000 (880-ton) crawler that Bechtel bought for the Chevron Richmond (CA) refinery job back in the mid-80s? When that job finished up, we quoted that crane to the Houston area, Louisiana - all the big fab yards, plus Hyundai to South Korea. There were big plans for it to work on the nuclear side, but we all know that went in the toilet, along with my career in late 86.
Carlos Garcia Jim Ball that crane was bought by GULF MARINE FAB for there yard in Texas in 1999 the lower unit caught fire and melted the gantry cable and the boom and mass came down it had 300 feet of main boom it was sold to a Mexican crane company they shipped to there yard in Mexico and refurbished.
Rodney Thibodeaux Had that many cranes due to flex in deck section ,and not to overload any crane ,because ground condition was not too level when tracking it throws a load on crane going over small hills ,I was on this lift ,operated the 4000 with white tip.

A more typical type of construction, laying box-section beams lengthwise onto piers, using two M-1200 ringers, the 900-ton 75A and 1430-ton 72-A. This was the only tandem pick I saw; the others were performed by a single crane. Maybe the wind that day required a second hook just to keep the load from turning on the block; it certainly wasn't excess weight or radius. It gets pretty windy in the middle of the river and the long box-section beams probably make a good sail...
Andre Mylocopos This may be the only tandem-pick by two M-1200’s ever and almost certainly the only one for two barge-mounted M-1200’s!

Zach Hurt when you make a tandem pick like that how do u calculate what each crane is good for? sorry if it seems like a dumb question...
Rory Carver Zach Hurt Both operators stay in touch with EVERY MOVE that their making and NEVER do anything before they are told...That load must always be equal on both rigs.....
Ryan Weinkauf Zach Hurt I’ve done tandem picks with cranes disproportion meaning my rig was good for 110ton and the other crane was good for 350ton. In any tandem pick it is considered a critical lift. Should be engineered lift at this point. We used walker talkies and no one did anything that the signal person didn’t say. Let the engineers tell you were to rig up. But if you are the small crane make sure your rig is the furthest from the center of gravity just as a double check on your own. (Old hand taught me that one) Humans make mistakes all the time especially engineers.

Dennis DeBruler And some of us have no intention of ever getting in a crane. But that doesn't mean that we don't want to learn more about cranes. I appreciate the question and the informative responses. At first I could not figure out how this pick was supposed to work because both cranes were on the right side of the building. Then I realized that the MLC 300 has most of the load and that the yellow crane has just enough load that it can keep the truss level and twisted at the correct angle during the lift. In other words, the yellow crane replaces guys pulling on ropes.

18000 x 4 Hard Rock Stadium, Miami Gardens FL
Chris Mentonis Alex Gritz it was the north side truss of the roof of the renovated stadium. It weighed an excess of just 1.25 million tons!!!!!
hris Mentonis Danny West each crane was maxing out at their operating radius of 35 feet at 360,000 lbs. That was a typo before I meant 1.25 million pounds not tons. Which is very possible and if u didn’t notice each 18000 has a maxer attached for extra lifting capacity.
