They barge the bridge collapsed bridge debris to the new 10-acre laydown yard used by the U.S. Army Corps of Engineers to process wreckage from the Francis Scott Key Bridge site. An estimated 50,000 tons of concrete and steel collapsed; once removed, the wreckage is sorted and transported two miles away by barge to Sparrows Point. Debris and wreckage removal is ongoing in support of a top priority to safely and efficiently open the Fort McHenry channel.

That piece of equipment is probably ideal for the road deck portion of the recovery.
Better coverage than any news station! Keep it coming!
Thanks Jeff! Another great review. Crane operators are among the highest paid heavy equipment operators. My neighbor growing up was a crane operator. Sometimes away from home for weeks. Gotta really know your stuff, have nerves of steel and the patience of a statue. Daydreaming is not allowed. When you get the command to go up 3 inches, you better be paying attention and go up 3 inches, and not oops shoulda been the other up.
So while the impetus is on getting that channel cleared, you can't rush crane work. That's when people lose limbs, and collapse failures can cascade into existence. Slow and meticulous wins THIS race!
Looking forward to your next one!
Like fine barbecue low and slow
@@jeffostroff There you go!!! I think you are getting the hang of this incredibly meticulous and highly detailed process. Good for you!
The main span of the bridge is Suspension under the flying truss. The sonar images show many of those cables still attached to the submerged roadway. This could explain why they are moving the sections of the truss so slowly. Those cables would need to be severed before lifting the heavy steel.
He keeps pointing to E-Joints are a cause. Worked construction, was on a few bridges under con.. The way I see it is the roadway is a liability as it's no a load bearing structure. The bridge was built to support the roadway.True?
@@ch3no2killz True. That is the reason for the whole structure; to carry the roadway over the river, SAFELY.
The piece isn't pulled up because a dive team is cutting the beams below in the darkness. So to keep them diver's safe it's rigged up so it can't crash down once they cut thru the pieces near the deck of the bridge because that is what is holding down the frame.
Amazing how you have so much intel and vids of everything you cover, Great job!
I appreciate that!
Yes, Thanks! It's all publicly available, sure, but finding it & separating the wheat from the chaff & BS is time consuming WWW detective work and you've gotta know what you're looking at and what they're feeding us.
@5 mins - very possible they dicovered the last missing worker and everything would have ground to a halt until the body is recovered. Or something else entirely...
No they tried to lift it the day before too, and had problems.
@@jeffostroffi wonder if it’s hung up on something, or maybe off-balance (being an odd shape(?)
Could still be attached underwater. Crane just stabilizing it while cutting underwater
Not likely
Yes my assumption too.
Thank you for keeping us up to date on things. It's tragic that people had to die, but maybe the next bridge can be built to better withstand the marine traffic issues that arise.
Thanks for coming back for more videos Deborah!
@@tedanderson463 I'll have to look up some of those other bridges. I only knew about Galloping Gertie. What a horror that must have been to witness her collapse in person. ☮️
pretty ignorant comment considering ships werent the size they are now when the bridge built 50+ years ago.
Thank you for the updates
A word of acknowledgment was missed in the showing removal of these large sections of bridge , this being " look at the chains that are attached to the damaged sections " Underwater divers have to maneuver these enormous chains to a proper fastening / balance point . Great commentary and following of the clean up
That claw was used during the Catharina gulf cleanup where multiple unused offshore rigs collapsed. It can to some extent crush the structure and in some cases also cut, but realy rely on divers with cutters to chop up the pieces. Good thing is that it doesn't need to be 100% aligned on top of the load to pick it up as long as the two sides of the claw can gap over the structure.
It’s better to call it counterweight, rather than ballast.
Grab looks like it has the hydraulics to crush a bunch of stuff
@@mmmartin261 barge people call it ballast

The Chesapeake 1000 used to be the sun 800 (at the sun shipyard in pa,).
Traveling with load can be dangerous.
Tubular booms are strongest. But susceptable to damage.
Ie. On P&H 90T TRUCK CRANE
a dimple in a boom member bigger than (can't remember exactly) but the size of a nickle or dime effects the structural integrity of the boom. And replacing the damaged strut is required.
Ex philly shipyard crane maint.
I enjoy your commentary and videos on this incident. It brings back memories loved that job!
Wish i was 30 again.
I know nothing of construction but I love Jeff’s videos. Great voice. Very intelligent.
Thank you for the updates. Cheers.
You bet
Another great video Jeff, your work is greatly appreciated. Very professional in your reporting. Something you don't see much these days. From cleaning this up, to rebuilding this bridge is going to be massive.
One of the most interesting RUclips videos on cranework is " Dizzying View: World Trade Center Spire Installed". The operator was way up on an un-braced tower, note the sway as the load nears the top. The connectors were a rowdy bunch, but very competent.
This is all an amazing witness to seeing what it takes to clean up all this mess. That massive "grab" machine is awesome! Thank you for your excellent coverage, and peaceful way of explaining everything for we who are interested in all thus!!!😊😊😊😊😊😊😊
Tanka Diane glad to help!
I just keep thinking back to the Big Blue crane collapse in Milwaukee in 1999, and I'm sure these operators have the same thoughts. That incident rally added emphasis to the movement to certify crane operators on specific types, lifts, and loads, and that kept me busy as an instructor for quite a while.
-it was too windy that day.
its why they are only doing 200-400 ton picks with a 1000 capacity ton crane. big blue they were running everything right on the edge of the max and the wind load took it over
@@imchris5000 Exactly, but running up to the edge when there are uncontrollable variables such as wind will eventually catch up to you. I personally feel that in this age of computers and calculators, instead of slide rules (remember those), no one is throwing in that 10% here and there that helps offset those edges. 2 + 2 = 4, but some folks feel that 2 + 2 = 4.000000 is more accurate.
Thanks for the coverage
My goodness, can you imagine the hydraulic system needed to operate that claw!!!
New sub been watching your clean up coverage vids man your a smart guy great content !
Jeff another great update. Thank you for all the hard work to get us these videos. Any word at all in the last two fallen workers. I eggs they would come back hone fir the staff their family’s and the world can have peace if there is such a thing in this mess. Just to know they are out of the water will be such a relief. Tfs
the grab is for the floor sections
Back in the day i worked for a company that made grapples. Some two tine, three tine and four tine grapples. We didn't use the term claw back then. Just adding some useless info here from my old world. Everything from me is 'back in the day"
It's a GRAPPLE and not a shear. The lightest steel is at the top. The lower you go, the heavier the steel. And...visibility and working conditions for rigging and cutting are a completely different world. The concrete and asphalt deck is a different animal as well. The optics are overrated as too how quickly the progress is going.
It could be that the crane is used to put tension on steel parts that are still underwater. Salvage crews could be cutting parts of the collapsed bridge underwater.
Hurty‼️
The Kids need the
Claw for the machine back. There’s a

In there‼️
truck probably used to increase GPS accuracy. By knowing it's position precisely, accuracy of other GPS in the harbour increases
Those tug boats are incredible!
jeff, how and where do you get the live video?
When everyone was panicking, I said.. "The Army Corps of Engineers don't mess around. They'll have shipping lanes open in days....not weeks."....Awesome US Army does it again 👍💯
With regard to the shot of the C1000 attached but not moving.
I suspect its caught on something and the crane has reached its lifting limit.
It looks like the barge’s deck is parallel with the water. That would indicate a full load on the hook.
I ran some calculations and came up with 17’ of draft, even keel with 1000ST @ 63’ from the bow.
You shot seems to show the stern lifting as rope is taken in. 🤓
Just to show some of the guesstimates I’ve used.
Using midships as a datum, I am assuming 3500T water ballast @ 50’ aft of datum. FW TPI = 44.8T
O the wonders of steel
Great content
We like your key bridge projects. Nice jobs!
We were Crane Following IT was a rewarding job .. it's always Impressive to us How Crane Crews make Dangerous work LOOK easy and Fun ...I enjoyed my job a fun Crew to work with .....Wow that alone can make a jobzfun too😊😊😊😊😊😊😊❤❤❤❤❤❤❤......It's be exciting to watch your "SHOWS"
Wow that claw thing is huge.
Jeff I laugh every time I hear you mention the machinery munching through, and it gets hungry lol😆
Are they going to send for the VB10000? It's got a 6,500 ton lifting capability and was used on the MV Golden Ray.
Thank you for the updates, Jeff! Very interesting they haven't used the Chesapeake 1000 yet. What's up with the new ratio for this video? I like it but it was just, sudden
Some videos come in different ratios by unified command
Awesome footage Jeff, So .... What do you figure the time line is, ( After forensics has done due-diligence ), for enough of the structural steel removal and your port is okayed by NTSB and the harbor-master, that you folk will be up and running again, say at 50 % or better??? . Lie to me if you have to. lol . I'm just asking from a power engineers POV , not anything that might be note-worthy....... I am figuring on July....
Any way, Nuff said...... Stay Safe
Unified command says end of may
Good report. Please stop the FIU mention. It's getting tired.
Counterpoint: Jeff is a creator and new people almost certainly come across his videos all the time. So, it's good for him to advertise other related videos, e.g., another bridge collapse.
Perhaps he could alternate mentions of other video series such as the Champlain Towers South building collapse, but I suppose some people would get tired of that as well.
of course is Not boring. He is proud of his work... And I'm sure he has no ears for your negativity. 🤷
That big mechanical lobster sure is an impressive thing
Make sure you include the date when you mention a day just in case we're watching the video days later. That will help make your video more Evergreen
Like that Howard Hughes ship to bring up that Russian Sub
Project Azorian a U.S. Central Intelligence Agency (CIA) project to recover the sunken Soviet submarine K-129 from the Pacific Ocean floor in 1974 using the purpose-built ship Hughes Glomar Explorer. The ship ended up in a Chinese scrap yard in 2015.
Is the VB10000 coming to provide support
No, the grabber can not cut metal. I live close to where they keep it.
You have to worry about the load flipping over the way they had it rigged.about time for the big clam bucket. Lake Erie dredge and dock has one of the biggest clam buckets. Aside from this 200 toner
Will be able to get the roadway parts
That crane was probably stabilizing the section
3:42 the camera was set to auto focus. A photographer would know to set the focus manually . IMHO this was a low light image and needed a tripod and a faster lense for a slightly longer exposure😊
Jeff, I felt like I was in the matrix, did the video duplicate from 5:10 to 5:35 ish. Just curious?
I agree if they found a worker all work would shut down.
After living in the state of Florida, I know they shut down major highways when an accident deals with a death for hours.😮
Thank you
I think I re-used a piece, was trying to show difference between 5pm and 7pm
@@jeffostroff I was really hoping to find Keanu Reeves in there!
I heard it too, I was like, wait, I just heard these exact words..! 🤔😵💫
That steel was in great condition. I wonder if it came out of Sparrow's point when it still had a melt shop.
there will be more 1000+ cranes coming in the next few days it takes about 20-30 days to move from the gulf up the coast which is where most of the super heavy floating cranes are in the usa
When the barge with the bridge truss was sitting for hours with the hanging piece, they were probably thinking about where and how they wanted to secure the piece of bridge truss maybe.
They should bring in an army of YT magnet fishermen to help in the cleanup. They could all make videos for their channels while they work.
Is there anything left of the old Bethlehem Steel plant in Sparrows Point?
No. It's now called Trade Point Atlantic, and it's a Amazon, VW, BMW, Home Depot, and other giant distribution centers. I commuted over the Key bridge for 28 years, and watched them dismantle Beth Steel day by day. At one time, is was the largest steel mill in the world.
OOOOHHHH The Claw!!!!
Say Jeff, any educated guess if they will take the remainder of the standing bridge totally down or could they still use some of what is left.....
It took two decades to build this bridge. I imagine you can't remove all the parts over night. What a big job. The construction of the bridge and its approaches completed the two-decade effort to build I-695, although the bridge roadway was officially a state road: the unsigned Maryland Route 695.
The worst part was that BETHLEHEM STEEL vigorously fought against the APPROACH highway going directly THROUGH their sprawling 3,300 acre property. The largest individual steel mill east of the Mississippi River! So they had to ELEVATE the entire access rode way across the steel mill to the bridge. Such a HASSLE. Then slowly overtime, as the steel mill waned, there WERE at grade access rode ways to the bridge. Dreadful history indeed.
Sam, Towson, MD
No modern day bridge, takes 20 yrs to build !
@@andrewrees8749 that’s true. That reference is to the very. Protracted battle between the MDOT and Bethlehem Steel over ACCESS highways to the bridge. As you see in the recycle process, the former Steel Mill grounds (3,300 sq Ft) dominates the shoreline. The Steel Mill did NOT want “at grade” access Highways ON THEIR GROUNDS. So it took “20 years” before they settled on ELEVATED access highways. All of this history is almost 60 years ago. And became a moot issue with the closure (and demolition) of the Steel Mill. I hope this explanation helps clarify the situation.
@@andrewrees8749 Addressing the “20 years to build the bridge” wise crack local comment: This is an exaggeration borne of the numerous frustrating delays. It DID take FAR TOO LONG because of the unfortunate hassling over highway access and funding cycles. But you are correct, for as long as it took, it probably didn’t quite take a full two decades. It just seemed like it did!🥱
It be so Cool cool if You And "WHATS GOING ON WITH SHIPPING ",,you tube Channel Both would Team together.. You both DO a very good Job. WHEN YOU TWO TALK you both make a hard job Exciting and Fun 😊😊😊😊😅😅😅❤❤❤❤❤❤
In the Bay, the watermen tong for oysters. This is a giant oyster tong! 😊
It's in this ballest position so the bow is high enough that the load is high while keeping the hook from being in danger of hitting the boom while at rhe same time the load is high enough to sit onto the dock
Jeff
Good video to watch, but don't need the drama. thanks
WOW !!!
The MV Golden Ray was a ship, not “a boat” ! Incidentally it capsized on its way to the port of Baltimore.
The grapple doesn’t have any cutting ability per se, but it may separate some sections by gripping weaker bridge members that might rip free from the rest of the adjacent structure. Either way, it will get the job done.
Do we know what crane is going to be using this huge grapple? I’m thinking you would require a revolving crane, like a large crawler crane secured to a barge. Capacity of the crane would probably need to be around 700 short tons minimum. I’m aware that the grapple capacity is 1,,000 metric tons, so I suppose it would be logical to try to match the two pieces of equipment. So a 1,000 metric ton crawler crane would be a solid choice. But of course there are many factors in obtaining and mobilizing this type of equipment. Lots of logistics challenges involved.
Not problems JEFF!!! They are Standing it up VERTICALLY to allow UNDERWATER cutting from entangled submerged structural elements.
ADDENDUM: please click the Governor’s Press Conference TODAY and learn that my “standing up” to cut below the water assertion is CORRECT per the Corp of Engineers!
Mr Jeff, how many crates are on the Dali? What percentage are reefers? Like your input,pics etc. Keep the badboysgirls away, so you can keep it up.
My guess is that it isnt for cutting stuff apart because it doesn't have any cutting edges.
But, dang, those cylinders are huge.
What they really could use is a maritime oil field heavy lifting crane as have seen them rated at 15,000 tons and now have some even heavier rated. Most likely all of those cranes a good distance away and also under contract somewhere. Delays could have been from the search for missing bodies ongoing or underwater entanglements with bridge roadway debris.
Problem is the draft of the crane exceeds the depth of the water.
That 200t grab - fine. But - what crane will it attach to?
For me the sad thing ist the lack of crane capacity. Most cranes I saw are mobile cranes placed on barges. These are very problematic: Their stability depends on a stable ground - not given by a barge.
Mobile crane or crawler cranes? A stable pad and must be plumb level to operate at near capacity.
@@leonardcollings7389 As far as I saw both. Perhaps now the mobile cranes are gone. But lately I saw crawler cranes a lot. But they also need a stable ground or can only operated by a fraction of their capacity.
@@wjhann4836 The lift capacity measurement of a crane tells us how much load a crane can lift naturally, including the dimension of the load, lift height, and lift angle. Crane comes with a load chart.
@@leonardcollings7389 Well the capacity of mobile and crawler cranes is not significant here. Those cranes need a stable ground since they have a very limited ground space - hence lack of stability. I would estimate they carry 1/10th of their capacity at best when operating from a barge.
If you have doubts: Look for "alphen aan den rijn kranunfall".
Key Bridge
🙏🙏🙏
your timeline is off. that piece on chessie wasn't on there for 2 days
lol You know that Amazon delivery guy's going to be pissed If he has to drag that Grab from his van your door
Amazon Prime too!
@@jeffostroff lol Next Day delivery 😁
Very nice thumbnail indeed.
For some reason, the jaws on that claw kina reminds me of my X. How it looks and because its called a savage grab. 🤔
DooooooooH
Can you imagine the crane game that came out of
Yeah man watch out for those swinging LOADS.
As for the salvage grab picking 20 cars. It most likely crushed all of them & probably could have picked more
This "big help" clamp at most is an old piece for an exhibition. If you haven´t noticed, it is welded to that barge with steel tubes permanently.
The tugs are busy as bees and will be for quite a while until all this debris is gone.
I love tugs....so strong and feisty!
We can see electric lines very close to the cranes...
Maybe the truss is being cut underwater and supporting it so it doesn't fall on the divers.
Imagine the shipping cost on something like that if you bought one off Amazon.. Hypothetically of course
Could you please date your posting, many times I log on and find out the posting is three days old. Thanks
That is a GRAPPLE.
Everyone has their own name of rit. T&T Salvage who owns it calls it a salvage grab
@@jeffostroff OK nice.
@jeffostroff Sometimes, different industries will call the same thing by different names. So that got me wondering if the maritime salvage calls it a grab where others will call it a grapple? I find this stuff interesting because if you know that a specific industry calls something a particular name, when a person uses that name, you can guess what they do.
Pictures are blurry because of the FBI truck.
Bigger is better!
Humungous is such a ridiculous word. What makes it better than huge? Nothing.
I will take one claw please send it to me thanks!
I don't believe there is but one grapple like that in the world.
Azorian says "Hold my beer..."
Can I assume that you are using an ENGINEERED laminate wood product?😁
Of course the claw is from Galveston, should have known from how rusty it is. Everything rust so fast here.
"I gotta see what these things sell for on Amazon." uhhh ... Jeff ... can we talk ?
This is s grapple not a shear
