- Assembling a 400T mobile hydraulic crane with a 184 ft. luffing jib, which required closing down a city block of Post Street in San Francisco, on a rainy day. This large mobile crane will be used to disassemble Tower Crane #2, which is shown in a later video: • Disassembly of a tower...
Unlike most videos on this channel, this one contains a mixture of narration and music. But if you don't want to hear me rambling on, feel free to turn down the volume and listen to your own music! I don't have any great knowledge of cranes, so my narration isn't anything deeply technical or anything like that.
Sadly, I had a possible rooftop location at one end of the street that would have yielded good views, but unfortunately it fell through at the last minute. Then, I had another possible rooftop location at the other end of the street, but it too fell through. So, I had to do the best I could from the public area of a building beside the crane, as well as some shots from the street.
From Ⓗ series Week 145 (mostly April 6, 2017, a little bit on April 5).

Really enjoying your commentary on this lmao!! I work in conjunction with cranes, drawing out the traffic plans and applying for permits.
You are correct when it comes to paying the city; not sure which city this is in but in Vancouver you pay a fee for each lane occupied per 12hrs of occupancy, as well as paying the city for all the parking meters affected as if they would be utilized fully throughout. The city permit fees can be RIDICULOUS. Thanks for sharing!!!!!
Lots of fun to watch thank you HC. Especially liked at the end seeing the now so familiar view of the whole building, when the LTM 1400-7.1 got up for a test stretch of its luffing jib. Kind of heroic actually.
Thanks, Martha! When that crane reared up, it kinda reminded me of a big dinosaur with spiked back, or something...
Thanks for upload, please dont worry about music or filling the silence, you can talk whenever you want or whatever relevant to the topic. Ever since my childhood I just been fascinated by heavy machinery, excavator or cranes I dont know why but I dont get tired of watching them.
Same here friend!
You've done a few things I really appreciate, real time action not compressed, cool jazz with sax, decent narration. You may not know much about cranes but you got he parts I'm interested in, like how they go together without the workers looking like demented ants. Narration and shots that explain a lot (believe it or not) and explaining where you're shooting from and why. And the Jazz!! Yes. Subscribing.
Thank you very much, I appreciate it. I am working on a video of the use this crane to take down the tower crane. It will be done someday, not sure when...
Instablaster.
holy shit they have a crane putting together a crane just to take down another crane lol
Thanks a lot for this video! I have always been fascinated by these huge gigantic crane assembly! Keep up the good work, pal!
Thanks!
Good morning! All of the construction and rain going on looks like a typical day in Seattle lately.
This has definitely been a rainy season for SF, for the first time in many years.
The wheels on the end of the lattice boom section are there to allow that section to rest on the ground while they lift the main boom to a high enough angle so it can support the weight of the lattice boom. At such a low angle there is too much weight to lift straight out from the center of the crane. As the main boom is raised, the end of the lattice remains on the wheels, but moves closer to the crane. Once the telescoping portion of the boom (you are correct with that term) is pointing up high enough, it can then lift the lattice section without the wheels. It all has to do with leverage.
Great choice of music 🎵like watching English cartoons no dialogue or pink panther😎otherwise great video
FYI ....the "ears" are a SuperLift attachemnt to help support the point jib assembly (and the Counterweights don't hold the crane down....they "Counter-balance" it)
Been in the construction business for 35 years all over the world on projects and crane crews all ways the same, great guys always good for a laugh, you should just introduce yourself and tell them what your doing most of these dudes will talk to you and tell you what they are doing. They might even let you get inducted to the site as a videographer if you talk to the crane company and stay with one of the crane crew for safety.
My limited experience is that there are lots of nice workers, but unfortunately their companies typically don't want them speaking about the construction or letting anyone onsite without official authorization (which they almost never give). The workers get in trouble if they do, and I don't want to get anyone in trouble.
I enjoyed the video and narration, thought it fascinating 👍😀
I am in country India Mumbai. I am subscribe your channel. very good shooting. I think you are professional photographer. I am work Saudi Arabia 20 year as a crane operator. like white crane.
Your narration is very beautiful. Better then music. Great work.
Best view in town, thank You Sir.
You are quite welcome!
Neat video and I really enjoyed your narration. Looking forward to the disassembly video of Tower Crane #2.
Hope to get to it soon, but not sure when it will be.
Not a bad video at all. As a guy who loves cranes and the only technical knowledge of them is from a friend who operates them and my own research, your narration isn't bad at all.
Thanks for this video and enjoyed waching it. Excellent photography also explanation
You're welcome, and glad you enjoyed it!
@@HospitalConstruction thanks
You did a very good job constructing this video - thank you!
Thanks!
Great video AND a great voice.....😃 yea pity about camera location 😟
Great video. Cranes are fascinating
Cool video and the music is nice too no complain since its interesting fun to watch . Thanks for the video again .
Just keep talking man, I don't mind because what you saying is good.
Great video. I can see the wind is blowing pretty good and pushing that tower crane around pretty good at 30:00 mins. Good call to hold off on disassembling it till next day
When I watched this the first time several weeks ago, it got me curious about the 145 weeks leading up to it, so now I've watched all those as well. I've been watching construction sites since the mid-'50s in Grand Junction, CO, and the series you've created is the most thorough treatment of a complex building project I've ever seen. Very well done! Now I've got to watch the rest of the construction up to the end.
Thank you very much for the comment!
low self esteem in your comments. just wanna let you know that is great what you do, filmimng things you and unknown people love to share for free is not something everyone would do. These videos are great, keep doing them :)
The red arms are called mega wings. It what stabilizes the boom from bending left to right. without this it can sideload the boom and damage the hill pins! The tall v arms on top is called a gantry system it luffs the jib up and down so you can gain reach 💪 and lift.
Thanks for the explanation, appreciate it
Damn talk about making entertaining an assembly disassembly of a crane lol crane Video very creative cause I work In crane business and recording isn’t fun at all hours pass before one movement is accomplished 👍
The two giant pieces you were trying to figure out the name for our called the “mega wing.”
The white crane is the support crane to build the Luffer on the red crane.
Used to do this before I got into running tower cranes. Setting up and tearing down the 550 ton mobile!
Thanks for the info!
Great video, thank you.
You're welcome!
Tower cranes are left free so the wind actually blows the crane around and it will usually stay pointed in direction of wind. Which is called "wind vane". Hydraulic cranes cannot do this so they have to be "dogged" or put away completely while no in use.
I'm in the crane business in Chicago Mike. If you want me to explain some technical issues just respond to me.
wow - a crane to assemble a crane to dis-assemble a crane!
Thanks for the video, great to see these cranes put together, dont mind your commonalty, nice to hear some Danny Adler, cool man,
Thanks!
You did an excellent video with what space you had to work with. The crane in the foreground i operated one exactly the same for eight years and they ( link belt ), are very decent cranes to operate. The classical jazz however has a less than perfect effect on the video, but you did a great job and we can overlook the music since there is such a wonderful crane video.
Yes Loved it as I do all your Vids cant stand Jaz Music thou was Very Interesting even More so that they having to do this on a Hill I dint realize that Great Job Some of the Free Music is Nice save the Cash use that Thanks
A little crane to help build a bigger crane to take down an even bigger crane. All well in the universe 😉
...Reminds me of....Here in Sacramento, Calif....a few years ago.....Sutter Hospital construction....2 tower cranes.....one was taken down with crane nearly identical to this (Maxim Cranes).....great video, thanks....! All 3 cranes were Red of course....
nice to see Hagrid working on the assembly.
Great video, great music. Thanks, man!
You're welcome!
A great job. Thanks.
I actually was digging the music!
Cool!
So far so good. HDR from local 12 IUOE Long Beach CA
Telescope is correct.
I would like to have one of there paychecks 😂
looks like a 250 tonne or a 300, with a luff and fly on it, the v thing on top is called a super lift, it helps minimize deflection in the fly of the crane
It's an LTM 1400-7.1.
The crane super structure which has the telescoping boom is attached to the whole truck itself, it includes all the tires, what they are doing is installing a luffing jib. Boom Extension for added height and reach. To the main boom which the guy was standing on guiding the other crane operator holding the luffed boom in place to get pinned. There’s lots of pieces that all have to work together here. Yeah it’s very interesting profession. I love it.
How about "I Robot" from Allan Parsons? Haha, just kidding.
Using a crane to build a crane, to disassemble a crane.
No disguises here 😉...it is what it is.
Went is the video of the second tower taken down is coming?
i like the music
@Hospital construction, not only do they have instructions, but you should be excited to know.... they also come with "special tools" complete with their very own factory designated storage space....😯
.....and chances are, none of those guys have ever done this before either!!! 😆 🤣 😂
it is a telescoping boom and the top section is called a luffing jib
Those bars in the y shape are luffing jib supports, gives alot more muscle to the end of the boom ,at lift point,, he will be stretched way out, it will kinda resemble a spider when in the air, I've put many of them together, along with the tower cranes themselves,, after a certain height the tower builds itself, as in 2 iron workers on the rigging and it picks a vertical section from the ground and brings it up, then the iron workers take the pins out of the square frame and it jacks itself up and sucks the new piece in then lowers and pins are replaced and repeat till desired height
Great video, good job👍
the top of the boom has wheels because when this crane lifts its boom is gonna have a bit of a bend to the boom so the wheels allow the top of the boom to roll
Ah, that makes sense -- thanks for that information!
the wheels are because it doesn't have the capacity to lift the luffing jib from the ground flat, the operator would boom up his hydraulic sections while allowing the wheels to roll closer to him until he has the chart to lift the entire assembly
We never use the wheels if the jib is shorter than 56 meters. or if we are going to raise the boom from the side
elarvator music,haha,goodonya mate
Those are the mega wings. They stabilize the boom
That’s actually called the T-Y GI it’s increases the cranes lifting capacity!
Well done! (again).
What you see in this video is the assembly of a luffing jib on a Liebherr LTM 1400 7.2 telescopic boom crane, a 400 ton lifting capacity crane on a 3,5 metres flight, with a maximum telescopic hight of 60 metres, with 7 axles..
It is already quit a large crane, but there are even much larger ones..!!
The maximum lenghth of a luffing jib mounted on this crane is about 60 metres.. The maximum working highth with a luffing jib for this crane is about..140 metres..
At the very end of the luffing jib there is an top mounted with a guiding wheel to guide the crane when the boom will be lifted or be let down..
The crane is further mounted with extra hoistcables at cablerolls at the mounted platform at the vack of the crane for lifting and guiding the luffing jib up and down together with counterweights with a maximum weight of 200 tons in 2 parts of maximum 10 blocks on each side..
On the crane itself are spanners mounted wich will be hydraulicly positioned in an upright position an sideways to gide the luffing jib and provide the telescopic boom from bending..
It is always a spectaculair side to see a large telescopic crane in working because of its highth, but also to see the assamble or disassambling of such crane..!!
A crane to build a crane to disassemble a crane...
elervator music or doctors waiting room music ,very good quite relaxing ,lol. the peace they are building is called the luffing jib and you are right the boom was telescoping out
Wow nice crane and video of course :D Like it :D
I’m guessing that’s temporary outside elevators that keep going up and down at one end of the building.
them 2 Pices are Superlift or Y guides.
I`v been waiting for this!
THIS IS A LIEBHERR ...GERMAN CRANE AROUND 300 TO 400 TON HYDRAULIC MOBILE CRANE WITH A TELESCOPIC BOOM WITH A LUFFER ON IT FOR REACH...THESE ARE USED FOR REACH BECAUSE A HYDRAULIC BOOM IS VERY HEAVY AND WOULD TAKE A 1000 TON CRANE TO REACH THAT HIGH AND FAR AWAY!
Thank you very much for all of the information! You wouldn't happen to know the exact model number of this crane, would you?
It is a LTM 1400-7.1 and I actually had 184' of Luffing Jib with Y-Guy Heavy lift attached. Thank you for your video.
Thanks, Danny, thanks for checking in, good to hear from you. I'll eventually be getting to that video of the tower crane coming down...
OH...I GOT 40 YEARS IN THE SEAT OF CRANES
It is a LTM 1400/7 and the equipment is calleding luffing jibb
Imagine if they use crane 2,to build the mobile crane,to take down crane 2 lol
2 guys working on a ladder, hands in pinch points, no harness over 10 feet, no tag lines.. hope osha doesn't see this. Video was entertaining though!!
nate osha says u ain't supposed to tie off a peace of moving equipment so why are they going wear a harness, and no one uses a tag line rigging up a crane 😑
Osha says no fall protection is required for heights up to 15 feet for crane erection.
Thanks Nate the safety officer, tell me again how you’re going to safely tie off at 10 feet and not hit the ground? Stick to what you know or just shut yer hole.
Need a crane to assemble a bigger crane to take an even bigger crane down.
appreciate your videos boss
WD 40 actually takes off some oil and lubes....they need something different for lubrication
water displacement formula 40 made from fish oil
What is genius? It is the secrets of the gods revealed to man!
No one starts out working with a 400t crane.
Surprised no one is asking about harnesses for the guys working on top of the boom.
Yeah, 'it all looks like' "jazz" to me ! LOL
Thank you. Very nice
You're welcome.
I'm curious how many can still count to ten using their fingers. Tons of steels fitted with millimeter precision, absolutely incredible.
They probably dont need to use their fingers. These are the smart construction guys
Its about knowing where and where not to put your hands and fingers.. and pins for the jib have a taper, so you dont have to line them up exactly.
here in Australia, many of the people ive worked with have been injured over their 30 year careers, but not nearly as many as you would think are missing fingers. Of all people ive worked with, well over 100 only maybe 5 have lost a finger or part of one that i know of. It still surprises me doing this stuff. Lots of close calls but here they are still typing away 😅
This is a Liebherr LTM1400-7.1 for sure,and it`s worth more than 3 million dollars
hah! make thats 3x that at the least our LTM 1050's are around 3 million already
Looks like a nappy pin 😄
don't redo the commentary , the way you are talking about it is great you are speaking in simple terms .on the base of the crane its called a hydrualic boom and they dog men are connecting a lataceboom ok.
Liebherr makes the biggest most powerful cranes...They set the bar for mobile and track cranes...
There are other manufacturers that make cranes just as big and as powerful as Liebherr, but what I can tell, (been a crane driver for just over a year now,) Liebherrs are the best I've driven. And when our company orders new cranes, they go to Liebherr. Reliability, ease of use, ease of maintenance etc. are just superb compared to the competition. They do though buy other brands aswell, but they are usually sold at a discount because of the original buyer didn't take the crane they had ordered for one reason or another. :)
the crane base is a telescopic boom crane
correct term is: "all terrain hydraulic truck crane".
Hospital Construction are you mainly located in the Frisco area? I'ma union ironworker from UT LU#27 n I've got in on quite a few crane gig's n sure more to come, butI've been thinkin about investing in a go pro to wear on a crane job or just the everyday steel erection cuz I'd like to have video of some of the crazy goings on I've experienced. If you'd wanna put a video together cuz I wouldn't know the first thing about doin any Tech stuff but I'm sure that's something I could do. Let me know if you're interested n will work something out

Great video, thanks for taking the time to make it and share it...and don't worry about the music it's not too bad.
Thanks!
Reminds me of my x
Those things you missed going up is the superlift supporting structure.
Whoaaa!really Big budget to do that....
I like your music
What is the name of the jazz track that you played in this video ? I really like it.
That music was licensed from here: www.audiomicro.com/blues-and-jazz-machine-town-royalty-free-stock-music-1156332
U'RE RIGHT ....THOSE THINGS ARE "WINGS"!
Their purpose is lateral boom stabilization. Controlling side loading. The design of the telematic boom has strength has the main strength in the vertical plane, and a vertical lift. When over a certain amount of boom extension and the use of a luffing attachment, lattice extension, or a load at maximum extension and weight, also they are used to stop any side loading forces or influence from load moment and wind in the left and right plane of the boom.
Thank you very much for that explanation, Ted!
29:57..."resting place"..called "DOGGED OFF"!
I turned off the audio. (thank you for the heads up). I'm sure you a are a great commentary...
THE PIECE ON THE END THAT IS MADE OF LATTICE IS CALLED A "LUFFING JIB"
Liebherr 1400. Used to put one of these together a couple times a week

I,m curies how they remove the parts of the crane build within the hospital
They actually just lift them out using the mobile crane.
I wonder why they did not use the other tower crane for the sections, as renting the LTM 1400-7.1 won't come cheap. Guess Sheedy gave them an inexpesive rate as most of their cost is setting up and taking down.
The other tower crane doesn't reach far enough to remove its companion -- they don't overlap enough to do that.
Base of crane is incased in poured concrete and will not be removed. It is a pretty big construction job in itself at the beginning of the job.
Ya the owner of the building buys and gets to keep the base section usually built on caissons or a massively reinforced footing. These leibheir tower cranes really aren't too complicated to erect tear down or jump, if you have a good crew of union ironworkers! Sometimes if they've been up for a few years in the weather, some of those pins in the tower will test your medal for sure, but that's how you weed out the Joe's. Not many men can hang outside that tower, hangin by his nuts swingin a 12lb beater for 3 hours to break one stubborn pin loose. Then the boss radios up after 3hrs n says what's wrong, do you need a pin puller? Which is a hydrolic pin puller we didn't know he had that the only effort it takes is to hold it there while it does the work will make anyone rethink his career choices. It is a very dangerous and greasy job but it's hell of an accomplishment to have a 200+' TC ready to load test in three days. Ironworkers LU#27
They attaching the luffen then they will most likely put the the job on which will give them the reach to take down the tower crane. Oh by the way that is all connected to the crane it's self.
Rambling is fine, cannot stand background music.
the poles are called Gantry's
It looks like a really Sheedy crane to me. 27:30
The chain link pieces between the sections looks like a retro fit up... But what for?!
Those are called peanuts, they are used to pin the pendant lines.
Music nice!!!
So what do you use to dissassemble mobile crane then?
Ekky Hardiyanto The big mobile cranes like this, use smaller mobile cranes.
Smaller cranes don't need anyrhing.
You use a smaller mobile crane, then a smaller one to disassemble that one. You keep using smaller cranes until you end up with a guy using a come-along.
Another crane. This one is a lattices crane 225 tons
That's what the first crane is for LOL
