Cranes are the backbone of construction projects. So why do so many of them fall down?
Because they are so pervasive and they do such a dangerous job of lifting massive objects high into the air, occasionally cranes fail. In this video, I want to walk through some of the reasons these failures occur, using historical events as case studies.

Every time I see a video of a lattice boom or extending boom crane tipping and falling…(except for the failure of the ground under outriggers)….my first thought is…"Suddenly, Bob wished he'd ordered that extra truck load of counterweights"….
Especially so when 2 cranes are trying to tandem load or unload a boat, the strap slips, the boat falls, the crane falls into the water, then the other crane falls into the water….and they all quickly sink…
Hopefully the crane operators were able to escape safely.
Check your crane load chart that’s on the machine for the load configuration you happen to be in (main, luffin, jib and their lengths, etc) plus counterweight and load weight. Then you must know your lift radius. The main thing is you have to do it BEFORE the pick. Wind loading and ground compression factor in as well.
Cranes are noisy, sure, but not dangerous! Please forgive my fowel… language. Lol
Thanks
Kranplätze müssen verdichtet werden!
Hey, why can't I save this to my "Engineering" playlist? That button isn't available. That's weird.
The AWoooooo❤❤❤❤
In Germany, we have a meme going on for crane operators:
"Kranplätze müssen verdichtet sein!" which translates to "Crane locations have to be compacted!"
Great video.. just a comment for your algorithm
How about computer assistant that monitors' EVERYTHING with load sensors
Very interesting.
There was a crane collapse some time ago near the place i live. (Literally 2 streets away). A crane broke into a manhole cover that was covered with gravel. It slammed into the roof next to it, lost its structural integrity and bent over. They needed 30 minutes or so to cut the poor operator out. Luckily he survived with i think no staying injuries.
7:30 As a wise man once said: "Kranplätze müssen verdichtet sein!"
Kranplätze müssen verdichtet sein!!
you're so handsome
I hear the accident at Battersea may have been caused by a giant flying pig that was seen floating over the Battersea power station…
Practical Engineering i need to be able to communicate with you to plead for your advice. I am quite happily driven as an independent photographer of all things construction based in Vancouver BC. Canada. Should you ever desire an up to date photograph of architecture and engineering projects here in Vancouver I volunteer to take all you desire then some as I have been routinely photographing what I have for the first 3/4 of my life actually building. Hoverer due to an accident I have been healing from a physical state of quadriplegic limitations. I now can use both my hands and legs mostly though I have some more training left before I can put my electric wheelchair way for good. I have worked hard to collect ovr 20 years of daily photographing of Vancouver's building boom. Please leave me a reply under this my comment so I may know best how to glean ever more what drives you to share your wonderful talent and hard won training, I'm sure. Please give me a chance to inquire how you got this far so far a very good YouTube YVO Thank you…. Why Cranes Collapse https://youtu.be/LxdjSG5IFds Practical Engineering
I love Engineering… Makes me feel even more grateful to have known life as I live within it's fantastic precepts & principals. I really like your teaching and sharing what knowledge you have faith in. I love Engineering… Thank You very much for another well made Video YouTube Why Cranes Collapse https://youtu.be/LxdjSG5IFds Practical Engineering YVO God goes with you teacher.
What an uplifting video
Its called bad operators not doing there job they were trained to do.
Kranzplätze müssen verdichtet sein!
You burnt the tortilla.
7:24 Kranplätze müssen verdichtet werden!
@0:37 "moron that" is why most cranes fall
Here we are again.
Good information here.
I had driven through the intersection in a tractor trailer delivering to a local grocery store the day before the crane in seattle mentioned at 2:38 collapsed
Saw the news the next day and was absolutely flabbergasted
Nicely said sir.. This information is on point..
Genius..i am a lifting supervisor….i need this video😍
Never ceases to both amaze and terrify me that people trusted with such high stakes responsibilities can be just as lackadaisical as the average person.
Love seeing the fam 😂
I got to climb up a tower crane and took a ride around (360!) on the jib. It was awesome. The operator told me he was scared of heights. I lol'd pretty hard.
Listening to this at work, just now preparing to move a 104-pound cylinder head with a 50-ton gantry crane. Should be in tolerances.
3:51 isn’t that the factory from Pink Floyd’s Animals album?!? I never realized how massive it was.
As someone who likes winging things I get annoyed at his statement about making lift plans. Things I do usually work better than other people's "planned "work. Just so glad I don't do this kinda jobs where I could get sued or ruin life's for mistakes
Und ich sach noch… Kranplätze müssen verdichtet werden!!
KRANPLÄTZE MÜSSEN VERDICHTET WERDEN
Engineered right to the edge of the 10x safety factor I hope? Lol
Do those extremely tall cranes have anemometers to keep the operator informed of the wind speeds so he or the machine can adjust or stop work accordingly?
3:51 instantly recognized this power station as the album cover for animals
Any German who used the internet will tell you: "Crane sites HAVE to be compacted"
A few years ago in Holland in the village where I lived at the time, 2 cranes collapsed standing on pontoons carrying a bridgedeck. https://youtu.be/i10kOduKpaA
The case was quite complicated, as far as I understood it was a combination of underpaid subcontracting, at least 1 pontoon that wasn't suited or not loaded well, and wind. Houses were destroyed but miraculously, the only fatality was a dog.
Excellent video. (Working as a structural engineer at a leading crane manufacturer. All failures in the video are well-known to me.)
3:51 thats the pink floyd animals album cover!! small world
