- Three massive cranes collapsed during Hurricane Irma last year and all three were from the same manufacturer, Terex-Peiner, which still has cranes in South Florida.
I work on the motors used on these cranes. The four swing motors mounted to the turntable should have had the brakes unlocked to allow the crane to swing freely with the wind.
Yes this is a human's fault.
Lo stavo per scrivere ma c'è già il suo commento.
I'm mobile crane operator I have experience 17 years I need job
I work at morrow. I will agree
They were not? That is crazy. They should not hang out Terex like this when it is purely operator error.
Looked like the slew brakes were still engaged not allowing them to swing in the wind..
I just came here to read all the comments from people pretending to know tower cranes so we'll
Well*
Lol right, if I'm not mistaken those are supposed to "Weather Vane" in high wind to lessen wind sheer.
@@nicke1903 that's correct. It lets the wind turn the crane to the least stressful direction, into the wind.
Just thinking the same thing
Bruh im pretty sure that thr manufacturer didnt intend them to be up in a hurricane 💀
Usually a tower crane is tuning itself into the direction of the wind if it's not operating, to offer as little surface as possible to the wind.
It seems the jib got wind from the side and collapsed to the side, so something was wrong.
@@simonm1447 ever be in a huricane? Wind comes from all directions VERY fast.....
@@hdj81Vlimited if Wind comes from opposite directions it would eliminate each other - just look how the cranes collapsed, it don't even turn a little bit.
What is surprising however how the counterweight is mounted, it's rear arm is relatively long and the weight is relatively far from the turntable, what may be a factor. The jib always has to have more resistance for the wind then the rear arm holding the counterweight, to enable it to turn it into the wind. If the rear arm has too large surface it acts like a sail preventing the jib from turning, which leads to a massive sideway force onto the jib and it can collapse in the way it did.
This is the reason why it's not recommended to mount advertising signs ohne rear arm of such a crane without checking the allowed size together with the crane manufacturer
@@hdj81Vlimited have you? It blows from one direction as the front edge goes by and then reverses as the backside comes through . Slewing brakes were locked which is wrong.
The sk 315 can stand winds up to 100 mph they are designed for hurricane winds if weathervaned , the operator made a mistake in 3 separate cranes in the same hurricane
Maybe do some real investigating into the physics of tower cranes.
na they would rather just say shite they are 100% cluess on and ruin people lives for ADVERTISEMENT MONEY> money first TRUTH later
Dont lock the turn style in bad weather let them swing with the wind
Turn style? Do you mean a change in fashion?
@@killermurderer2208 turntable.
Most Terex cranes are excellent equipment. Though the 315s are the smaller version of 415 and 575s. They just need to get rid of those 315s in hurricane zones.
The 415 is already too small in my opinion. I haven’t seen nor operated a sk315. I love my 575 😎
I’m a rigger for an sk315 and the lmi literally prevents the crane from operating over 35mph
Terex is a pretty large construction equiptment manufactor , They must have some kind of wind restriction or procedure in case of high winds , that may not have been followed
yea the crane wasnt weatervaned allowing it to swing with the winds
Я сам крановщик просто надо было растормаживать тормоза поворотного круга чтоб кран крутился по ветру
It's not a hammer head it's a saddle jib flat top it's not a turn table its a slew ring . jib snaps off and crane collapsed because it's not put in out of service meaning crane wasn't put in to free slew meaning brake on slew motor had not been released so crane can move freely in wind design fault is the small tower section between slew ring and jib with the pressure on bottom of small tower + weight of jib + weight load + pressures of movement of load made by slew motor on crane put steel under high twisting pressure that put stress fracture in steel than driver didn't put crane in to free slew when finishing he's day of work = crane collapsed
Interesting information, thank you.
I was gona say the same thing. Usually to put the slewing motion into a more neutral state allowing the crane to jaw with the wind in these conditions. I know some newer models measure wind speeds and can auto turn or release and lock parallel to the motion of wind.
A 315 IS a hammer-head style twr crane. Linden-comansa made types are flat-tops.
Yes, it should have been put in weather-vane mode.
The person controlling them are called an “operator”.
There are other things that should be done to prepare a twr crane to weather a major storm that were likely overlooked as well.
All said is true, but why all the same model of crane? That seems to be the common denominator.
Good give them lessons man theese guys they are eating s,,, for money theese cranes are super but operators don t put them on the free slew that s the ideea I think or the automatic system failed to activate the free slew or was not working ,, properly
Man, I’m blown away at how high up there are. I just couldn’t do it.
I wouldn’t blame the manufacturer. A lot of things break in a freakin HURRICANE!
I have drive sk-415 for 10 years, no problem
I drive a CCT good machine
i drive my gf-143, she was flexible and never breaks. No problem.
SK 575 out in Utah high winds no problems
They don't look like they are weathervaning, it might be the operators fault?
1:03 There is a same crane that did not collapsed!
Looks like the contractor in charge of those cranes is at fault.
Sorry for asking cause my english isn't good enough to understand details what they were talking...
At 0.27., 1.57 and 2.13min.are topless cranes shown which were different to the collapsing one in the video. So is now the topless version the problem or the version which colapsed? Is there a difference between " hammerhead" and " top less" designs?thanks
100% operator error, that should have been in weathervane mode to allow them to swing with the wind direction, cranes of every type are extremely weak when side loaded.
Я согласен с вами
So your trying to say, Terex peiner sk315 are dangerous more than sk415, sk
515?
The crane is supposed to leave the swing break off so the crane can act as a weather vain. That makes a lot of difference in the wind .
God bless the all people and crane operator
They’re expecting a tower crane, a very sensitive type of crane compared to others, to survive a hurricane?
They actually can, well most models. Liebherr makes tower crane that are rated to 140 mph.
Вовремя шторма или при сильном ветре, надо кран растормажимать или просто снят с тормаза поворотного круга,и повернуть стрелу по ветру
Next time buy Libeherr guys...
Самое главное что крановщик не был в кабине
Why do they show Liebherr tower cranes?
Liebherr are thee DADDIES, the Rolls Royce of the tower crane world 😊
To promote German quality 🥰
Liebherrs are Good but favcos are the best..Australian design!
@@julianreverse which is going down slowly...
@@AB-vi3rt Favcos are just chap Liebherr and wolff lead the way
crazy it happened on 3 different rigs tho, maxim is a good company and i know ( for north east at least ) there are no company S.O.P's that says the turntable locks should be engaged when not in use obviously acceptations where the crane may interfere with other structures or equipment in its swing radius but that doesn't seem like the case here.
So now this reporter is a crane expert? I don't think so.
To be fair,those things have not been designed for the stresses they were subjected to. They would have been coping,with stress from every angle,every bolt.
Why would it take a week to count the cranes? That should be done in a day. Look at the development permits perhaps.
Who saw mcdonald in crane
probably due to jet fuel
lol I know what you are hinting at !
Free slew. Take the slow brake off
Slew brakes are not activated or set too hard.
Operator error all the way🙈🙈🙈🙈🏗🏗🏗
One of my ex wives works on the cranes. As a counter weight.
I saw this live
Well its a terex.....
I also ran a SK models nothing wrong with them it’s just those stupid news people don’t understand cranes
Bingo.
Stupid News people don't understand anything. They are all pretty clueless about anything remotely technical.
I only build the yellow ones hahaha
Most likely fault of improper setup/use than the manufacturer. Its Florida, its loosey goosey out there.
Operator was loosely goosey. Brakes needed to be released.
Simple they couldn’t spin
Terex is really the badest crane i operated. I hate them..
Gotta give them credit for at least consistency
This is a feature of deregulation, not a bug.
Nope. Brakes needed to be released. Operators job
Peiner is old equipment
Operator forget to hit the free slew 🤣🤣🤣 Amateur's
I AM tower crain machanic
and you cannot spell crane
Insurance scam !!! Shhhhh !!!
oh wow... joe biden said this wouldn't happen
its trumps fault
Liebherr all the way , dealt with crawler cranes all my career and Terex is by far the worst , even the china knockoff old style komatsu was better than a recently built Terex
And one of the main reasons this happens because they do not perform a magnetical particle inspection on all the welds
They probably had the brakes locked not allowing the cabs to “weathervane” in high winds.
You’re a news guy I am a crane operator you don’t know anything about cranes do your homework
I'm curious, why don't they ever take cranes down when they're finished with them?? Especially when a storm is said to becoming? Do people not care or, cranes are supposed to stay up in the sky? My apologies, for all these questions I always thought they were cool growing up! but, lol wow I never knew they were extremely hazardous in some conditions.
dont be affraid they put them down the moment they dont need it. if the crane sitting around doing nothing it costs money.
@@tomast9034 Ohh, okay, thank you!
They were still being used and taking one down for a storm is unnecessary and expensive.
Some people ignore instructions. One, can't ever be below 70°. Well, when they did that. It fell over.
They collapsed because... wait for it... there was a hurricane... imagine that? 🤔
What do you espect? ITS A HURICANE!!!!
