- An unfortunate incident the cause of which at present remains a mystery. Several people have said they knew the crane driver who been doing his job with no problems for a long time.The tipping is seen to occur as soon as the crane is rotated.The boat owner is wearing the red shirt. Significant damage has since been reported to the boats propellers and drive shaft. This is a condensed version of the wider coverage of this event as seen in Part 2 of the video WATCHET SUMMERTIME EVENTS WEDNESDAY 23 AUGUST 2017. The boat arriving at the Marina can be seen in Part 1 of that video series.
The description says it all, really - They'd been doing this for years without incident & became complacent.
Allowing people to stand in harm's way & operating the crane beyond its capacity:
As to then working under the load After the crane had already toppled once?...
I’m a certified crane operator so I’ll add my two cents. this is a classic case of overload. I’m sure no one checked the load chart and I’m sure no one knew the weight of the pick. Lots of guessing and this is the results
Thanks for the input. I knew the outcome of the video ahead of time, but that crane looked too small for a boat built that heavily even to an amateur eye.
@@scdevon actually the crane might have been adequate for the lift but the capacity changes with the angle of the boom to the crane centerline. So if he picks too far out he has reduced the capacity of the crane to make the lift. So if that’s a 100 ton crane but his pick is 50’ from the centerline his actual capacity might only be 35 tons and he’s also over the side of the tracks which might also have a limiting factor.
They put load charts in cranes for a reason. I'll wager that the operator didn't know the weight of the pick, which does not matter, because he more than likely didn't read the load chart any way. Who was in charge here? Anybody???
@@pogojava,
Not knowing the boat weight and centerline details, it was the placement of the side of his tracks you mentioned that first caught my attention.
@@SteveTheFazeman actually depending on the crane model some have capacity 360 around the crane. But that being said usually the best stability is parallel with the tracks over the front idlers
I can't believe all those idiots standing under the line of the cranes boom, or the fact that the operators didn't move people out of harms way first.
juzzlookin If you didn’t have those idiots you wouldn’t have this video
I think you just nailed the cause of this mishap! As soon as I saw the crane, boat, truck and the reach (without outriggers) of the crane, physics lesson was about to follow!
Proud owners are watching with their cells. What they weren't told is that the three stooges had been re-incarnated and hired for the task of plopping Sloopy Sally into the briny ocean tossed
The level of incompetence shown here is absolutely stunning.
you got that right. I doubt that they had the load weight or the maximum load radius before starting. The crane was lifting over the side...weaker quadrant. And the by standers don't even mention the bystanders. They could have been all wiped out.
@@mactcampbell Yeah, the spectators seemed to be standing in line with the jib of the crane whilst it was teetering, if it had gone I think a few would possibly have been crushed.
Gregory P How many boats did you lift into the water then?
@@otto16121970 It doesn't matter. The basics of crane operation remains the same. Part of doing a lift is planning the lift which includes determining load weight, crane's capacity at load radius over the side.
mactcampbell you’re better off starting over the side than ending upon the side when you put it in the water
Yeah when a crane and it's load is about to fall the wise thing to do is stay near and act oblivious to the situation.
What crane?...what are you on about?...ere why is that boat shaking around in the air like that?...
guys watching dont realize the danger they are in.
The crane tracks should have been aligned mid position between the lift and the drop position for max capacity and safety margin, they are much longer than their width
was going to say the same thing.
all this needed was the Benny Hill theme playing along with it.. unbelieveable
Perfect. I so laughed.
Leave me alone and don't tell me how to do my job! I've been doing this for years. Oh...Sorry for the damage to your boat. It's his fault!
I was able to video another boat lift at Watchet Marina yesterday with a much larger crane and better security! I will be uploading that today!
That little boat is too beautiful, a one and only!
"Let's stand....UNDER THE BOOM!!!!"
Yes , everyone gather around .
Darwin says, “Its ok.”
Did somebody say BOOM?
Conversation one night in a pub --
'I gotta get me boat lifted off a truck into the water'
"Well me son, I gots a crane"
'If you can do it, I'll hire ya'
"How much does she weigh ?"
'Oh about 20 tons, what's yer crane able ta lift ? '
"oh I'd say ...about 20 tons"
' ahh well then, we should be good to go'
-- and that was all the professionalism needed
Put that crowd on back crane for counter weight
Great answer!
Boom up as much as possible,
Walk load toward channel.
Forget all the health and safety, they would have know the Swing load Weight of the crane and the weight of the boat. The crane is obviously man enough to do the lift, however, nowhere near enough counter balance on the crane, for lifting that far out, the crane needed to be closer for a heavier lift . If I was the owner of the boat I would be apocalyptically angry
You obviously know zero about cranes
Single Fin, the further away you lift, your centre of gravity changes, therefore you need a greater counter weight, by lifting closer, you decrease the distance from your centre of gravity, hence why the crane righted itself and lifted the boat with ease once the boat/lift was closer
Ross White crane charts are made up of 2 things stability which you are talking about and structure which just randomly adding counterweights means you might as well throw the charts away. And yes in video he has dropped weight luffed back and taken weight bringing the load back in radius of crane
And just so you know any crane is man enough to do a lift you just add more parts of line to the hook end of the day if the cranes to small it’s to small but can you please tell me what swing load weight of a crane is ?
Single Fin when a tracked crane or machine/excavator has its boom across the tracks and not parallel to the tracks, this is swing load weight, lifting side on with a tracked machine/crane actually decreases the surface contact stability, this is why a crane/machine will always lift a heavier load with the boom running with the tracks ( parallel ) to the tracks not across as he is in this video.
I've seen a thousand of these cranes tip over on u-tube, the operators really need more training!!! I can lift 20,000 lbs and the boat weighs 25,000 lbs, NO PROBLEM.....
no mystery here! exceeded the cranes capacity its starting to go before he started to slew around..... no mystery just basic physics
If ya NEVER Stand under it !! then itll NEVER drop on ya !!!
Can't blame the old RB for trying. The crane was simply overloaded at that radius and the driver not smart enough to know his track is lifting. HSE will have a field day on the lack of planning and training.
I do wonder what past experience he had had!
The tracks of the crane should be facing the lift area ie facing the lorry and slightly to the right between the lorry and the dock edge. The crane is at its maximum lift capacity. See this to many times the marinas have small cranes that was bought second hand or years ago. I’ve only seen one marina that a capable crane for doing the job. It’s all about preparation. Should be been done at high tide as when the crane lowers the boat into the water at so a low gravity takes over and if it falls to fast the cranes brakes could not take the strain.
in the Uk a lift like this must have a risk assessment in place before lifting, which must include all details of the lift i.e. weight of load/crane capacity/ date of lift / safety precautions used and more importantly the oppointed person and lift supervisor in charge. clearly none of this has taken place here and they were lucky no one was seriously injured or worse.
Well said, Mark. Most people watching this will think, 'Oh, wow, good that it turned out okay.' The crane company should be jailed. Cranes aren't Tonka toys, folks... Sheesh!
And did the H&SE prosecute the idiots who 'planned' this lift? I doubt it.
Looks like they don’t have weight gauges in England and/or load charts. Sounded like it was an old friction clutch crane too , the kind Noah used on the Ark Project. Next time get an Aussie Crane Crew and get the job done right. For starters we don’t let bystanders inside the work zone. Next thing is knock a section of boom out of the pin jib , looked like he had the head height for it. Better still get a crane with the appropriate lifting capacity for the task.
I and many others are looking forward to seeing the job done properly next time!
th-cam.com/video/4OOg7vL3rNY/w-d-xo.html
First thing I thought of was telling everyone to get back! That didn't happen.
Looks like an inexperienced rigging crew and operator, and it is lucky that apparently they do not have the US equivalent of OSHA or fines would be in order.
Too many spectators and lookie loos under the boat. The man in charge should be hanged from the yardarm.
The lifting charts on those old cranes were on the seat when it started to lift you were a bit overloaded.
Yeah, the pucker meter.
the controller of lift failed completely..there is ultimately a single point of responsibilty for failure or success period of a pick', that person has the data, criteria, capacities of equipment... and has the go or no go liability of command...oh and that person failed on this pick' in video...
Boom UP !!!!
That water looks horrible, can’t imagine putting such a beautiful boat in that swamp pit.
Its low tide by the looks of it, looks like sloppy mud
southerneruk ......another reason not to be lifting the boat into the water
Vynle Shmynle You are aware that in many harbours boats sit on the mud twice a day, every day, when the tide goes out? There is nothing wrong with lowering a boat onto the mud at low tide when that is where it is destined to end up most of the time!
Spencer Wilton I wasn’t aware actually, I live on the Great Lakes, thanks for the lesson
Jaws (we’re going to need a bigger crane)
There's no mystery here, the center of effort moved forward and the crane doesnt have enough counterbalance or foot print to handle the weight. They were lucky and not destroyed that beautiful boat. TH-cam is full of cases like this of cranes dropping boats on land or in the water, sometimes upside down. The best way to handle a boat in any decent yard is with a proper Travel Lift
I agree with you but the tidal range is massive there and a travel lift wont reach most of the time.
I have never seen such a badly organised lift in my life. Did they even have a lift plan. If they did, it's clear that it wasn't worth the paper it was written on or it was completely ignored.
If the HSE ever get to see this they will have a fit, shocking, simple as that.
That NCK had no chance at that radius. Hope the operator lost his license over this. Pure incompetence. Lucky no one was hurt. Should have used an RT with outriggers.
The crane operator needs to be fired ! Never lift a load like that over the side ! Hope that boatyard has insurance.
I never have operated a crane, so bear with me for my unitiated questioning if they don't teach those crane and heavy lift crews the fundamentals of Technical Mechanics and its extremly useful method of sections.
It isn't really Rocket Science setting up the basic equations of momentum and force balances.
Of course for that you need to know the mass on the hook and roughly its centre of gravity.
But every ship owner should roughly know its light ship mass; maybe the shipyard could provide the data, or one could deduce it if one knew full load displacement and max. deadweight and bunker capacities.
If those Straps slip front to back or back to front it changes all the parameters and centre of gravity and can end up slipping the boat out the end !! . Spreaders Fore n Aft n port n starboard ALWAYS !!
Not always! Sometimes!!! But not always!
Decent rig up! Poor lift plan
And they are walking underneath an unsupported boat, held by a crane that just failed, unbelievable.
Anybody with brain would lift it just off the supports to see if the crane is man enough ! If its on the border line / tipping point the get a bigger crane ! Or if the crane has it but no more then continue the lift inside of the existing parameters
0:50 Boat was already in the air. Why did they pull it any higher? Just few centimeters would be enough to take the truck from beneath....
I second this comment
👍👍👍😜🦄🏴🎣😁🤞✌️
Spot the mistake? The crane driver had the tracks facing the wrong way?
Nope
Wrong way if his intent was to offload the boat onto the wharf. Right way if his intent was to swing and lower the boat into the water. Too much boat for the crane either way.
Wrong if you have no idea on this subject I wouldn't pass comment
Cranes are NOT "driven", they are operated, and in this case not operated well. This was a bad idea from the beginning and either the weight of the boat was not told correctly to the dock company and or the crane is under rated for the lift. The start of the swing was not smooth, it was a little jerky showing how ill thought out the lift was because the crane was trying to lift a load that was too heavy. The boat owner is lucky that the accident (drop) happened where it did because the crane would have had to "boom out" to get the boat into the water thus making the lift even more faulty. The further away from the crane the more the load weight affects the balance of the crane and it's lifting capacity. If the crane had swung the boat out over the water, it would have probably been dropped in the water with the crane falling down on the boat into the water and both would have been sunk.
Very good post, only thing is that its a crawler crane, so it can't "boom out" only telescopic can boom out or in, Crawler cranes only can top down or up, That is the gib being lowered or risen
@@southerneruk By "boom out" I mean boom down, or lower the boom to a less steep angle so the load is further away from the crane. I have run lots of cranes, hydraulic cranes, draglines, and back hoes (hydraulic excavators).
@@randallfrank5682 ok np just used the wrong terminology, I am a rigger top grade, done the 8 year training, 4 deep sea, 4 on terrestrial (old school)
Not a bad idea just not implemented correctly
I operated a 30ton capacity railway steam breakdown crane for years at 16foot radius with outriggers out and cliped to the rail the lifting capacity was 30 tons but at maximum radius of 40 foot the lifting capacity was 10 tons and that was on level track no superelevation which brought the capacity down ballast at the rear was the boiler and water tanks when working free on the rail on with superelevation track and the jib over the high rail if you jibbed in to a certain radius the counterweight of the boiler would cause the crane to topple backwards
I'll wager the Port shaft is bent and prop doesn't 'look' right.
Then again the boat should be launched at high tide !!!…
A "MASSIVE SHOUTOUT" for the CRANE DRIVER, such a "cockup". HAS HE GOT THE GUTS TO DEFEND HIMSELF AND PROVIDE AN EXPLANATION IN THESE COMMENTS??????
There is absolutely no "mystery" to this at all. The boat exceeds the rigged capacity of the crane. A side lift without outriggers is one of the least stable lifts, and this is the result of that instability, combined with the weight of the boat.
That boat will need a complete lower inspection........prop shafts,propellers,rudders.....in fact all underwater areas.
Shafts, props anything involved is gone. Why? The engineer responsible for the calculations of the weight. Who weighed the boat? To continue was the greatest stupidity.
The crane should have been between the truck and the wharf not behind the trailer
The tracks facing the water
Boom all the way up with the boat sideways (not longways) against the boom slowly spin around boom out only as much as necessary to lower the boat into the water or...........
Crane topples over
Boom falls directly onto the people watching
Boat is destroyed
People die
Insurance pays
Dumbass operator finds another job
All crane accidents are preventable...including this one. This one is especially stupid!
Crane driver myself, and answer given.. thought he appeared to hoist too fast too, adding to problem, plus crane ‘’ square on’’, if he had plant at a diagonal angle , to boat and took load in fast he might had pulled it off, but obviously counter weight on lifting plant too little for job in hand.. double weight if what u think it and set up crane that way,,correct slings too, and do job slowly and safely by experienced people.
That’s why I use a yard with a Travel lift the Yard Owner /Operator also runs a Marine Transport Company and has a Fleet of Hydraulic Transport Trailers he utilizes to move boats around the Yard to block them up on the Hard for bottom paint and other yearly Maintenance Another nice feature is it is owned by a Local Husband Wife team and they know who my Freinds are so they Block me up next to those people
What a beautiful Vessel i’m agreeing with the comment from the certified Operator unfortunately many boat owners only speculate the vessels weight ive owned 17 or 18 of them and sadly all most owners have to go on is the manufacturers specs and dont update the records for additional equipment and water and fuel i personally try to get my haulers scale weights whenever possible and /or use a crane with plenty of capacity or more at a cost of course
Plenty of boat...not enough crane. The semi would have had the weight from the scales, could have passed it on the the crane operator. "We're gonna need a bigger crane".
It looks like rain
I know let’s all stand under the boom so we don’t get wet!!!
Yeah !
That’s a great idea
Me too
Oops it looks like raining boats
I know let’s all stand here and watch with mouths agog
Good idea I think I’ll join you
You can get a better view if you stand here mate
Oh! Okay
Gordon Bennett
The incompetence just goes on and on
At one point I was praying he wasn’t gonna stick it in the water !
Not much to see here. This video is worth only to show that some boat lowering can be reasonable enough to be stopped before disaster strikes. But whole 10 min of it? Only if you live a boring, slow-paced life.
If the truck was side on to the crane this wouldn't have happened the crane is boomed out too far for the weight. Dispite everything I think they did an amazing job of saving this situation from becoming a far worse disaster.
Smart truck driver, "exit stage right."
Backwards even
We all thought that this was incompetance but compared to the Cardiff Marine group who have taken over Watchet who work on an altogether different league of incompetance it seems that the Marina is now for all intents and purposes not fit for purpose and with the near collapse of the Marine group it is expected to shut its doors in Watchet and the other marina's on the Welsh coast under the custody of scoundrel known as Christopher Odling Smee .
Fascinating reading the comments everybody is experts on crane lifting and have license and all I suppose :D
I must say, many folk could have been injured or killed here. No regard to any basic safety. When things started to fall apart, nothing changed in the mood, it was all in a days work, until the someone actually dies.
Had the Crane in the wrong place, should have been along side the boat with the Tracks 90 degrees to the Boat. This would present the widest base and the lift would be much closer to the center of the Crane.
Holy shit I would never walk around and especially not UNDER the boat in that situation
Another gullible crane operator who believed the ground crew's weight digits. poor him. More so that he probably did ot know how to find out for himself the real weight of this boat by checking the water displacement...and then the weight he could lift at a given angle of tilt of the main boom.
The crane operator was drunk or an idiot to have the tracks across that way!
Knew I wasn't the only one thinking the same. The position should have had a longer corner aimed at the boat. Doing what he did he took away his leverage.
He needed his tracks that way because the water is farther away, which needed the idler side
With the crane at risk of falling onto the boat, why are people putting themselves on the underside of the boat?
CRANE DRIVER OBVIOUSLY HAD HIS TRACKS SPRAGGED THE WRONG WAY !! HUMANS ARE BUILT TO FAIL UNFORTUNATELY ! COULD HAVE POTENTIALLY BEEN A LOT WORSE
What a dave but he definitely damaged the boat and the sucky part is most places like that will fight tooth and nail not to have it fixed at there expense. But the camara guy must be jim Cummings. Lol
I’m a cane operator and this crane is way to small and picking from the side.this is the least stable over the side if this guy had a certified with the cco this would never of happened it looks to be a 50-60 ton crane and that’s what it Weighs ,not what it can pic !!!
I fear Watchet Marina is overdue for a financial investment all round. There will be one in terms of the buildings I understand but the boating side does need updating!
you are no more a crane operator than the man in the moon is the listed tonnage of a crane is how much it will lift not what it weighs, you must have been the dumbass in the crane in this video
"... if this guy had a certified with the cco this would never of happened ..." seriously, you mean a two week course?
Brad Darb you also need years of experience I ran cranes way before cco ever came out .i hear a lot of negativity from people enjoy the tide pod
Brad Darb plus your supposed to have 1500 hrs before you take the test but some companies Lie as in your case obviously good luck on your short crane career
Appauling incompetance - and not a hard hat in sight.
What kind of crane driver is that? Swinging so violently. I would let the boat to be checked first and let those guys pay for damage before putting it in the water
Bunch of cowboys, none knew what they are doing, you got a group of people who know banking signals and that is it, they using a crawler crane that has no counter balance, they got the crane top down to much for the weight its going to pick up. this is where it pays to pay the extra money for guys that know what they are doing, so simple mistakes like this don't happen
it looks like nobody checked to see what the weight of the boat was if it had a label if not don't assume the crane will lift it lt best to get a bigger crane in to be sure plus the boat should have been pointing the same way as the tracks having the boat side ways to the crane your asking for trouble plus the crane has no stabilizers
DAM, people all cranes have a weight limit ! does no one pay any heed to limits ? The weight limit chances the more angle the boom is from upright.
Should have just put her straight back on the truck & back to the workshop. Bet the owner was pissed.
10k plus to replace that running gear. Don't ask me why I know.
out of curiosity: why new running gear? Because of the overload? Or because of the dynamic load peaks when the boat got free from the trailer and was swinging?
Running gear on the boat
Rudders, propellers, propeller shafts looks like all of it hit the trailer
No mystery, To much weight for that radius.
As a Union Ironworker and a crane builder these people shouldn't be on the hospital side of the crane.
Destroying 60 years in about a minute, almost.
Sallama vinçler genelde kum çakıl kiremit işlerinde kullanılır onlara daha çok yatkın makineler limanlarda kum çakıl mıcır depolarında arkadaşlar bunlarda ayak sistemi olmadığı için genelde böyle oluyo
I am glad to say things are done much better these days!
Low tide as a plus. For extra falling height. 😂
From a experienced crane operator this is a very simple accident, the crane operator messed up.
Or he was given bad information to start with but did everything correct. Either way poorly planned and poorly executed by the looks of it.
That's not water in the harbour it's mud the tide is out therefore there can't have been any intention other than to offload the truck. For those who don't know Watchet the tides are very extreme between high and low tide, at low tide the water is nearly half mile out from the harbour. West Somerset has the smallest District council in the country and is completely broke
Sadly true. One of our beach car parks is soon to be closed because the council cant afford to repair it. What a state to be in!
If you keep electing Tories you get Austerity. At least Labour is no longer controlled by neo-liberals.
nice bit of leg can take my photo anytime
If they were just unloading truck, the boat could have been lifted and the truck driven away, then the boat lowered onto stands. There would be no reason to slew the jib like that?
Boss ,boss , send over a truck load of counterweights and a small crane
Should of been put back on the truck and sent back to repair the damage. Simple case of a so called operator that can’t read
I hope they were only lifting it off the trailer and not attempting to put it in the water.
Its a good job it tipped were it did.
Believe me when I say the lot would of gone into the harbour if they tried to put it in the water.
I would say that the tracks on the crane are facing the wrong direction. They should be in line with the boat, not at a cross angle.
Boat lift??? No worries - Hold my beer !!! 🍺 😬💪🏼
Ain't got clue what their doing, at least the high viz vest will save all!! Lol..
Not ideal but better to lift over the side like that and find out the crane can’t hold the load over the concrete than when it’s over the water
It may not look like it to some but that’s a very heavy boat the way it’s built.
You would think there must be some legal requirement for the weight to be declared correctly to the crane operator, and he must have some certification to show the crane can deal safely with that weight.
Haha. The weight is the displacement of water. There is no such thing as heavy build as it looks. It just have a bigger displacement of water. I think they should not picked it up this way. Better have the boat square to the crane so it reduces flight.
when it's out the water it is heavy
I had a closer look at the boat in question today in the snow. The video should be on line tomorrow.
@ Admiral Scorner: It isn't possible to run a marina in that manner, the sheer bureaucracy would sink the business.
Whats so amazing about that crane ? that crane is terrible!!!
Hi Mike looking at it from my experience of operating cranes, it looks like maybe two things an inexperienced crane operator.
because he was reaching too far forward and put the crane off balance over and above the counter weights.
He is lucky he wasn't doing it over the water or everything would be down in the bay.
I bet he has not enjoyed many good nights since then!
Holy Shit they are Freak'n LUCKY !!!!! Just by the Mk.1 Eye ball you can see that the Crane is not Hefty or Big enough !!! JC !!!!
The next lifting session I saw they had brought in a much larger crane and kept people well clear!
PORT RUDDER AND PORT WHEEL WENT THROUGH THE BOTTOM. THATS ABOUT 50 TON TROLLER.
Why do you think they named it the "Watch It!" Marina?
Crane Operator: "note to self, old wooden boats are MUCH heavier than those new fangled fiberglass boats I'm used to."
word
Can't fix stupid so you gotta fix what stupid does
Should those people be standing in harms way?
The crane didn't have enough counter weight...
I know little of overhead lifting. But the people so close.. 4 minutes in they FINALLY get people out of danger area. I have used a track hoe to lift stuff. You don’t lift max 90 degrees from direction of travel. Huge danger is lowering it over wall. I would point tracks @15 degrees off strait at wall. So my lift @30 degrees off ideal. (But closer to me so it balances out). As I swing I get BETTER stability. As I am forced to raise load over railing (looks like anti climb fence above?) and boom out. I am at my most stable. Once clear of wall slowly lower, and not stop. It could have been much worse. I have done sketchy. But that was bad.
He will never do things that way again I am sure!
No entiendo que quisieron mostrar, una verdadera estupidez
Good thing it wasn't picking it up out of the water
lets play russian roulette with a crane and stand right in the strike zone
Is that Prince Charles commentating?
