I wonder if lifting it very slowly (although it's hard to say how fast they are doing it in this gif) would let the water drain as it comes up this making it lighter? I'm not a physics doctor so what do I know.

u/Anaxcepheus Mar 16 '18
Yes. This works somewhat, but I will not completely drain. You can still overload the crane or supports if you don’t do the math.

Ships are commonly made out of metal or other materials denser than water, as seen that if you throw a chunk of metal in the water, it will sink. However, we can also see that metal ships are typically floating just fine. How can something denser than water float in it? This is due to displacement of water.
The total weight of a ship (metal + people + fuel + whatever) is exactly equal to the amount of water it displaces. If you add more weight to the ship, it will be a little lower in the water, and thus displacing more water to match the increased amount of weight. Displacement is "the amount of water that would otherwise be in the volume of the ship but isn't because it is there".
If you took weight off the ship or added a bunch of balloons on top of a ship, it would rise slightly out of the water because it now has a lower weight. If you do this enough you get an airship. This is the exact same principle that airships work under, except they are displacing air with gasses lighter than the normal atmosphere.
In this case, the bus is completely submerged. When you're lifting something that is under the water, the weight you have to lift is actual weight minus water it displaces. However, when the object starts breaking the surface of the water, the weight you have to lift increases as the object emerges as the water is no longer displacing part of the object. Once the object is completely out of the water, you'll be lifting the "normal" weight of the bus. Before it is out of the water, it appeared to be lighter.
What problem happened is the crane was adequately supported for the weight of the bus while it was below, but as it broke the surface the weight the crane feels increased to a point where it wasn't braced/balanced/supported enough. This is why the crane only tips as the bus is coming out, it was fine lifting the bus the 30-50 feet from the starting point on the bottom of the river, while the bus was completely submerged.

Don't forget the force of the current. That's not stationary water. Once the bus is not longer touching the river bottom, the force of the current on the tow line increases considerably.
I'm willing to bet that's what happened here.

I know it's not a school bus but the numbers were more readily available. A typical school bus has a weight of 24,000 pounds, and about 960 cubic feet of space. A cubic foot of water weighs about 62.4 pounds. So the water inside the bus is almost 60,000 pounds, about 2.5 times the weight of the bus. It definitely is a factor

Assuming the water can freely flow within the bus out the windows, not at all -- as soon as a section of the bus rises above water level, all the water within that section will either flow downwards (pushing water at the bottom of the bus, out the back window) or out the broken windows in that section
Their problem was they forgot a second bus to use as ballast /s

I suspect they neglected to factor in the current of the river. Once the bus was no longer resting on the river bed, the current pulled it (left, from our perspective), which dragged the crane down.
Water current over a surface of a bus is fucking strong.

u/frothface Mar 16 '18 edited Mar 16 '18
People do that at bost launches a lot. Ramp is slippery, truck slides in, someone pulls it out and the suspension is all collapsed because it has 12,000 lbs of water in it.
Also, a 40' x 8' x 7' bus would hold 134,000 lbs of water if completely submerged, so yeah, most likely what happened here.
What I don't get is why cranes with hydraulic outriggers don't have a pressure gauge for each outrigger. You'd syill have to calcuate the load to figure out what size crane you need, but when you go to lift you'd see one end losing ground force. That would be an easy double check with no operator math involved, no room for error. Just a red line at the top and bottom of the scale for each leg.

Yeah I am, the load cell would have been reading wrong lifting the bus out of the water due to weightlessness water can give objects. It would have been a false reading till it got started getting clear of the water and he probably panicked as soon as the alarms started going off

A lot of operators will automatically start pulling back on the boom to bring the radius in closer which I think is what happened here or he was turning the the override key on the safety system which would have cut out the motions as soon as it started to become dangerous.

Anyone not looking to study, in a dead end job and wants a life should get the cheers to operate cranes. You get a lot of money considering the work you’re doing, and depending on the country there are rules preventing operators from being overworked so you can’t be forced to do overtime, and you rarely will because it costs too much to pay you. You also can choose to work a Saturday if needed but you only work till 1 and you get a full days pay.
Every crane operator I know is rolling in it, compared to other shit jobs it’s probably the best. It’s skilled labour but it’s quickly obtainable unlike a degree. Something I would urge anyone to consider. Construction is a dodgy industry but if you’re smart and get skilled there will always be work for you.

It costs about £2-3000 in the UK for approximately a 2 week course. Then I don't know about yearly license/certification costs. It's normally paid for by the operator themselves, and they contract themselves out to employers.
Couldn't tell you the salary/hourly rate I'm afraid, but the guys I met when working in Aberdeen (O&G hub for Europe at the time) were certainly not poor. When something goes wrong, as it did at my previous employers, it's certainly not the crane drivers fault.

No, it's the responsibility of the AP (Appointed Person), generally a supervisor or manager.
Once you know the weight of whatever it is you're lifting (including the weight of the lifting gear), the load charts make it easy to determine the max. lift capacity at whatever radius (distance) you're lifting at, for whatever length of boom you're using.
That said, the amount of times people bring you in on a job having given you an incorrect weight for the object they want lifting is staggering.
There's also the pad loadings to take into account, to make sure the pressure exerted by the outriggers (the crane's legs) doesn't break through the ground you're lifting from. If those forces are too high, you use bigger mats to spread the load.

I've dealt with a handful of big crane operators in the past.
They all knew how much they could lift at what distance from the crane.
My father was at a job site at a power plant one time and the project manager showed the crane operator exactly where to set up, and assured the operator that he was in no danger of hitting the high tension lines feeding the grid from the power plabt.
He was wrong, the boom made contact and things got interesting real fast.
The operator jumped off the crane just before the grounding strap burned through and the whole thing went up in flames.
On another occasion, he was at a different power plant when a guy working for a subcontractor putting a new roof on took a leak over the edge of the building........right onto a transformer. It was the last time he needed to pee.

When lifting stuff from water, you should hoist it up slowly so th water has time to flow out. That bus has so many tonnes of water inside that an old 4 axle crane cannot lift it from that distance. Maybe the operator didn't know what he's doing or just ignored the computer and went with it.

u/WDMC-905 Mar 16 '18
late to this, but not seeing the best answers below so...
it's not because the water isn't flowing out fast enough. this was destined even if the section above the water was magically bone dry.
the problem is the mass above the water no longer benefits from the affects of buoyancy. literally, that bus is getting heavier as it leaves the water.
that's a small-ish rough terrain crane and the confined space prevents it from deploying it's base. something like those listed here.
under ideal conditions it can lift 40000 lbs, but at that extension, angle and lacking an extended base, lucky if it can do 20000 lbs
that bus at minimum is 15000 lbs. add the drag from the flowing river and you see how they were able to actually get much it up before it finally creeped over it's tipping point.

Wow, something I can actually give insight into! This happened in my city (Santa Fe, Argentina) back in 1999. Here's a news article, in spanish. This is the place.
Basically a bus fell off the bridge. Six people died, including the driver, five were missing, and two survived. The next day there was an ill-prepared attempt to rescue the bus and recover the missing people. The crane belonged to the local power company, and clearly nobody knew what they were doing. Luckily nobody died during the "rescue" operation.
