I get that it looks risky, but I don't really see a problem here. The platform is in undisturbed water, no waves, no sudden changes. If the platform is strong enough, which it seems to be to me, it will not easily tip over.

I've worked on a few lifts like that, and if you manage to tip one over I can only say that you were either really stupid or you were trying to do it. All the weight is at the bottom. They are very stable.

The only way to make them fall over is if your floor is not level while driving. Driving is out of the question in this picture, and as long as both guys stay in the fork lift the center of gravity will not change much.

So the platform will not move, the lift will not move, basically they are fine.

If something was to happen you're fucked though.

And different solutions are available. I've personally been in a different lift that had an arm so the lift would be a the side of the pool and the part where I was standing was elevated above the water. That probably would be a better solution, if you have enough space to get one of those lifts in.

Disagree. The lift is on a gimbal. If the wheels on one side of the lift are 1cm higher than the other, that would move the platform at the top by 8cm or something. If both guys are on one side of the platform that could be enough to make the whole thing tilt by another 1cm at the wheels, and so on.

That lift is not designed to be operated on a plastic barge.

That dock is not designed to carry equipment, certainly not an elevated platform, and is not designed to be operated as a barge.

IDK why there's so many commenters here rushing to defend this kind of practice. Working at height, on equipment not intended for that application is a hard no. Why would you work for an employer that would put you in that situation? This kind of "it's probably fine" risk assessment is just absurd.

Well, have you ever stood on a lift like that? I did, on a regular basis. You can lean over quite a bit with them.

Also, the lift itself already has play. You can easily get it to swing 4 centimeters while the base is stationary. It's just play in bearings and metal slightly bending.

I agree that the lift is not made to be like that. But sometimes you gotta do what you gotta do. I've done worse, that is for sure. But you have to use your brain.

Clearly the platform has great floating capacity. If the platform would not be capable of carrying that load, it would have sunk by now. The lift is in the middle, who j means the load is putting equal pressure on all sides. That has a stabilizing effect.

Water also pushes back. If you've every tried to flip a raft in the pool, you know that it is much easier if you move it side to side a few times, the water wil help you push it over, as long as you keep adding energy at every swing. If you don't, you will stabilize.

Unless something keeps adding energy to the swing, the swing will only get smaller and smaller. If it's swinging too much? Just stand still, don't move and let it stabilize.

The one thing to keep in mind is that the higher you go, the bigger the leverage is. At some point it will probably tip over if you swing it too much, but I don't think those guys are at that point.

But in the end, this is probably not the proper way to do the work. It's fun to discuss it, but a professional company would arrange something else.

Still legendary though, I've worked for companies that would do sketchy shit sometimes and while dangerous, it was also kind of fun. And I always checked for myself first if it was safe. Because I want to go home at the end of the day. Doesn't mean you have to be scared of everything though.

Guy this just isn't true. The people on the top are on a gimbal (?) The further they are from the centre of the base the more weight is on their side and the further they will move from the centre of the base.

I'm not trying to be derisive or whatever but checking whether you think something is safe isn't really good enough. If that's the company culture then sooner or later some idiot injures themselves unnecessarily because they checked whatever thing and thought it was safe.

Safety regulations and certifications take the decision of whether something is safe out of your hands.

What makes you say the dock isn't designed to carry equipment?

How are they going to get out of the lift and how will they get the lift off fhe mattress?

[–] [email protected] 9 points 6 days ago (3 children)

If they have to get out of the lift, it is at it's lowest position. That means all the weight is in the middle of the platform and the weight of 2 man will not be enough to make the platform flip over.

They will have to jump to the side I suppose. Just step off. Maybe the can even paddle the platform around, I imagine there is at least one piece of rope to manipulate the platform when there is nobody on it.

The lift will go off, the same way it came on. Probably some sort of crane. I cannot imagine they just drove it on there, but maybe they did. Maybe even a forklift with long forks. There are forklifts that could probably handle that kind of weight so far away on the forks.

This is the type of thing that I look at say this can't possibly work, and the engineer beside me will look at me a little confused and say this can't possibly fail. Sure enough they're usually right. Usually. I still won't be climbing on there.

[–] [email protected] 6 points 6 days ago

Well, it's always best to listen to the little voice inside, especially if it says "I might just die here". I completely understand why you would not be climbing on that.

Make sure you have all your PPE.

If they had a short pole underwater in the middle of the belly of floating platform then it would be more stable than my 95 yo granny at 3 am on her way to the toilet

No idea how it works exactly but the sailing boats have it so to not capsize easily or at all. It actually takes great deal effort to crash the sailing boat on its side, these fuckers can go 90 degrees under heavy wind and still come back like a spring though no promise the people will be still onboard.

It’s kind of fun actually to sail almost 90 degrees on the side but scary.

those sailing boat keels are lead-filled (at least at the bottom) and hydrodynamic so that the force of the running water pushes it back to center. it's a lot easier to capsize a boat like that when it's not moving.

[–] [email protected] 8 points 6 days ago* (last edited 6 days ago)

There are centreboards (not lead-filled) that use the movement of the boat to counteract leeward drift and there are are lead-filled keels that in addition to that also act as a counterweight to reduce rolling. If it's lead-filled it'll be hard to capsize, if it's just a centreboard you can easily capsize it if it's not moving (and use the centreboard as a lever to recover it afterwards).
