That is designed for that.
Right, each time I see this picture pop up, it's like the words barge and dredging don't exist. Like this thing is seen as some damn cast away raft or some shit. This is fine. It's just different.
If you showed a picture of a standard tower crane to someone with a decent understanding of physics but had never seen one before, they would similarly recoil and go "WTF why are you suspending a bunch of concrete blocks high in the sky on what looks like a pencil thin beam!" and it would take some explaining, OR it would take seeing it regularly for that person to become okay with it.
People don't see this every day, so they don't take it for granted, and therefore it looks insane. Just like tower cranes look insane.
Looks like it's going to pick up Seattle's Space Needle. Quite insane. /c/confusingperspective
This sketchy looking thing is safe, therefore all sketchy looking things are safe.

I'm familiar with both of those words. Ok also familiar with the idea of a lever-arm, and this one is too long for my sense of safety.
Most of the weight is at the bottom and you have to have the center of mass go outside of the base to tip over.
The ez dock base is more flexible than say, concrete.
The centre of mass of the lift only needs to go outside the base of the lift, not the dock.
WDYM?
what does dredging have to do with this?
Barges also typically don't carry tall tipping over things with people on top, and are less flexible than this plastic thing.
In the sense that something designed to carry 8,000lbs can probably actually handle 10,000lbs? Or in the sense that if they both died insurance would still pay out?
The floats are EZDocks, each with a carrying capacity of 3,000lbs, total capacity is 12,000lbs.
The lift is a JLG 3246es, which has a weight of less than 5,000lbs.
What if the lift tips over?
In order for something to tip over, the center of mass has to move outside the area of the base and most of the weight is in the bottom part of the lift. So it is basically impossible without actively trying to tip it over.
It's only "basically impossible" if it's on a firm platform. If it's on a gimbal, like a plastic floating thing, then you don't really now where the tipping point is going to be because it depends on the flexibility of the platform.
Probably why the bottom is also anchored to the floating work surface. This implementation looks like exactly what you're supposed to do. There's lots of pearl clutching for some reason.
Safe work sites aren't "pearl clutching".
Who says this is exactly what you're supposed to do?
If you're ever working at height and you think it's safer without a harness so you're not killed to death by whatever you're standing on it's probably a good time to reassess.
those blocks are not that flexible*
never seen them at festivals or some such?
they're much stiffer than they appear at first glance!
^*if^ ^they're^ ^properly^ ^linked^
Any flexibility will change the physics.
Guaranteed the specs on that lift say it can only be operated on the ground.
Guaranteed the specs on that dock say it's not suitable for supporting anything at any height.
They might get wet?
Uh, sure. You might also fall on the concrete walk way around the pool, or on the lift, or the lift might fall on you, or any number of things.
Yes.
Life insurance wouldn't be the problem. The problem would be if they lived and were injured. That would be a work comp nightmare. Just imagining getting that call is giving me a headache.
Okay, you go on and test it for us then

I have done way sketchier shit than that. That is like a 4/10.
This you?
That's like a 2/10. He has 3 points of contact.
I mean, you can see in the picture it's being done successfully...
