Thank you, I have no problem with elementary physics. (I am a civil engineer, specializing in physics.) But I still don't understand the basic idea. You say that the floating part should rest in the hinges during the lift. Am I then supposed to "fold" the bridge so that the top of the floating part ends up downwards on the fixed part? And the floating elements upwards? That is the only way for me that it can remain in its hinges. But I probably misunderstand you completely at the core because it can't reasonably be what you mean.
I think the word is misspelled. It should be folded in the hinges. Indeed, the floating part rests in the hinges when it is lifted. See it as a drawbridge. The supports make the force come from above, with blocks at the top.
Not considered hiring an excavation contractor with a rotating crawler excavator to push down the posts and lift the stone chests and the stones needed with the machine?
Then you build one or two sturdy rafts and do it in the summer
Yes, that's a possibility. Or hire an excavator with a long arm that can pile, lift out stone chests, and fill stones. Wouldn't that work?

A bit unsure about what you're trying to say here. What I meant was that I have most of the tools. But I haven't thought through (yet) what exactly is needed here. But it doesn't matter, that's not where the challenge lies.
All the work necessary for a pier can probably be done if one has a chainsaw and an axe and knows how to handle them. It's possible that an auger or a more modern drill with suitable bits could be helpful if one plans to fasten the stone cribs with heavy iron.
If you want to build a stone crib, it's a suitable example of how it can be done properly. Otherwise, you can put together something simpler without dovetail joints and tie it with thick reinforcing bars, the important thing is that it's thick and sturdy if it should withstand the ice and long-term use, "cheating" with an IBC cage or gabion is a last resort.

Yes, I've read that thread quite carefully. But as I said, the conditions feel different with an excavator coming on a barge.
The stone crib and the stones can be lifted from land if you find a contractor with an appropriate machine.
Build/buy the floating dock first so you have a barge to work from.
Then you have the choice to buy anchors, make anchor stones out of concrete, or drive down pipes to anchor the floating dock at the far end. If you use anchors/anchor stones, cross the lines.

Not quite sure about the OP's situation, but if you get a floating dock to build a stone crib, you have the solution in place with the floating dock.😉
We have two, first a 2m gangway, then a 4*2m floating dock and finally a 3*3m floating dock at the far end.
Exciting!
You don't need an excavator and barge for a stenkista, I've built several completely manually for others.
You have to timber up piece by piece in the water and fill with lagoma stones, small enough so they don't fall out.
But it's a substantial job yet very fun at the same time.
Several firms I've seen also don't make dovetail joints but only use threaded rods.
In your case, a floating dock would probably be the most suitable and cheapest. Especially if you want to get out a bit for the reeds.
A good floating dock can of course withstand being in the ice.
Depending on shore conditions, but if conditions permit, you can easily pull up a floating dock. Use a 12V winch and some old round posts for our two docks. Then in the spring, just secure them with a 2" pipe. Use loops on the sides and poles to hold them in place, much easier to pull up than straight pipes but need to be replaced after 5-10 years.
One of the docks during renovation after about 20-25 years.

The conditions are still a fixed dock section and then possibly a floating dock. Personally, I would rather have a fixed dock in a smaller medium-sized lake, but a higher fixed and a slightly lower but large floating dock is a reasonable compromise. You have something that doesn't move and a part at swimming height with the possibility to detach and go around.
