Could one use a stainless Rectangular beam with dimensions 12 cm + 5 cm all around. That is, remove the wooden frame. ???E Erik Lindroos said:
Now I understand! Please continue to "nag." I don't think that solution would work as I would have quite large wheels around the pool deck both when it is open and closed.O o5kar said:

Well then, I just sympathize with you for spending 40k on pier reinforcement, since it might as well be hanging down until it needs to go over the edge of the pool 
!
I was thinking of 1 wheel in the middle, but you might need several, so start with one, why don't you.
Look for something like Ottoman-wheels for industry that can handle a lot of weight. They can preferably be a bit larger so the rolling function doesn't mess up, so you lower them into the boards. As long as the wheels are firmly attached, and the rails on the dock are firmly attached, it's enough if 10mm protrudes above the deck.

A completely new idea. Would then remove the rails from the deck. But at the same time, it probably won't help against the flex in the deck/frame, which is the big problem. The sheet metal must be attached to something.
Need to eliminate the sway in the middle of the deck as well as the long sides...

Well, this isn't super well thought out from my side. And I'm just a happy amateur. But I'm thinking that the sheet should basically take the entire load, so the edge doesn't need to be super strong (as long as you don't place a large point load there, for some unknown reason to me). The images illustrate how I would spontaneously imagine it.Huggedugge1 said:
The advantage of high-profile sheets is that they are made for long spans and outdoor use. They manage on their own. The disadvantage is that the adaptation to the surroundings can be a bit tricky. It concerns corrosion considering the pressure-treated wood and endings and fastenings that aren't like a regular roof.
So others are welcome to critique. The simplicity of the proposal with edge wheels should not be underestimated as long as the rest of the construction holds.
Need to think. Must know which frame I should use.
I probably explain as poorly as a rake, but the new recessed wheels are only meant to complement the existing solution. The sole purpose is to compensate for the sag at the end of the uncovering process when the bridge approaches the pool edge. This solves the wobble in the bridge, and if you also have wobble in the decking around the pool, you will need to fix support pillars to the ground under the recessed wheels.
To achieve the greatest possible load-bearing capacity on the beam, you want to have as much mass as possible as far away from the center of rotation as possible...
This can be achieved by taking a regular tube and welding additional material to the bottom and top...
And also pre-bending/over-arching/pre-stressing the beam in an upward arc...
All this is complicated by the fact that the construction is essentially already finished, but it's not impossible...

So there is no misunderstanding: is the problem that when the pool cover is partially open, the free long side hangs down so much that it becomes an issue when approaching the fully open position and the cover's long side needs to get back on the edge again?
When the cover is fully open or fully closed, it has support along all four sides and everything is fine?

Now it would probably be best if @Huggedugge1 responds, but if the cover comes over the edge on the far side but not on the mezzanine side, then I definitely don't understand how that works.Bernieberg said:
No, that's true, it should be the same problem when closing. Awaiting the solutionE Erik Lindroos said:
Have you already tried with an IPE 10 spanning 840 cm?
But definitely good to have clarification, especially if you are considering a solution with edge wheels.No, that's true, it should be the same problem when closing. Awaiting the answer key
Yes, then it should also scrape on the way out.
Yes. But about 850 cm free. To the terrace that the deck goes under. Had to weld two IPE beams together and box them in with 4 mm corten steel plate. Deflects 3.5 cm despite that.D Derbyboy said:
