but the question refers to how to model it /design it or its design?
flexlink is a great product, I don't have to say it, but the small widths of their chains would force you to two flanks and therefore to a very complex structure, with problems also in the motorization of the two tracks that would develop different and therefore need different speeds to climb "together". However, with a standard tabletop chain, it is very difficult, in my opinion, to succeed, even using the models, of course, capable of bending, therefore with the lower wings to support it in the return branches. If you have to carry on some boxes I assume you will need a certain width and I don't think they do it more than 254. in any case you would have a diameter of almost a meter and a half (r700+width) and you should climb with a very light angle, otherwise the chain would force too much on the guides. If you consider that for each spire it takes more or less 9 mt of chain (sup branch+return branch), you will see that it immediately arrives at the maximum length that the chain would bear even if it travels banally on the plane. given the little angle of the propeller, you would be able to climb very little, perhaps not even a lap, considering also the two straight lines in the input/output. I do not see it well and I have never seen it in the examples of applications indicated by major manufacturers, e.g. rexnord
there should be more suitable modular chains and you can try in the vast (also too...) intralox catalog.
However, commercial spiralveyors use carpets, not chains. I had found it pretty good of a Dutchman (I can find the name if you want) because I had to climb 5 m from one floor to another. then I solved it with a long tilted tape attached to the wall....but drawing it and making it work is much easier than buying it.... ?
