double pantograph force scheme

[Fandrix]

Hello everyone and good evening. I have a doubt about the scheme of forces in order to maintain the balance and obtain the strength of the cylinder. I have already searched on the forum and found many interesting things and I compared a little with my work. I made a system of equations from the various elements looking in red the unknown. I want to compare with someone to see if the process I'm doing, or to solve an equaziniu system made up of all those proceeds, was the right way. Thank you for your patience.

patience you only used and all of you, since no one so far has answered you.
Of course you have done a lot of calculations and operations, but what is missing in the project is the schema of operation, applied force and where, because double pantograph, fundamental measures, what is needed, etc.
better be more synthetic but complete.
