Good evening to all

I need to take a doubt

I have a double effect telescopic cylinder with 60mm alesaggi for the first torch and 40mm the second torch
works vertically to lift a load
first opens the alesaggio 60 edge then the other
fixed working pressure at 100 bar maximum lifting force available on the entire run of the two swires is equivalent to that of a
cylinder with alesage equal to the smallest edge (40mm) while in the stroke where the first sfilò works there would be a greater force according to the 60mm

Is something right or wrong?

thanks in advance to those who will answer and a thousand wishes of good holidays! !

is correct. That's how it works!
attention that, constant oil flow, the output speed varies according to the alignment (and therefore of which vent is working)

That's correct. the telescopic cylinder has greater strength as soon as it parades with the maximum alignment and then works with the smaller allotment, so much that they are used to compact the pantograph lifts and win the high point force at the start.

Thank you so much!!

I have another doubt always on the double effect telescopic cylinder:
when I test it with a control unit equipped with a pump with abundant flow known that before you parade the biggest vent then when this goes to the end of the race part the small vent as I expected happened.
If I connect it instead to a control unit with a pump with a very lower flow it happens that first start the small vent... How come this difference? Does anyone have similar experiences?
