I was wandering if anyone have any resources ( Online or books or Excel sheet, etc..) you can share so that i can understand how to size the various parameters of a Hydraulic system for elevator - Rope Hydraulic, Twin Cylinder and Multi Stage Cylinder

Example - Pump HP, working pressure, cylinder size, Rope projection.

The two suppliers i worked with in Canada does all these Calculation. My goal is to educate myself and be able to understand the justification of my suppliers.
