One thing that I did read somewhere, is that there are accumulators in the hydraulic systems that allow it to return to a safe position in the event of a major power failure or fault.
The airline I work for has a couple of 747 simulators, which are nothing to do with me but I've had a look at them and they use a series of large accumulators to allow for violent movement outside of what the hydraulic pump can manage.
As you pointed out above, the basic structure is very similar to a full motion aircraft simulator.

Yes, accumulators are used for several different reasons in hydraulic systems. In your case they do provide extra fluid when the demand of the system exceeds the capacity of the pumps. In other systems they act as pulsation dampeners to smooth out system pressures. There is some interesting info on old water type accumulators used historically in the UK on Wiki.
Several systems on offshore rigs use accumulators, mostly gas over oil types, and mostly as a dampener function.
May you be in heaven half an hour before the devil know`s you`re dead!
^I never knew about this until you mentioned it but I've been having a read and apparently for over a hundred years there was mains hydraulic power available over 150 miles of pipes in London used for operating lifts, cranes etc. https://www.subbrit.org.uk/features/hyd ... in-london/

For most people the mention of hydraulics brings to mind a JCB, or something similar, that uses lubricating types of oil under pressure.
Water has always been the first medium used in hydraulic systems, and in fact is still in use in a lot of instances. Sticking with offshore equipment, subsea hydraulic control systems use fresh water, as it does not polute the ocean in the event of a leak, or even venting as part of a specific function.
