Hydraulic Damper

[BEMPE16524]

Hello Guys,

I need some help. This photo is showing a dampener system (hydraulic cylinder and double accumulators).

SWL of the system is 50 Ton.

The movement of the pivoted point is very minor (I think not more than 3 degrees).

So, I am not familiar with the system, do you know if there is any type of valves that is needed to be attached to the cylinder for the damper also?
Also, what type of hydraulic cylinder is that? I saw one side of the rod already corroded (not sure if that side is also for working) or maybe it is covered by Denso tape?.
If you can give me a link to the supplier I will be really appreciate.

Thanks in advance.

in addition, I don't have any hydraulic diagram of the system also.

I think I have to create the system from scratch. so I have this diagram, but still in doubt about the hydraulic cylinder configuration. not sure if the spring in the cylinder is still necessary. Any idea would be appreciated.
