Slip rings for hydraulic controller?

[Jpflex]

Has anyone come across this type of electrical control for a hydraulic outriggers (construction vehicle)

Several toggle switches route 12 volts dc battery power to brushes sliding on slip rings to control direction of hydraulic fluid to control outriggers for heavy equipment tractor.

A single Voltage is spiced to surround each slip ring controller by toggle switch such as right rear outrigger out or in.

I assume ground is through vehicle chassis

I was wandering if this would be the field to turn a possible rotor but what about the necessary commutator for dc?

Has anyone ever come across a control system such as this? She picture

My guess is that it’s feeding solenoid-operated hydraulic valves.

How far did you go while "wandering" ?
(Devil makes me do it )

That’s a good thought but I haven’t figured out why it would need to be done this way or rotated to only feed solenoids

Yeah on construction equipment where the cab/operator's station can rotate 360 degrees. Much cheaper to use a slip ring and solenoid valves than to do it with straight up hydraulics

Yes indeed this makes sense. However should not voltage be going to solenoids on other side of slip rigs?

Yes when the operator selects that function. What are we talking about here, a crane? Manlift?

Update I found only 2 tenths of a volt returning from underneath opposite of slip ring input 12 volts so it looks like a turret issue so far
