What do these electrics do?

[Dean Lofthouse]

cut one of the wires and see

[Woodworks]

Steering drawbar is on another pair of hoses.

 

Chap I bought it off does not know what it's for.

 

Runs off spools not PTO.

 

No extension on these cranes to my knowledge.

 

Cant see it can be for work light or winch as the wires go into the hydraulic controls.

 

 

 

 

Radio control option now that might make sense.

[njmusk]

Our igland winch had radio control option.

 

The other week could not get the log beak to open, although spools were connected, found that electrical connector had come apart so button on joystick would not work it.

Have a look on website at mowi 650 and scroll down to specs of crane p20, might get an idea from that

Are you sure it not a floating section for the crane turn house and lift cylinder?

Sorry you lost me.

There are 3 wires that go to your grey junction box.

 

Presumably one goes to a 7 pin trailer socket to give you 12volt, maybe when the side lights are on.

 

Presumably two goes to an electric switch on top of one of your joy sticks.

 

Presumably three goes to a solenoid that works one of your spool valves.

 

tomtom is suggesting that operating the electrical switch will pull one (or more) of the spool valves into a float position.This would allow the rotator or main lift ram to float e.g when dragging a bigger stick close enough to lift.

Or when the crane is mounted to a tractor and is 'parked' on the trailer being towed, allowing crane to float as trailer turns/goes up and down hills etc.

That's a more logical reason than my example.

[Breezeblock]

in line with the solenoid on the bottom of the valve block on the side follow the hoses that come off that slice and see where they go that should give you an indication of what its for
