6 way valve for log/rotaor grab

Is it a chipper, is it a mower or another broken stump grinder who cares we'll fix it!

so you would use the bucket crowd circuit for rotation this is a really poor idea and never gets done by manufacturers as they have buttons in the joysticks for rotation if the grabs too fast at rotting fit a restrictor in the feed to the valve

 

Why wouldn't you tee off from the crowd ram to give you an easily controllable, servo operated rotation? Leaving a two way auxillary to open and shut the grab.

 

An LGP Eddie setup with proportional rollers on the joystick and variable flow rates would be lovely. Not gonna happen for the OP- he needs the best way to do it with what he's got.

 

In the end, it really doesn't matter. All the OP needs to do is install a t-piece leading to an aux port on both crowd ram lines, and a tap on one side. Then he can try using it both ways (foot pedal to rotate or servos to rotate) and come back and tell us which he prefers.

 

OP- are you sure the extra pipe is for a quick hitch? If it's larger diameter than the others, it's most likely a case drain line.

What sugestions or ideas to you have adding a 2 nd aux hydraulic circuit??

 

You talk like you are very clued up but im not seen any sugestions or is this a private joke bewteen you and breezeblock !!?

 

Yo Pedrod,

 

We use the bucket ram oil for the rotator (mainly because it's this way on our other machine's joystick- botex roof mount).

 

There's a solenoid operated 2 way valve mounted on the boom where the bucket ram oil hoses have connector. This has 6 ports. 2 from valve bank, 2 going back to bucket ram steel pipes, 2 off to rotator (through flow restrictor) these 2 hoses run down one side of dipper as our rotator has ports this way.

 

The rotate function is controllable, maybe still set a little fast, but ours is 8t.

 

The grab is run off the aux. From where the foot pedal was, although we complicated this a bit by putting another solenoid down there instead meaning our grab is run from 2 finger button, and is a bit jerky. Foot valve more controllable smooth-wise.

 

The 2 grab hoses run down other side of dipper.

 

Basically we added one new hose down each side, but reconnected them at the beginning to get the aux all on one side, and the rotator oil on the other. This means we have nothing crossing over down by the grab!

 

While I've seen machines plumbed in every different way, it seemed logical to me at the time to fix ours this way. The other factor is that if you put the grab on the bucket oil it is too easy to let go of log in mid swing!

 

Cheers, John.

Oh, pedrod, the 2 way valve we have for diverting the bucket ram oil is electric for the use we have, you'd be better with two times 2-way valves (3port) with the handle you can crank over which way you want, or a "T" and a tap on the bucket ram side as someone rightly said. I've not seen a 2-way six port that's hand operated, might be available, don't know.

Ours is electric solenoid for another function and it's a complication you probably don't need!

Use the 2pipes from the crowd ram plug into 6way diverted valve,then2 pipes for rotator and 2 for the grab.run the power cable back to the cab and have a little thumb rocker switch on your right hand joystick use this to switch between grab and rotate simpler.

Flowfit do a 6 way change over valve which is 2 x 3 way bolted on top of each other. Part # 7003.0101 for a 1/2" BSP one.

hey Callum, that's answer right there!:-)

Eh!

Derp!

This is news/newsworthy?

bog standard arrangment on tractor loaders for the "third" service, generally to power a silage grab.
