I fitted a changeover valve on the dipper of my Yanmar, into the bucket crowd service.

The solenoid pokes out through a convenient hole, so I fabbed a cover and threaded a few holes and bolted it on.

It's activated by a button on the left joystick, providing full proportional control of the circuit via the right joystick.

I use it for the rotator and it's a joy to use.

 

That's a handy diverter. Are the hydraulic lines for the rotator on top of the valve there. Is it a quick release coupling system or do you have to take the spanners out when you remove the grab. Also are the electric circuit type you have better then the manual type. Presumably more convenient from the cab.

Where did that valve come from? Cheers.

Few shots of a Doosan with a Woodcracker treeshear rotator head on it from yesterday's job.

Awesome!

I thought you would like it Stephen...

14 ton machine so compact with no overhanging rear...

[Breezeblock]

cool that looks quite a well built shear i would like to sees that in action

[rowan lee]

Good shots Silky.

The valve is a 12V 3/8" Badestnost DVS6-6/2L:

Yep, the services for the crowd ram pass through the body the valve and the diverted services to the rotator (in my case) are out the top.

 

It almost bolted straight into position, except I had to file the holes in the hose mount bracket on the dipper a tiny bit to let it all line up nicely.

Using suitable connectors, all the original hoses on the machine re-fitted without modification.

 

I also milled a few millimeters off an edge of the valve (opposite end from the solenoid) to allow it fit neatly into position on the dipper.

 

The new auxiliary hoses duck under the end of the crowd ram and appear out the side of the dipper and terminate under the original rock-breaker hose ends.

I got them made up slightly too short, so the bends in them are a little tighter than I'd like, but they appear to be working fine for the last year or so.

 

They all terminate in flat-face quick couplings.

 

The diverter is operated by means of a push button on the left joystick.

Its default position (unenergised) leaves the crowd ram work normally.

Energised (button pushed), the service is switched to the new hoses, giving full proportional control of whatever tool is out there.

 

I can't crowd AND rotate (in my case) simultaneously, but I haven't found that to be an issue.

Thanks for the info, Seems nice and simple, and relatively easy to install.
