Hammer/Breaker single acting circuit into Double acting 2 way flow conversion?

[BunyipBen]

Hi Guys

I recently purchased a Hyundai R60CR-9 excavator and ordered a log grab and rotator at the same time. I specced the grab and rotator setup for a 4 hose install and recently looked into the hammer piping on the digger and now I am not sure it is a double acting circuit. I have a set of 2 way auxiliary hydraulics that are controlled via a rocker switch on the right joystick and have discovered there is a hammer button on the console that needs to be activated to allow a button under rocker switch to use the hammer. I had been told that it may be possible there is a valve block somewhere that can be turned to make the hammer piping a 2 way circuit but until further investigation I am not so sure this is the case. I am looking for suggestions on the best way to go forward with this setup, I could have ordered the grab and rotator with a solenoid to switch between functions but was hoping that it would be a plug and play scenario with the 4 hoses. I have read into a reversing valve that can be used on the arm to make the single acting circuit dual flow as used with augers. My feelings was that it would be best to utilise the rocker switch on the left joystick so both functions open/close and rotate could be performed at the same time, I am not a person with a lot of knowledge on hydraulics and interested to know what would be involved to go this way. I most likely would not opt for spending tonnes of cash but if I end up with a more desirable install over a cheaper option in may be worth the extra spending. I can upload some photos and will be looking over the machine more this weekend, I may have to tilt the cab to get a better look. Just hoping to get some advice and direction so when it comes to talking with hydraulic specialists I have a better understanding of the situation.

Thanks

We put diverters on the bucket crowd ram to run the rotator on our takeuchi. The hammer line is double acting though so that runs the grab function.

What’s on your joysticks? Roller one side, buttons the other?

 

Looks 4 piped to me, hammer switch basically moves the valve from two way to free return.

The left and right joysticks each have what I would call a thumb rocker switch (proportional?) with two buttons below and a trigger button on the front. I will take some more photos today

I got the cab tilted, no idea what I might be looking for. I think it could do with a wash down, any recommendations on products or techniques to clean up?

Sticker clearly shows the Hammer circuit is two way, and you’ll press the Hammer switch to make it single way operation with free return.

 

I can’t see from the image supplied where the two pipes go from the two quick release fittings paired together on the side of the dipper.

The will either go to the Bucket Ram to Rotate a dangle mount grab or more likely all the way back to the machine for a full rotate circuit.

 

Usually a very quick way to see what you’ve got on any machine, fire it up, put a few revs on and the hydraulic isolator off, then simply roll the rollers and press the buttons, you’ll hear the machine blow off if it’s putting out oil to a circuit and generally see the relevant pipe flex enough to find which it is.
