Rotator stopped rotating

[Al Cormack]

On the clamshell I have, it stopped rotating earlier today. Was working ok, then wasn't

 

 

 

Doesn't look like you can get inside it?

 

Any ideas?

 

Cheers...Al.

Have you taken the two hoses off that go into the rotator and checked the hydraulic flow? 

I assume from the pictures to take it apart you want to pull the pin that holds it to the clamshell and there should be a way in from the bottom.

Thanks mate. I'll check it out soon.

Al you can check/eliminate the rotator if you put it back on the crane and connect up one pipe,   take  the quick release coupling off the other pipe and shove that into a drum, pull whatever lever ( one way or the other) that you use to rotate and fluid will either pump straight through the rotator (fecked) or it will rotate indicating something wrong with the crane hydraulics or a coupling fault .

Cheers Bob. I'll check it out when I've got a spare 10 mins. It's not the lorry hydraulics as timber grab  works fine.

Its definitely something wrong with the rotator. Oil flow is fine, and hydraulics work. I'll see if it comes apart and have look see.

Havent had a chance to investigate further Mark. It works well enough free swinging at the moment.
