Re: CAT 535C Grapple Skidder
 

Were would I get a electrical slip ring. I had run this through my mind but not sure how to make the actuator operate in two directions?

I love to have someone machine me a knuckle/swivel.

Thanks for the ideas.

Oh wow, that is slick. Thanks

Still can't figure out how to make it a powered rotation so, it will rotate freely.

Made some progress and I Muggy welded with great success..wooohoo!!!!!!!
The parts I "welded" are the lower parts of the knuckle- two pieces of channel back-to-back. Sweet!! I am happy with the articulation of it, turned out real nice for me. Man I need some hydraulics!!!!!!!!!!

Re: CAT 535C Grapple Skidder
 

Looks great, should be fun to operate.

Re: CAT 535C Grapple Skidder
 

That is looking really good.

wow real nice build
where are you going to get the Hydraulics from?
and do you have a website for them

Re: CAT 535C Grapple Skidder
 

PMD if they ever come in!!!

Re: CAT 535C Grapple Skidder
 

Very nice machine, any idea how much time you have in it so far?

Re: CAT 535C Grapple Skidder
 

Looks good Ben

I see a lowbed in your future. lol

Ben, Your Skidder is looking good, With the Hydraulics and a little paint you will be ready for the woods. Next build? Fred

Re: CAT 535C Grapple Skidder
 

That is looking real nice!

Re: CAT 535C Grapple Skidder
 

Next build will be a lowboy for sure, at the rate of hydro's coming available, I will probably have the trailer done before they arrive.

I thought Leimbach sold one but from memory it was pretty expensive. DSTI makes some hydraulic slip rings. I have no idea what they cost or if they would work in this application.

I have thought about how to make the swivel as well (for a long term skidder project of my own). I think you might be able to use some fins to turn the swivel housing with a hydro line into each side of the housing where the lines enter at an angle to push the fins with the fluid. Of course you would need some gears in there to do the actual turning and you would have to limit the rotation so your hoses to the grapple wouldn't get twisted. To do a true 360 degree swivel you would need to have a hydro slip ring for the grapple hoses.

Not sure how it could be done but one day maybe I'll give it a try.

Re: CAT 535C Grapple Skidder
 

Forgot to add, the skidder looks great!

Re: CAT 535C Grapple Skidder
 

Man,This looks great! You called me the expert? If mine looks half this good,I'll be a happy Guy! Real nice job on the grapple!
Don't know how much room you have left,but the hydraulics will take up a bunch of it. Don't know if you have seen the mini pumps from stahl. It only took 15 months for me to get it. Guess ole-Ric babe is havin problems getting stuff from Germany. But it's very small & has a brushless motor(reversable) & you can set the rpm on it so your not making a bunch of heat running the pump wide open for nothing. Another draw back on the mini is the price!You can buy two regular pumps for the price of one mini.
If you want I'll post some pics of the differance between the two pumps.
Keep up the good work!
