That should lift my 1500lb logs alright, just not sure my trailer can carry the loader. :laughing:
Any body built a knuckleboom loader

Yep, But i dont plan on going there:duh:
Got my cylinders for the processor this wk. I am going to start the splitter and keep a eye out for parts for the knuckle boom. I have a few other things I have to find as well. I thought I had a 190hp 6068JD engine for really cheap, until I checked it out. Someone had stole the injector pump and the engine is locked down. Motor only had 150hrs on it too. I ran across a injector pump the other day I can get pretty cheap, ( new one is $1900),so i might revisit the engine and see if I can get it to turn over. I also need a 60gpm control valve I have been having a hard time finding used. Also looks like I will have to buy a new 3 section Hydraulic pump. Other than that, I pretty much have every thing else.

What are you looking for in the valve? Just a directional valve? I assume a solenoid operated valve? Voltage? Oc or cc? I can check some surplus at work, can't promise much, but I will give it a shot.

Mike, just a plain Jane open center, spring centering, directional control valve. Would be nice if it had a built in relief. Power beyond not necessary. It would have to be off a pretty big piece of equipment to flow 60gpm at 3000+psi. I could go with solenoid valves, 12 or 24v if thats what I find.

I am curious what will you be running that will need 60GPM?

Twin 4.5x30x2.5shaft cylinders. Cycle time of about 7 seconds. Right at 48 tons to do 12 way splits in up to 27in dia rounds. I plan on a stacked pump, 3 sections, 60/30/6gpm. 60gpm for splitter, 30gpm for saw, and 6gpm for the conveyors and to run the knuckle boom. I am still looking for the pump and a engine to pull it all with. It will take about 190hp to pull the pumps at full capacity, but not everything runs at the same time so i can get by with about 140hp. It takes about 23-27x30 in rounds to make a cord, with a cycle time of 7 seconds, thats a cord every 3 minutes. Of course nothing ever works out like the math says it should, but it should be fast enough to what it needs to do.

when it come to bearings, most bearing are rated at a given RPM, say a axel is 20,000 per wheel that is at 60 to 80 mph,
your loader is turning what one or two RPM, my guess is your bearings will be more than sufficient at that lower speed,
an more than likely al bearing has 3 to 5 times (safety margins in it)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
here is a chart from Timken.com
http://www.timken.com/en-us/product...uments/timken-load-and-speed-ratings-9-10.pdf
there load is rated at 150 rpm and at 50 RPM there load is a 1/3 higher for the most part on the larger bearing it looks even greater, percentage.
think about a good greased steel on steel (pipe/tube on shaft) well greased would handle most any load up unto failure of the components at a few RPM of speed, now speed that same steel on steel system at 200 RPM with even half of the load and it will smoke in seconds.
for the most part I would think your lifting is going to be stationary until you pull the log in close to the trailer and then lift and rotate..
I do not know if you ever lived in farm country and watch harvest, (not so much any more with the semi trucks) but when one and 2 ton trucks were the main work horse, ever truck going down the road was most likely loaded to more than it GWV rating,
I have a old 53 F 500, tone and half ratting, my dad hauled 160/170 bushels of wheat on it all the time, (9000+ pounds of wheat on a 7000 pound truck for a total of 16000+ pounds some times more,
my one ton 10,000 GWV I have had 8 to 10,000 loads on it, and it is a 6500 pound truck 14 to 16000 pounds on the GVW, when I used it for hauling wheat, 130 bushels was normal load 8000 pounds,
what I am trying to say is I really doubt you will have bearing failure if your using a reasonable sized unit ,
