Logging winch design

[tslbogger]

Having something for the logs to snag on can be a pain

Never think about this one.

I will check how I can mount it flush and keep some strenght .

Keep it low too - so you don't lose any ground clearance. This is what I did.

Made like the yellow one works real good. Forney is good too.

Waiting for that hydraulic winch to spool in will try one's patience.
That's a problem with recovery / hoisting winches. If it's got the guts, it's too slow.

pto versions really are best. Like the commercial units.

And I'm not sure a good logging winch can be built for less than it can be purchased for. Cost per pound etc.

I have a tajfun 10000 lb pull hydraulic powered by PTO it is fast about a foot every two seconds

I would look at your cable path routing. As the block pivots will it drag the cable off the upper pulley? I know you would normally be trying to winch directly behind the tractor, but if you go for that one last tree off to the side will your cable jump off track.

You mean the cable could get out of the second sheave when doing side pulling?

Norse winches are built this way. Maybe I miss a detail about their sheaves configuration.

I'm pretty confident the cable will stay put. I add a swivel cable guide to help the loose cable follow the right path.

I was thinking more of it jumping off the top sheave. It seems like subtle changes in sheave groove depth, pivot points and distance between sheaves could have significant impact. Just something to watch and think about.

I do know it can get ugly when a cable comes off a sheave and wedges itself in place it was not meant to go. Had that happen on a self releasing snatch block.

One other item you might consider in your design, is a place to hang your chokers.

If this is what happened to your SRSB then as you can see I had the same problem. Others running small diameter cable have reported the same thing.

I took a short piece of rod and bent it. Then braised/welded it onto the the block. Problem solved.

Just something you can try if the problem continues.

I will make the groove deeper and wider to help keeping the cable in the sheave.

And maybe add a piece of steel to be sure the cable cant go between the sheave and the housing like Gordon Gould does

So, 30 FPM. That's slow by logging winch standards. My logging winch runs at 180 FPM with the spool half full, if my PTO is running at 540 RPM. I normally don't run that fast. 120-150 FPM is probably typical for me.
