DIY skidding winch build

[Stomper]

Very nicely done all around Stomper. Both the tractor hydraulics and the winch look clean and professional !!! I am also interested in knowing the rope you are using ??

gg

I’m on the rope rescue team at work and the rope is an old rescue rope that was taken out of service several years ago. We take them out of service once they hit 10 years from the in service date. This one has been out of service for quite awhile now so I really can’t remember any spec other than it is half inch and rated for 9200 lbs.

It looks really nice, job well done. Where did you get your third function valve? How do you deal with all the slack rope as you pull in the load?

The third function halve was also purchased from princess auto. 12V DC Tandem Centre DO3 Directional Control Valve | Princess Auto
1-Station D3 Valve Subplate | Princess Auto

As for the slack, it it gets dropped on the ground by my feet.

What is the rope speed? If you timed it, foot per minute maybe.

What are you operating with that 3rd function?

The winch build is nice.

Did you make the rope spool drum or buy it?

I always think of them as a "capstan winch" I see you can buy the drums. Even on Amazone....

Not sure I never timed it but with the tractor at idle the spool rpm is 60 and the spool is 2.25 inch diameter so if you do the math it works out to 35 fpm. With a little throttle I can increase the rpm to go faster.

Third function is for a grapple. The came from a member from another forum but it Is the “portable winch” spool they use on their winches. They are also sold on amazon.

That’s exactly what they are

There have been a few like these built and there has been a few issues that are still being worked out. So I don’t have to go through everything again just go to the below link.

If you do a search in the same forum for members mike Paulson and crmorse you will find their builds as well

The 3rd function valve's page says it's a closed center motor spool valve. It must not really be closed center because your tractor's hydraulics would not work correctly with it plumbed in. If it's motor spool then when it's off the grapple cylinders would be free to move.
