Winch from rear end

[Ole Orange]

I keep seeing posts on here about making a winch from a truck or car rear end. Does any one have pictures or rough plans on how to do this? I really don't want to log with it, but use it to get unstuck from snow or to pull out my plow truck.
Thanks for any input.
PS I want it to go on, or feed from the 3 point

Thanks

I'd be interested to see some examples, too.
There's a Dodge Dakota frame, with it's front & rear axles still attached, out in my woods just lookin' to be put back to work.

Subscribed, sounds interesting.

I saw one once a guy used to pull a wedge through wood on a woodspliter. He ran a tractor PTO to the drive shaft and one wheel had a cable on the rim and the other wheel was removed and allowed to spin freely until the cable was to be pulled then the break was applied to the cable less side stopping it and the cable then spooled up.

That's a great idea - use the differential and the brake to work like a clutch. A strong clutch that can dissipate lots of heat is something that I really want on any winch I build. If you release the brake with the PTO off, the winch line can be spooled out easily. The brake pedal could be operated by a rope to get the operator out of the pull line. Hmmm.

I have read all about these but yet to see one.
Like Baby Grand says they use the brake to help control it as well as some that use the clutch and transmission to differ the speeds
I would like to use a wheel drum and use rope and treat it like the winches the lobster men use. hope some one out there has some pictures to share with us all.

You tube is where I first saw it for loading hay, but I can't seem to find the correct videos. This one shows the axle and small engine running it at the end. I know there are better videos out there.

It looks to have a solid forklift type tire mounted with a friction brake acting on it instead of using the drum brakes on the axle.

How do you disconnect power and reverse?

Thanks all i knew I would find ideas on here I really like the one with the yellow strap just the type i was looking for. If I rember correct I had seen one some where that the drive wheel was driven by applying the brake and when the brake was released it stopped driving it.

OSHA would have a hay day with me.

Just like what I described. On the splitter I saw the cable went to a block and tackle that compressed a return spring and pulled a wedge into the wood. It was lightning quick! Single line master cylinder ran the break.

A look around , it appears that the rear ends out of some BMW autos offers a lot of gearing in a small envelope. This design also simplifys things with flanged input and outputs.

This option does complicate the brake side, detail, as there is no premounted brake carrier.

Another nice thing...they appear to go cheap on ebay or your local wrecker. ($100-$150)

The only problem with using the Brake/Differential action, it doubles the output speed when you brake one side. Your 4:1 diff just became a 2:1.

I have built a lot of winches for the 3pt system. Mostly pto units, but electric and hydraulic ones also.
Using a truck rearend is not the answer. It will way to fast to be usable and unless you shorten the axles as much as possible they will be to far to one side to winch effectively. Your winch needs to pull from centerline of your pulling unit.
I had some winches built with 9.1 gearing. With the 540 pto speed that was plenty fast. If it were me to do it again with just this and that to build with, I would use a bush hog gearbox, post hole digger box as a primary drive and run a sprocket to a drum with a ratchet brake on it. You can drop the ratios by the different sprockets and by putting a ratchet dog/pawl on the other side of the drum you can lock it. When released you should be able to pull the cable out with little effort. Everything would turn includint the driveshaft, but with that little bit of tension it will keep the drum from fouling. Just an idea. Was my next build if I wear out what I have now.

A pic of what I have now, one with boom has an hudraulic unit , the little rig is electric

If one used a truck 4 speed or 5 speed the lowest ratio in 1st gear with a 4.10 rear axle the would be about 10 to one.

yes diesel, that works well as a trailer arch for moving wood. If the hand brake on the back of the tranny is still on it that is a plus. With the gearing in your tranny, the spiders welded solid in the rear end you will get as low a gearing as possible. I would bet it is even lower than ten to one. Love these contraption that get it done.

no it doesnt.

On Perspective

A Farmi winch chain drive is set about 1:4 ratio.

Drum size means a lot !

 

[Roehm Farms]

no it doesnt.

Yes, in an open differential, with a constant input speed, if you stop one axle the spider gears start spinning and the other axle will be spinning at twice the speed it was before.

Just found a video that shows it, if you notice the free axle is turning faster then the carrier and ring gear.
