winch driveshaft speed

[Big Mike's Motor Pool]

i have a spare deuce winch. i recently bought a gooseneck trailer and i would like to put the deuce winch on it. problem is my trailer doesnt have a multifuel and a spicer 3035 with pto to run my winch at work i have a hydraulic head thats 12vDC that i can have. i want to couple a hydraulic motor to my deuce winch for the trailer but i need to know how many rpm the winch shaft spins. i know it can be variable speed, but whats the minimum required to operate the winch to its potential. it would be much easier to just put an electric winch on it but im maiking the ramps hydraulic also so why not the winch LOL

I think this is basically how the A3 winches work...same winch, but with a hyrdo motor on it instead of the PTO (powered off of the engine of course).

Maybe some research there would point you in the right direction...

With the 3053 tranny and the engine @ 1000rpm the winch drive shaft (viewed from front) turns:

CW, at 650rpm in LOW

CW, at 1463rpm in HIGH

CCW, at 975rpm in REVERSE


Maybe this helps as reference.

As long as the required input torque is available, the winch will still pull the same amount at a lower D/S RPM. It will just take more time to pull. - IE line speed.

thanks gerhard, that helps alot. any ideas for toque guys?? if i get somthing a little slower it wont bother me.

It wouldn't be too hard to mount a chain and sprockets between the winch and hyd. motor for more speed or power ( depending on witch you need).

Mike, look at this scheme: without counting losses from brake drag and friction, (theoretically) to achieve a force of 10000 pound and with 4 to 5 layers of cable on the drum (estimated r=4") we needed about 3300ft/pound of torque directly at the drum!
Now the worm gear reduction ratio of our Garwoods is 23:1, so that would make 145+ ft/lb at the driveshaft., which still sounds like a lot...!
But I doubt you would ever need that much on that trailer...?!

Thanks for the great info gentlemen, this will help with my switching from PTO to Hydraulic powered winch on my M35A2, I've been told the torque needs to be around 1,000 in/lbs

1,000 inch pounds sounds quite low. did they mean foot pounds?
I used a winch on a machinery hauling shop truck that was similar to the deuce winches that had a hydraulic motor, specifications unknown, driven by the same PTO pump that ran the tilt bed. The motor had a small sprocket on it, probably about 16 teeth while the winch had about a 40 tooth sprocket on it. It would drag the truck backwards.
