Hydraulic winch question

[bdog]

I have a rubber tracked crawler that I want to put a hydraulic winch on. It originally was a crawler dump with a tilting dump bed but now it has a fixed flat bed and I now have an unused hydraulic circuit with a control in the cab that used to operate the tilt bed. I checked with the manufacturer and it puts out 11 GPM @ 3000 PSI.

I am a little fuzzy on how hydraulic motors work but doesn't the pressure dictate the torque and the GPM just dictate how fast it turns? The winches I am looking at list in the specs 20 GPM @ 3000 PSI. If I bought one of these would it reach the stated line pull but just be about half as fast? I would not be using it all that often just when I get stuck which doesn't happen that often.

Yes pressure dictates torque & flow dictates speed. Like you state will run a little slower but generate the same line pull

I was going to put a hydraulic winch on my dozer which produces 13.5 GPM at 2000 psi. But when I figured out that it is 13.5 GPM at full throttle and the winch would be deathly slow I got discouraged. Running at about 1500 RPM it would be about 1/2 as fast. For occasional use it would be fine but I wanted something more everyday useful. If you put it on let us know how it turns out.
