Hydraulic Motor, High Torque, Low Speed

[butelja]

I have an application requiring a hydraulic motor that will deliver 5,000 to 6,000 ft*lbf of torque at 10 to 20 RPM. Does anyone have experience with any specific manufacturers (Hagglunds, etc.) of hydraulic motors in this size range?

Try Rexroth wheel and winch motors
model MCR15 large frame motors 105-140 HP

the characteristics of the MCR15F1500
min rpm: 3
max rpm: 150
max gpm : 59.7
max hp : 140
rated torque : 4425
peak torque : 7325

momentary peak torque at 6000 psi

What does "low speed, high torque" mean exactly? ... or similarly, "high speed, low torque"... are there numbers that are standard for these descriptions (is "low torque" from zero to 1000 lb-ft for example?), or are these just "feel" words? I don't like feel words.. I want numbers!!

Sorry for being a bit off topic..

Please forgive me, I'm just a beginner...

Thanks
