Because the chances of actually needing a winch are pretty slim, I’ve decided I’d like to go inexpensive when it comes to winches. I originally was thinking of the Badland Apex winch, but the 12,000 pound quadratec which seems to be a goodbye as well. My concern is that the Badland winch is rated at 6 hp and the quadratec is only rated at 4.9. Is the horsepower difference really that big of a deal When it all gets gear down anyway?

And as long as were on the subject, has anybody got any real life experience with the quadratec line of winches?

No I don’t think the horsepower matters that much. It’s the torque of the motors that really matter anyway and they do not give us those numbers. Besides, as you said, the almost 300:1 gear reduction in today’s winches should be plenty.

no experience with the quadratic winches but the Apex was much better made than I expected for the price when I installed it two weeks ago.

Do you mind sharing what mounting plate you used?

Isn’t HP a function of torque and speed? So a higher HP motor will reel in faster?
But I think torque is all that really matters. Maybe power draw will correlate to HP.

HP is more a function of torque and the revolutions per minute of the motor/engine, though in reality it’s more complicated than that.
An easy way to see it is by this equation:
HP = Torque x rpm/5252,
where HP is horsepower, Torque is pound-feet, rpm is how fast the engine is spinning, and 5252 is a constant.

So yes in order to speed up the winch without lowering the 300:1 gear ratio, the electric motor inside the winch would need to have more HP while retaining its original torque value, which basically means it needs to spin fastr

Old thread and maybe some old misconceptions.

With a winch, we are primarily concerned with how much force it will generate to pull the rope/cable. The makers conveniently give us a number i.e. 10,000 lbs, 12,000 lbs, etc.. This is a result of the torque of the motor output (a force at a standardized radius lbs/in, lbs/ft, N/m, etc.), mulitplied by the gear reduction (gear reduction is a torque multiplier) and altered by the line spool radius. But all we need is in the winch load rating....almost.

If you're talking winches, eventually the term "line speed" will come up. When you combine the winch rating with line speed, you are talking about how much work can be done in a given time. That is the definition of horsepower.

So, if we have two winches rated at 10,000 lbs, they will both pull as hard as one another. But, if one has more horsepower, it will pull that same force with a higher line speed. If you have a 4 horsepower 10,000 lb winch and an 8 horsepower 10,000 lb winch, the 8 horsepower winch will pull 10,000 lbs twice as fast.

A winch rating and motor torque are both force measurements that don't consider movement.

When you want to know how much time it will take a winch to pull 10,000 lbs of force XX feet, you are posing a question of horsepower.
