Re: lift winch ideas anyone?
You could use a differential windlass principle for a winch. It's easy to get a tremendous mechanical advantage if you don't mind using quite a bit of cord. Search on "differential windlass" or "Chinese windlass". Same principle is used in chain hoists (chain falls). It might eliminate all the heavy, expensive gearboxes.
Oh, perhaps someone can figure out how to use this 33:1 torque multiplier in a winch application:
