Two speed capstan
A model of a 2 speed capstan. Once again planetary gears are involved. I'm surprised how ubiquitous they seem to be.
The output ie that which the rope to be hauled is wrapped around, is represented by the planet carrier.
For high speed winding disengage the pawl and wind in a clockwise direction. Engage the pawl and the speed goes down and the torque goes up.
Or, to get a pleasing clicking sound from the pawl and high speed (reversed) winding, turn in a counter clockwise direction.
