An apparatus for signaling rotation of a winch in which a rotating gear internal in the winch turns an optical disc with alternating segments of distinguishing features. The disc is then in turn read by an optical sensor that can generate a pulsed output signal based on the travel of the alternating segments on the disc. The output signal of the optical sensor is then conditioned to drive a solenoid that is placed in a control lever of the winch. The optical disc and the optical sensor are part of a self-contained unit which can be inserted internally into the winch housing.

Apparatus for signaling rotation of a winch to an operator thereof

A method and apparatus for indicating when only a given minimum preset number of winding layers are present on a drum of a winch. An optical sensor system is included in a space in a hollow housing to count the number of revolutions of the drum and the direction of rotation to produce an alarm signal when only the minimum number of winding layers remains on the drum.
