ABSTRACT:
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.
