1. An automatic take-up winch comprising:

  • a reel element mounted for rotation about an axis and about which an elongated flexible member is to be wound;

    a ratchet mechanism permitting rotation of said reel element in a take-up direction through a series of different positions and adapted to releasably prevent rotation of said element in a reverse unwinding direction from said different positions; and

    a power unit including a power actuated part operable upon movement in one direction to turn said reel element in said take-up direction from one of said positions to another;

    said part then being retractable in an opposite direction relative to said reel element in preparation for another take-up step, while the reel element is retained by said ratchet mechanism against rotation in said unwinding direction;

    said power actuated part being automatically operated to wind said flexible member to a desired tension when said part senses a slack condition in said flexible member.
