ABSTRACT:
The handle arm of a ratchet winch is convertibly connectible to the ratchet drive lever either to provide a stiff arm swingable conjointly with the ratchet drive lever relative to the winch frame for high-speed operation of the winch, or to provide a pumping arm rockable relative to the ratchet drive lever and engageable with the frame to pry the ratchet drive lever and swing it incrementally relative to the winch frame for high-power operation of the winch. The winch can be anchored by a tie bridging across the winch frame. Wire rope is led onto the winch drum by a traveling fairlead.
