  • Patent number: 4432306
    Abstract: Apparatus for lifting a down cow or other like animal. This invention comprises a frame having four vertical legs connected by an array of cross members. The legs and cross members include tubing of similar shape, but of different cross-sectional dimension so that elements of the frame may be hand-carried to a down animal and easily assembled in sliding fit engagement without tools. Two winches each connected to one end of a sling and to the frame are provided to lift the front portion of the animal. A hip clamp adjusted to engage the animal's pelvic bones and a hoist connected to a cross member lift the animal's hind quarters.
