Abstract
An animal lifting mechanism for lifting the rear quarters of a lying cow or the like animal. An angle adjustable yoke has cushioned gripping arms disposed angularly inward. The yoke's included angle is adjusted by a pivoting crank with a hook attached to one of the arms of the yoke. The other yoke arm anchors a chain for engagement with the hook for the adjustment of the yoke angle which is dependent on the size of the animal. The apex of the angled yoke has a rotatable ring which is adapted to be attached to a lifting chain.
