  • Patent number: 5188247
    Abstract: A lifting apparatus that permits an object to be precisely lifted in a highly safe manner along a number of selected paths. The object to be lifted can be vertically raised along selected transversely spaced paths by vertically raising the lifting arms of the apparatus and can alternatively, or simultaneously, be pivotably lifted by imparting a pivotal, upward movement of the lifting arms relative to the base assembly. The cable or chain which actually lifts the engine is connected to a carriage that reciprocates along tracks which transversely span the lifting arms. In this way the lifting path can be varied either to the right or left.
