ABSTRACT:
A sow lifter includes a vacuum hood with a gasket which establishes a seal between the hood and a sow to be lifted from a mold. Preferably, the gasket is of a circular cross section before use and includes a core of a first material surrounded by a high temperature resistant fabric. The gasket is detachably mounted to the vacuum hood. A sow gripper may be provided and may take the form of fluid cylinder actuated arms with sow gripping elements. The gripping elements are shiftable from a first position in which the elements are not positioned beneath a lifted sow to a second position in which the gripping elements are at least partially positioned beneath the sow. The sow lifter is preferably utilized in combination with a sow train to facilitate the cyclical removal of at least partially solidified sows from cars or molds in the train as such molds pass a sow removal location.
