Abstract
A panel lifting insert to be used in combination with a lifting apparatus to lift pre-cast panels and move them from one point to another. The lifting insert comprises a body with an aperture formed therein which is embedded within the pre-cast panel. Attached to the body are a pair of spaced apart legs with one end of the legs being attached to the body and the second ends being attached to one another to form a U-shaped portion. The legs are curved back upon themselves proximal to the U-shaped portion to form a hook. The hook is used to attach the lifting insert to a segment of a reinforcing means that is embedded within the panel. A lifting attachment is then connected to the aperture in the body to provide a means for connecting a lifting apparatus to the panel lifting insert and thus to the panel itself.
