Abstract
A lifting mechanism for a concrete structure is provided through means of a void former and anchor assembly which it cast in place to provide an accurate recess in the structure having two or more spaced divergent anchors therein. The anchors define annularly aligned apertures within the recess. A lifting shackle of an arcuate configuration complimental with that of the recess is received within the recess and carries an arcuate locking bolt extendable through the aligned apertures.
