Abstract
An improved anchor insert adapted to be embedded in a concrete slab for cooperation with a pick-up unit which includes a locking stem having a pair of lift shoulders extending from opposite sides of the stem, comprises a concrete-excluding hollow cage adapted to be emplaced within a form for a concrete slab for insertion of the locking stem and lift shoulders into the cage after pouring the slab, the cage including a pair of spaced apart shoulders on opposite sides of and spaced from the base of the cage, the shoulders being adapted for interengagement with the lift shoulders and also with a pair of anchor rod sections, and a pair of spaced apart anchor rod sections in such engagement, wherein the locking stem of a pick-up unit may be inserted in the cage and rotated for bringing the lift shoulders into lifting engagement with the cage shoulders, and a lifting force when imparted to the locking stem is transmitted to the anchor rod sections for lifting a slab in which the insert is embedded.
