Abstract

One embodiment of the present invention describes a lifting system (20) for hoisting heavy pre-cast panels includes an anchor-lifting device (22) permanently secured within a connection recess formed in the panel, and a connecting apparatus that attaches to the anchor-lifting device. The anchor-lifting device (22) presents a laterally disposed connection pin (38) for attachment to a pair of laterally spaced lifting hooks (52,54) that form the connecting apparatus. Another embodiment of the present invention describes a removable and reusable insert (110) for positioning and supporting a lifting system (200) within a panel to be formed from cast concrete, the insert assembly (110) having a left and right portion (131,133) which are detachably removable from each other, and a lid (112) that is secured over the insert. The lid (112) protects an interior space of the insert assembly.
