ABSTRACT:
A hoisting anchor assembly to be embedded in a cast panel member of the type used as prefabricated building components. The anchor assembly includes an anchor head for receiving a hoisting unit such as a lifting shakle. The anchor head is retained within the panel member by an anchor in the form of an arcuate rod having a 180 degree bend with both ends of the rod being rigidly secured to the anchor head. The panel member is fabricated by horizontally casting a bottom panel section and positioning at least two of the anchor assemblies over the bottom panel section in a spaced-apart relationship with the anchor heads being disposed adjacent the position where the end of the panel section will be formed. A top panel section and a plurality of spaced-apart web sections are then cast over the bottom panel section, with the anchor assemblies being embedded in the web sections. A portion of the web sections are then removed so as to expose the anchor heads so that hoisting units may be attached to the recessed heads.
