Abstract

A lifting apparatus for use in lifting a concrete or other structure including a first member for inserting into a wall of the structure and a second member for fitting onto a forklift and engaging the first member. The first member includes an elongate member encased in a polymeric material. One or more resilient radial fins extend from the first member, and are angled away from the first end of the first member. A pair of raised shoulders define a circumferential channel near the second end. The first member is installed in the structure by being driven into a preformed hole in the structure. The second member includes a hollow body for sliding onto a forklift tine, and a side wall having at least one vertical recess for receiving the circumferential channel of the first member.
