A lifting bracket and associated lifting bracket system for mounting on an anchor pier for lifting generally horizontal building supports such as foundations, wherein the lifting bracket includes, collectively, a lifting plate, a gusset plate and a slide collar. The slide collar may be elongate and sized to fit snugly over an exposed upper end of the anchor pier for sliding engagement thereon. The lifting plate is mounted to the slide collar so as to extend cantilevered in a first direction substantially orthogonally therefrom, and so as to leave at least an upper portion of the slide collar extending upwardly from the lifting plate. The gusset plate is rigidly mounted at a lower edge thereof to an upper surface of the lifting plate so as to extend substantially entirely across the lifting plate in a second direction substantially orthogonal to the first direction, and is rigidly mounted at at least an upper portion thereof to the upper portion of the slide collar disposed above the lifting plate. The gusset plate extends rigidly from at least the upper portion of the slide collar to the lifting plate.
