摘要： The present invention provides novel lifting devices and methods for lifting foundations and slabs. One or more power cylinders is pivotally linked to a pier and to a foundation bracket assembly. The pivotal linkage results in self-alignment between the longitudinal axis of the pier and the axis along which compressive pressure is applied to the pier.
