Abstract
A lifting method and device. A first lifting device lifts a multi-layer stack of articles from a lower position upwardly to a raised position at which the uppermost layer is at a desired level for removal of articles. The first lifting device continues to move the stack upwardly in increments for subsequent removal of articles in subsequent layers at the desired level. A second lifting device engages the bottom of the stack at locations different from the areas engaged by the first lifting device for continuing upward movement of the stack for positioning the remaining layers at the desired level for the removal of articles therefrom. The first lifting device is then movable downwardly to receive a new stack and the second lifting means is foldable to a retracted position and movable to a position below the new stack.
