Abstract

A bulk bag lifting apparatus includes a structural frame having beams that accept forklifting tines during lifting operations from below and lugs at the top of the frame which facilitate jerking lifts from above. The base has a peripheral side wall that is fixed and structurally connected to the base. A plurality of four moving side wall portions are provided which can collapse upon the base and below the upper edge of the peripheral side wall. In this fashion, a number of different units can be stacked when the units are in a collapsed position. The side walls collapse in pairs including opposed diagonally opposite side walls collapsing at the same time and a pair at a time. In this fashion, a first two of the side walls can collapse into a position upon the base wherein the first two side walls are generally side by side and occupying different half base portions of the base. The second two side walls are also diagonally opposed and are spaced ninety degrees (90.degree.) with respect to the first two collapsing side walls so that the second two side walls collapse upon the first side walls. The second two side walls likewise are diagonally opposite and collapse upon half portions of the base.
