Abstract

A method of breakdown hoist for breaking down a stack of tiered material has an inclined face with upper and lower edges, the stack of tiered material translatable over the inclined face between the upper and lower edges, a supporting frame supporting the inclined face, a rotatable stack receiving cradle for receiving the stack of tiered material from a stack transfer device and rotating the stack of tiered material into slidable engagement with the inclined face, a translatable hoist arm translatable along the inclined face for translating the stack of tiered material between the upper edge and the lower edge in a direction towards the upper edge on the inclined face, and means for translating the translatable hoist arm along the inclined face, the hoist arm rotatable between a recessed position recessed beneath the inclined face and a stack translat-ing position substantially perpendicular to the inclined face, whereby when in the stack translating position the hoist arm may engage an underside surface of the stack of tiered material and slide the stack of tiered material over the inclined face towards the upper edge of the inclined face so as to deposit the tiered material over the upper edge.
