Abstract
A collapsible storage silo having an expanded configuration includes: (a) a shell for circumscribing storage space and comprising a plurality of concentrically nested tubular members that are collapsible; (b) a lift system operable to slidably expand the plurality of concentrically nested tubular members to place the silo in its expanded configuration; and (c) a mast operable to support the lift system, The mast is pivotable between horizontal and vertical positions relative to a frame. A winch attaches to the mast and a cable extends between the winch and an outermost tubular member to expand the silo such that inwardly and outwardly projecting lips of nested members engage each other and a conical hopper engages an innermost tubular member. A flexible inner liner attaches between an outermost tubular member and the hopper. A collapsible roof has a flexible roof membrane and a plurality of radially extending foldable rib members.
