Abstract: A storage silo for storing granular material has a container supported by a base, the container having a roof and at least one side wall for defining a storage space beneath the roof. The storage silo includes: (a) a feed port for receiving the granular material at a feed-port height lower than the roof; (b) an auger for moving the granular material toward the roof within the storage space, the auger receiving the granular material via the feed port; and (c) first and second auger motors for cooperatively driving the auger, the first and second auger motors being disposed at opposing ends of the auger. A processor determines power levels for the first and second auger motors to minimize torsional strain on the auger. Granular material can be discharged from a first storage silo into a second storage silo positioned for cascading with the first storage silo.

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.

Abstract: A portable storage bin includes a base frame on the ground and a bin support frame operable relative to the base frame between a working position and a transport position which is reduced in height relative to the working position, and a storage envelope supported on the bin support frame to define a storage chamber for storing particulate material therein in the working position of the bin support frame in which the storage envelope is collapsible with the bin support frame from the working position to the transport position. The bin support frame has an upper frame portion from which the storage envelope is suspended in the working position and a central support post which is extendable in height between the upper frame portion and the base frame for raising the envelope from the transport position to the working position.
