  • Patent number: 5339996
    Abstract: A portable mini silo system for delivering dry mortar blends to batch mixers is disclosed. Such system includes a silo that is constructed for portable transport to a construction site, while providing support for the silo at the construction site, through the use of telescopic leg elements. The telescopic leg elements are suitably reinforced and mounted to the silo to provide both lateral offset and reinforcement. A collapsible ladder is attached to one of the telescopic leg elements for collapse and extension as one of the leg elements is collapsed and extended. The collapsible ladder, when extended at a construction site, enables a user to load dry mortar blends into the silo. A platform is also attached to the silo side wall and cooperates with the collapsible ladder to enable a user to climb the ladder and stand on the platform, thus facilitate loading and checking the contents of the silo.
