  • Patent number: 4621972
    Abstract: A silo mover apparatus comprising a main frame that is movable across the ground on a plurality of support wheels, and which has a subframe pivotallymounted thereon adjacent one end. The subframe can be raised about the pivot to a substantially vertical position through the use of hydraulic cylinders, stabilized in position adjacent to a silo to be moved, clamped to the silo by straps, after the silo has been suitably reinforced, and then the silo can be lifted and tilted downwardly with the subframe to rest on the main frame for transport to a new location. At the new location the silo is then raised by raising the subframe about its pivot, to place the silo onto the desired platform, after which the members that clamp the silo and subframe together are removed.
