Abstract: A silo and elevator structure disposed in a folded-up arrangement on a trailer bed. Specific ground supports are first installed between the silo legs and ground level, the supports are specifically designed to carry the silo and also the elevator loads during erection procedures and remain part of the final assembly. In addition, the erected silo, which serves as a crane structure for raising and elevating the elevator, stays mounted, via hinge plate mounting brackets, to the trailer structure. Removal of the mounting connection of the hinge plate mounting brackets from the erected silo is the last step of the installation procedure prior to the removal of the trailer from the silo and elevator assembly.
