US 4,549,841 A · Container storage shed installation

Abstract

A shed for storing containers in a three-dimensional system essentially including rails laid on the floor, a crane movably supported on the rails, an elevating member on the crane for vertical elevatory movement, a spreader frame mounted on the elevating member for movement in a horizontal direction, brackets on the spreader frame capable of moving vertically, twist lock pins each twistably attached to one of the brackets, three-dimensional shelves arranged on the floor along the rails, and guides located horizontally on each of the shelves. The spreader frame is thrust from the elevating member toward one of the shelves, and the brackets are moved downwardly on to a container on the shelf while supporting the spreader frame by guides mounted on the shelf, to bring the twist lock pins into engagement with the container. Then the brackets are moved upwardly to lift the container from the shelf and the spreader frame is returned to the elevating member to thereby remove the container from the shelf by the crane. A container can be placed on one of the shelves by the crane by reversing the process described above.
