Abstract: An improved automated material handling system that allows an overhead hoist supported by a suspended track to access Work-In-Process (WIP) parts from storage locations beside the track. The automated material handling system includes an overhead hoist transport vehicle for transporting an overhead hoist on a suspended track, and one or more storage bins for storing WIP parts located beside the track. Each storage bin is either a movable shelf or a fixed shelf. To access a WIP part from a selected shelf, the overhead hoist transport vehicle moves along the suspended track to a position at the side of the shelf. Next, the movable shelf moves to a position underneath the overhead hoist. Alternatively, overhead hoist moves to a position above the fixed shelf. The overhead hoist is then operated to pick a desired WIP part directly from the shelf, or to place one or more WIP parts directly to the shelf.
