Abstract:
A palletless rack-type parking system with a stacker crane, comprising:a plurality of multistory racks each having a plurality of parking spaces in a lattice form and arranged on a support surface to be spaced apart from each another at a regular interval to form vertical spaces between them; a plurality of storage fork bars each including a first projection tab projected from a predetermined portion of a lower surface thereof to have a predetermined height and horizontally mounted on an upper surface of a first support beam in a regular interval through the first projection tap to cross the support beam in a right angle, at least one end of which is projected longer from the support beam of the rack in a cantilever beam form; a transporting fork including a plurality of transporting fork bars with a second projection tap projected from a predetermined portion of a lower surface thereof to have a predetermined height, in which the transporting fork bar is not higher than that of the storage fork bar, and arranged in a regular interval in parallel to each another to be alternately positioned between the storage fork bars and a second support beam arranged to cross the storage fork bar in a right angle and for supporting the second projecting tap facing its lower surface; and a stacker crane installed in each vertical space between two neighboring racks and operable in more than two-axial directions of leftward, rightward, upward and downward with the transporting fork being mounted thereon, in which the transporting fork laterally approaches the storage fork bars and the transporting fork bars enter into, moves up and down and retreats from the storage fork with being alternately overlapped between the storage fork bars.
