Abstract

Rack arrangement designed for installation in, for example, a warehouse or a factory for storage of loads. A pair of stationary racks having a plurality of vertically and/or laterally partitioned storage spaces are arranged in spaced parallel relation. A movable rack or racks having a plurality of similarly partitioned storage spaces are arranged between the two stationary racks, with a working space defined between the facades of any selected pair of adjacent racks. A rail is mounted on the top of each stationary rack and supported thereon. A girder supported and guided by the pair of rails is movable along the length of the rails. A load transfer unit is supported and guided by the girder for movement within the working space. The load transfer unit includes a take-in/take-out device which is up-and-down movable within the transfer unit, able to support a load, and is retractably movable relative to a storage space for delivery of the load to and from the storage space.

Dependent claims

A rack arrangement including a pair of longitudinally extending stationary racks having a plurality of vertically and laterally partitioned storage spaces and arranged in parallel spaced apart relation, longitudinally extending movable racks having a plurality of vertically and laterally partitioned storage spaces and frontwardly and rearwardly movably disposed between the stationary racks, and a working space defined between opposite facades of any selected pair of adjacent racks, comprising:

a pair of rails mounted respectively on the tops of said stationary racks and supported thereon,
a girder supported by the rails and guided thereby for movement along the rails,
movable means supported and guided by the girder for movement in a longitudinal direction of the girder which is perpendicular to said rails, said movable means being movable into said working space, and
a take-in/take-out device which is vertically movable within the movable means and capable of supporting a load for storage into one of said storage spaces, said take-in/take-out device being adapted to extend into and retreat from a storage space located opposite to said movable means for delivery of the load to and from the storage space.
