ABSTRACT:
A multi-shelf storage rack having spaced shelf-supporting uprights arranged in pairs, each pair has a front and a rear upright, the uprights having two rows of vertical notches extending vertically thereof in which the shelves are supported. The shelves have a pair of transverse rails extending from the front to back with a stop at the back. A wheeled dolly is positioned on these rails and the dolly has a spring-biased latch pin that restrains it against movement on the rails. An outrigger, can be hung on the uprights in position in front of a selected shelf, secured against accidental removal whereupon a latch pin-releasing device on the outrigger may be operated to release the latch pin on the dolly and the forward end of the dolly rolled from the rails on the shelf onto matching rails on the outrigger to a position where the dolly is exposed vertically for loading or unloading by a crane or hoist. When loading or unloading is completed, the dolly is rolled back onto the shelf and an inclined ramp on the outrigger retracts the latch pin on the dolly until the dolly is back on the shelf when the latch pin will spring into latching position. The outrigger is thereafter lifted off the rack by the crane or hoist and placed on the floor or hung in front of another shelf.
