Abstract: A multi-load position push-in flow rack capable of moving and storing loads in tandem comprises front and rear uprights mounting a pair of horizontally spaced inclined rails on which load transfer apparatus is mounted. The load transfer apparatus comprises an elongated carriage supported for reciprocation on the rails by a lower series of wheels and a shorter load support mounted for reciprocation relative to the carriage by an upper series of wheels which are located on the carriage and which engage the undersides of the load support. Abutments are provided at the rear end of the carriage for coupling the load support to the carriage so that they can move together when loaded. Stops are provided at the front and rear ends of the rack to limit the travel of the carriage therein. In the course of loading, the load support with a first load thereon is pushed rearwardly relative to the carriage to expose the front of the carriage for accepting a second load and to couple the load support to the carriage.

Abstract: A storage rack having columns with apertures releasably mounting load support brackets is provided with clean-outs at the base of each column to enable foreign matter which enters the columns to be removed from the insides of the columns. Each column has a front flange and side flanges with bottom edges which engage a base plate. The front flange has a lower edge defining an upwardly-narrowing recess at the base of the column. A pair of gusset plates with inturned deflector flanges extend upwardly from the base plate and along the side flanges of the column. Each gusset plate has a recess in its lower edge, and weldement in each gusset plate recess secures the side flanges and the gusset plates to the base plate.
