Patent 8960455 was granted and assigned to Spacesaver Corporation on February, 2015 by the United States Patent and Trademark Office.
A mobile industrial rack system which includes a flue spacer, a carriage spacer, and a synchronous motor control that individually and collectively allows the rack system to be used on unleveled surfaces. The industrial rack system is therefore well suited for storage facilities in which it is not possible or not desired to level an otherwise unleveled floor.
