Automated pallet storage and retrieval system

A multi-level storage structure, comprising:

• a plurality of vertical supports;
• a plurality of row rails connecting vertical posts positioned longitudinally relative to each other and configured to support at least one row cart;
• a plurality of load rails extending parallel to the plurality of row rails and configured to support at least one loaded pallet;
• a plurality of aisle rails extending perpendicular to the plurality of the row rails and configured to support at least one aisle cart;
• a carriage mounted to a flange portion of at least one of the plurality of aisle rails, the flange portion having inverted T-shape construction and the carriage being configured to move longitudinally along a length of the at least one of the plurality of aisle rails.

A multi-level storage structure, comprising:

• a plurality of vertical supports;
• a plurality of row rails connecting vertical posts positioned longitudinally relative to each other and configured to support at least one row cart;
• a plurality of load rails extending parallel to the plurality of row rails and configured to support at least one loaded pallet;
