Definition
A semi-automated or fully automated cart that runs on rails inside deep-lane racking to transport pallets to and from the rack face. Pallet shuttle systems increase storage density by eliminating the need for forklifts to drive into the rack structure. The shuttle is loaded at the rack entry, moves the pallet to the designated position, and returns for the next pallet. These systems are increasingly used in cold storage and high-volume distribution centers.

Drive-In Rack
A high-density warehouse racking system where forklifts drive directly into the rack structure to place or retrieve pallets on rails along both sides. Drive-in racks maximize storage density by eliminating aisles between rows, making them ideal for large quantities of identical products. Pallets used in drive-in racks must have precise dimensions and strong bottom decks, as the rails support the pallet by its bottom deck boards rather than its stringers.
Racking
The practice of storing loaded pallets on elevated warehouse racking systems (pallet racks). Racking places unique demands on pallet strength because the pallet spans across the rack beams with its load weight concentrated on the supported edges rather than distributed across a flat floor. A pallet's racking capacity is typically its most demanding load rating, and not all pallets are suitable for racking. Rackable pallets must be specifically designed and rated for this application.
Conveyor Compatible
A pallet design that meets the dimensional, weight, and structural requirements for reliable automated conveyor handling. Conveyor-compatible pallets must have consistent dimensions, flat bottom deck surfaces free of protruding nails, and sufficient rigidity to travel smoothly on roller or chain conveyors. Bottom board spacing and orientation are particularly critical, as gaps or misaligned boards can catch on conveyor rollers and cause jams.
Warehouse Management System
Software that controls and optimizes warehouse operations including receiving, putaway, picking, packing, and shipping of palletized goods. A WMS tracks pallet locations, manages inventory at the pallet level, and directs material handling equipment. Pallet standards (dimensions, labeling, barcode/RFID) must align with WMS requirements for accurate tracking. Modern WMS platforms integrate with automated handling systems, conveyor sortation, and transportation management systems.
