Why would someone need a shuttle system?
A warehouse would need a shuttle system in the case that some of their other rack systems cannot provide a good solution. In other words, the pallets don’t work well with pallet flow or push back. Or, the customer wants to achieve deeper lanes of storage than those other systems can provide. It also has the advantage of not having forklifts drive into the racking which will prevent rack and product damage in the long run.
Another huge advantage of a pallet runner is the need for less human labor than the other systems such as pallet flow or push back. A pallet shuttle system only requires one operator to handle the mole and retrieve or unload pallets into the system. On top of that, one operator can actually control multiple pallet runners at once which can greatly increase a warehouse’s efficiency.
