When comparing different methods of storing and accessing pallet loads on rack, the choices can be a little mind boggling. Do I go with Push-Back Rack using gravity feed to deliver loads to the front edge? What about the loss of vertical space? What if something gets hung up? How about Drive-In Rack? Do I trust my forklift drivers to maneuver carefully enough? What would a rack collapse cost me? Does horizontal flow rail work for me? Can I deliver goods fast enough?

How can I know which rack style to choose?

So many features to choose from and factors to consider as you look at how to most effectively move pallets into and out of storage and what kind of storage best serves the volume you must move.

In the table below, you’ll find listed major factors and features that best serve moving pallets in and out of storage. It should help make your choice easier when you must decide on a rack style for your facility.
