Pallet Flow - Dynamic Storage Fed by Gravity

The UNARCO Pallet Flow Rack system is driven by gravity. Unlike static systems, such as Drive-In racking, product flows back to a picking position and is easily accessible to the operator. It is perfect for fast-moving product with first-in/first out (FIFO) stock rotation. Heavy-duty skate wheels on sloped shelves allow palletized loads to flow forward for picking. The high-density storage utilizes warehouse space with fewer aisles.

How does the Pallet Flow Rack work?  Full pallets are placed on the back end of the pallet rack with pallet flow lanes installed.  Each lane has wheels or rollers that automatically send pallets forward to the picking position on a sloped shelf.  The pitch can be changed to provide a gentile flow that will not damage product.  UNARCO engineers can calculate the proper slope and test at our in-house facilities with your actual product.

Smooth rolling metal skate wheels on sturdy rails come pre-assembled.  Simply drop pallet flow lanes into the bays and secure with a Tek screw.  Pallets arrive at the pick-face on the aisle and come to rest with a metal stop which keeps each pallet aligned for picking.

More complex systems such as Pick Modules can flow pallets automatically to a carton flow system so pallets can be broken down for split-case picking.

A durable metal finish and pre-galvanized side channels ensure your pallet flow system will last through all of the daily abuse and constant strain of warehouse activity. Pallet rack and pallet flow lanes arrive together with UNARCO because no one has a wider assortment of gravity flow options.

For steel containers or plastic pallets UNARCO manufactures full-width, wide roller pallet flow with rollers up to 54" wide.

Pallet Flow in-line, staggered wheels & Full-Width Rollers

Skate wheels are assembled on 2″, 3″, or 4″ centers and staggered wheels are available for heavier loads on 1-1/2″ or 2″ centers. It is easy to create pallet flow lanes by simply dropping each track into the bay. Side rails fit securely in the step of the beam and a metal stop at the end keeps the pallet in the bay.

It is easy to load pallets from one side of the pallet racking and pull them from the other. Pallet loads from behind move forward automatically into the picking position. As a result, this system is ideal for rotating perishables or date-sensitive inventory.

There is no limit to the size of a project or storage density. Deep Lane Pallet Flow stores as many as twenty pallets deep with the use of electro-mechanical or pneumatic speed-braking systems. UNARCO engineers braking systems throughout the lanes to control pallet flow speed.

System Highlights:

Pallet Flow Systems take a static rack and add dynamic flow rails for high-density shelving with automatic gravity fed flow.

  • Reduced handling costs because product rotation is automatic

  • Powered by gravity with no electricity needed

  • Dedicated aisles for loading and unloading create efficient work flow

  • Storage density is doubled within the same square footage

  • Higher density means less real-estate and less utility costs

Less forklift handling means less product damage.  Pallet flow systems from UNARCO offer flexibility to flow any pallet type because of product depth.  No other pallet rack company manufactures metal wheels, plastic wheels, and wide and full-width roller systems for pallet flow.
