Pallet racking is a material handling storage system that allows easy access and monitoring of pallets. It uses space efficiently and increases storage capacity. There are several types of pallet racking systems, including selective pallet rack, narrow passage racking, double deep rack, pushback rack, drive-in rack, and pallet flow rack. Each system provides different levels of density and requires specialized equipment.

1. PALLET RACKING SYSTEM
Pallet racking:
Pallet racking is one of the type of material handling storage system .Pallet racking will allow access to
each pallet for easy removal of goods and simple storage monitoring. The pallet rack is constructed so
that it uses the storage space effectively, increases the capacity of material storage areas, and
contributes to the transparent arrangement of the material and goods to be stored. In General, the
pallet rack structure is used for storing of pallets with material directly on the rack’s beam or on its
crossbeam. Barrels, rolls of material, and bundles of sheet metal or boards are stored on the specialized
crossbeams. Smaller materials that is stored on the decking of the pallet rack’s bay. The decking can be
manufactured by the material chipboard in various thicknesses, steel grating, panels, etc. The racking
quote is made to the customer using their requirements. It is very common to have single row pallet
racking around the perimeter of the warehouse and double row racking in the middle. The passage
width between the racks is determined by the type of forklift we are using in the warehouse or storages.
There are different types of racking system based on the place of the industry and the type of the
industry and the requirement of the client. Below we can discuss about the different types of ranking
systems clearly.
Selective Pallet Rack
This is one of the most common styles of rack system. The cost of this racking system is low, readily
available and provides access to every pallet. The down side is that nearly 50% of the facility is dedicated
to passage space.
Narrow passage racking system
Narrow passage rack is a variant of selective rack where the passage is narrowed, typically to 60". The
passages are accessed by a turret truck. The investment in this racking system is similar to selective rack,
the specialized lift trucks are typically more expensive an operational efficiency is reduced because only
a single vehicle can access the passage at a time limiting the number of vehicles that can work in the
facility at time. Narrow passage racking system can increase warehouse capacity by as much you can
you want in your space

2. Double Deep Rack system
Double deep racking system is another variant of selective rack where two racks are stood back to back
and the rear pallet is accessed by a specialized lift truck that extends into the back of the rack. Double
Deep Racking system can increase warehouse capacity by as much as based on selective racking
passage. Pallets should be stored in pairs with the same product in both the front and back position of
the rack. Double deep rack provides a nice increase in density when compared with selective, but
requires special equipment and is slower to operate as compare to other racking system.
Pushback Rack system
A pushback rack system can provide from 2-6 deep storages, significantly increasing the density.
Wooden Pallets are placed on carts located on a sloped rail system and pushed back by the lift truck
operator. When removed, gravity brings the wooden pallets back to the aisle.
Drive In
Drive in one of the rack system of another high density storage option in which the lift truck drives
inside the storage rack and places the pallets on load rails. Drive in rack systems can range from 2 all the
way up to 20 pallets deep. The systems are relatively inexpensive, but are limited due to lack of
selectivity, low productivity and intended to damage.
Two Wide Drive in

3. Two wide drive in rack system is a variant of drive in where lift trucks handle two pallets side by side at
a time and place them concurrently on the load rails. This is used for limited applications on high volume
applications.
Pallet Flow
In a pallet flow system the wooden pallet is placed in the rear of the system on a series of rollers; it is
typically with a centrifugal braking system. The wooden pallets roll forward by gravity to the front of the
system providing FIFO storage. Pallet flow systems can provide very high density. They are typically the
most expensive option, require good quality pallets and require more maintenance for this pallet flow
racking system.
