How to choose pallet racking

When you choose to use industrial pallet racking you have to know exactly what you looking for. There are a few questions you need to answer. How many items do you have for storage or how many items will you potentially store? What type of things will you be storing? How much money are you willing to spend on industrial racking?
Pallets racking is a material handling storage aid system designed to store materials on pallets. Although there are many varieties of pallet racking, all types allow for the storage of palletized materials in horizontal rows with multiple levels.
Drive-in and Drive-through (sometimes spelled Drive-thru) are storage rack configurations that allow the forklift to drive directly into the lane of stacked rows (called a bay). The difference between a drive-in and a drive-thru pallet rack system is simply whether the bays have an entry at only one end, or at both ends. Drive-in pallet rack systems use a common entry and exit, while drive-thru systems have entry points at either end of the bay. Because a drive-in racking system has only one entrance, it uses what is called a LIFO (last in, first out) storage method. With only one entrance, the last pallet put into a row is necessarily the first one to be taken out. A drive-thru storage system, with two different entry points, can also use a FIFO (first in, first out) storage method. With a FIFO system, pallets are loaded in one end and are pushed back to the other end, where they are then at the front of the row on the opposite side. The first pallet put into such a row is the first one taken out at the other end. This system is advantageous for material with an expiration date or wherever shelf life is a major concern.

Structure of pallet racks

A push back pallet racks for loading and unloading pallets characterized by at least one loading and unloading mechanism that includes a matching set of units. The general structure of a inclined pallet racks is known to those skilled in the art and will not be discussed here. Instead, this disclosure will concentrate on the novel structure of the carrier rails, the supporting channel and the integral track mechanism which are the elements of a pallet racks to which this invention is directed.
Some embodiments of the pallets racking are relatively easy to assemble and disassemble. The pallets racking may also be modular to facilitate expansion of the pallet mole to support additional plants. An adjustable pallets racking system has a column with a plurality of teardrop shaped slots and a beam having a connecting bracket that connects the beam to the column. An adjustable pallets racking system has a column with a plurality of teardrop shaped slots and a beam having a connecting bracket that connects the beam to the column.
A safety system for a pallet racking having a plurality of upright posts supporting horizontally disposed load beams comprising: at least two extension means for extending the effective vertical extent of a post. Pallet racking systems have for a number of years provided a primary storage support structure in large warehousing storage and distribution facilities. In highly efficient modernized warehousing operations, forklifts or other vehicles are commonly employed to load and remove loaded pallets from pallet racks.
