Different Types of Pallet Racks

Pallet rack is a system of storage aid designed to store items on the pallets also known as skids. The pallets store the materials in a horizontal row over multiple levels. The Forklift trucks which are known to be integral part of the pallet racking system place the loaded pallets on the racks to store. These racks are essential part of any warehouse, distribution facilities, retail centres and the manufacturing facilities.

Different types of pallets are available in the market. But all work on the concept of increasing the density of the storage and decreasing the storage costs. Different designs cater different business needs. Each design functions differently with its own advantages. Few things need to be taken into consideration before buying any type of pallet rack storage system. These considerations include, what is the desired density of storage required, what is the floor space and the height of the building where the pallet will be placed, how the doors and the columns of the building are placed, accessibility to the inventory and the rotation of the inventory, weight and size of each load that will be stored, what kind of storage design is optimal and the cost that will be incurred for the materials and its installation.

Although the high density pallet rack storage system has many benefits, there are few disadvantages as well. And they include, limited access to all the stock at one time, and the expenses incurred to maintain such systems. Some pallet storage systems are least expensive when compared to the high density pallet storage system. But when the facilities where these systems will be utilized are medium or large, the use of high density pallets becomes essential because they are efficient, time saving and optimizes the space to the maximum extent.

The most common types of pallet storage systems used in the most of the facilities are, the drive in and drive through system, push back pallet rack system, compact mobilized pallet racks system and the pallet flow system.

The drives in drive through rack system works on letting the forklift truck directly enter the lanes to lift or place the materials on the rows. The drive in rack system has only one opening which is used for both entrance and exit thus it follows the LIFO, the last in first out storage method. The Drive through rack system has opening at the both ends, one for entrance and another for the exit. This system works on the FIFO, first in first out method.

The Push back pallet rack system works on the principle of organizing the space in the facility by depth rather than by the width. It works on the LIFO, last in first out storage system. In this system each bay is up to six pallets deep and the pallets are stored on the carts to fit perfectly on the rails.

The pallet flow systems use the depth to increase the capacity of the storage system. It works on either LIFO or the FIFO systems. This system is also known as the density flow or the gravity flow systems.

Compact mobilized pallet storage systems are used to maximize the storage space in the warehouses. It is also known as the motorized mobile rack system or the mobile industrial rack system. These racks double the storage space in the facility.

Used Pallet Racks

Pallet racking is the system where the materials are stored on the pallets. This storage racking system is used in warehouses and many other industries like the manufacturing, distribution, wholesale and retail centres. Pallet racks are very useful because they improve the storage density and are very efficient and durable. But they are also very expensive. So many business owners prefer to buy the used pallet racks for their facilities. Because they are used, they come for cheap and most of them are available in the good conditions. Many supply centres buy the used pallet racks from many businesses and sell them to the others who require them.

Pallet racks come in many different colours, shapes and sizes. Each variety has its own functions and advantages. The business owners have to choose the right type that suits their requirements. The most popular types used pallet racks that are bought widely by many business owners are, tear drop, platier, prest slide and lock, republic, sturdi bilt, speedrack, structural, unarco, T bolt, penco, redi rack, wire way, frick gallagher, and webb style. Of all these preferred styles, the teardrop is the most sought after used pallet racks.

Pallet rack means the metal structure and the frames that hold the materials in the facilities. Because they are used to hold heavy loads, the buyer must carefully look for any wear and tear on the frames to the structure before buying the used racks. Any damage to the frame can cause the load to fall down and can cause huge accidents and loss to the materials and the workers around the pallet. Apart from this, any repaired area on the pallets frame will be hidden by paint.

Such frames will not be safe for reuse because there is no evidence that this frame was repaired by a qualified technician. So there is no guarantee that it will bear the weight of the new loads. And also the frames can be damaged by rust if they are kept in a climate controlled facility. A thorough inspection must be carried out before buying a used rack.

Before selecting a pallet rack for the facility, every business owner needs to consider few things. What are the materials that need to stored and what is their size and weight. What is the height of the ceiling in the building and the floor space, what equipment will be used to lift the pallets and what amount of storage density is required.

Pallet Rack

Pallet rack is one of the most important equipments required in every warehouse. It holds stacks of goods and materials for storage. It has multiple levels of shelves to store goods and is often made of steel beams and upright bolts. The goods stored on the rack are on display which makes it easy for the workers to reach for them without any obstacles. Pallet rack makes it easy for the pallet jack or the forklift truck to lift and carry the pallets. The rack comes in various different styles, sizes and configuration. The business owners choose the style as per their requirements. The racks are very easy to assemble and require no tools.

The different styles of the pallet rack include the interchangeable style that suits all the major business needs. The teardrop style which is the standard style in the industry. T-bolt style which is very easy to install and its shelves can be adjusted to accommodate larger sized goods.

Upright frames

The upright frames expand the storage density in a warehouse. It comes with the teardrop style holes. This rack comes with simple instructions that make it easy to install and it is the most popular choice of storage in major businesses, warehouses and industries.

Step beams

This versatile system is used in many major industries for its unparalleled adjustability. Step beams when manufactured as per the industry standards give great strength to the racks to hold heavy loads. Beams are very easy to install and can be adjusted as per the needs in the warehouses.

Welded wired decks

The wired decks improve the durability, functionality and safety of the storage rack in the facility. The wire decks come in different variety of styles and shapes that fit all types of the storage racks.

Accessories

The look and the functionality of the storage rack can be enhanced by adding few accessories like rack column protectors, flanged and fully galvanized cross bars, wall spacers and the row spacers.

Column Protector Shield

The post and the column protector shield extend the life and the durability of the storage rack. It protects the rack from any accidental collisions from the forklift trucks and other damages that occur in the process of loading and unloading. The end of aisle guards prevents any fatal injuries or accidents to the workers around the pallets.
Whether the pallet rack bought is a new one or a used one, it should be according to the safety standards set by the RMI and ANSI.

Used Pallet Racking

Pallet racking is a storage system that improves the storage density in the warehouse, manufacturing and distribution centres and wholesale and retails centres as well as in the cold storages. Pallet racking system comes in many different types that function differently as per their configuration. The common types of the pallet racking systems are the drive in drive through pallet racking, selective pallet racking, pallet flow racking systems, push back pallet racking systems and the compact mobilized pallet racking systems. Pallet racking means the entire storage system and pallet racks are part of the pallet racking system.

Buying a used pallet racking storage system cuts the costs to a larger extent because a brand new pallet racking will be very expensive. All the essential elements of the racking system must be in sound condition without any damages and no part should be missing. It should look sturdy and durable and all the bolts must fit properly. The main advantages of the used pallet racking storage system include, the space in the facility is used to the maximum benefit, all the pallets can be accessed at all the times, the system can be easily installed and configured and is very efficient in the operations. Other advantage of buying a used pallet racking is the environment is not hurt in making a new piece to meet the demand.

Whether the pallet racking used in the facility is used or a brand new one, few safety measures should be followed by all the business owners. Any loose components in the racking system will make the pallets fall apart causing damage to the frame and structure of the pallets and the faulty pallets can cause accidents in the facility. Any such damage should be immediately attended and repaired to avoid any big accidents to the people working around the pallet racks in the facility.

When buying the used ones, always buy the pallets that are not damaged earlier because faulty racking system cannot be durable and will give away when used extensively causing loading and unloading problems. They can also jam the flow systems thus blocking the other pallets in the row.

The equipment used to lift or place the pallets in the racking system should be properly motorized. And the ends of the aisles should never be blocked with pallets or any other materials. If the aisles are blocked, it leads to many fatal accidents. The pallets racking system should never be loaded above the specified limit. And the racking system should be inspected by a RMI certified inspector to check for safety measures and standards.

Safety Considerations

A material that is designed to handle storage aids and store materials on the pallets is called a Pallets rack. There are different types of pallet racks available all of which work on storing the materials in horizontal rows in multiple levels. Forklift trucks which are usually considered to be an important part of the pallet rack system place the pallets which are loaded with the materials on the racks. Pallet racks became an important part of any warehouses that have modern equipments, retail centres, manufacturing facilities and many distribution facilities since the Second World War. All the types of pallet storage system increase the storage density. The least density creator will be the least expensive and the large density providers will the most expensive pallet storage system.

Some safety considerations have to be taken care of when dealing with pallets storage system. If there is any damage to the pallets like the damage of the frame, such damage should be immediately repaired otherwise, it will cause the materials that the pallets are holding to fall. The owner of the facility should warn all the people around the racks and place a warning sign around the danger area about the damage and ensure the safety of all the workers in the racks. Pallets should be regularly inspected for the quality and any possible damages like a broken plank, missing blocks, protruding nails etc. if these things are ignored or not noticed, it will cause accidents and problems like jamming the flow system of the rack.

A proper motorized machine should be used to operate the things in the facility. The end of the aisles should never be blocked by placing the pallets or any other things that can cause fatal injuries. The racking system should never be over loaded above the recommended specifications of the load. If the pallets are overloaded, it will cause breakdown of the entire storage system. To ensure the safety operation of the storage system, regular inspection should be encouraged by a qualified inspector who is familiar with the RMI safety standards.

Before purchasing a pallet rack storage system, certain basic factors have to be taken into consideration. The storage density that is required for the facility, space of the floor and the height of the building where this storage system will be placed, the way the doors and the columns of the building are placed, the inventory accessibility and the inventory rotation of the load, the desired design of the storage system and the cost of the materials and the installation that will be incurred.

The most common types of the pallet rack storage system used in the warehouses are the drive in drive through system where both the LIFO, last in first out storage system and FIFO first in first out systems are used. The push back pallet system where the space is organized by the depth which works on the LIFO storage system. Pallet flow system also known as the dynamic flow or the gravity flow system works on both FIFO and the LIFO system and the compact mobilized pallet system that maximizes the storage space in any warehouse.

The pallet rack storage system has its own disadvantages like the high density storage system being the most expensive compared to the least density storage systems and it also gives limited access to the stocks stored on the pallets at any given time.
