Pallet racking is a single or multi-level storage system that is utilized to support high stacking of single items or palletized loads. Pallet rack systems are a fundamental component of any distribution, storage, or material handling operation. Pallet racks allow rapid access to stored materials.
Pallet rack shelving is designed to get pallets off the warehouse floor and into a warehouse storage system. Warehouse racks provide immediate accessibility to store or and retrieve pallets in and out of storage. Using selective pallet rack systems allows many businesses to fully utilize both warehouse floor space as well as efficiently manage worker time.
A typical pallet rack bay can hold two or three pallets per shelf level. Standard pallet weights stored weight approximately 2,000 lbs. Pallet rack is versatile and specialty rack sizes can hold as little as 500 lbs. to as much as 6,000 lbs. in some cases.
Warehouse racking that is designed to store palletized products are called pallet rack systems.
The central difference between shelving and racking is that shelving involves putting products into the system and retrieving them by hand. With pallet racking, the storage and retrieval of palletized materials is done using forklifts.
SEMA (Specialty Equipment Market Association) specifies a minimum clearance of 75 mm between the top of the load and the beam above and on each side.
7 Things to Consider When Designing a Warehouse Pallet Racking
- Pallet size and type
- Products turnover
- SKU/pallet count
- Warehouse environment (Cold storage, freezer storage, etc.)
- Type of building structure
- Product flow/accessibility requirements
- Seismic activity
Double deep pallet racking is a storage system that is designed to store pallets two deep. In this system, the pallets are stored at two depths, thus achieving higher storage density.
A warehouse racking system is a storage solution designed to maximize space by stacking materials in horizontal rows with multiple levels. These systems maximize storage space while efficiently organizing storage and retrieval of products and improving workflow.
A pallet rack is a material-handling storage rack system designed to store products and materials on pallets while maximizing storage space. Pallet racking uses horizontal shelf load beams that attach to vertical upright frames, creating a storage framework that supports pallets of products and materials. Stored products are accessed using forklifts.
Pallet shelving, or pallet racking, is where materials are stored on in a steel framework used for storing pallets of product in horizontal rows, and on multiple levels. They have become an essential form of shelving system for a wide range of industries.
The short answer? Yes, according to the Rack Manufacturers Institute (RMI) and American National Standards Institute (ANSI) MH16.
If you need to know how to calculate pallet rack load capacity or upright frame capacity, you need to first consider the estimated maximum load weight for each beam level. Then you multiply it by the number of levels in the racking section. The result is the required pallet rack upright capacity.
Take the weight and then multiply it by the number of loads you hypothetically intend to store. Then take that number and multiply it by the beam levels per bay. To use an example, if the heaviest load is 1,200 lbs. and you intend to put three on a pallet position, then the beam capacity is 3,600 lbs.
When standing upright, the unstable pallet can fall over and injure a worker. Occupational Safety and Health Administration (OSHA) clearly states, “Cargo, pallets, and other material stored in tiers shall be stacked in such a manner as to provide stability against sliding and collapse. (Standard 1917.14)”
A rack bay refers to the storage space between two upright columns in a pallet racking system. Pallet rack bays can have a wide variety of beam levels. Usually, beam levels are set 4-5 feet apart.
Between each upright frame, beams support the actual pallets within what's known as a bay. The higher the frames and further spaced the beams, the more pallet bays available; however, the average rack height is usually 20 feet or less.
The most common pallet rack beam lengths are 8', 9', 10', and 12'. Sizes and capacities are available in a wide array of sizes outside this standard parameter.
The 3 most common aisle widths are:
- Wide aisles measure between 12 and 13 feet wide
- Narrow aisles measure between 8 and 10 feet wide
- Very narrow aisles measure around 6 feet wide
The limits are determined by the free span headroom you have for ceiling height and the limits of the forklift being used to stock and store pallets on the pallet racks.
1200mm pallets can sit on the beams giving a 100mm gap between each pallet and the end frames. Depths of frames can vary but the most standard is 900mm where a 1m deep pallet will sit on the beams, leaving a 50mm overhang on either side, which is the ideal safety standard.
Walking under or around a pallet rack that does not have the proper protection devices, such as wire mesh decking, and/or safety netting, is unsafe and should be avoided.
Block stacking is a form of palletized storage that does not require any type of storage equipment and instead, loaded pallets are placed directly on the floor and built up in stacks to a maximum stable storage height.
Pushback racking (also referred to as pushback racking) is a high-density storage system that allows pallets to be stored from 2 to 6 deep.
Narrow aisle racking is a highly space-efficient pallet storage system. It enables businesses to achieve increased storage capacity within a warehouse and is the perfect choice for areas where floor space is limited while enabling efficient access to every pallet for picking, processing, or retrieval.
A rack is a framework or equipment utilized for storing inventory. Racks are a structural design and can include shelves, rails, bars, hooks, pegs, and more. Racks are one of the most-used tools within warehouses to manage inventory and maintain organization prior to picking and shipping.
The proper pallet stacking safety technique is to put the heaviest item(s) on the bottom of the pallet. Then put the heaviest pallets on the bottom of the stack. This will create a stable base with a lower center of gravity.
Roll formed selective racking starts at about $20-$25 per pallet position, while structural selective rack starts around $30-$35 per pallet position. As of late, these prices can vary wildly due to fluctuating steel prices.
Pallet racks consist of vertical steel frames which are connected by horizontal steel beams. Two frames and the beams create a bay area where pallets can be added. The number of pallets and the weight your warehouse racking can hold will depend on the height of the pallet racking frames and the spacing of the beams.
With nut, washer, and set-pin securely in place, insert the strike anchors into each hole through the upright legs of each pallet rack. Using a properly sized hammer, set the pin with several sharp and square strikes on the head of the pin until it is flush with the top of the anchor.
Although OSHA has no specific warehouse racking safety guidelines, they are covered by the general clause of the Occupational Safety Health Act that created the agency, which states simply that each employer shall provide a workplace that is free from recognized hazards.
Storage Equipment Manufacturers Association. Racking safety is the primary role of the Storage Equipment Manufacturers Association. They are committed to promoting and extending racking safety, installation, and use of storage equipment manufactured and supplied by their members.
Divide the cubic inches by 139 to determine the pallet's dimensional weight. For example, if your pallet takes up 96,000 cubic inches, divide 96,000 by 139 to get a dimensional weight of 690 lbs.
Components of a Pallet Rack System
- Baseplates. An upright frame has at least two (2) baseplates used to stabilize and anchor the pallet rack to the floor.
- Shims
- Beams
- Crossbars
- Wire Decking
8-foot long beams are by far the most common beam length and allow for the storage of two standard 48 inch x 40 inch pallets. Plan for three inches of clearance between the upright and the pallet, and four inches of clearance between pallets.
Most of these designs have elongated chassis to accommodate the heavy, rearmounted counterweight that balances the load in the mast and carriage. As a rule, sitdown counterbalanced forklifts need aisles at least 12 feet wide to handle standard 48 inch pallets.
Yes. According to the Rack Manufacturers Institute (RMI) and American National Standards Institute (ANSI) MH16. 1-2012, all pallet rack columns are required to be anchored or secured to the floor with bolts.
Pallet racks are made up of vertical steel upright frames which are connected by horizontal steel shelf beams. Two frames and the shelf beams create a bay. The number of pallets and the weight your warehouse racking can hold will depend on the height of the pallet racking frames and the spacing and capacity of the shelf beams.
There are five main components of pallet racks. Those components are uprights, beams, pallet supports or wire decking, and row spacers and anchors. Optional equipment like safety netting and column protectors are becoming mandatory in many areas.
