The first thing to consider is the load (pallet and what’s on the pallet) and its dimensions. That load dimension starts with the length of the pallet. They are one of the most popular styles available, largely because their unique design requires no bolts, nuts, clips, or other accessories in the assembly process. Since most pallets are 48” deep, then taking away 6” would equate to a frame depth of 42”. Typically, 42-inch deep uprights are used, with 3 inches of overhang in the front, and 3 inches overhang in the back. A guide to perfect pallets. This is one of the important steps when determining the rack frame depth for selective pallet rack. In the main there are two types – two way and four-way entry and they will be either 1200 x 1000mm or 1200 x 800mm. It’s much harder to go back and reconfigure a rack system after the fact, so taking overhang, driver skills, traffic patterns, and throughput into account is critical on the front end. Racking systems should be properly designed and installed, this includes being able to safely take the load of the goods being stored. In this case you would pick which ever dimension is greater, either the length of the wooden pallet or the length of the load. When we talk about pallet racking hazards, most people immediately imagine scenarios where a system has suffered a complete or partial collapse. 1200mm pallets can sit on the beams giving a 100mm gap between each pallet and the end frames. You may already have pallet racks and want to adapt them to store longer loads. Aisle width should take pallet overhang into account on both sides of the aisle, as overhanging pallets are ubiquitous. Another point to consider when specifying pallet racking is whether the pallets, will need any additional support on the racking beams in order to support pallets that are in poor condition or overloaded. Stack in columns. Pallet stops are also commonly referred to as backstops, pallet stops, pallet load stops or flue space protectors See the diagram below. When establishing the clearances within a racking system the first consideration is the type of pallet or stillage to be stored. Pallet racks require evenly distributed loads. Frame Depths and Pallets Sizes. Clearance between rows of racks should consider rear pallet overhang, possible building columns and at least 6″ clearance when intermediate sprinklers are to be installed in racks. Pallet racks are unbelievably useful, but they can also present some serious safety hazards for your workers when used improperly. If bent bars or damaged vertical posts are discovered, the affected section should be taken out of use until it can be properly repaired. Height-To-Depth Ratio: If the ratio of the rack height to the top of the uppermost load to the frame depth exceeds 6 to 1, additional stabilizing is required. Determine System Capacity. Anti collision system for racking. Beam height can be easily adjusted, and beams can be added in to provide extra support, or removed to allow for easier access. Pallet racks should be inspected upon installation and periodically checked for damage. They are typically attached on the rear of bay, thus preventing pallet overhang and potential safety risks. Teardrop Pallet Racking When possible, teardrop pallet racking systems are the way to go. 80% of pallets in use are 48″ long.

Wire Decking and other accessories are available to better control variations in the pallet size. Getting it right helps avoid additional costs. standard Chep pallets and the product you are storing on these pallets does not overhang the pallet then 2600 wide beams would suffice. Rack Decking Load Guide : Rack loads aren’t just simple weight vs. structure. back to back clearances and the pallet overhang. Pallets should overhang 3” from the front and 3” from the back of each level to guarantee that the weight is distributed evenly. To easily get a proper fit, subtract six from the depth of your pallets. If you are able to provide us with all of the measurements on our handy diagram, we can get straight to work on designing your pallet racking system to SEMA standards. How these pallets are placed within the rack will establish the first set of clearances ie. Improper alignment The next step is to determine the frame capacity of your pallet rack. Loading figures refer to a uniformly distributed load (UDL). The next crucial factor is the weight of the pallets as this will affect the type of beam to be used. back to back clearances and the pallet overhang. Rather than a forklift directly positioning the pallet onto the rails (as is the case in drive in racks); the pallet is placed onto a motorised shuttle at the mouth of the lane, carried along up the rail and placed down in the optimum position on the rack with minimal distance between pallets.

For the height, you’ll need to know the clear height of the building and how much below that height you want the top of the top pallet. How to Secure Warehouse Pallet Racking. Here is an equation to calculate the minimum aisle width when using these forklifts: Head Length + Load Length + 12” for Maneuverability + 6” for Pallet Overhang = Minimum Aisle Width For example if the pallet (x dimension) is 1,000mm deep the frame (y dimension) needs to be 900mm deep providing an overhang on the front and rear beams of 50mm. Most racking systems are laid out with wider aisles to accommodate these machines. Adjustable Pallet Racking. Fitting the anti-collapse mesh to a pallet rack is simply a matter of securing metal brackets that stick out from behind the racking at an angle of 45 degrees to the uprights. Parts used in repairs should be provided by the manufacturer or should meet with the manufacturer’s specifications to ensure employee safety. In the situation that your pallet is longer than your pallet rack depth, you must determine what is safe. Pallet Rack Styles.

The recommended pallet overhang is 3”, but this can cause a problem with 4- way pallets if you are not using wire decks. When establishing the clearances within a racking system the first consideration is the type of pallet or stillage to be stored. How tall is the load? In the main there are two types - two way and four-way entry and they will be either 1200 x 1000mm or 1200 x 800mm. There needs to be space between them to allow for water displacement when using ESFR sprinklers. With Sperrin Metal Storage Solutions Adjustable pallet racking system, you can modify beams to suit changing requirements. As skilled storage experts, Warehouse Storage Solutions can help you ensure this is done correctly. TC3-5 pallets can be accessed by fork lift from all four sides. Standard Pallet Rack Frames are available from 24” to 48” deep and are stocked in sizes from 8’ to 24’ high. This ensures that overhanging products will not become a safety hazard. Pallet Condition and Overhang. The dimensions, shape and size/density of the load also factor in. If the pallet is 1,200mm deep the frame needs to be 1,000mm deep providing an overhang front and rear beams again of 50mm. You know what that means: simple and fast assembly! This will allow a 3-inch overhang on both sides. 1. The general specification for pallet racking is the width of the bays, the standard bays being 2.7m wide, therefore 2 No. Columns ensure maximum stacking strength. Equally, any goods hanging over the edge of the pallet are in the wrong place. While pyramid stacking may seem logical, it reduces the overall stability of the load and risks damaging the boxes on top. Sometimes the product placed on the pallet overhangs the wooden pallet structure. When using pallet ‘pump’ trucks, care should be taken that the truck wheels are not resting on the pallet runners when lifting as this can damage the runners. Protect racking if it is likely to be struck by lift trucks and other vehicles. Why do you want overhang? Unit loads on upper levels containing boxes, cartons, and other loose loads should be effectively prevented from falling by wrapping, strapping, or by some other means. And if your goods overhang the side of your pallet more space will be needed within the design for each pallet. As our charges are based on a combination of weight and volume, anything that takes extra space or makes your pallet non-stackable could incur surcharges.

How these pallets are placed within the rack will establish the first set of clearances ie. Counterbalanced Forklifts in Wide Aisles (WA) The majority of forklifts are 3-wheel or 4-wheel counterbalanced forklifts. The main objective of a pallet stop is to prevent pallets from hanging off the back of the racking.
