Components Of A Multi-Tier Racking System
Now that you know about how awesome multi-tier racking systems are, what exactly are they made of? Let’s take a closer look at the building blocks of these space-saving wonders and see how they come together to create a super-efficient storage solution.
Upright Frames
Upright frames are the vertical pillars that support the multi-tier pallet racking system. They provide structural support for the whole building, sustaining the weight of stored products, shelves, and platforms. These frameworks are normally constructed of high-strength steel and are firmly secured to the floor for stability.
The design of upright frames varies according to the kind of multi-tier racking system. Some systems use open-back frames, while others use closed-back frames to increase stiffness. The height of these uprights is adjustable to fit varying ceiling heights and storage needs.
Beams
Unlike the vertical essence of upright frames, beams are horizontal components that connect those posts and form the levels, or tiers, of the racking system. They’re responsible for supporting the shelves or pallets on which items are housed.
Beams are available in various lengths and weight capacities, thus providing more versatility in storage layouts. Additionally, their materials are also diverse, with steel beams being the most popular thanks to their strength and durability. But other alternatives, like aluminum or wood, are also applicable for smaller weights.
Decking
You’ve already got the uprights and the beams. It’s time to add decking to the equation, as without this platform, you cannot store anything. When it comes to decking, the most common topic to talk about is its material, which is a huge collection of choices ranging from wood and wire mesh to steel.
Decking can also be solid for high load-bearing capability or perforated for proper ventilation. The ultimate choice depends on what your priorities are. If you need to store huge amounts of product, solid decking is perfect. But if you want to ensure sprinkler water flows through in the event of a fire, consider perforated decking (or wire mesh).
Stairs And Walkways
Without stairs and walkways, it would be “mission impossible” to access higher levels in multi-tier racking systems. Like other components, these elements are also made of steel (or aluminum) and are engineered to fulfill certain safety requirements.
Specifically, walkways are raised platforms that link various parts of the racking system, while stairs allow vertical access between floors. Handrails are often employed along walks and stairwells to improve safety and prevent falls.
Safety Features
Because of the elevated working areas, multi-tier racking systems require a high level of safety to reduce the risk of accidents. To do that, the design must incorporate a number of safety elements below:
- Handrails: As mentioned above, sturdy handrails are put on both sides of walkways and stairs to protect workers from falling when reaching various levels within the multi-tier pallet racking system.
- Kickplates: These are metal plates affixed to the front edges of platforms at all levels. Kickplates prevent products from accidentally rolling or tumbling down the platform’s edge, therefore safeguarding workers and other goods below
- Safety gates: Their main role is to limit access to certain locations or levels of the racking system. These gates can be controlled manually or electronically, ensuring that only authorized workers have access to certain regions, such as locations with heavy traffic or where dangerous goods are housed.
- Load notices: Load notifications should be clearly visible at all levels of the racking system. They identify the level’s maximum weight capacity, which prevents overload and structural collapse. To ensure the racking system operates safely, load notifications must be reviewed and updated regularly.
- Anti-collapse mesh: You can place anti-collapse mesh on the rear of the upright frames to prevent objects from falling through the racking framework. This is particularly crucial in warehouses where small items or loose materials may fall from higher floors, posing a safety threat.
- Safety barriers: Also known as bollards, these protective barriers are often built around the perimeter of multi-tier racking systems to protect them from forklift collisions. These barriers absorb the force of inadvertent accidents, reducing damage to both the racking system and the stored items.
Choosing The Right Multi-Tier Racking System
Selecting the best multi-tier racking system for your warehouse requires a thorough examination of several criteria. This section will walk you through the top 6 factors you should keep in mind during the decision-making process.
