Cantilever racking stands as the ideal choice for storing lengthy, hefty, or unusually shaped loads. This system optimizes all dimensions of available storage space, enabling the storage of large, bulky, and irregularly shaped items without any structural barriers obstructing access to the shelving. On the other hand, floor stacking is an alternative, but it consumes a significant amount of space within your warehouse or outdoor storage area. Its stacking height is limited, resulting in cluttered storage areas that fail to capitalize on the vertical space within your warehouse or facility. So, when is the right time for cantilever racks?

Inventory Protection

Elevating products above the floor or ground is essential for safeguarding them from potential damage, adverse weather conditions, and other external factors. Utilizing appropriately designed cantilever racking or incorporating compatible accessories for such racking ensures both the security of your products and facilitates efficient counting, inventory management, and order picking processes.

Material Handling Accessibility

Although pallets are not well-suited for cantilever racking, the items stored within are frequently handled using forklifts and various other material handling machinery. By opting for this method, instead of retrieving loads from ground level, forklift operators can conveniently access materials from a shelf, streamlining their workflow and enhancing efficiency. This approach not only contributes to a safer working environment but also addresses the paramount concerns of warehouse managers: safety and increased productivity.

Ease of Use

The installation and reconfiguration of cantilever racking are straightforward processes. Since traditional shelves are not present, making adjustments to the height and angle of the arms is a swift and uncomplicated task. This inherent flexibility in the shelving design enables you to accommodate a diverse range of loads. Such a configuration significantly minimizes the time required for handling long loads, ultimately boosting the productivity of your warehouse staff by enhancing stock accessibility. Moreover, you have the option to acquire additional arms of varying lengths, expanding storage possibilities and accommodating loads of all sizes and shapes.

Space Optimization

Rather than dealing with multiple sprawling piles of materials or goods aligned in a single dimension, cantilever racking offers the capability to neatly stack elongated loads such as timber, trusses, pipes, or plywood. The crucial factor lies in meticulous pre-installation design. Although altering the height and arms of the racking is a straightforward task, moving the beams and bases can be somewhat more challenging. It’s imperative to incorporate spacious operating aisles to accommodate forklifts, pallet jacks, and other material handling equipment.

Cantilever racking can be configured in various arrangements, most commonly positioned against a wall for single-sided racking, or placed back-to-back for double-sided racking. The spacing between the uprights can be adjusted to fit snugly into corners, angles, or any available nook in your warehouse, effectively optimizing all available storage space.

What is Cantilever Beam Deflection?

Cantilever beam deflection refers to the gradual downward bending observed in cantilever arms when subjected to heavy loads. While some degree of deflection is typically expected in cantilever arms, excessive deflection poses a potential risk to the integrity and stability of the supporting rack system.

Before we delve into the topic, let’s clarify the concept of “cantilever beam deflection.” In traditional pallet racking, you’ll find upright frames and horizontal “beams” connecting these frames. In contrast, cantilever racking features arms that extend outward from the system instead of conventional beams.

Although they are officially called arms, many people refer to cantilever arms as beams since they perform the same function – supporting the load.

When Does Cantilever Beam Deflection Occur?

Cantilever arms experience deflection when subjected to loads that exceed their rated capacity. Additionally, incorrect loading practices can lead to arm deflection or other forms of damage. These loading errors encompass point loads and overloading.

Point loads, sometimes referred to as tip loads or end loads, are positioned at the outer end of the cantilever arm rather than being centered or located close to the upright support. Point loading leads to an undesirable concentration of stress on cantilever arms and can potentially result in deflection, causing the ends of the arms to bend downward.

Overloading occurs when a cantilever arm is burdened with a weight exceeding its intended capacity. Certain arms are designed with higher storage capacities to accommodate heavier loads. In contrast, arms with lower capacity should be loaded with the appropriate amount of product to prevent overloading and the associated deflection.

Tips to Avoid Cantilever Beam Deflection:

Here are some tips to help you minimize cantilever beam deflection:

Brace Set Length

To achieve uniform weight distribution across cantilever arms, it’s imperative that they bear equal loads. The spacing of cantilever beams plays a pivotal role in ensuring this equilibrium. The length of cantilever brace sets is the key determinant of arm spacing, making the selection of the appropriate brace set length crucial in preventing deflection in both arms and the load.

Choosing the Right Arms

• Selecting the correct cantilever arms involves considering three essential factors: arm length, arm capacity, and arm pitch.
• Arm length should match the dimensions of the load, preventing any overhang from occurring, which could lead to deflection.
• Arm capacity should not only meet but ideally exceed the weight of the items being stored, ensuring safety.
• Choose between straight and inclined arms based on the product to be stored. Inclined arms are particularly suitable for cylindrical items at risk of rolling forward.

Properly Loading the Arms

• Loading practices significantly influence the avoidance of cantilever beam deflection.
• Avoid shock loads caused by sudden dropping of the load onto the arms, which can result in arm damage and deflection. Load the items slowly to prevent these shock loads.
• Eliminate point loads by achieving uniform distributed loads (UDLs). Centering the product on the arm or positioning it as close to the upright as possible helps achieve UDLs, promoting longer arm life through even load distribution.

Leave Overhang

While overhanging loads off the ends of the arms is generally discouraged, there is a beneficial type of overhang that facilitates equal weight distribution among arms. This involves allowing overhang off the first and last arms to the left and right. This practice ensures that each arm supports an equal load, reducing strain, particularly on the first and last arms. The appropriate amount of overhang depends on the distance between arms and the rigidity of the load.

Implement Forklift Training

• Effective forklift operation plays a critical role in preventing damage to pallet racks and cantilever arms. Ensure that all certified forklift operators receive thorough training and undergo regular quality assessments. Forklifts are a primary cause of damage to both pallet racks and cantilever arms.
• Maintain a minimum 6-inch vertical lift clearance between the top of the product and the next arm to enable safe loading and unloading by forklift operators.

Allowable Deflection for Cantilever Beams

• Both pallet racking and cantilever racking systems come with an allowable deflection threshold. Some degree of deflection is typical, especially when subjected to heavy loads, as it is an inherent consequence of gravity.
• Every cantilever arm is constructed with a minimum 2-degree pitch, primarily designed to counteract deflection. When the arm is fully loaded, it should never bend lower than parallel to the floor.
• It’s crucial to have a clear understanding of your storage system’s limitations by calculating the permissible deflection.

How to Calculate Cantilever Beam Deflection

Standard pallet rack beams utilize a specific formula to determine acceptable deflection. However, when it comes to cantilever racks, applying a formula in a similar way is not feasible.

In the case of cantilever racks, the arm’s pitch serves as the indicator for potential over-deflection. When the arm is fully loaded, it should always remain at least parallel to the base, maintaining an angle of 90 degrees or greater. If the arm deviates from this position, there is a risk of the load slipping off onto the ground. If the load surface is level, a placed level should never indicate anything less than plumb.
