Cantilever racks are specifically designed to support lengthy and heavy items like pipes, steel tubes, lumber, metal or wooden sheets, furniture, elongated crates, and various other items. Their construction is straightforward, typically comprising a central column with extended cantilevered arms on one or both sides. Safety is paramount in any warehouse or industrial storage setting, including those utilizing cantilever storage systems. Due to the substantial weight and size of the stored items, it’s crucial to remain informed about safety considerations to ensure the integrity of your racks.
Inspect, Repair, and Replace
Regular inspections are crucial for cantilever racks due to the heavy loads they support and the potential for impacts from forklifts. The Rack Safety Group of MHI recommends conducting at least one inspection annually as a standard procedure. If the rack sustains a collision or any form of compromise, it should be inspected immediately. During inspections, look for signs of damage such as compromised arms, bases, or posts, as well as loose hardware or anchoring bolts. Any damaged areas should be unloaded and repaired or replaced before further use of the rack.
Ensure Proper Specification
Determining the number of columns and arms required to support a specific load depends on various factors, including weight, potential load sag, size, and more. The most effective way to ensure a safe and successful rack system is to meticulously specify it according to the intended load’s size, shape, and weight.
Increase Aisle Clearances
While you can’t eliminate operator errors entirely, you can design the rack system to minimize them. One strategy is to identify areas where operators commonly make mistakes and add tolerance accordingly. Aisle width is particularly important, as the transported loads in cantilever rack applications are often wide, increasing the risk of contact with extended cantilever arms. Providing operators with more space reduces the likelihood of collisions with these arms.
Outdoor Applications
Cantilever racks are frequently used outdoors in pipe yards, fabrication facilities, and other exposed environments. Many lumberyards store substantial amounts of timber and building materials on outdoor racks safely, provided that the racks are appropriately specified and loaded. Considerations for outdoor applications include:
- Anchoring: Racks should be anchored into stable surfaces to maintain their capacity. Typically, this means bolting racks onto concrete pads. Avoid anchoring racks into unstable surfaces like asphalt.
- Shelters: Using T-sheds or similar structures can protect racks and their contents from the elements, reducing the risk of snow and ice accumulation that can add excessive weight.
- Elements: Steel cantilever racks are susceptible to rust when exposed to environmental moisture. In corrosive environments, galvanized racks may be necessary for rust resistance.
- Winds: Strong winds can impact outdoor cantilever racks. Utilize windbreaks where feasible, and consult with a qualified engineer if wind conditions are a concern for the safety of the application.
For outdoor storage of long, heavy materials, it’s advisable to consistently consult a reputable rack company to provide an engineered design.
Be cautious of vertical impacts during loading or unloading operations
Educate your forklift operators about the risks associated with slamming into cantilevered arms while handling materials. When positioning loads, ensure that they are gently placed onto the arms in a manner that distributes weight evenly. Avoid placing loads off-center, as this can create uneven stress on individual arms. During unloading, refrain from pushing against the bottom of any arms above the shelf being cleared, which could dislodge the arms from their connectors.
Ensure the stability of your loads
Cantilever racks, designed for accommodating lengthy items, are susceptible to load sag, where items can bend between arms due to their weight. Forklifts can be equipped with specialized attachments to support loads during placement or removal. Improving the design of your rack system by adding more arms can help reduce sag, facilitating quicker and easier handling for drivers.
FAQ’s
How do I know if a cantilever rack is suitable for my storage needs?
Cantilever racks are ideal for storing lengthy and heavy items such as pipes, steel tubes, lumber, furniture, and more. If you’re unsure about the suitability of a cantilever rack for your specific storage requirements, it’s best to consult with a reputable rack company. They can provide an engineered design tailored to your needs.
How often should I inspect my cantilever rack for safety?
The Rack Safety Group of MHI recommends conducting at least one inspection annually as a standard procedure. However, if the rack sustains any collisions or compromises, it should be inspected immediately to ensure safety. Regular inspections help identify any damage or loose components that may compromise the integrity of the rack.
What should I look for during a cantilever rack inspection?
During inspections, look for signs of damage such as compromised arms, bases, or posts, as well as loose hardware or anchoring bolts. Any damaged areas should be unloaded and repaired or replaced before further use of the rack to ensure safety.
How can I minimize operator errors when using cantilever racks?
Designing the rack system to minimize operator errors is crucial. One strategy is to increase aisle clearances to reduce the risk of collisions with extended cantilever arms. Additionally, educating forklift operators about the dangers of slamming into cantilevered arms and ensuring proper loading and unloading techniques can help mitigate risks.
Are cantilever racks suitable for outdoor applications?
Cantilever racks are frequently used outdoors in environments like pipe yards and lumberyards. However, it’s important to consider factors such as anchoring, protection from elements, and resistance to rust in outdoor applications. Consulting with a reputable rack company can help ensure that outdoor cantilever racks are properly specified and loaded for safety.
How can I ensure the stability of loads on a cantilever rack?
Cantilever racks are designed to accommodate lengthy items, but they can be susceptible to load sag. To ensure stability, forklifts can be equipped with specialized attachments to support loads during placement or removal. Additionally, improving the design of the rack system by adding more arms can help reduce sag and facilitate easier handling for operators.
Conclusion
Cantilever racks provide an efficient storage solution for heavy and lengthy items in industrial settings. Regular inspections, proper specifications, and safety considerations are crucial for maintaining rack integrity. By following these guidelines and consulting with reputable rack companies, businesses can optimize storage efficiency and ensure a safe workplace environment.
