Understanding Cantilever Arms: The Backbone of Cantilever Rack Systems

by | Nov 7, 2023 | Blogs

In today’s fast-paced industrial world, efficient storage solutions are crucial to maintaining organized and accessible inventory management. One such solution that has gained popularity is the Cantilever Rack System. At the heart of this storage system lies the Cantilever Arms, which play a vital role in supporting and organizing a wide range of materials. In this article, we will delve into the intricacies of Cantilever Arms, their importance, types, and the benefits they offer within Cantilever Rack Systems.

What are Cantilever Rack Systems?

Cantilever Arms are the horizontal load-bearing components of a Cantilever Rack System. These arms extend outward from vertical columns and provide a sturdy platform for the storage of long, bulky, and irregularly shaped items such as lumber, pipes, tubing, and steel bars. Their design allows for easy access and efficient loading and unloading of materials.

The Types of Cantilever Arms

Cantilever Arms come in various types, each designed to suit specific storage needs:

1. Straight Arms

Straight Arms are the most common type and are ideal for storing uniform and evenly distributed loads. They provide uninterrupted, flat storage surfaces.

2. Inclined Arms

Inclined Arms are designed with a slight upward slope to prevent materials from rolling off. They are suitable for cylindrical objects like pipes or rolls.

3. Double-Sided Arms

Double-sided arms allow storage on both sides of the rack, maximizing storage space. This design is excellent for items with varying lengths.

4. Heavy-Duty Arms

Heavy-duty arms are reinforced to handle cumbersome loads. They are essential for warehouses dealing with robust and weighty materials.

The Benefits of Cantilever Arms

Cantilever Arms offer numerous advantages within Cantilever Rack Systems:

a. Versatility

Cantilever Arms can be adjusted to various heights and angles, making them adaptable for different storage needs.

b. Easy Accessibility

The open design of Cantilever Arms ensures easy access to materials, simplifying the loading and unloading process.

c. Space Efficiency

Cantilever Rack Systems optimize vertical space and are perfect for high-ceiling warehouses. The lack of horizontal beams allows for the storage of longer items.

d. Durability

Cantilever Arms are typically constructed from robust materials, ensuring longevity and safety.

How to Properly Use Cantilever Arms?

To make the most of Cantilever Arms in your storage system, consider the following best practices:

1. Organize by Size

Sort and store materials on Cantilever Arms based on their size and weight. Heavier items should be placed on the lower arms to maintain stability.

2. Proper Spacing

Maintain adequate spacing between Cantilever Arms to prevent interference when loading and unloading materials.

3. Regular Inspection

Regularly inspect Cantilever Arms for signs of wear and tear. Replace any damaged arms promptly to maintain safety and functionality.

4. Load Distribution

Distribute loads evenly across Cantilever Arms to prevent overloading and maintain balance.

5. Labeling

Use clear labeling to identify the contents of each Cantilever Arm for easy retrieval.


  1. What are Cantilever Arms used for? Cantilever Arms are used for storing long, bulky, and irregularly shaped items like lumber, pipes, and steel bars in Cantilever Rack Systems.
  2. Are Cantilever Arms adjustable? Yes, Cantilever Arms are adjustable, allowing you to customize the storage space according to your needs.
  3. What are the different types of Cantilever Arms available? There are various Cantilever Arms, including Straight Arms, Inclined Arms, Double-Sided Arms, and Heavy-Duty Arms, each designed for specific storage requirements.
  4. How do Cantilever Arms optimize storage space? Cantilever Arms maximize vertical space by eliminating the need for horizontal beams, making them ideal for high-ceiling warehouses.
  5. Why is regular inspection of Cantilever Arms important? Regular inspection helps ensure the safety and functionality of the Cantilever Arms and prevents accidents due to wear and tear.

How to Build a Cantilever Rack System

In today’s fast-paced industrial landscape, optimizing your warehouse storage is crucial to maintaining efficient operations. One effective solution to efficiently store long and bulky items like pipes, lumber, or steel bars is the cantilever rack system. In this comprehensive guide, we will delve into the ins and outs of building a cantilever rack system, determining the required cantilever arm capacities, and establishing the appropriate cantilever bracing lengths.

Building a Cantilever Rack System

  1. Gather the Necessary Tools and Materials: To start the project, you’ll need the following materials: vertical columns, horizontal arms, and base units. Ensure you have the proper tools, such as a level, tape measure, and a wrench.
  2. Plan the Layout: Decide where you want to install the cantilever rack system. Consider factors like available space, accessibility, and the type of items you plan to store.
  3. Assemble the Vertical Columns: Position the vertical columns at equal intervals along the intended length of the rack. Use a level to ensure they are perfectly upright.
  4. Attach the Horizontal Arms: Slide the horizontal arms into the column’s perforations and secure them using the provided hardware. Please make sure they are level and evenly spaced.
  5. Install the Base Units: The base units provide stability to the system. Bolt them to the floor, ensuring they are aligned with the vertical columns.
  6. Test the Stability: Before loading your items, test the rack’s stability by applying some weight to ensure it can support the intended load.

Determining the Required Cantilever Arm Capacities

Cantilever arm capacities are a critical consideration when designing your rack system. To ensure safety and efficiency, you must determine the right capacities for your specific needs.

Consider the Load

  1. Know Your Items: Understand the weight and dimensions of the items you plan to store on the cantilever rack. This information is crucial for selecting the appropriate arm capacities.
  2. Consult Manufacturers’ Guidelines: Manufacturers provide load capacity charts that specify the maximum load each arm can support. Always follow these guidelines.

Calculating Load Capacity

  1. Distribute Weight Evenly: To maintain balance, distribute the load evenly across the arms and ensure that no single arm exceeds its capacity.
  2. Factor in Safety Margins: It’s advisable to choose arms with a capacity higher than what you expect to store. Safety margins are essential.


Cantilever Arms are the backbone of Cantilever Rack Systems, providing efficient and organized storage solutions for a wide range of materials. Their versatility, easy accessibility, and space efficiency make them a valuable asset in various industries. By understanding their types, benefits, and best practices for use, you can maximize the utility of Cantilever Arms in your warehouse or storage facility.
