Basically, the Cantilever Shelves have three types that are mostly used in warehouses and industries for their storage needs.

• Roll-formed or light-duty Cantilever Shelves
• Medium-duty Cantilever Shelves
• Structural or Heavy-duty Cantilever Shelves

9-What Are The Differences Between Different Types Of Cantilever Shelves?

There are three basic types of Cantilever Shelves according to their usage.

Roll-formed or Light-duty Cantilever Shelves manufactured from the roll-formed steel can be made up to 7 feet (2m) high and can store a weight of up to 500 pounds (225 kg) per load-bearing arm.

Medium-duty Cantilever Shelves have the characteristics between light-duty and heavy-duty Cantilever Shelves that can store a weight of up to pounds (450kg) per load-bearing arm.

Structural or Heavy-duty Cantilever Shelves manufactured from structural steel and channel steel can be made up to 30 feet (10m) high and can store a weight of up to pounds ( kg) per load-bearing arm.

10- How Many Configurations Of The Cantilever Shelves Can Be Made?

One of the important features of the Cantilever Shelves is that they can be made for up to two-sided configurations.

You can directly access your stored products from both sides of the storage system.

Double-sided Cantilever Shelves increase your storage capacity up to 50% and decrease the number of aisles in your storage area.

Cantilever Shelves Configurations

11- What Is The Difference Between The Cantilever Shelves And Other Storage Systems?

The Cantilever Shelves are different from the other storage systems due to the following reasons.

• The Cantilever Shelves and other storage systems use different components for their production.
• Products are directly stored on load-bearing arms in the Cantilever Shelves whereas, other storage systems use beams or carts to store products on pallets.
• The Cantilever Shelves can be made of two-sided configurations, whereas; other storage systems can be made more than two pallets deep.
• You can use the Cantilever Shelves for storing long-size and awkwardly shaped products, whereas; you cannot store these types of products in other storage systems.
• You can use the Cantilever Shelves both indoor and outdoor whereas, other storage systems do not provide this facility.
• You can directly access your stored products in the Cantilever Shelves whereas, many other storage systems do not give direct access to the stored products.

13- How Much Weight Can Cantilever Shelves Hold?

The Cantilever Shelves are of different types, and each type has its own weight holding capacity.

This system uses load-bearing arms for holding the weight of loaded products, so the total weight of the loaded products divides by the total number of load-bearing arms holding that product.

Light-duty Cantilever Shelves can hold a weight of up to 500 pounds (225kg) per arm.

Medium-duty Cantilever Shelves can hold a weight of up to pounds (450 kg) per load-bearing arm.

14-Can You Store Long Flexible Products In The Cantilever Shelves?

Yes, the Cantilever Shelves can be used to store the long flexible products.

The facility of decreasing the distance between the upright columns or the addition of more load-bearing arms on the Cantilever Shelves allows the long flexible products to be stored very easily.

The more load-bearing arms holding the flexible product, the more stable is the product

15-How To Avoid Deflection Of The Flexible Products Stored On The Cantilever Shelves?

When you need to store long size and flexible products in the Cantilever Shelves, there is a great chance of deflection from the center that may cause undesirable pressure on the side of the load-bearing arms.

The deflection of the stored flexible products on the Cantilever Shelves can be avoided by adding more load-bearing arms under the stored product.

You can add more load-bearing arms with equal distances between the ends of the stored product that increases stability to the flexible product.

16-How Can You Test The Deflection Of The Loading Product On The Cantilever Shelves?

The deflection of the flexible products can be tested by placing the wooden blocks under the product on the floor before loading on the Cantilever Shelves.

You can carry on increasing the number of wooden blocks under the loading product at equal distances between the ends until you detect no deflection in the product.

When you feel no deflection in the product, the number of wooden blocks used will be the total number of load-bearing arms you should use for supporting the loading product on the Cantilever Shelves.

Deflection Of Flexible Products

17-What Is Lateral Spacing In The Cantilever Shelves?

Product deflection is a major problem when you want to store long-size goods on the Cantilever Shelves.

To avoid this difficulty, lateral spacing should be enough to provide complete stability to your stored products.

Lateral spacing is the distance between the two upright columns of the Cantilever Shelves and can be measured from the centers of both the uprights.
