What Is A Cantilever?

Cantilever racking systems offer the ideal solution for storing all types of long and heavy products, regardless of whether the storage is horizontal or vertical. They provide great space efficiency for warehouses.

Cantilever racks are characterized by connection elements that appear only at the back and are perpendicularly attached. In front, the shelf is accessible horizontally, access being restricted only by the shelves above. There are key features of this type of racking system design that each operator needs to know.

Console racks and the principle of the lever

For regular shelving systems such as pallet racks, the bottom of the shelves rests on at least four support points that drive the pressure force towards the floor. While they are easy to assemble, standard racks are susceptible to lateral overturning, for which reason proper reinforcement (i.e. diagonal bars, solid angular supports or posterior walls on the entire back surface) is required.

Cantilever warehouse shelving Denver racks do not have vertical pillars at the front; because of this, there is more pressure on the reinforcement bar supporting the racks: the pressure on the rear of the shelf is directed downward.

At the front, however, the pressure forces work in the opposite direction: they create a torsion load that turns the reinforcement bars into very effective levers. The wider the shelves are, the stronger the leverage effect. In terms of static load, cantilever racks are subject to very special requirements.

Loads stored on this type of shelving will be handled by lifting systems, such as forklift cranes or simple forklifts, depending on the weight and dimensions of the load to be stored, as well as the height of the shelf itself.

The structure of cantilever racks consists of vertical columns with one or two horizontal beams at the base, to ensure stability. A number of shelves are attached to the columns, where the load is placed. They are made of hot-rolled metal and can be attached to columns at different heights.

These shelves can be: unilateral (single-sided), bilateral (access from both sides) and may have accessories, including console end stops (to prevent profiles from rolling and dropping), metallic shelving, grid shelving or protection pillars.

Cantilever racks can also be installed outside warehouses. The positioning of racks on the pillars is adjustable, thus ensuring the adaptability of the system to different products. Installing and disassembling a cantilever rack system is simple.

The main benefits

– Intelligent use of storage space. Cantilever rack systems maximize the storage potential of your warehouse.

– Lower cost of warehousing. In addition to their main advantage mentioned above, cantilever rack systems also lower the storage costs considerably

– Durability. Cantilever racks are typically made of quality materials, able to bear heavy loads and provide a long service life.


Remember that any storage space, no matter how small, may be spacious enough for your needs when you use cantilever rack systems. In addition, the products will be safely stored on them, so you do not need to worry about accidental damage to your inventory.
