cantilever racks
The term cantilever rack refers to racks that are used to store long goods, ring-shaped goods, and plates or discs safely and clearly. Cantilever racks are available with one-sided or two-sided access.

structure and load-bearing capacity
Cantilever racks are classified as heavy-duty racks. Like other long goods racks, they are used for storing extra-long goods: strips, panels, slats, pipes and others.
Cantilever racks consist of a robust frame to which the arms are attached horizontally. These are ideally equipped with roll protection. The so-called cantilever arms serve as a support for lying goods or as a divider for standing goods. They also function as supports for shelves.
Load capacity: Cantilever racks are designed for heavy loads. Therefore, almost all parts of the rack are made of sturdy steel or sheet steel, including the connections between the cantilever arms and the rack body. In addition, the racks are powder-coated, which makes them even more robust against impacts, blows or external weather influences. When purchasing, you should pay attention to the distinction between shelf load and bay load in terms of load capacity; in this case, the arm load and the upright load.
- Arm load: load-bearing capacity of an arm; dependent on the total capacity of the cantilever arms on the corresponding level
- Stand load: Maximum load capacity of a stand
advantages and disadvantages
Cantilever racks are ideal for storing heavy, long and bulky loads safely and in a clear manner. The advantage is that high load capacities can be achieved (~ 630 kg/arm). The loads are also secured by a roll-off protection. Another advantage is easy access to the goods. The racks can also be used flexibly:
- Using two-sided shelves as room dividers
- Installation of one-sided shelves on walls
- Individual determination regarding the arrangement of cantilevers
- Subsequent changes regarding the arrangement of the cantilevers possible
- Can be used at great heights - thanks to ground anchoring
Disadvantages of cantilever racks are, on the one hand, the large amount of space required - due to the protruding cantilever arms and the removal of goods - and, on the other hand, the limited amount of usable stored goods.
- Only suitable for goods that are insensitive to dirt or other external influences (open storage)
- Limited automation options
- Design only allows the LIFO storage strategy
mounting type
Cantilever racks are available either directly with welded arms or as a combination of plug-in and screw assembly.
Pre-welded cantilevers have the advantage that they are pre-assembled and easy and quick to set up. They are also very stable. The disadvantage is that they can no longer be individually adjusted after delivery.
With plug-and-screw assembly, assembly is comparatively simple. It is also expandable and can be modified at any time. This type of assembly offers great stability and also great flexibility in terms of the number and height of the shelf levels. The disadvantages are that the assembly has to be carried out by the customer and any modifications are very complex.
access
Cantilever racks can be installed on one or both sides and are ideal for mechanical and manual goods picking .
Single-sided cantilever racks with L-frames for one-sided access have the advantage of being very stable, provided the back wall is fixed to a wall. They therefore require comparatively little space, but are also less resilient than double-sided cantilever racks.
Double-sided cantilever racks with T-frames for access from both sides require more space. However, they also offer more storage space per cantilever rack.
