Heavy duty cantilever racks for storage. For those who operate a warehouse, a factory, a large retailer or a distribution center, storage space is at a premium. To conserve space, vertical stacking of storage materials is necessary. For example, a storage facility that is 25 feet high and permits goods to be stacked four levels high will use one fourth of the square footage as a facility that stacks goods one level high.
Of course, it is inefficient to simply stack goods on top of each other, not to mention a risk of crushing of products placed at the bottom. This is why a system of racks is vital to a productive operation. With products placed on racks, product can be removed from any level quickly and safely.
There are a number of racking systems that are utilized. A post and shelf system is much like home shelving. For each unit, four corner posts support levels of horizontal shelves. This system makes for a stable rack system that can hold significant weight.
The drawback with such a system is that the posts can interfere with the operation of a pallet mover or a forklift. It often takes significant maneuvering to negotiate through the posts. Another drawback is that long items, such as lumber or piping, cannot be stored if the length of the items exceeds the length between the posts.
Cantilever racking on the other hand, provides a solution to the drawbacks of the post and shelf system. With cantilevered racks, a central post accepts cross members on either side of the post. Horizontal shelving is then placed on the cross members. Since the central support post is on the interior of the rack, there is no vertical obstruction to interfere with a forklift or pallet mover. Because a single post is used for two lengths of shelving, the number of support posts is reduced dramatically. Companies such as Simply Rack design and supply such systems.
Proper design of Cantilever racking systems is required to hold the heavy weights of the product to be stored. Support posts must be constructed of heavy duty steel or iron to ensure sufficient strength to hold heavy weight on either side of the post. The arms themselves must be properly designed and of quality material, since they will only be supported on one side.
Quality design normally includes a metal bracing system at 45 degree angles to the arm and the post. It may be a solid triangular piece welded between the arm and the post or is may be a heavy duty tube or bar. The fittings between the post and arms must be of precision tightness with little lag in the fitting. A loose fitting creates movement inside the joint, which can quickly erode the fitting and make the system unstable.
