Cantilever Racks
Cantilever rack is a storage system which employs a cantilever support arrangement for its individual racks or shelves. Cantilever system is one where a load bearing beam is supported at one end only with no other external braces. Cantilever rack systems have individual rack supports attached at one end to upright members by means of slot and tag or bolt-on fixtures. There are no other oblique or vertical supports involved which allows the racks to easily accommodate materials longer than the rack span. Cantilever racks may be constructed as single- or double-sided units and can be easily combined as modular assemblies.
Cantilever construction has been used for centuries in architecture and construction due to the aesthetic and practical possibilities offered by the absence of spars, lintels, and other supports. This type of structure is extremely strong even if it seems somewhat flimsy and can bear considerable weight. Loads on the horizontal support are carried to the vertical support contact point where they are distributed and resisted by a combination of moment and shear stress forces.
