What is a Cantilever Rack?

Hand pallet trucks operate hydraulically to allow heavy objects to be lifted.

A cantilever shelving is a storage system that employs a cantilever support arrangement for its individual shelving or shelving. A cantilever system is one in which a load-bearing beam is supported at one end, with no other external restraints. Cantilever rack systems have individual rack brackets attached at one end to vertical members using a slot and tag or bolted fittings. There is no other oblique or vertical support involved, which allows the racks to easily accommodate materials longer than the rack span. Cantilever racks can be constructed as single-sided 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 lintels, lintels and other supports. This type of structure is extremely strong, although it looks a little fragile and can support considerable weight. Loads on the horizontal support are transported to the vertical support contact point, where they are distributed and resisted by a combination of moment and shear forces.

In the field of material handling equipment, the cantilever rack system offers several distinct advantages over other rack and shelf arrangements. Due to the absence of vertical or oblique supports, a cantilever rack can be used to store loads much wider than its own span. Loading and unloading can also be done from the front of the rack, using equipment such as pallet trucks and forklifts. This makes the cantilever rack arrangement an obvious choice for facilities that store lumber, pipe, steel stock and board.

These rack systems can be installed as a freestanding structure or bolted to a suitable wall. In freestanding applications, these racks can be used in a single or double sided configuration with back-to-back shelves. Cantilever rack systems allow users to maximize available floor space and are available in a variety of sizes and load capacities to meet a wide variety of storage needs. Due to their simplicity, they are also among the most cost-effective of all rack types.

An added benefit of these storage solutions is their speed and ease of assembly. Many smaller cantilever rack systems use a slot and tag mounting method consisting of a tag on the horizontal support that locks into a corresponding slot on the vertical member. This allows for quick and easy installation and simplifies the storage of the racks themselves if they are no longer needed. Larger systems often use bolted horizontal beams, but remain simple and quick to build. Cantilever units are also often modular by design, allowing multiple units to be bolted together to extend an existing system.
