Cantilever Rack

Forklift-friendly rack systems

Cantilever racks are unique among racks in that they employ vertical supports at the rear of the rack only, with “arms” extending from the columns at the back of the system to support loads.

The benefit of this configuration is wide-open access at the front of the rack for loading and storing a wide variety of long, bulky or awkward loads.  The arms, which are available in a wide variety of styles and sizes, are easily reconfigured to make this an ideal solution for storing items such as furniture and building materials.

Cantilever racks can be used indoors or outdoors. With the addition of decking, cantilever racks can also provide storage similar to pallet racking, with the advantage that, with no front column, there is easy access for loading and unloading as each storage slot is immediately accessible. This can lower your handling time and costs. The arms provide for adjustable rack openings that easily accommodate various load dimensions.

Steel King offers a variety of cantilever systems, including standard duty, light duty, and I-beam cantilever racks.

 

Cantilever light

Light Duty

Light duty cantilever racks are designed for use in hand loading situations. They’re constructed of high strength steel columns (62,000 psi), contain bolted connections and have welded column-to-base connections. They’re adjustable vertically in 2″ increments. Can be built in either single or double sided configurations.

 

Cantilever – standard

Standard Duty

Standard duty cantilever racks are designed to hold standard to heavy loads. They’re available with many arm size and type options to meet a variety of storage needs. Arms are adjustable in 3″ increments. They contain bolted arm connections with a heavy arm connector plate as well as welded column-to-base connections. The cantilever shelving units can be built in either single or double sided configurations.

 

I-Beam

I-Beam cantilever racks allow access from both sides. This design saves horizontal space normally lost to rack structure, reduces fork truck damage and allows for faster load and unload times. They’re constructed of structural steel with a 50,000 psi minimum yield. With freestanding heights up to 30′ and 8′ arm lengths, the provide a lot of storage options. Arms adjust vertically in 4″ increments. With a heavy arm connector plate and bolted column-to-base connections, they’re a rugged addition to your storage line up.

The cantilever storage system easily stores:

  • Steel bars
  • Wood
  • Plywood
  • Lumber
  • Furniture
  • Appliances
  • Pipe
  • Structural members
  • Sheet steel
  • Tubing
  • Doors
  • Boxes
  • Pallets
  • Conduit
  • Extrusions
  • Rolls
  • Building materials

Holds standard to heavy loads
Standard-duty cantilever racks offer efficient, organized storage of longer, oddly-sized materials. These racks are heavily constructed with many arm size and type options to meet a variety of storage needs. Adjustable vertically in 3” increments, these racks have bolted arm connections with a heavy arm connector plate as well as welded column-to-base connections.

Safety factors for columns and arms – 1.56 minimum (1.4 / 0.9 – based on LRFD design)

Cost effective storage
Light-duty cantilever racks are designed for use in hand loading situations. Though used for light-duty, these Steel King cantilever racks are constructed of 62,000 psi high strength steel columns, contain bolted connections, have column-to-base welded bases and are adjustable vertically in 2” increments.
