How to Buy Cantilever Racks

Structural steel cantilever rack storage systems are multi-level, high density storage racks designed to handle hundreds of  different types and sizes of products with freedom from column obstruction / upright interference. Cantilever storage racks offer more flexibility for placing and removing products. Cantilever offers the best solution when unobstructed access is required for longer dimensional products, such as carpet, lumber, Furniture, bar/plate stock and pipe. Varying & oversized products in legth can be stored using cantilever rack without loosing capacity as you can increase capacity / level by puting towers closer. Cantilever racks can also be decked for use with odd–sized bundles, crates or bulk items like furniture. Cantilever Rack consists of a series of structural steel arms bolted to large structural steel columns. Anchored by substantial bases and stabilizing cross braces along its back edge, this system is both strong and highly adjustable.
 
APR STRUCTURAL CANTILEVER RACK OFFERS FOLLOWING ADVANTAGES
 
  • Strong and durable structural steel construction
  • No front posts – unrestricted access to your product
  • Arms are vertically adjustable on  4” centers to accommodate various load heights
  • Efficient use of vertical space
  • Easily store materials of varying dimensions
  • Uprights / Columns punched on both sides for single or double sided storage
  • Decking options are available
  • Inside or outside storage
  • Bolted base, arm and brace connections
  • A variety arm sizes for different loads capacities
  • Pole sockets & End poles available

DETERMINE LENGTH OF THE ARMS:-
 
•    Arm vertical spacing is dependent on the load size and lift clearance required
•    Arm lengths depends on the depth of the product stored
•    Various sizes are available depending on load size and required capacity
 
Determine how many arms are required to support your load. Base this on the maximum lateral spacing of arms (due to load rigidity or weight) and in conjunction with the Arm Capacity Chart shown below. Individual arm capacity is determined by dividing the total load weight by the number of supporting arms. Arm length equals the depth of your load. Arm capacities are based upon uniform loads.

You can determine the number of load levels per upright considering:
 
  1. Maximum lift capabilities of your fork lift truck.
  2. Unobstructed vertical space available.
  3. Subtract the base height from the maximum lift height. Divide this height by the sum of: (one load height + 5” clearance + the height of one arm). This will equal the number of loads below the top arm that can be stored within the lifting capabilities of your truck. Check for unobstructed vertical space, if adding one more load height exceeds vertical space available, reduce arm levels by one.

DETERMINE HEIGHT:-
 
Determine the Upright capacity by multiplying the desired number of arm levels by the capacity of the selected arms. A load can be stored on the base, however, this load is not included in the Upright capacity.
 
Minimum Upright height equal to:-
 
  1. The total number of arms per side multiplied by the individual arm height, plus...
  2. The base Height plus..
  3. The space between the arms (load height plus 4” - 6” clearance) multiplied by the number of spaces, plus...
  4. 4” minimum above the top arm. If you want the upright to be a back support for the top load, add in the desired height.

 DETERMINE ARM SPACING:-
 
The distance between uprights determines the bracing width. If you have two arms under your load the Brace Panel would be one-half the load length, three arms under the load would be one-third the load length.

BRACING POSITION & SPACING:-
 
Lateral stability and spacing of the columns is accomplished with factory welded Vertical X-Brace Panels and Horizontals Brace members.
X-Brace Panels, are required in each end bay of any row, and in alternate interior bays. Factory welded attached bracing clips will properly position the bracing on the column.
See the Bracing Pattern chart for various column heights. To ascertain bracing required for in-between sizes select next larger size.
Straight Brace/ Single angle bracing is configured as shown in Bracing Position pattern figure.

CALCULATING REQUIREMENTS OF STRAIGHT BRACES / X BRACES:-
 
Height of upright / column will decide requirements of x-bracing or straight bracing. Following picture will self explain how many x-braces or straight braces required for desired column / upright Height.
