Cantilever Rack



Cantilever Rack is a freestanding storage unit with horizontal load carrying arms extending outward from a single vertical column. The absence of a vertical support on the outboard ends of the arms permits uninterrupted storage of long lengths of material.

Cantilever Rack is the ideal system for storing furniture, steel bars, pipe and tubing, lumber and other long, heavy items that must be kept off the floor...provides instant accessibility to one piece or a full load. Forklift easily loads off and on arms and bases. Being modular in nature, additional arms, uprights and braces may be added as storage requirements change.


Cantilever Rack is comprised of three components...




 UPRIGHTS consist of a vertical column and a horizontal base which is bolted to the column. A minimum of two uprights must be ordered to form a storage bay. Each edge of the column is punched vertically on 3" centers so it may be used as a single or double sided upright depending on the size of base used. NOTE: The arms must never be placed on the back side of a single sided upright and base. Standard upright and base color is gray.

 ARMS are the heart of the rack system. Proper selection can make or break a successful storage plan. MECO OMAHA offers straight arms (generally used for storing stable loads such as lumber, steel sheets, cartons and skids) and inclined arms (for cylindrical objects or loads that tend to roll forward). Arms can be adjusted on 3" centers up and down the upright and are available in lengths to 60" in a variety of capacities. The hair pin keeper permits instant adjustability and is easily inserted and removed for adjustment of arm height. Lips are available on all MECO OMAHA arms. Standard arm color is gray.

Straight arms up to 48" long have a minimum pitch of 3/8" per foot to compensate for deflection. 54" and 60" arms have a minimum pitch of 5/8" per foot.


Inclined arms have a pitch of 20° or approximately 4.36" per foot.



BRACE SETS  are structural channel members that are bolted between pairs of uprights to provide lateral stability to the rack system. X-bracing is utilized to increase the lateral stability of the taller (15' to 20') uprights. Brace lengths are measured from center-line of upright to center-line of the next upright and are sold in sets rather than individual pieces. Standard brace color is gray.




The key to a successful cantilever rack system is the answer to one question: What is the product (load) being stored? The answer must include the length, depth, height and weight of the product. Once this data is ascertained it becomes a simple matter to determine the required arms, uprights and braces.



The load must be supported by enough arms to prevent load deflection. Deflection may cause damage to the load being stored as well as the arms (figure A1). To detect deflection, place the load over two wooden blocks (to represent cantilever arms) as shown in figure A2. If deflection is not present it is acceptable to use a two arm system as long as this does not create an overload condition. If the load shows deflection use three blocks as shown in figure A3 or four blocks as in figure A4.

IMPORTANT: The load should overhang the end arms by one-half the distance from upright center-line to upright center-line. Failure to observe this measure may cause an overload condition on the arms.
