If you are looking for New or Used Cantilever Racking system for your warehouse or outdoor storage facility look no further. MHE has over 1,000 of Beams, Towers, Bases and Starter Bays on site at our location. From time to time we acquire complete cantilever rack systems never installed and never used. This gives you the quality of new product at the price of used cantilever racks.

Compared to selective pallet rack designs, items are more accessible meaning easier forklift loading and retrieval. All of this equates to a significant increase in storage capacity and handling efficiencies.
There are over 1,000 variations of cantilever racks positions and storage options we can offer. Most people are not sure if they need inclined or straight beams and/ or what lengths while maintaining the stability to hold product. Give us a call and one of our staff of highly trained, experienced pros can help you understand what size, load capabilities, beam lengths and warehouse layout you will need to maximize your space for storage.
You may find it useful to know that cantilever racking systems are available to accommodate especially stressful loads, such as those common in the steel industry. In such super-heavy duty designs, the columns are manufactured from high strength steel, then tapered to compensate for column deflection, and pre-punched on both sides for conversion from single to double-sided rack units. Further, cantilever arms also are tapered to compensate for deflection, and the steel base is welded to the column to provide a stable foundation.
A Cantilever Rack is comprised of three components:
An ideal system for storing furniture, steel bars, pipes & tubing, or any other long, heavy items too large for other industrial storage solutions, cantilever racks are a series of arms, uprights, and bracers that provide instant accessibility to both full cargo loads and individual pieces. The open design allows forklifts to easily take loads off and put loads back on, and the modular nature of the racks allows for easy expansion if storage requirements change.
These components must be ordered in the appropriate quantities and capacities.
Uprights consist of a vertical column and a horizontal base which is bolted to a 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 the base used.
Holes are provided in the base to anchor the upright to the floor. Uprights must never be attached to walls, columns or other structures.
Cantilever arms are the heart of the rack system. Proper selection can make or break a successful storage plan. Shelving 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. Standard arm color is gray.
Straight ArmStraight 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 Arm
Inclined arms have a pitch of 20 degrees or approximately 4.36" per foot.
Hair Pin Keeper
The hair pin keeper permits instant adjustability and is easily inserted and removed for adjustment of arm height. Lips are available on all arms.

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.
1. Determine the number and spacing of arms.
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 are 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 centerline to upright centerline. Failure to observe this measure may cause an overload condition on the arms.
2. Determine the length of the arms.
The depth of the load should never exceed the length of the arm. A 48" wide bundle of plywood requires a 48" long arm, bundles of steel 24" wide require a 24" arm and so on. Rated arm capacities may be seriously diminished if proper loading techniques are not observed. Figures B1, B2 and B3 illustrate correct and incorrect arm loading.
3.Determine the height of the upright.
When determining the height of the upright it is important to consider the ceiling height, forklift reach, sprinkler systems and other factors, such as local building codes, that might effect the overall height.
