Cantilever racking in Adelaide
This racking system has been designed for the storage of long products like timber, Gyprock sheeting, cladding sheets, piping and the like that are far too long to fit in traditional pallet racking. Even bulky items like white goods can be stored on this type of racking with the use of decking on the cantilever arms. The name cantilever refers to the arms that are fixed at one end only to the supporting upright post.
Why not use conventional selective pallet racking with really long beams then? Conventional racking can store thousands of kilograms of stock….right? Actually, selective pallet racking is generally for the storage of two pallets side by side. The most common beam lengths are 2600 or 2750mm wide and supporting 2000 – 3000 kg per level. The longer a selective pallet racking beam becomes the weaker it gets, and hence the load carrying capacity is reduced dramatically.
Cantilever racking has a distinct advantage over selective pallet racking. It offers open storage without any upright frames to restrict the length of product you intend to store. Products that are metres and metres long can be stored on cantilever rack as they are supported by a horizontal row of arms.
Cantilever racking is comprised of the following components:
- Upright posts which will vary in height and profile depending on load or whether it is supporting arms on one side or both and is bolted into a base that is either single or double sided.
- The cantilever arms attach to the post to support loads and can vary in length and load capacity. The arms can be either tilted back slightly or have a stop on the end of the arm to prevent items like pipe rolling off.
- The upright posts are spaced apart with bracing that offers the rack rigidity and flexibility in widths between the posts.
Cantilever racks can either be single or double sided or in long or short runs and are customised to suit your requirements. Single sided runs are normally installed against a wall with double sided runs requiring access from both sides. Even though single sided cantilever posts can look the same as double sided due to the common post design it is definitely not safe to attach arms to the back of a single sided cantilever rack
In order to work out load capacity of the arms and the distance between the upright posts a few factors must be considered. If you are storing rigid product like PVC piping or heavy sections of timber the satisfactory distance between posts may be 1500mm. Products like Gyprock sheeting, bundles of lighter timber profiles and light gauge sheeting will be subject to deflection if the post are too far apart and 900mm distance between posts may cure this.
An easy way to check for deflection is to place some timber bearers at a certain distance apart, test your load on them and adjust the distance until there is zero deflection. This will be the ideal lateral spacing between posts as excessive deflection could damage your product. The load should also overhang the outer or end arms by about half the distance of how far apart the upright post are.
To work out load capacity of each arm you simply measure the length of the product that you need to store and how many posts are required to support the product without deflection. For example, if you wanted to store 6m lengths of timber and the pack weight was 1000kg, you have worked out that four arms will support the load without deflection. Each arm will be supporting 250kg. The levels of arms you would need per post would determine how much load the post needs to carry.
When loading the arms it is important that the load does not protrude past the end of the arm length and is either centred on the arm or as close to the post as possible. The depth of the arm will be dictated by the size of the load the arm has to support
City Shelving has supplied and installed cantilever racking in Adelaide for many satisfied customers. Some of these customers have fully realised the storage potential of cantilever racking and gone on and changed over their storage systems to this type of racking. Due to the ease of arm adjustment the system is very flexible and adjusts to changing stock patterns.
