A frame is a basic component of the long span shelving. This part consists of 2 upright profiles that are supported by a base plate. The profiles are connected to each other by a series of diagonal and horizontal C-profiles. The C-profiles give this component the appearance of a ladder, but at the same time provide stability.
Frames have different upright profiles depending on the requested capacity and configuration of the long span shelving. The depth and height of the frames will also vary based on the desired configuration of your storage system. The frames will always be adapted to the specific requirements of your warehouse layout.
The base plates are also a basic component of the long span shelving. Without the base plates, a wide span shelf cannot be anchored to the ground. Whether or not to anchor the shelf structure depends on the processes that take place around the long span shelving system. The base plates are connected to the frame using various bolts and nuts. This creates a solid connection between the frame and the base plate.
The beams are the last basic components of the long span shelving. The frames stand stable on the ground thanks to their anchored or non-anchored base plates and are now connected to each other using beams. These beams serve the ultimate goal of the storage system; creating locations for the storage of goods.
Beams are usually placed in pairs; one at the front of the frame and one at the back. This way they form a platform on which a pallet can rest on both beams of the pair.
For the safe use of your storage system, beams are always provided with 2 safety pins. These are slid into specially provided holes at both ends of the beam. Thanks to an inventive rotating system, it is now no longer possible to accidentally lift the beam, the pins prevent this.
Beams come in a huge variety of sizes and types. The height of the beam determines, together with the type of construction and the steel thickness, the capacity. The width is adapted to the type of goods you need to store in your warehouse.
There are several options for protecting the basic components that ensure the stability of the long span shelving. However, the goal is always the same; reduce and/or stop the impact on the front of the frame.
The front of the frame is the part of the frame that is freely accessible in the aisle of the long span shelving. It is therefore possible to hit it with the forklift (or other machine) used in these aisles.
To stop the impact, you can use various freestanding protections. However, they must be anchored in the ground. You can also use protections that are placed on the frame itself. The latter are made of metal and connected to the frame by means of bolts and nuts.
Goods stored in long span shelving system are often too small to be supported by both beams. It will therefore often be opted to provide an extra connection between the pairs of beams in the form of a chipboard deck.
The beams that are used in combination with a chipboard deck have an adapted profile. This profile ensures that the chipboard and the front of the beam are flush and provide a flat surface.
If one has opted for the use of chipboard decking in combination with heavy goods or very deep racks, additional support may be required. This support is provided in the form of support profiles that are attached between the beams. The number of support profiles depends on the dimensions and the required capacity of the long span shelving.
In addition to chipboard decking, you can also opt for metal shelves. These are also provided with adapted beams that are flush with the beam providing a flat surface. The choice between wooden or metal shelves depends on the customer’s requirements, the dimensions and the required capacity of the long span shelving.
When storing very small goods they are often stacked on top of each other. To prevent the stacked goods from falling over and thus mixing different types of goods, metal dividers can be installed. These dividers are attached to the shelf by means of a bolt and nut connection.
When storing very long goods, it may be preferable to store these goods upright. This creates the risk that the goods will fall over and mix with other stored goods. In this case it is best to use tubular dividers that are mounted on a single beam (at the back of the long span shelving).
The connection of the tubular divider to the beam is done by means of a bolt and nut connection. The bolt will not go through the beam, but will pass under the beam and tighten the divider holder against the beam. This allows the dividers to be moved at any time as required by the storage layout.
Force repartition plate
Long span shelves that are loaded with all kinds of goods can collect a large total weight. This weight puts a point load on the surface through the foot plates. To spread this point load, one can use so-called force repartition plates. These are placed under the foot plates of the frame and are provided with holes for the placement of anchors.
To level out the appearance of the long span shelving you can opt for frame covers. These metal plates are mounted on the frames at the end of a row. Different sizes of cover plates allow us to completely cover any frame size.
