For a company that stores large quantities of different stock items, finding sufficient space is often a serious problem. Further compounding their difficulties is the fact that storage space is becoming increasingly expensive in the wake of rising demand, even assuming that it might be feasible to move their operations to larger premises. Left with no option other than to maximise the use of whatever space they do have, one possible solution is to install VNA racking.
With this type of storage system, additional space is made available to accommodate extra stock items by reducing the space taken up by unnecessarily wide aisles in order to accommodate more racks. This also explains the use of the 3-letter acronym which actually stands for “very narrow aisle”. The increased storage space resulting from the reduced width of the aisles can be further increased, if required, by extending the racks vertically as well as increasing the number of rows. This combination could result in an increased storage capacity of up to 40% or more and will more than justify the decision to convert to VNA racking.
Naturally, the introduction of a very-narrow-aisle system is certain to call for a revision of the existing picking and packing procedures. Standard forklifts will not be able to operate in the more confined spaces, while manual handling would leave most of the vertical storage space inaccessible. Instead, either manually operated vehicles – in which passage is controlled by means of guide rails – or automated systems will be necessary to ensure safe and efficient use and maximum benefit. While this will give rise to additional cost, if you decide to go ahead with the installation of a VNA racking system, it should still result in considerable savings when taking into account the short-term cost of a move to larger premises and the long-term cost of the increased rent or loan repayments.
Apart from this revised logistical need, the use of very narrow aisles in combination with the increase in storage height also creates some new physical requirements. The most important of these will be to ensure that the flooring is sufficiently strong to withstand the extra load and its more concentrated distribution. In addition to providing the extra stability for the much taller stacks, and to ensure smooth passage for vehicles between rows, the floor surface will also need to be rendered free of dents and bumps. Before making the move to a VNA racking system, to ensure safety in the longer term, it might be wise to resurface your warehouse area.
Unlike merely installing a few rows of boltless shelving, converting to the use of very narrow aisles is not an undertaking that can be tackled as a DIY project. Long before reaching the implementation stage, it will be necessary to determine both your current and potential future needs in order to ensure an adequate solution. While you may have a very accurate idea of those needs, it might be better to entrust the decision on how best to fulfil them to an expert, A leader in the field of specialised storage solutions, Krost has the quality products and experience to handle your VNA racking solution.
