One of the main challenges who are faced with logistics companies is the storage of their products. You have to optimize the space to the maximum, make the storage and dispatch of merchandise easier and, on the other hand, gain security in processes that in some cases can be complex. Push back shelves are one of the best options for the warehouse, and in this post we explain more details.
More about the push back shelf: what it is and all its advantages
This type of shelving, increasingly demanded by companies in the sector, is what allows compact storage by accumulation.
In this system, different pallets are stored in depth, which are deposited and withdrawn from the same loading and unloading aisle, on roller tracks placed with a slight slope that allows them to move by gravity.
It is the forklift that is in charge of pushing the merchandise towards the bottom of the channel, so that each new pallet to be stored pushes all the others already stored towards the bottom.
For unloading, the small unevenness of the rollers, usually a 4% slope, causes the others to drop by gravity when removing a pallet until another pallet is ready in the unloading position.
At this point, what are the benefits of this type of installation?
- It is a LIFO system (last in, first out), ideal for non-perishable products, where the last pallet to enter is the first to leave.
- It allows stock control in warehouses with a wide variety of products, since a different reference number can be stored on each level.
- The fact of only needing one aisle increases the storage density, making the most of the space.
- Unlike the compact drive-in system, the forklift does not have to work inside the installation, which substantially reduces loading and unloading time and, what is more important, drastically minimizes the possibility of the forklift colliding with the shelf.
Finally, in addition to all the above advantages and due to the rise of e-commerce, the facility can be equipped with a first level of dynamic box picking or directly on pallets to be combined with our pick to light systems.
