Push back racks are high-density shelving systems that store large boxes or pallets that work with inclined rails for a last out, first in storage method. They offer good storage density and zero wasted space between boxes or palletized loads. Push back racks are the preferred method of high density storage because they offer increased efficiency and significantly save on space.
Push Back Racks
The mechanics of push back racks involves inclined rails that slope gently forward to force loads to replace the front load when it is removed by way of gravity, which forces them to slide forward. This allows the loads to travel to the forklift, not the other way around. Push back systems are widely implemented as pallet racks and are used anywhere pallets or large boxes are stored in high volumes, including manufacturing plants, shipping warehouses and storage facilities across a wide variety of industries. They store pallets anywhere from 2 to 9 deep, and require only one aisle since the pallets are loaded and unloaded in the same place. They are often several rows high and can be 30 feet or higher, and each cart can hold up to 3 thousand pounds at one time. In warehouse racking, the easy product access increases pick rates and decreases the amount of time it takes a forklift to find and remove a palleted load.
Since push back racks are designed to hold heavy pallets, boxes and cartons, they are constructed out of structural or roll formed frames that are able to handle a large amount of continuous weight. They are generally permanent and non-mobile, although the angle of the inclined rails is always adjustable. The primary benefit of push back rack systems is the fact that lift trucks are not required to drive into the system. This reduces the risk of rack damage, which extends the lifespan of the racks. While these systems are generally used for last in, first out storage, it is simple to rotate stock on a first in, first out basis as well. In order to do this, new loads must never be stored in front of older loads. Since every bay is accessible from a single aisle, this method is not difficult to operate. The interlocking carts prevent jamming and product damage, while a lip on the end rack prevents loads from falling off the rack when traveling to the front position. These systems are safe, easy to install and use, and work with standard lift trucks and therefore rack manufacturers supply these to a wide range of warehouses and storage facilities.
