 Drive in Racking System
Drive in racking is by eliminating the various aisle and lanes to produce a higher density at the expense of selectivity. By removing lanes and aisle to produce higher density simply means that there are no gaps between each pallet. All pallets are stored pack together, so that means the first pallet in are the last to go out. So careful planning to be improvised is needed to know which pallets to go in first. Each pallet is supported so damaging from crushing is eliminated. In many applications, pallets are received and dispatched in batches so this will not be an prime advantage as compared to other racking systems. However, it is a good solution if storage capacity is a prime requirement of your warehouse.
Advantages
-Eliminating aisles and lanes produces a high storage density at the expense of selectivity
-Saves space
-Save cost
-Each pallet is supported so damage from crushing is eliminated
-Up to 85% floor utilization
Disadvantages
-Hard to retrieve products that are stored in first
-Careful planning of how to stored the products is needed
-More manpower needed as need to plan how to stored the product in order
Applications
It is ideally suitable to seasonal goods where input and output are at different times. Also when goods are dispatch in batches for examples soft drinks,
Paints and chemicals.
 Powered Mobile Racking System
The diagram on the left shows the racks are mounted upon a steel framed base which is attached with drive wheels running on tracks on the floor electrically. Thus, enables racks to be moved to create an access aisle. This in turns means that between each racks you only need one aisle, as the racks could be shifted so it will form another aisle. This saves up space of having many aisles which waste space. Thus, turns the space to storage space for more storage. The based is a diagonally braced structured, below which sits two bogies, with direct drive electric motors. Varying racks configurations and bogies types are available to suit single bay loads up to 15 tones and run lengths of up to 30 meters. Having no bolt passing the steel frame eliminates the needs of having regular safety checks on bolt torque. As well as increasing workers safety at work.
Advantages
-Save cost in the long run as it utilized almost 80% of the storage space
-Easy access to product for order pickers and also loading unloading equipments
-Having no bolts to move the pallet eliminates the need for safety checks on bolt torque
-Up to 80% floor utilization
Disadvantages
-Incurred high set up cost
-Needs aisle control systems
-Not suitable for short run production
Applications
It is particularly suitable for use in cold stores; high rental premises bulky multi product applications, palletized consumer goods and products. |
