Types of Racking
Selective Pallet Racking
Selective Pallet Racking can be serviced by virtually any type of forklift including counterbalance and reach trucks. Requiring a relatively low capital investment, it is ideal where flexibility, access and speed of operation are the main objectives of the system. Selective Pallet Racking can also be easily adjusted or relocated at any time.
- Low Cost Solution
- Available headroom less than 10m
- Full selectivity required
Double Deep Pallet Racking
Double Deep Racking offers many companies a cost effective method of bulk storage. Storing pallets two deep cuts the number of access aisles required but does mean that access to the second pallet in the slot is restricted. It requires forklift trucks with double reach mechanisms, to place and retrieve pallets from the second slot in the racks.
- Two or more pallets of the same SKU
- Less than 10-15 pallets of the same SKU
- Several hundred pallets to justify extra handling costs
Narrow Aisle Racking
Although the capitol cost of Narrow Aisle Racking systems and their associated handling equipment is greater, there are usually significant savings in land and building costs.
- At least 2000 – 3000 pallets to justify extra handling equipment costs
- Movement rates for two or more aisles serviced by one machine
- Height minimum of 8m to maximum 14m
Non-Selective Racking Systems
Drive In Racking
Drive In Pallet Racking is the lowest cost most popular form of high density pallet storage. It can be serviced by a variety of forklifts including counterbalanced and reach trucks. While providing excellent storage capacity, Drive In Pallet Racking does restrict access, with the first pallet in being the last pallet out.
- Minimum of 10 pallets per SKU
- Sock rotation in batches acceptable
- Occupancy 60 – 70% based on type
Push Back Racking
Push Back Racking is an effective solution providing high-density storage where pallets are stored 2, 3 & 4 deep. Pallets are pushed back on inclined rails mounted inside the racking structure. As pallets are withdrawn the pallet behind automatically moves to the front position.
- Can have different SKU’s at each level for greater selectivity
- Enables picking from lower levels
- Reduces floor space requirement: good for coolrooms
Pallet Live Storage
With pallet Live Storage, pallets are stored on inclined tracks with rollers. As a pallet is removed, the pallet behind rolls gently into place.
- Automatic stock rotation, First in – First out
- Pallets self feed when one is removed
- Decline speed essential in long lanes
