Mobile Pallet Racking


Mobile racking is a specialist high-density system often designed for long-term storage of pallets or other heavy goods. It provides maximum storage capacity in minimal square foot requirements. by eliminating aisles and compacting ranges, it can store products in half of the space as conventional shelving.The racking runs are mounted on mobile bases, which run on rails up and down the storage area. The bases are electronically driven and are normally kept closed leaving one aisle for access.

Maximum use of floor space as only one operating aisle required

  • Good occupancy rates

  • 100% individual pallet access

  • Particularly suitable for temperature controlled stores

  • Non specialist handling equipment

  • Flexible in height/width of load unit

  • Random position allocation

Adjustable Pallet Racking (APR)


This storage system is one of the most commonly used palletised storage. It is consist of end frames and horizontal beams that their height can be adjust to suit the height of the pallet loads the need to be store. It is actually used for flat pallet but there are accessories that enable to store some particular type of unit load. APR is very ideal for any combined storage and order picking areas, APR can go up to 8M high.

Advantages

  • Inexpensive

  • Easily installed and flexible

  • Beam height is adjustable and could be dismantled and moved

  • Have to increase storage efficiency while maximising cost effectiveness

  • Damaged part can be easily replaced

  • Simple positive location recording can be used

  • low set up and equipment cost

Disadvantage

  • Fork truck give access to only 2 rows of racking

  • Poor utilisation of building space

  • For 8M racking height, chemically treated flat floor is needed

If I not wrong, the storage system that is used in Ikea Tampines (level 1) is this system wor.. hee hee..

Double Deep Pallet Racking

If you are looking for some other alternatives that is a bit similar like APR. you can consider double deep pallet racking. This racking system can used double deep reach trucks that the legs can fit into the structure. Bottom pallets are not left on the floor but rather supported on the beams. This system is very suitable fir line items having at least 2 pallets-worth of stock. It is quite popular in cold-room application and space that are limited.


Advantages

  • Better space utilisation than APR

  • Ehanced space utiliasation

Disadvantages

  • Some of the random access will be lost

  • Need to have double reach trucks

  • Loss of absolute FIFO

  • Poor visibility for truck drivers

LIVE STORAGE PALLET RACKING

The concept of first in-first out (FIFO) stock rotation is ideally satisfied by carton and pallet live storage. These storage systems may be lineside materials handling or warehouse based. Live storage is a high density storage medium suitable for many products such as books, videos and packaged pharmaceuticals. The pallets are stored in a block system on sloping roller conveyor tracks supported on pallet racking. Pallets are loaded from the top end and roll forward under the force of gravity when a pallet is retrieved from the bottom end.





The Principle of Pallet Live Storage

Benefits of live storage


  • Store and handle high volume rapid turnover stock

  • Provide continuous flow of components on first in-first out principle
  • Establish just-in-time materials provision system
  • Flexible system with adjustable, shelf heights, wheel pitch, track and guide widths - goods deposited at rear of bay travel to picking face by gravity on wheeled track

  • Tilted shelves - ease of access for stock picking
  • High throughput capability
  • Optimum filling ratio - High Density Storage

NARROW AISLE PALLET STORAGE

By allowing fork trucks to operate in aisle up to half the width required in conventional adjustable beam pallet racking, Narrow Aisle racking makes excellent use of floor space and maximises the height at which goods can be stacked. The pallets are accessed via specialist trucks, which are guided in the very narrow aisles by either low or high profile floor mounted rails or electronic wire guidance in the floor. As storage locations can be only accessed using specialized equipment, the security of valuable products is improved. Besides that, the sophisticated handling equipment improves the safety of load handling within the racking system.

Advances in fork lift trucks that can operate in aisles less than five feet wide have made possible the utilization of very narrow aisle (VNA) storage racks.

Narrow aisle installations require Pick-up and Deposit (P&D) stations to facilitate the safe and efficient handling of products into and out of the Very Narrow Aisle system.

Advantages


  • 100% accessibility to individual pallets

  • Configuration for maximum storage, density and efficiency

  • Specialist narrow aisle fork-lift trucks are required to work in the reduced aisle

  • Better space utilisation

  • Good occupancy rates

  • Heights of up to 14 m available

  • Flexible in height / width of the load

  • First-in-First-out can be achieved

  • Provides heavy duty storage with access to all pallet positions

DRIVE-IN PALLET RACKING

Drive-In racking is very ideal for high-density storage. It is frequently used in facilities with a low number of product lines. Pallets are stored in a block system with two blocks generally served by one operating aisle. It provides high-density and better cubic utilization storage. This is due to fewer aisles required which allows 75% more pallets stored in the same space.

Lift trucks drive into the rack to extract the first pallet they come to. This is "Last-In, First-Out" storage. It will enter the racking to load or retrieve pallets, which are stored on cantilevered rails running throughout the system. This is done because pallets can slide backwards on a continuous rail. Forklifts can drive into the rack to access pallets two or more deep.
Double Entry Racks - lift trucks can enter from both sides or a row of racks. The center of the rack row is stabilized by a beam.



Single Entry Racks - lift trucks can enter the rack from only one side.




When should we specify Drive-In Racks?

  • We've installed Drive-In and Drive-Through Racks in a number of cold storage applications, due to the need to store as many pallets as possible in as little expensive freezer space as possible.

  • When you have seasonal items that move quickly out of your inventory.
  • When you have a large amount of similar items that can be stored in a single pallet position and accessed last-in, first-out
  • If you don't store a wide variety of loads in the rack.

Benefits of Drive-In

  • Maximum Space Utilization
  • No aisles needed between rows of rack
  • High density storage can be achieved in a relatively small space
  • This style of racking is extremely cost effective, as there are very few components. There is also no need for expensive specialised handling equipment to use this system.

  • Drive-In is "first in last out" (great for seasonal moving items)

How to use??

Blog have been a very popular thing in the net but 5 storemen totally have no clue on how to use this system. suddenly we feel so venerable and helpless too. hope that next few days we will know how to use it and start posting next and informative posts wor!!

WELCOME!!!

HELLO!!!


Welcome all fellow humans that are interested in logistics storage systems. We are a group of 5 mad LOM students that are dedicated to help you to understand some of the storage systems that are avaliable in the industry. Feel free to look around and leave some comments of our blog. Thanks and take care wor!!!
