Rack systems, forklifts and space efficiency

Get more out of your warehouse!

You can realise many different designs of storage systems with the racks from GALLER. Depending on the available space, hall height or requirements for article access, you will find the optimum solution for your personal requirements with our portfolio.

Space utilisation and rack operation

  • How a rack is operated determines the storage capacity for a given space
  • The aisle width of the floor conveyor system influences the degree of space utilisation of the racks
  • A conventional hall is recommended for heights up to 10 m, and a rack silo above that.
  • With the rack systems from GALLER you optimise your warehouse taking into account space, hall height, article access and throughput.

How many pallet storage locations fit in a given space?

Comparison of the pallet rack systems

Multi-storage pallet rack and front loader

Storage height: approx. 7.0 m

Storage area: approx. 350 ㎡

Multi-storage pallet rack, the most widely used racking system, allows direct access to each unit load. Space utilisation approx. 45%

216 pallets

Multi-storage pallet rack and wide aisle forklift

Storage height: approx. 7.0 m

Storage area: approx. 350 ㎡

Multi-storage pallet rack, the most widely used racking system, allows direct access to each unit load. Space utilisation approx. 45%

288 pallets

Multi-storage pallet rack and reach truck

Storage height: approx. 7.0 m

Storage area: approx. 350 ㎡

Multi-storage pallet rack, the most widely used racking system, allows direct access to each unit load. Space utilisation approx. 45%

384 pallets

Flow rack

Storage height: approx. 7.0 m

Storage area: approx. 350 ㎡

Storage and retrieval take place on the opposite sides of the rack. The pallets are placed on slightly inclined roller conveyors so that they move automatically to the removal side. Storage/retrieval is carried out according to the “First In – First Out” (FIFO) principle and is therefore particularly suitable for goods with expiry dates or for batch monitoring. The space utilisation is 85 percent.

360 pallets

Push Back rack

Storage height: approx. 7.0 m

Storage area: approx. 350 ㎡

The design is similar to that of a flow rack, however, storage and retrieval take place from the same side according to the “Last In – First Out” (LIFO) principle – the pallets are pushed into the channels. This makes very space-saving, compact storage possible. Push-back racks can also be equipped with trolleys on which the unit loads are placed. This makes the system independent of pallet type and quality; the goods are protected against damage.

480 pallets

Drive-in rack

Storage height: approx. 7.0 m

Storage area: approx. 350 ㎡

The pallets are deposited in several adjacent channels, each on two continuous supports. The industrial truck enters the channels for this purpose. Drive-in racks are mainly used for the storage of similar bulk items. The space utilisation of approx. 85 percent is particularly high.

720 pallets

Single-storage rack

Storage height: approx. 7.0 m

Storage area: approx. 350 ㎡

Only one unit load per compartment is stored between two rack uprights on each level. Angle profiles mounted in the depth direction function as supports. Heavy goods can also be stored safely up to great heights. This is particularly advantageous if order picking should be carried out directly from the pallet or from the pallet cage.

360 pallets

Mobile Racks

Storage height: approx. 7.0 m

Storage area: approx. 350 ㎡

The racks are mounted on traversing trolleys and stand close together. Only the currently required rack aisle opens in each case – in this way, the storage capacity can be increased by up to 100 percent compared to the conventional pallet rack. However, the high space utilisation contrasts with a low handling rate.

672 pallets

Narrow aisle storage

Storage height: approx. 7.0 m

Storage area: approx. 350 ㎡

The combination of narrow aisle width and high construction achieves a higher space utilisation (approx. 55 percent). Handling is performed using special narrow aisle forklifts.

1152 pallets

High-bay rack, single-depth storage

Storage height: approx. 16.0 m

Storage area: approx. 350 ㎡

As with the classic multi-storage system, access to each unit load is also guaranteed here. The handling is carried out via an aisle-bound AS/RS or, alternatively, via rail-guided AS/RS.

1584 pallets

High-bay rack, double-depth storage

Storage height: approx. 16.0 m

Storage area: approx. 350 ㎡

Here, two pallets are stored one behind the other. For this purpose, the pallets are either set down on Top Heads or on height-offset pallet beams. Operation is done using AS/RS with telescopic fork. This saves one rack aisle – the space utilisation increases by approx. 25% compared to single-depth storage.

2112 pallets

High-bay rack, channel storage

Storage height: approx. 16.0 m

Storage area: approx. 350 ㎡

Here, several storage units are stored one behind the other in inclined channels, with storage and retrieval from one side. Therefore, direct access to individual pallets is not possible. Channel storage is particularly suitable for a small variety of items with a large volume. The space utilisation is approx. 85 percent.

1540 pallets

Rack silo

Storage height: approx. 16.0 m

Storage area: approx. 350 ㎡

With the silo design, the rack construction also supports the roof and walls – this saves construction costs and reduces the project time. With the GALLER rack systems, channel storage systems up to 30 metres high or multi-storage pallet racks up to around 22 metres high can thus be realised. The operation is carried out via high-rack stackers or automated storage and retrieval systems, the space utilisation is approx. 60 percent.
