2.- The currently most widely used load unit is indeed the pallet box of standardized dimensions and m nipulated by means of stacker trucks. At the other end

  
of the series of handling devices is the c content which receives bulk goods.

  
Goods transported on long journeys -surto

  
in international traffic - may undergo several load breaks during its transport passing from a loading system

  
to another: container - pallet - pallet box.

The storage warehouse described here is of the alveolar type

(by adding mesh side walls) without breaking the load at the various handling points:

  
The pallet frame contains two pallets across the width

The equivalent container must have exactly the same dimensions as the pallet frame, so that the two unit loading modes (pallet frame or container) can be used indifferently, as well on trucks, wagons, ships, warehouses.

4.- The storage room for load units is made up of

  
three parts: a central corridor over the entire height and over the entire length of the building -central corridor having sufficient width to allow the passage of the load unit in its largest dimension-, and two

  
storage located on either side of the corridor, alveolar type storage units to directly receive the load units pushed laterally into each predefined cell.

  
Various systems for routing the load units to their locations are possible, either by stacker bridges - lifts - rails - platform, etc., and do not form part of the present description.

  
5.- Regarding the occupancy of the premises, it is obviously

  
only 2/3 of the total volume of the building.

  
It can be assumed at first glance that this occupancy rate; is insufficient. In this case, two approaches to the problem are possible

traditional warehouses compared to the coefficient of 0.66 given by the present alveolar system.

  
The figure of 0.60 to 0.70 for the occupation of traditional warehouses for storage by forklifts is however generally accepted. Indeed, such warehouses do not have a complete occupation and the corridors, maneuvering areas and all the lost spaces, reduce the average total annual occupation to a figure close to the automatic system.
