(3) Reference matrix of clearances between racks
Values of the right and left side clearance (a) and the front and rear side clearance (b) that are
illustrated in Figure 2-3 are shown by total weight of the storage system in the following tables.
Find a value of the necessary right and left side clearance (a) according to the expected front and
rear side clearance (b) (1,600/1,800/2,000 mm) for the installation location and the calculated total
weight of the storage system (x).
