(4) Installation area when installing multiple RKU racks with them connected
When connecting multiple racks, calculate the right and left side clearance (a) according to the
formula shown below. Note that the minimum clearance of 200 mm must be secured to perform
maintenance work even though the calculated value is smaller than 200 mm.
[(a):Right and left side clearance (mm)] = (Total weight of storage system (kg)) (1.15 + [(b):Front
and rear side clearance (mm)] 1000) ([Floor load capacity (kgf/m
[Number of connected racks]
Example where the total weight of the storage system is 1,000 kg (including maintenance
equipment), the front and rear side clearance is 1,600 mm, the floor load capacity is 300 kgf/m
and the number of connected racks is two:
1000 (1.15 + 1600 1000) (300 - 10) 1000 - 600 2
= 53.918...
≒ 54
∴ (a)
The calculation of the above example shows that a 54 mm or larger clearance must be secured on
each of the right and left sides of the racks.
However, allow at least 200 mm right and left side clearance (a) to secure the maintenance area.
