Calculation of the permissible load of a wall-mounted shelving unit
Fig. 99 Typical representation with 5
shelves and base shelf
Different console depths and axial dimensions
mean different load capacities of the shelves
(see Chapter 7.1.1).
Since several shelves of different depths can be
inserted, an average value of the shelf depths
DAverage
must be calculated.
Formula:
DAverage
=
TS / n
DAverage = average depth of all shelves inserted
TS = Total shelf depths
N = Number of shelves
Example calculation based on Fig. 81:
Sum of TS of the depths of all inserted shelves
(excluding base shelf)
TS=400+400+400+500+500=2,200 mm /
15+15+15+20+20=85 in
Number of inserted shelves n = 5
=>
DAverage
=2,200 mm (85 in) / 5=
440 mm (17 in)
Using this average, the table below shows the
corresponding load total of these 5 shelves
(excluding base shelf).
Thus average shelf depth
DAverage
440 mm / 17 in => 375 kg / 827 lb total load of
inserted shelves

The shelf depth may not exceed the base depth, i.e. for base depths of 400 mm / 15
in or 500 mm / 20 in, the maximum permissible total load of the shelves is 375 kg /
827 lb (see table above)!
For base depths of 600 mm / 24 in, 700 mm / 28 in or 800 mm / 31 in, the average
shelf depth must be calculated.
