Load Table for rotec Heavy Load Gratings :
The calculated values are
concerning to steel no. 355 J2G3 = ST52-3.
ST52-3 steel has a higher
load bearing capacity than ST37-2 and reaches
a higher load bearing capacity by simultaneous
reduction of the weight.

Oscillation
Coefficient :
If the roadway contains
constructive components which
are particularly sensitive to brake loads, the
pressure which results from each wheel must
be multiplied with the factor 1,4
(as brake load).

PRE
DETERMINED : wheel load
=5000[daN] - LOADED area (DIN1072) =200x400[mm]
- distance between the saddles =480[mm] Starting from
the wheel load - we must bring together the
values of the loaded area and the distance
between the saddles. Then we can read the
dimension of the supporting bar on
the left side (60x5[mm]). Due to standard DIN1072,
every loaded area is related to a certain
wheel load. The values for the distance
between the saddles are in red.
