WEIGHT BALLAST VARIATION IN COMPARISON TO THE WIND SPEED
Weight Ballast [N]
Fig. 6-2 Weight Ballast variation in comparison to the wind speed for AMS-8061
For wind speed below 15 m/s (corresponding to about 54 km/h) the stability is ensured by the weight of
the apparatus self and therefore it is not required ballast bags.
The weight of ballast bags filled with water can be maximum 390 N; the maximum wind speed that does
not cause the overturning of the AMS-8061 is 20 m/s (corresponding to about 72 km/h).
The weight of ballast bags filled with sand can be maximum 720 N; the maximum wind speed that does
not cause the overturning of the AMS-8061 is 23 m/s (corresponding to about 83 km/h).
The AMS-8061 must be firmly fasten by nylon wind strays for wind speed above 23 m/s.

It is necessary to calculate the speed and pressure of the wind in the
place of installation; through the table 7-1 it is possible to determine if
it is necessary to use the ballast bags with their full weight or to
fasten the nylon wind strays.
