Vibrations
Vibrations to which the hands and arms
are exposed
The following value is valid for all truck mod-
els:
●
ā
w
< 2.5 m/s
2
NOTE
It is mandatory to specify the hand-arm vibra-
tions, even where the values do not indicate
any danger, as in this case.
General comments: Vibrations to which
the body (legs) is exposed
The values to which the body (legs) is ex-
posed apply to driving with the operator on
board the truck.
The value complies with Harmonised Europe-
an Standard EN 13059 (Safety of industrial
trucks — methods for measuring vibration).
CAUTION
The value expressed above can be used to compare
forklift trucks of the same category. It cannot be used
to determine the operator's daily exposure to vibra-
tions during real operation of the truck; these vibra-
tions depend on the conditions of use (floor condi-
tions, method of use etc.) and therefore daily expo-
sure must be calculated using data from the place of
use.
