2.7. Vibrations and noise
Noise tests have been carried out under the most unfavourable conditions to study the effects on the operator. The level of
acoustic pressure weighed (A) at work places does not exceed 70dB(A) for each electrical model.
For the Diesel engine models, the level of acoustic pressure weighed (A) at work places does not exceed 106dB(A), the level of
acoustic pressure at ground control panel does not exceed 85dB(A), the level of acoustic pressure at platform control panel
does not exceed 78dB(A).
As to vibrations in ordinary working conditions:
▪
The average weighted quadratic value in frequency of the acceleration which the upper members have to withstand is
below 2.5 m/sec² for each of the models to which this Use and Maintenance manual refers.
▪ The average weighted quadratic value in frequency of the acceleration which the body has to withstand is below 0.5
m/sec² for each of the models to which this Use and Maintenance manual refers.
