Noise emission level
– DFG 660-690, S80: 73 dB (A)*
– DFG S90: 70 dB (A)*
– TFG: 71 dB(A)*
*+/- 4 dB(A) depending on the truck's equipment
in accordance with EN 12053 as harmonised with ISO 4871.
Z
The noise emission level is calculated in accordance with standard procedures and
takes into account the noise level when travelling, lifting and when idle. The noise
level is measured at the level of the driver's ear.
Vibration
in accordance with EN 13059.
Z
The vibration acceleration acting on the body in the operating position is, in
accordance with standard procedures, the linearly integrated, weighted
acceleration in the vertical direction. It is calculated when travelling over thresholds
at constant speed (standard truck version). These recordings were taken on a
single occasion and must not be confused with the human vibrations of the "2002/
44/EC/Vibrations" operator directive. The manufacturer offers a special service to
measure these human vibrations, see "Human vibration measurement" on
page 198.
Z
The vibration that is characteristic for vibrations of the body cannot be used to
determine the actual load caused by vibrations during operation. That depends on
the operating conditions (condition of the travel routes, method of operation, etc.)
and should therefore be determined on site at a suitable location. Hand/arm
vibration must always be determined without exception, even if the values do not
indicate any hazard at all, as in this case.
