9.12 Vibrations
Vibration values indicated in m/s².
Directive 2002/44/EC of European Parliament and Council on minimum
health and safety requirements regarding exposure of workers to risks
arising from physical agents (vibration).
Indications on hand-arm vibration
Hand-arm vibration is less than 2.5 m/s² during correct vehicle operation.
Indications on whole-body vibration
Whole-body vibration is less than 0.5 m/s² during correct vehicle
operation.
Uncertainty of measurement K has been taken into account for the
specified values.
The degree of vibration is influenced by various parameters.
Some of them are listed below:
• Operator: training, behavior, working method, and load.
• Job site: organization, preparation, surroundings, weather conditions,
and material.
• Machine: version, seat quality, quality of suspension system, attach-
ments, and condition of attachments.
Precise indications on the vibration degrees cannot be made for the
vehicle.
Determination of vibration level for the three vibration axes.
• Under typical operating conditions, use the average vibration values
measured.
• In order to obtain the estimated vibration value for an experienced
operator on level ground, subtract the factors from the average
vibration value.
• In case of an aggressive working method or difficult terrain, add the
environmental factors to the average vibration level in order to obtain
the estimated vibration level.
