9.12 Vibration
Vibration values indicated in m/s².
Directive 2002/44/EC of European Parliament and Coucil 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 machine operation.
Indications on whole-body vibration
Whole-body vibration is less than 0.5 m/s² during correct machine
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 strain.
• Work 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
machine.
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.
Note:
For further vibration indications, refer to the indications in ISO/TR 25398
Mechanical Vibrations – Directive on Estimation of whole-body vibration
when traveling earth moving machines. This publication uses measuring
values of international institutes, organizations and manufacturers. It
contains information on whole-body vibration for operators in earth moving
machines. For more information on the vibration values of the machine,
refer to Directive 2002/44/EC of European Parliament and Coucil on
minimum health and safety requirements regarding exposure of workers
to risks arising from physical agents (vibration).
It explains the values for vertical vibration under heavy operating
conditions.
