9.12 Vibration
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 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.
• 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
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
during operation of 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 Council on minimum health and safety requirements
regarding exposure of workers to risks arising from physical agents
(vibration).
