INFORMATION PAGE ON VIBRATION LEVELS OF THE TRACTOR
DANGERS RELATIVE TO EXPOSITION TO VIBRATIONS [4.4] [4.1.a]
WARNING: The vibration level transmitted
to the body as a whole depends on different
parameters, some of them relating to the ma-
chine, others to the terrain, others to the type
of work and to any connected machine and
many specific for the operator. The prevailing
parameters are the type of terrain or work sur-
face, the ground speed and the type of work.
WARNING:
Machine vibrations are transmitted to the
operator, who in some cases may undergo
risks for his/her health and safety. Therefore
you must:
- Make sure that the tractor is in good condi-
tion and that all routine servicing is correctly
and regularly carried out.
- Check that the operator's seat and adjust-
ment systems are in good condition, then ad-
just the seat to the operator's weight and size.
- Evaluate the vibration level transmitted to
the operator from the tractor or from the
tractor-machine assembly and schedule work
hours so as to alternate suitable rest periods
concerning exposure to vibrations.
IMPORTANT: More information on Whole Body Vibra-
tion (WBV) on agricultural tractors can be found in more
specific publications. In order to correctly estimate values
based on your daily work on the tractor, a specific measure
instrument is required, such a three-axis accelerometer
applied to the seat.
NOTE: Visit the dedicated Internet web sites for further
information and documentation on risks of whole body
vibration.
In compliance to EU Directive 78/764/CE the following table shows vibration levels measured on seats, in aws.
