VIBRATIONS TO WHICH THE OPERATOR IS SUBJECTED 1
When the earth moving machine is used for its intended purpose, the vibration levels transmitted from the
operator's seat are less than or equal to the vibration tested on the related class of machinery in accordance with
ISO7096.
The actual acceleration value for the hands and arms is less than or equal to 2.5 m/s², the factor of uncertainty for
this vibration value is 1.2 m/s² according EN 12096: 1997.
The actual acceleration value for the body is less than or equal to 0.5 m/s², the factor of uncertainty for this
vibration value is 0.2 m/s² according EN 12096: 1997.
These values were determined using a representative machine and measured during the typical operating
condition indicated below according to the measurement procedures that are defined in the standards ISO 2631/1
and ISO 5349.
OPERATING CONDITION 1
Excavating (Digging-loading-rotating-unloading-rotating).
GUIDE TO REDUCE VIBRATION LEVELS ON MACHINE 1
The following guides can help an operator of this machine to reduce the whole body vibration levels:
1. Use the correct equipment and attachments.
2. Maintain the machine according to this manual.
Q
Tension of crawler (for crawler machines).
Q
Brake and steering systems.
Q
Controls, hydraulic system and linkages.
3. Keep the terrain where the machine is working and travelling in good condition.
Q
Remove any large rocks or obstacles.
Q
Fill any ditches and holes.
Q
Site manager should provide machine operators with machine and schedule time to maintain terrain
conditions.
4. Use a seat that meets ISO 7096 and keep the seat maintained and adjusted.
Q
Adjust the seat and suspension for the weight and size of the operator.
Q
Wear seat belt.
Q
Inspect and maintain the seat suspension and adjustment mechanisms.
5. Steer, brake, accelerate, and move the attachment levers and pedals slowly so that the machine moves
smoothly.
6. Adjust the machine speed and travel path to minimize the vibration level.
Q
When pushing with bucket or blade, avoid sudden loading; load gradually.
Q
Drive around obstacles and rough terrain conditions.
Q
Slow down when it is necessary to go over rough terrain.
Q
Make the curve radius of travelling path as large as possible.
Q
Travel at low speed when travelling around sharp curves.
