Vibration levels 1
When used for its intended purpose, levels of vibration for the earth-moving machine transmitted from the opera-
tor’s seat are lower than or equal to the tested vibrations for the relative machinery class in compliance with ISO
7096.
For PC210/230-8
The actual acceleration value for the hands and arms is less than or equal to 2.5 m/s², the uncertainty for this
value is 0.49 m/s² according to EN12096:1997.
The actual acceleration value for the body is less than or equal to 0.5 m/s², the uncertainty for this value is 0.24 m/
s² according to EN12096:1997.
For PC240-8
The actual acceleration value for the hands and arms is less than or equal to 2.5 m/s², the uncertainty for this
value is 0.53 m/s² according to EN12096:1997.
The actual acceleration value for the body is less than or equal to 0.5 m/s², the uncertainty for this value is 0.28 m/
s² according to EN12096:1997.
These values were determined using a representative machine and measured during the typical operating condi-
tion indicated below according to the measurement procedures that are defined in the standards ISO 2631/1 and
ISO 5349.
Operating condition:
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 con-
ditions
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
