It explains the values for vertical vibration under heavy operating
conditions.
Directives on reduction of vibration values in earth moving
machines:
• Perform correct adjustments and maintenance on the machine.
• Avoid jerky movements during machine operation.
• Keep slopes in a perfect condition.
Whole-body vibration can be reduced with the following guidelines:
• Use a machine and equipment of correct type and size.
• Follow the manufacturer’s recommendations for maintenance.
- Tire pressure.
- Brake and steering systems.
- Control elements, hydraulic system and linkage.
• Keep the job site in good condition:
- Remove large rocks or obstacles.
- Fill up ditches and holes.
- Provide a machine and enough time to keep the job site in good
condition.
• Use an operator seat according to the ISO 7096 requirements. Keep
the operator seat in good condition and adjust it correctly:
- Adjust the operator seat and suspension to the operator’s weight and
size.
- Check and maintain the seat adjustment and suspension.
• Perform the following activities smoothly without any jerks.
-Steering
-Brakes
- Acceleration
- Shifting gears
• Move attachments without any jerks.
• Adapt your speed and the itinerary to minimize vibration:
- Travel around obstacles and uneven ground.
- Reduce your speed during machine travel across rough terrain.
• Reduce vibration to a minimum during long work cycles or during
machine operation over long distances:
- Use a machine with a suspension system (for example on the
operator seat).
- Enable the hydraulic oscillation damping if the machine is equipped
with tracks.
- If the machine is not equipped with hydraulic oscillation damping,
reduce your speed to avoid bumps and jolts.
- Load the machine on a truck or trailer to move between job sites.
• Other risk factors can affect drive comfort negatively. The following
measures can improve drive comfort:
- Adjust the operator seat and the control elements to a relaxed body
posture.
- Adjust the rearview mirrors to ensure optimal visibility so you can
adopt an upright seating position.
- Provide breaks to avoid sitting for long periods.
- Do not jump off the cabin.
- Picking up and raising loads repeatedly must be limited to a
minimum.
