Technical data
• 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
•Braking
• 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 (operator seat, for example).
• 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 work 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.
Reference:
The vibration values and calculations are based on the indications made in ISO/TR 25398
Mechanical Vibrations – Guidelines for assessment of exposure to whole-body vibration
during operation of earth moving machines.
