Vibrations

The risks linked to long exposure to strong or high frequency vibrations depend on the type of stress, sometimes concerning the skeleton and muscles, sometimes the vascular and nervous systems. Medicine classifies them into two main categories of vibrations: hand-arm vibrations (common to walk-behind and ride-on machines) and whole-body vibrations (specific of ride-on machines).

Hand-arm vibrations: ISO 5349-1

Vibrations

Exposure to high frequency vibrations may damage the vascular system (often resulting in loss of finger sensitivity) or the nervous system (sometimes resulting in partial paralysis of the thumb’s radial nerve).

Exposure to the vibrations of heavy tools (the typical example is the pneumatic drill) may damage the osteo-articular system (resulting in arthrosis or bone decalcification).
It’s important therefore to consult the Use and Maintenance booklet, which always comes with the machine, to see the level of vibrations transmitted to the hand-arm system and choose, whenever possible, the machine with the lowest values.

Check the level of vibrations transmitted to the hand-arm system (expressed in m/s²) in the machine Use and Maintenance booklet and, if possible, choose the one with the lowest level! The level of vibrations should be measured in compliance with ISO 5349-1.

The level of hand-arm vibrations of our machines is certified by an accredited laboratory to offer the highest reliability of the declared values.

Whole-body vibrations: jolts ISO 2631-1

Vibrations

he whole-body vibrations of a person are commonly called jolts. When these are very strong or prolonged, they may lead to spinal problems, that is mainly bone and muscular disorders.
These problems may also be due to the incorrect position of the operator (resulting from bad machine use habits), or machine design that fails to take into account the basic principles of ergonomics.

Check the level of whole-body vibrations (expressed in m/s²) in the machine Use and Maintenance booklet and, if possible, choose the one with the lowest level! The level of vibrations should be measured in compliance with ISO 2631-1.

Ensure the machine EC declaration states that it has been designed in compliance with directive EN 12100, and that the principles of ergonomics have also been applied.

Whole-body vibrations of our machines are certified by an accredited laboratory to guarantee the highest reliability of the declared values.
