Whole body vibrations in older IMT tractor models

Abstract

During their work agricultural tractor drivers are exposed to various negative influences including vibrations. They are vibrations generated in engines, and which are transmitted to the driver body (whole body vibrations) through the seat, floor and controls of a vehicle. The exposure to these vibrations over a long period of time can lead to serious health problems. Therefore, it is important to estimate risk to the health that comes from whole body vibrations in order to develop mechanisms of protection. The measurements of vibration levels in older tractor models of the manufacturer Industry of Machinery and Tractors (IMT) Belgrade showed that the work of more than one hour poses significant risk from daily exposure to vibrations, high above values legally permitted. In those cases, an employer must take organisational and technical measures in order to reduce the levels below permitted values.
