collecting and sharing information on whole-body vibration (WBV) in mobile machines
Whole-body vibration is a health hazard for operators of construction machinery. The level of whole-body vibration exposure on the operator is governed by three different factors; performance of the suspension system of the machine, planning of the work and the skills of the operator.
This video shows the potential in bringing down the level of whole-body vibration exposure by educating operators of backhoe loaders.
The Forestry Research Institute of Sweden (Skogforsk) have carried out some experiments on reducing fuel consumption. They obtain a good results and an indication that the level of whole-body vibrations decreased with improve fuel economy [1]. This video shows the experiment (in swedish).

Whole-body vibration (WBV) is the exposure of vibrations/accelerations on the human operator of some kind of mechanical device. Typically commercial vehicles such as construction equipment, agricultural tractors, combines, trucks and forestry machines does affect the operator with a certain level of vibrations.
Be definition whole-body is transmitted through the seat (for seated persons) or feet (for standing persons) [2].

In June 2010 researchers from the The National Research Centre for Working Environment in Denmark and University of California at San Francisco, USA published a new report based on several years of observations [3].
Abstract
Background
Whole-body-vibrations are often associated with adverse health effect but the long term effects are less known. This study investigates the association between occupational exposures to whole-body vibrations, and subsequent transition to disability pension.
Methods
A total of 4215 male employees were followed up for subsequent disability pension retirement. Exposure to whole-body-vibration was self-reported while new cases of disability pension were retrieved from a national register.
Results
The hazard ratio (HR) for disability pension retirement among men exposed to whole-body-vibrations was 1.61 (95% confidence interval (CI) 1.07-2.40) after adjustment for age, smoking habits, BMI, physical job demands and awkward work postures. In our model, with the available explanatory variables, 5.6% of the male disability pension cases were attributable to whole-body-vibrations.
Conclusion
Exposure to whole-body-vibrations predicts subsequent disability pension retirement. Continued reduction of whole-body-vibrations may reduce the number of new cases of disability pension.
