Variation in exposure to whole-body vibration for operators of forwarder vehicles-aspects on measurement strategies and prevention

To estimate the health risk from exposure to WBV in forwarders, the results suggests that exposure assessment strategies should include several measurements on the same forwarder and driver during various operational conditions. The results also indicate that both r.m.s.-magnitude and VDV shall be used for risk assessment, since they are influenced by various factors. Selecting another forwarder model can reduce the magnitude of WBV during travelling, suggesting opportunity for technical improvements. During travelling empty, WBV magnitude can be reduced by changing terrain type. During travelling loaded, the magnitude can be reduced by adjust the way the vehicle is driven.
