Whole Body Vibration Exposure to Crane Operator’s

Whole body vibration (WBV) has been linked to lower back disorders (LBD’s). The purpose of this study is to determine whether crane operators are exposed to whole body vibration (WBV). If exposure exists then, do they exceed a current consensus standard. This information will be used to determine whether WBV should become a larger discussion item when purchasing cranes and or rebuilding. This information can also be used to make the case for seat replacement or at the very least a qualification to consider when purchasing replacement seats. While many studies exist relating WBV to LBD, I could not find information regarding the quantification of the vibration. Is there little vibration? Does it exceed a consensus standard? If it does exceed a consensus standard then it warrants greater attention when rebuilding cranes including their seats as well as purchasing new ones. Eight different cranes were tested in this study. A variety of manufacturers were tested. Manufacturer of crane # of Samples
