COMPARISON OF WHOLE-BODY VIBRATION EXPOSURES ON OLDER AND NEWER HAULAGE TRUCKS AT AN AGGREGATE STONE QUARRY OPERATION

摘要

Exposure to whole-body vibration (WBV) and the postural requirements of the job have been identified as important risk factors in the development of musculoskeletal disorders of the back among workers exposed to a vibratory environment. This paper focuses on preliminary results of WBV data collected for two groups of haulage trucks - four older trucks from manufacturer A (MFR-A) and two newer trucks from manufacturer B (MFR-B).
