Mining Publication: Ergonomic Risk Factors: A Study of Heavy Earthmoving Machinery Operators
Although many studies have shown an association between operating heavy construction equipment and symptoms of musculoskeletal disorders (MSDs), little research has been performed that systematically characterizes the exposure of operating engineers to ergonomic hazards. This study evaluated: 1) vibration at the seat/operator interface; 2) transmissibility of vibration in the Z-axis; 3) psychophysical ratings of vibration level and vibration discomfort; and 4) postural requirements of the job. This paper reports the results of a study performed to evaluate ergonomic exposures among operators of heavy construction equipment. It also provides recommendations for reducing ergonomic exposures such as vibration and postural stress.
