• Description:
  Shipyards and other construction and manufacturing establishments that require the extensive use of heavy powered hand tools have introduced the use of counterweighted mechanical arm systems to alleviate mechanical stressors on tool operators. Preliminary shipyard trials suggest that by reducing the stressors associated with certain tool operations, these ergonomic interventions may increase productivity rates by 50% or more for tasks such as overhead grinding. While the results of our earlier study on the use of pneumatic grinders in conjunction with a counter-balanced mechanical arm indicated that the arm offered small to moderate reductions in hand-transmitted vibration (HTV), the reduced HTV exposures can be offset by increases in work cycle times; these interventions may actually increase daily HTV exposures in some cases. In the present study, we completed some preliminary evaluations of the effects of adding suspension mechanisms to the mechanical arms on grinder vibrations in a simulated work task.
