Evaluation Of Occupational Exposure To Whole Body Vibration In Forest Harvesting Machines [avaliação Da Exposição Ocupacional À Vibração De Corpo Inteiro Em Máquinas De Colheita Florestal]
DOIAbstract
In Brazil there are few studies that quantify the levels of exposure to whole body mechanical vibration on forest harvesting machines. This study was conducted in the region of Campinas, in areas of eucalyptus harvest from a cellulose and paper company, to quantify the levels of random vibration to which operators are exposed to in three types of timber harvesting machines – Feller Buncher, Slash Grapple and Skidder – during the workday. A Larson Davis triaxial meter integrator model HVM 100 was used and the results compared to the recommendations of ISO 2631-1: 1997 (in health criterion) and Directive 2002/44 of the European Community. The Feller-Buncher had a magnitude of vibration equivalent of 1.12 m.s-2, and the recommended maximum exp...
