Última Operators’ exposure to noise and vibration in the grass cut tasks: comparison between private and public yards CIGR Journal Calvo, Angela; Deboli, Roberto; Preti, Christian. During the green maintenance, the grass cut tasks require the operators to use machines (especially lawn tractors, mowers, blowers and brush cutters) which transmit them high levels of noise and vibration. The requests of the Directive 2003/10/EC for the operators’ noise exposure are difficult to be applied in seasonal variable activities, as grass cut tasks are. The same problem exists in case of the workers’ exposure to vibration sources. Aim of this work was to compare the noise and vibration operators exposure of a public yard with a private one in the grass cut tasks. Data were collected using the requested standards considering all the noisy and vibrating sources of the operators. Moreover, the different work organisation in the two yards was...

Ano: 2016 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/3554 Hand arm vibration generated by a rotary pick-up for table olives harvesting CIGR Journal Deboli, Roberto; Calvo, Angela; Gambella, Filippo; Preti, Christian; Dau, Riccardo; Clara Casu, Eleonora. The manual harvest of olives is one of the most expensive operations in the table olives production, but the use of the electric hand-guided machines triples the productivity.  The development of these new machines leads to changes in the harvesting methodologies and in the operator’s working behavior.  These items may also affect the hand-arm vibration (HAV) transmitted to the operators during the work.  Aim of this study is to evaluate the hand-arm vibration transmitted to the operator using an experimental electric labor saving machine with rotary combs with teeth of different dimensions covered by silicon to minimize the damage to the drupes.  Moreover, the olives removal forces have been analyzed to understand if the force necessary to detach the...
