Abstract

The mechanization of olive harvesting is very important both to reduce the costs of productionand to assure the oil quality because the manual harvest does not allow to operate at the righttime and also need a long period to be completed. The use of portable shakers, that arespreading more than others typologies, can give a solution to the problem. However, the use ofsuch equipment may involve risk of exposure to hand-transmitted vibration. The aim of thisstudy was to assess the level of exposure to hand-arm vibration of the operators using portableshakers (reference standards UNI EN ISO 5349-1:2004, Italian Low Decree 81/2008). Theresearch presented here concerns the definition of a test bench for the execution of laboratorytests and the experimental tests in the open field under real operating, in both cases by applyingthe hardware components and the related software development activities previously realized bythe authors. The experimental tests were performed with shakers commonly used in olivesharvesting in order to collect and characterize vibration data in terms of intensity. Theseinformation were afterwards used to real time monitor vibrations and consequently evaluatehealth risks. Total vibration values measured in the laboratory using the test bench andmeasured in the field were not statistically significant different. This allows to state that the testbench realized by the authors can be applied to measure the vibrations transmitted by handheldshakers to the hand-arm operator’s system as a "standard system" for eventual certification ofthis type of machines for the defence of agricultural workers' health.
