Özet
Objective: The objective of this study was to conduct experiments by using 3D motionanalysis system to reveal ergonomic exposures during apple hand picking.Material and Method: The study was carried out in the ergonomics laboratory locatedat ATB (Leibniz Institute for Agricultural Engineering and Bioeconomy Potsdam e.V.)in Germany with an artificial dwarf apple tree. Body postures, especially upper armelevation, were determined by a 3D motion capture system. Evaluations were madeaccording to ISO 11226 standard and RULA classification.Results: Average upper arm elevation changed between 27.86° and 33.60°. Timespent with elevated arm above 200, the base limit suggested by standards was foundto be significant for entire experiments as 77% on average of the process time. It wasestimated that 5 to 6 hours within 8 hour shifts per day may be spend with elevatedarms more than 20°.Conclusions: More detailed information was obtained in comparison to observationalmethods. This technique allows to determine the exact values of the arm positionsdepending on time intervals. It can also be used to find out other awkward posturessuch as trunk and head inclination and for any other work process.
