The thesis focuses on the study of psycho-physiological workload and exposure to noise and vibration when working with the Albach Diamant 2000 chipper. The aim is to analyze and determine the influence of different factors on psycho-physiological workload, measured through the heart rate, and the workers exposure to noise and vibration during chipping and to compare the values found with the permissible limits. The measurements were carried out during chip production on an Albach Diamant 2000 chipper for one recording day during which four cycles of chip transport were carried out. We found that psycho-physiological workload was higher during non-productive time than productive time, and lower than the tolerable values during all work operations. Similarly, the whole-body vibration during the chipping operation do not exceed the daily exposure limit. Exposure to noise was higher during non-productive time than during productive time and higher during chipping logs than during chipping branches. Exposure to noise during non-productive time exceeded both exposure values and, when no personal protective equipment was worn, it also exceeded the exposure limit value of 87 dB(A) with a value of 87,6 dB(A). According to the results of the study, it can be concluded that the greatest risk to the health of the worker when working with the chipper is posed by exposure to noise, since it may exceed the daily exposure limit value for noise in the case of prolonged delays due to working means that are primarily intended for machine maintenance and the non-use of personal protective equipment.
