    Abstract:
    Loading and unloading of aircrafts involves lifting, moving, and carrying of heavy cargo in unfavourable body positions and in narrow spaces. This transport work was subjected to an investigation in a big airport. Forty-three male transport workers and foremen were studied during 46 total shifts. The type of activity was recorded by using the standardized procedure, the so-called "Arbeitswissenschaftliches Erhebungsverfahren zur Tätigkeitsanalyse" (AET). For time and motion analysis, body positions were recorded by continuous observation during the total shift. For typical activities the energy expenditure was determined. The strain caused by transport work was estimated by recording the heart rate with a portable cardiocorder during the total shift. The results show that both dynamic and static work are involved in the loading and unloading of aircrafts. The heart rate varied characteristically according to the body position and to type of activity. The body position was mainly determined by the height of the bellies (from 0.61-1.97 m) of different aircrafts. An additional influence due to weight carrying could be observed only in body positions with low energy expenditure. Recommendations for changing the height of the bellies or to the appropriate selection of workers were made.
