520  ‎$a‎To study the physiological and psychophysical costs of symmetric and asymmetric manual materials handling, two tasks were performed by 30 industrial subjects. In both tasks, box weight and handle position were varied. The symmetric task, lifting and lowering between floor and conveyor, showed handles to be beneficial. The asymmetric task was palletizing and depalletizing 36 boxes between a pallet and a conveyor. All handle positions were better than no handles, but the best handle position changed from asymmetric for 9 kg boxes to symmetric for 13 kg boxes
