Abstract

Manual lifting is one of the common activities in industries. Due to the manual lifting activities, the worker may be exposed to low back pain and shoulder pain. The aim of this study is to develop mathematical model for psychophysical experience, pain level and heart rate with respect to load mass, lifting height and twist angle for Malaysian male while performing manual lifting activities. Manual lifting activities may leads to mental and physical fatigue. Thus, the motivation, productivity and efficiency of workers may be affected. The questionnaire survey to a Metal Stamping Industry was conducted to identify lifting techniques and health problems experienced by the male workers. Then, a Laboratory Based Experiment was applied to investigate the effect of load mass, lifting height and twist angle on psychophysical experience, pain level and heart rate of male subjects in manual lifting. Statistical analysis tools associated with descriptive statistics, comparative statistics and regression statistics were used to analyze the data. Based on results, this study found that load mass has identified as vital contributor to psychophysical experience, pain level and heart rate. Additionally, nine mathematical models have been developed and validated through historical data and experimental data. Based on statistical analysis, there is a good agreement between the results of mathematical model, historical data and experimental data. Therefore, this study concluded that the models are reliable to be used for predicting the effect of psychophysical experience, pain level and heart rate with respect to lifting height, load mass and twist angle in manual lifting. This study suggests that environmental factors such as the workplace temperature and lighting should be considered in the future study.
