Abstract
A comprehensive lifting model (CLM) for the evaluation and design of m anual tasks was developed in two stages using 11 task, personal and en vironmental variables. In the first stage, the model was built using t he psychophysical data. In the second stage, discounting factors of va rious variables were tested and adjusted using the physiological and b iomechanical data. Two lifting indices are proposed to evaluate liftin g tasks for a group of workers (relative lifting safety index or RLSI) and for an individual worker (personal lifting safety index or PLSI).
